摘要：
We study the relationship between green credit and ecological welfare performance, green credit’s mechanism, and future trends of ecological welfare performance in China. We aim to determine whether the green credit policy has a positive or negative effect on ecological welfare performance and to give suggestions about green credit for emerging markets, with China as an example. These problems are evaluated with two empirical models by using quadratic and interaction terms, as well as a time series model, ARIMA(2,3,2). The results show that the relationship between green credit and ecological welfare performance is an inverted U shape, and ecological welfare performance peaks when loans approach 2934.2 billion yuan, which equals 441.7446 billion dollars, corresponding to loans between 2015 and 2016. In addition, national income and ecological footprint have a suppressive effect on the impact of green credit on ecological welfare performance, and lifespan can positively affect the mechanism. Moreover, the result of ARIMA(2,3,2) corresponds to previous results and indicates that the ecological welfare performance will fluctuate within a range if green credits continue to be issued.

摘要：
Rural landscape resources are important ingredients of rural revitalization and modernization in developing countries and regions. Evaluation methods play a crucial role in the development planning, design, transformation, and protection of these resources. However, there has been a lack of research on the evaluation of rural landscape resources, especially from the perspective of rural revitalization. Based on previous evaluation methods and expert consultations on landscape planning and design, we proposed a new approach for evaluating rural landscape resources by establishing a new index system and using the Analytic Hierarchy Process (AHP) and probabilistic linguistic Cloud Model. To demonstrate its applicability and effectiveness, we applied our model to the case of a village (Xiapu) in Guangdong, China, determined the parameter set of its rural landscape resources, and obtained related results showing that the method is practical and can reflect the value of resources objectively and efficiently. Based on this model, further suggestions are provided to improve the design and other utilizations of rural landscape resources.

摘要：
Urban green space, comprising parks, fields, woodlands, and other semi-natural areas, is a fundamental component of urban ecosystems. The determination of the relationship between urban green space and urban sprawl is necessary to understand urbanization and the provision of urban ecosystem services. It has been hypothesized that the center of urban (i.e., population and economic) areas in fast-growing cities would migrate toward urban green space over time. To test this hypothesis, urban expansion and urban green space expansion were examined in five cities in China and five cities in the U.S. that were experiencing high rates of growth. Landsat images of those cities from 2000 to 2017 were combined with annual population and economic data and used to quantify the extent and migration of the urban green space. These data were analyzed using the center of gravity method by Grether and Mathys and circular statistics were used to determine the relationship between urban green space and urban expansion. Eight out of the ten cities showed a divergent pattern, i.e., the population and economic centers moved in a different direction to that of the urban green space. The movement of the mean centers of the urban green spaces in the U.S. cities was more consistent than that of the Chinese cities. Over 18 years, the movement of urban green space and urban expansion in the 10 cities showed a synchronous growth trend; however, the proportion of urban green space in the cities decreased. The urban expansion rate exceeded the population growth rate, which led to problems with an unreasonable urban sprawl that is likely to deplete the provision of ecosystem services in the future. In conclusion, the centrifugal forces of urban green space that lead to the movement of population and economic centers away from green spaces play a larger role in urban change than the centripetal forces that pull these centers toward urban green space.

摘要：
The appropriate ecological operation method is suggested in order to create a harmonious human settlement environment and achieve the sustainable development of residential areas. The key to determining whether the model can be successfully implemented is now the stakeholders. Scholars feel that stakeholders in the urban development process should sustain collaboration, and they suggest collaborative measures because they have successfully identified these parties. Nevertheless, there are distinctions between the specialized research of ecological operation stakeholders and the disregard for internal differences of related groups. In order to examine the relationship strength and network density, structural location, and role interaction, this article employs social network analysis to examine the cohesiveness, relevance, reciprocity, transitivity, hierarchy, and agency of the stakeholder relationship network in the ecological operation. Interest disagreements, solutions, and recommendations among participants encourage the effective application of the ecological operating model. The study demonstrates that there are no factions, and that weak links dominate the stakeholder relationship network in ecological operations, exhibiting a “core-periphery” relationship structure. High relevance, high reciprocity, and high transmissibility describe the relationship network. Although the network’s overall power is dispersed, each group’s power is centralized. Residents and social organizations in residential areas are in a poor position, since governments at all levels have strong control over them. In order to optimize relationships and collaborative governance, which is helpful for implementing the ecological operation mode and realizing harmony and oneness between man and nature, the study explored the relationship network structure and features of stakeholders in the ecological operation.

摘要：
To investigate the fatigue performance of the stud connectors of steel-concrete structures, fatigue crack propagation analysis and fatigue life calculation were carried out. Firstly, the finite element model with the initial crack based on linear elastic fracture mechanics (LEFM) was established, and the parameter analysis of the stress intensity factors (SIFs) of the studs and cracks with different geometric sizes was performed. Then, the propagation with mixed-type fatigue crack and I-type fatigue crack of the stud were calculated, and the variation of effective SIFs with the fatigue crack depth was analyzed. Finally, the flow chart of stud fatigue life evaluation which considers crack initiation and stable propagation was presented, and the short stud of steel-UHPC composite structures was taken as an example and verified. The calculation results show that the fatigue crack propagation type and the initial crack have an obvious influence on the fatigue life of the stud. It has acceptable accuracy that the fatigue life of short stud in UHPC simulated by considering the crack initiation. The critical damage parameters are greatly affected by the fatigue stress amplitude, and the initiation life of fatigue crack can account for more than 90% of the total fatigue life. This paper can provide a reference for evaluating the fatigue performance of studs in steel-concrete composite structures. Accurate evaluation of the fatigue life of stud connectors conforms to the concept of sustainable development.

摘要：
Rainfall is one of the core components of the water cycle in terrestrial ecosystems and is closely related to hydrothermal balance, plant and animal growth, and stability of the whole ecosystem. Long-duration rainstorms can alter the soil structure of forest ecosystems and affect the spatial distribution of soil moisture, thus affecting the water supply from the soil to trees and being one of the factors that increase the vulnerability of forest ecosystems. In recent years, changes in rainfall patterns have normalized prolonged heavy rainfall in the mountainous areas of North China. However, there are few reports on the response of soil water at different depths to historically long rainstorms in forested areas. By quantifying the relationship between precipitation characteristics and soil water, the soil water transport patterns of Platycladus orientalis (PO), Quercus variabilis (QV) and Pinus tabuliformis (PT) during the long-duration rainstorms of 21–22 July 2012 were evaluated separately, and the roles of different plants in response to the historically long rainstorm were determined. The results showed that (1) the response of different forest stands to rainfall had a lag. Among them, the soil water of PO and PT were less affected by rainfall and could maintain a relatively stable state. (2) The soil moisture transport trend of PO was significantly greater than that of other vegetation zones and covered the whole process of rainfall. Under the three typical vegetation covers, there was a continuous zero-flux plane in the soil at each observed depth (the direction of soil moisture flow is more stable over the rainfall period), but there was no regular transport trend. (3) The root system was an important factor, influencing the differences in soil moisture response of the three vegetation types. QV had a higher average effective water recharge rate than lateral cypress and oleander and could better utilize the water recharge from storm water.

摘要：
Agroforestry integrates woody perennials with arable crops, livestock, or fodder in the same piece of land, promoting the more efficient utilization of resources as compared to monocropping via the structural and functional diversification of components. This integration of trees provides various soil-related ecological services such as fertility enhancements and improvements in soil physical, biological, and chemical properties, along with food, wood, and fodder. By providing a particular habitat, refugia for epigenic organisms, microclimate heterogeneity, buffering action, soil moisture, and humidity, agroforestry can enhance biodiversity more than monocropping. Various studies confirmed the internal restoration potential of agroforestry. Agroforestry reduces runoff, intercepts rainfall, and binds soil particles together, helping in erosion control. This trade-off between various non-cash ecological services and crop production is not a serious constraint in the integration of trees on the farmland and also provides other important co-benefits for practitioners. Tree-based systems increase livelihoods, yields, and resilience in agriculture, thereby ensuring nutrition and food security. Agroforestry can be a cost-effective and climate-smart farming practice, which will help to cope with the climate-related extremities of dryland areas cultivated by smallholders through diversifying food, improving and protecting soil, and reducing wind erosion. This review highlighted the role of agroforestry in soil improvements, microclimate amelioration, and improvements in productivity through agroforestry, particularly in semi-arid and degraded areas under careful consideration of management practices.

摘要：
The green growth mode of modern economy is affected by both policy and market, but previous studies have lacked a comparison between the two effects on green economy development. Which is the leading factor of green growth: policy or market? Using the Panel Smooth Transition Regression (PSTR) model and the twelve-year data of more than 200 prefecture-level cities in China, we compared and analyzed the linear and non-linear effects of environmental regulation and marketization degree on green total factor productivity (GTFP). The results show that: (1) both environmental regulation and marketization degree have a non-linear promoting effect on GTFP. (2) GTFP is mainly market-driven rather than policy-guided. (3) Environmental regulation and marketization promote the improvement of GTFP through the industrial upgrading effect and the innovation development effect, respectively. This paper makes up for the comparative analysis gap of factors in the field of green growth and extends from the single determination of influencing factors to the importance of the comparison of influencing factors with the transition perspective. The conclusions provide a reference for the green development of countries and regions, emphasizing the importance of green development policies adapting to local conditions and time and providing evidence for market-oriented green economy development.

摘要：
Cadmium (Cd) is a highly toxic pollutant and a nonessential element for plant growth. Here, we investigated the levels of malondialdehyde (MDA), H2O2, sugars, and the activity and gene expression of antioxidant enzymes and sugar metabolism-related enzymes in the mycelia of Pleurotus eryngii grown in the presence of 0, 0.5, 1, 1.5, 2.0, and 4.0 mg center dot L-1 Cd. Raising Cd concentration resulted in increases, followed by decreases in the levels of malondialdehyde (MDA) and H2O2 in the mycelia. The maximum concentrations of MDA and H2O2 reached 318.61 and 7411.40 mu mol center dot L-1, respectively, at a Cd concentration of 1 mg center dot L-.(-1) Antioxidative enzymes (superoxide dismutase (SOD), catalase, glutathione peroxidase (GPX), and ascorbate peroxidase (APX)) activities peaked at 1 mg center dot L-1 Cd. Furthermore, Pleurotus eryngii produced trehalose, glucose, fructose, and maltose in the fermentation broth in response to Cd stress. The levels of trehalose, arabinose, and fructose in the fermentation broth decreased continuously. The levels of glucose increased continuously, whereas those of maltose first increased and then decreased. Gene expression level of chitin synthase, glucose-1-phosphate uridyl transferase peaked significantly at 2 mg center dot L-1 of Cd, while that of trehalase 2 is 0.5 mg center dot L-1, and those for fructose-diphosphate aldolase, glyceraldehyde-3-phosphate dehydrogenase, reached the maximum at 4 mg center dot L-1.

摘要：
As trade partners, China in Southeast Asia and Ghana in Africa both play a major role in the China-Africa economic and trade cooperation and have strengthened their bilateral trade. The trade cooperation between China and Ghana has progressed, and there currently exists a large agricultural product trade between the two countries. China has become one of Ghana's largest trading partners in recent decades, and bilateral cooperation has become stronger. This paper analyses the comparative advantage and complementarity of trade in agricultural products between China and Ghana in terms of twenty major agricultural products from 2016 to 2020, based on the revealed comparative advantage index, trade complementarity index, and their status quo. The results showed that the trade volume of China-Ghana agricultural products has continuously increased, and China is currently in a surplus state, but their total agriculture trade volume proportions had been decreasing. From the perspective of comparative advantage and complementarity, the results showed that the comparative advantage and complementarity coexist, but their comparative advantage is more obvious showing strong competitiveness. The result further shows that the comparative advantage of Ghana was stronger than that of China and the complementarity of China's exports and Ghana's imports of agricultural products has not been fully exploited; likewise, the complementarity of China's imports and Ghana's exports of agricultural products has not been fully exploited since 2018, and there is a large potential for further cooperation and development. Finally, based on the current situation and our analysis of agricultural trade between China and Ghana, suggestions were put forward to seek new and continuous development opportunities for agricultural trade cooperation between the two countries.

Pedestrian and bicyclist involved crashes;Crash frequency models;Bivariate models;Transit stops
摘要：
Introduction: Walking and cycling for transportation provide immense benefits (e.g., health, environmen-tal, social). However, pedestrians and bicyclists are the most vulnerable segment of the traveling public due to the lack of protective structure and difference in body mass compared with motorized vehicles. Numerous studies are dedicated to enhancing active transportation modes, but very few studies are devoted to the safety analysis of the transit stops, which serve as the important modal interface for pedestrians and bicyclists. Method: This study bridges the gap by developing joint models based on the multivariate conditional autoregressive (MCAR) priors with distance-oriented neighboring weight matrix. For this purpose, transit-oriented design (TOD) related data in Los Angeles County were used for model development. Feature selection relying on both random forest (RF) and correlation analysis was employed, which leads to different covariates inputs to each of the two joint models, resulting in increased model flexibility. An integrated nested Laplace approximation (INLA) algorithm was adopted due to its fast, yet robust, analysis. For a comprehensive comparison of the predictive accuracy of models, different evaluation criteria were utilized. Results: The results demonstrate that models with correlation effect perform much better than the models without a correlation of pedestrians and bicyclists. The joint models also aid in the identification of the significant covariates contributing to the safety of each of the two active transportation modes. The findings show that population density, employment density, and bus stop density positively influence bicyclist-involved crashes, suggesting that an increase in population, employment, or the number of bus stops leads to more active modes involved collisions. Practical Applications: The findings of this study may prove helpful in the development and implementation of the safety management process to improve the roadway environment for the active modes in the long run.(c) 2022 The Author(s).

摘要：
This research explores the influencing factors of students’ attitude toward self-regulated learning (SRL) within blended learning setting (BLS). The theoretical model is developed based on the Theory of Planned Behavior (TPB) and two dimensions are proposed: major satisfaction (MS) and perceived teacher support (PTS). It studies how these variables affect students’ attitude toward SRL within BLS, directly or indirectly. The proposed model is validated by employing a partial least squares structural equation modeling approach (PLS-SEM) based on the valid data collected from 604 students from three private universities in China. The results suggest that (a) the constructs, including the PTS and TPB (attitude, subjective norm and perceived behavior control), have a positive impact on student attitude toward SRL within BLS; (b) SRL attitude has a positive intermediary effect on the relationship between PTS and SRL intention, and between MS and SRL intention, respectively; (c) perceived behavior control (PBC) has a positive intermediary effect on the relationship between MS and SRL intention; (d) subjective norm (SN) has a positive intermediary effect on the relationship between PTS and SRL intention. The findings have useful implications for teachers, higher institution administrators, researchers, and higher education policy-makers in enhancing students’ learning within the blended learning context.
