针对长江生态大保护需要构建有利于流域生态优化的土地利用方式这一战略需求,文章采用生态压力和生态效率表征国土空间生态优化,以土地利用与生态优化冲突较为突出的长江流域江苏省为例,基于2009—2017年该省13个地级以上市的面板数据,建立空间滞后计量模型,实证检验了土地资源配置、利用方式对国土空间生态优化的影响效应。结果表明:（1）耕地占比下降、建设用地占比上升,会显著提升生态效率,但也会显著加大生态压力;（2）林地占比上升,能同时显著降低生态压力和提升生态效率;（3）建设用地节约集约利用能显著提升生态效率,且对生态压力的加剧效应较小;（4）耕地机械化显著提升了生态效率,但也...

The precondition of ecological conservation in Yangtze River is the construction of land use patterns which is beneficial to the ecological optimization,this paper uses ecological pressure and ecological efficiency to characterize the land ecological optimization. Using the panel data of 13 prefecture-level cities in Jiangsu Province from 2009 to 2017,the article empirically tests the effect of land allocation and utilization on the land ecological optimization by establishing a spatial lag model. Results show that: 1) The decrease in the proportion of cultivated land and increase in the propo...
