摘要：
Dongting Lake is an important lake wetland in China. How to quickly and accurately obtain the basic information of the Dongting Lake ecological wetland is of great + significance for the dynamic monitoring, protection, and sustainable utilization of the wetland. Therefore, this article proposes the information extraction of the Dongting Lake ecological wetland based on genetic algorithm optimized convolutional neural network (GA-CNN), an analysis model combining genetic algorithm (GA) and convolutional neural network (CNN). Firstly, we know the environmental information of Dongting Lake, take Gaofen-1 image as the data source, and use normalized vegetation index and normalized water body index as auxiliary data to preprocess the change detection of remote sensing images to obtain high-precision fitting images. GA-CNN is constructed to efficiently extract the information of the Dongting Lake ecological wetland, and the Relu excitation function is used to improve the phenomenon of gradient disappearance and convergence fluctuation so as to reduce the operation time. Logistic regression is used for feature extraction, and finally the automatic identification and information extraction of the Dongting Lake ecological wetland are realized. The research results show that the method proposed in this article can more deeply dig the information of ground objects, express depth features, and has high accuracy and credibility.

摘要：
With the deepening of the concept of sustainable development, people have become more and more aware of the important role of the ecological environment in human development. To protect and build the ecological environment, the harmony between man and nature has become the common choice of all countries in the world. As a means of adjusting the relationship between stakeholders in the use, protection and construction of the ecological environment, and maintaining and improving ecosystem services, ecological compensation has received increasing attention from all over the world. The theoretical research and practice of ecological compensation has become a hot research issue in the 21st century. one. Payment for ecosystem services is an institutional arrangement for the purpose of protecting and sustainable use of ecosystem services, and adjusting the interests of stakeholders based on economic means. It is aimed at protecting the ecological environment and promoting the harmonious development of man and nature. Value, ecological protection cost, development opportunity cost, and the use of government and market means to regulate the public system of interest relations between stakeholders in ecological protection. According to the status quo of Dongting Lake Eco-Economic Zone and the ecological environment, this study constructs a regional ecological compensation standard model, evaluates the value of ecosystem services and other indicators, determines the objects of regional ecological compensation, and builds a framework of regional ecological compensation mechanism. Introduce a coordination degree model to study the relationship between the construction of an ecological compensation system and the government's ecological purchase mechanism. The research results show that the regional ecological compensation mechanism framework has a certain degree of operability. The compensation model should be based on the government ecological purchase mechanism, supplemented by market compensation, and adopt multiple methods to implement regional ecological compensation scientifically.
