Research On Landscape Performance Evalua Tion And Optimization Strategy Of Coal Mi Ning Subsidence Wetland Park

As the main energy source in China,coal plays an important role in social development.However,coal mining subsidence wetlands formed by large-scale coal mining due to surface subsidence and accumulated water have caused great harm to the local environment and production.In recent years,with the deepening of ecological restoration research on coal mining subsidence wetlands,the quantitative assessment on sustainable development of coal mining subsidence wetland parks after ecological restoration have become new research hotspots,which are of great significance to the construction of urban ecological civilization and environmental restoration.Landscape performance evaluation is one of the ways to quantify the sustainable development value of completed projects.This article focuses on coal mining subsidence wetland parks evaluation,objectively and systematically with its landscape performance so as to propose targeted optimization strategies.This paper takes coal mining subsidence wetland park as research object,based on performance theory and sustainability theory,as well as the performance theory and sustainable theory,combined with LPS landscape performance indicators and relevant laws and regulations of coal mining subsidence wetland park,constructs a landscape performance evaluation index system for the coal mining subsidence wetland parks,and uses AHP to determine the index weight.Comprehensive index methods were also utilized to construct the evaluation model to judge the sustainable development of coal mining subsidence wetland parks.This paper takes the Pan’an Lake National Wetland Park as an example to conduct an empirical study,applying the established coal mining subsidence wetland park evaluation method to Pan’an Lake National Wetland Park.Through the preliminary investigation and analysis of landscape performance evaluation elements,the obtained data is calculated by the comprehensive index method It is concluded that the sustainable development situation of Pan’an Lake National Wetland Park is in good condition and a specific analysis is carried out to provide a basis for a final optimization strategy.Finally,through the evaluation results,combined with the current situation of the Pan’ an Lake National Wetland Park,the Pan’ an Lake National Wetland Park optimization strategy was proposed from three aspects:habitat creation,human landscape,and landscape development space.This paper provides reference for planned or completed coal mining subsidence wetland park.The paper has 56 pictures,28 tables and 82 references.
