Research on wetland ecological restoration and landscape regeneration design in coal mining subsidence areas:Taking Pan'an Lake in Xuzhou City as an example
The ecological environment in coal mining subsidence areas is relatively fragile due to historical legacy and development and construction issues.Taking the Pan'an Lake wetland in Xuzhou City as an example,based on the analysis of the basic situation and characteristics of the subsidence area,the ecological modification and landscape regeneration design of the area were carried out using sustainable development theory and grey fuzzy theory,and the ecological function model of the area was reconstructed.The results showed that the ecosystem of Pan'an Lake wetland is relatively fragile,with an environmental performance index weight of 0.673,and its diversity,richness,and hierarchy in plant landscape layout still need to be improved(weigh＞0.05).The study analyzed in detail the governance measures from the aspects of land leveling,water system connectivity,functional zoning optimization,and plant ecological landscape layout.The ecological application effect of the above design content and restoration measures was significant,injecting new impetus into regional ecological environment governance and economic development.
