Construction and zoning of ecological'resilience-risk'safety status classification in the Central Yunnan Urban Agglomeration
摘要
Abstract
[Objective]This study aims to assess the resilience of urban agglomeration ecosystems and the risks they face,in order to promote the coordination between resource development and ecological environmental protection.[Methods]Taking the Central Yunnan Urban Agglomeration as the study area,quantitative assessment models for ecological resilience and ecological risk were developed from a landscape pattern perspective.The spatiotemporal dynamics of ecological resilience and ecological risk from 2002 to 2022 were systematically analyzed.The TOPSIS method was employed to construct the ecological'resilience-risk'safety status classification,and corresponding zoning management strategies were proposed.[Results](1)The ecological resilience level in the study area exhibited a spatial pattern of'strong in the west,weak in the east',with the average value rising from 0.369 2 in 2002 to 0.381 in 2022,indicating an overall upward trend.(2)Ecological risk displayed a spatial distribution of'higher in the center,lower in the east and west',with the average value stable at about 0.04.Although the overall trend showed improvement,high-risk areas around Kunming City increased,with their proportion rising from 1.13%to 1.49%.(3)From 2002 to 2022,the overall ecological safety status of the study area declined.The proportion of areas in ideal and good status decreased from 1.21%and 50.42%to 0.54%and 40.74%,respectively,while the proportion of areas in risky and sensitive status increased from 9.67%and 13.89%to 11.37%and 16.95%,respectively.[Conclusion]Over the past 20 years,the overall ecological safety status in the study area declined,with reductions in the proportion of areas in ideal and good status and increases in risky and sensitive status.Future zoning control strategies should be developed for different status areas to enhance ecological resilience,reduce ecological risk,and ensure ecological safety and sustainability.关键词
