摘要
生态系统遭受破坏后,其恢复力及对外界压力的适应性可通过生态敏感性进行定性评价,这有助于识别地区生态环境问题并为生态规划提供参考。本文以衡阳县为研究区,结合主要生态环境问题,综合评价土地荒漠化、水土流失、滑坡灾害及冻融侵蚀等的敏感性,探讨其时空演变特征,以切实保护区域生态环境。
After the ecosystem is damaged,its resilience and adaptability to external pressures can be qualitatively evaluated through ecological sensitivity,which helps identify regional ecological environmental issues and provides reference for ecological planning.Taking Hengyang County as the research area and considering the main ecological and environmental issues,this paper comprehensively evaluates the sensitivity of land desertification,soil erosion,landslide disasters,and freezethaw erosion,and explores their spatiotemporal evolution characteristics to effectively protect the regional ecological environment.
