摘要
云南地处山地高原,地形复杂,植被丰富但覆盖不均衡,通过对其生态脆弱性评价,衡量其生态的可持续发展状况。本研究采用SRP(敏感-恢复力-压力)模型,选取14个指标因子构建评价模型,通过AHP结合熵权法确定指标权重,并用地理探测器进行驱动力分析。结果表明:云南省的生态脆弱性受自然因子影响最为显著,总体上呈现出西北高、西南低、滇中纵横交错的特点。
Yunnan is located in a mountainous plateau,with complex terrain,rich vegetation but uneven coverage.Through the evaluation of its ecological vulnerability,the sustainable development of its ecology is measured.This study adopts the SRP(sensitivity resilience stress)model,selects 14 index factors to build the evaluation model,determines the index weight through AHP and entropy weight method,and uses the geographic detector to analyze the driving force.The results show that the ecological vulnerability of Yunnan Province is most significantly affected by natural factors,and generally shows the characteristics of high in the northwest,low in the southwest and crisscross in the middle of Yunnan.
