摘要(Abstract)：

针对生态敏感性评价中指标选择、权重计算步骤存在的主观性,片面性的问题,以乐山市为例,基于压力-状态-响应模型构建评价指标体系,运用主成分分析(PCA)-熵权法组合权重模型对选取的20个评价指标因子赋权。结合层次分析法对乐山市2018年生态环境进行评价研究。结果表明:乐山市生态敏感性指数分布存在明显空间差异,乐山市大部分地区属于不敏感、较不敏感等级,占研究区总面积的67.18%;其次为极敏感等级,占研究区面积的14.4%;一般敏感和较敏感等级所占面积最少,分别是9.84%和8.58%。压力-状态-响应模型全面考虑了生态影响因素,PCA-熵权法组合权重计算也弥补了层次分析法主观性强的缺陷,为生态敏感性分析提供了一种可行的思路。
