从流域生态系统结构以及土地利用角度构建由陆域环境影响、水域生态健康状况、流域生态服务功能组成的水府庙水库流域生态安全评价体系，利用层次分析法和综合指数法对该流域进行生态安全评估。结果表明，基于土地利用的水府庙水库流域生态安全等级为三级，总体处于一般安全状态。陆域环境影响一般，水域生态健康状况处于中等安全，流域生态服务功能较好。流域内土地利用不合理以及污染负荷较大对水府庙水库流域生态安全造成一定的压力，使水体开始呈现富营养化状态，影响水府庙水库流域的水体环境和生态服务功能，已成为威胁水府庙水库流域生态安全的隐患。

The watershed ecological security assessment system of Shuifumiao reservoir in Hunan province was established from the perspective of watershed ecosystem structure and land use, including land environmental impact, water ecological health status and watershed ecological service function.The AHP method and the comprehensive index method were used for watershed ecological security assessment.The results show that the comprehensive ecological security of the watershed is in GradeⅢ, overall in general safety state.The effect of land environment is of general level, the water ecological health is at a medium security, and the watershed ecological service function is good.Irrational land use and great pollution load cause some pressure on the ecological security of Shuifumiao reservoir basin.The resulted water body eutrophication can influence the water environment and ecological service function of the basin, which has become the hidden trouble of safety threat to ecological security of Shuifumiao reservoir basin.
