摘　　要：以辽宁朝阳阎王鼻子水库为研究对象,搜集2017—2019年水库及其所在区域的社会、经济、环境统计数据,结合国内外生态安全评估研究理论,运用“驱动力-压力-状态-影响-响应”(DPSIR)模型构建阎王鼻子水库生态安全评估指标体系(4个维度、12大项和25小项),评估阎王鼻子水库的生态安全指数。结果表明,2017—2019年该水库生态安全指数(ESI)逐年提升,生态服务功能达到优秀水平,水库的生态安全处于良好状态。未来需要进一步增强水库的“山-水-林-田-湖-草”一体化功能,配套水库周边的生态环境基础设施,有效防止生态环境退化;制订水库环境保护与管理模式,全面保障水库生态安全,推动辽宁朝阳阎王鼻子水库健康、稳定、持续发展。Yanwangbizi Reservoir was selected as the research object,which was located in Chaoyang,Liaoning Province.The statistical data of this reservoir including the society,economy and environment from 2017 to 2019 were collected.Referring to the theories of ecological security assessment at home and abroad,we applied the“driving force-pressure-state-impact-risk”model(DPSIR)and created index system(4 dimensions,12 major items and 25 minor items)for assessment on the ecological safety index(ESI)of Yanwangbizi Reservoir.The results showed that ESI of this reservoir increased during 2017-2019.The ecological service function of this reservoir reached the high level.The ecological security of this reservoir was in a good state.In the future,the integrated functions of mountains-rivers-forests-farmlands-lakes-grasslands of this reservoir should be further improved.The ecological environment infrastructure around this reservoir were constructed,in order to effectively prevent the degradation of the ecological environment.We should formulate the environmental protection and management mode of this reservoir,guarantee the ecological safety of this reservoir,promote the healthy,stable and sustainable development of Yanwangbizi Reservoir in Chaoyang,Liaoning Province.
