摘　　要：菜坨子岛位于大连市长海县,为无居民海岛,功能定位为渔业用岛。依据无居民海岛生态系统的特点和渔业用岛功能定位,文章使用压力-状态-响应模型设置3层指标体系,对菜坨子岛生态状况进行评价。指标评价方法采用专家评价法及单因子环境质量指数法、综合评价指数法等计算各级权重值和指标值。基于2015年现场调查数据,采用层次分析法对压力-状态-响应模型进行计算,得出菜坨子岛年生态状况分值及评价结果。结果表明,菜坨子岛总体状态为“优”(分值为0.8111)。此外,经过对评价指标进一步优化后,可将该评价方法推广到对其他渔业用无居民海岛的生态状况评价,为其开发和保护提供依据。Caituozi Island is located in Changhai County of Dalian,which is an uninhabited island with the function of fishery.According to the characteristics of uninhabited island ecosystem and the function of fishery island,the pressure-state-response(PSR)model with three-layer index was built to evaluate the ecological status of Caituozi Island.Expert evaluation method,environmental quality index of single element method and comprehensive evaluation index method were applied to calculate weight value and index value of each level indexes.Based on field investigation data in 2015,ecological status score of Caituozi Island was calculated by using the analytic hierarchy process of PSR model.The result showed that the status of Caituozi Island was“Excellent”(The score was 0.8111).In addition,the evaluation method could be extended to assess the ecological status of other uninhabited islands for fishery by further optimizing the evaluation indexes.
