摘　　要：为准确对岸堤水库水生态安全状况进行定量评价并明确限制因素,采用DPSIR模型并结合水库自身特点,构建起共19个指标的评价指标体系,其中包括环境数据、遥感数据以及社会经济数据。同时,采用改进的群组AHP法确定各指标权重,对岸堤水库2015年的水生态安全状况做出评价。结果表明:(1)岸堤水库水生态安全指数为0.620,人为干扰较小,服务功能稳定;(2)方案层各元素标准化得分分别为0.547、0.630、0.539、0.833、0.636;(3)岸堤水库面临的主要生态问题为,流域内亟待提高的经济水平对水生态安全构成威胁,施肥强度过大,消落带湿地面积退化,生活污水处理率低。In order to quantitatively assess the water eco-security and determine the limiting factors of Andi Reservoir, an evaluation index system consisting of statistical data, remote sensing data and environmental monitoring data was constructed based on the DPSIR model. Then, the improved group AHP method was used to determine the weight of each index, and the water eco-security situation of Andi Reservoir in 2015 was evaluated. The results showed that:(1)The water ecological safety index of Andi reservoir was 0. 620,and the water ecological security situation is good.(2) The standardized scores of the elements of scheme layer were 0. 547,0. 630,0. 539,0. 833 and 0. 636,respectively.(3)The main ecological issues faced by Andi reservoir were the threat of increasing economic level, excessive fertilization, degraded wetland(fluctuating belt) and low sanitary sewage rate.
