漳卫南运河流域水生态安全指标体系构建及评价

ESTABLISHING INDICATOR SYSTEM AND EVALUATING ECOLOGICAL SECURITY IN ZHANGWEINAN RIVER BASIN

基于PSR物理概念模型建立水生态安全指标体系,利用粗糙集和逼近于理想解法建立水生态安全评价模型.针对漳卫南运河流域中潞城市、新乡县和德州市进行水生态安全评价.结果表明:漳卫南运河上游潞河城市最好,中游新乡县其次,下游德州市最差,3个县市均属于水生态安全评价标准的极差级别.这一评价结果为漳卫南流域的水生态安全建设提供了相关的科学依据.

Water ecological security index system was established by PSR physical concept model, roughsets and TOPSIS（technique for order preference by similarity to ideal solution）were used to establish waterecological security evaluation model. The proposed model was used to evaluate ecological security evaluation in Lucheng city, Xinxiang county, Dezhou city of Zhangweinan river basin. Data showed that ecological security state in descending order was- Xinxiang county in midstream of Zhangweinan river basin, Dezhou city in downstream of basin, Lucheng city in upstream of basim The aquatic ecosystem state was very poor for all three counties. The evaluation data provided scientific evidence for ecological safety of basin construction
