摘要
湿地水体富营养化形势日益严峻,引入距离函数将主观权重与客观权重结合,改进了传统的熵权法。根据白洋淀12个水域2015年5月监测数据,由改进熵权法得到的评价结果表明:圈头水域轻度富营养化;郭里口、大张庄、留通、枣林庄、光淀张庄、关城、前塘和采蒲台8个水域为中度富营养化;王家寨、安新桥和端村3个水域为重度富营养化。
Wetland eutrophication situation was increasingly serious. The integration of subjective and objective weightswas achieved and the traditional entropy weight method was improved with the distance function. According monitoring datain may,2015,12 areas of Baiyangdian wetland,the evaluation results showed：Quantou was light eutrophication;Guolikou、Dazhangzhuang、Liutong、Zaolinzhuang、Guangdianzhangzhuang、Guancheng、Qiantang and Caiputai were moderate eutro-phication;Wangjiazhai、Anxinqiao and Duancun were severe eutrophication.
