| 摘 要： | 根据新疆博尔塔拉蒙古自治州环境监测站对艾比湖5个代表性的监测断面最近5年的水质实测资料,结合熵权法和国家地表水环境质量标准系统地建立了属性识别模型,运用属性计算和属性得分详细评价了艾比湖的水质.模型评价结果表明:艾比湖的水质污染主要为氨氮、磷、砷的污染.就空间而言,湖心2水质较好,没有出现V类水质,其次为喇叭口,博乐河口与精河河口水质较差;就时间而言,2003年各监测断面水质均属I类,之后逐渐恶化,到2008年半数以上的监测断面属于V类水质,且与改进密切值法的评价结果比较,结果较吻合.采用属性识别模型评价湖泊水质,概念清晰,计算简单,评价结果客观、合理,可以反映出艾比湖水质的现状,是湖泊水质评价中简便实用的评价方法之一.

| Abstract: | With the development of economy,water body pollution become more and more serious and the water quality deterioration has become an increasingly important issue.According to the water quality measured data of five monitoring sections from the environmental monitor station of the Xinjiang Bortala Mongol Autonomous Prefecture in recent five years,the entropy method is used to determine the weight of every evaluation index,this paper built the attribute distinction model systematically and evaluated water qual... |
