摘　　要：随着经济发展,水污染日益加剧,水体富营养化问题日益突出。将改进的属性识别模型结合熵权法对新疆艾比湖的富营养化状况进行了评价,并与综合营养状态指数法和改进密切值法进行比较,结果吻合。该方法计算简便,评价结果客观、合理,为湖泊水质的富营养化评价提供一种简便实用的评价方法。With the development of economy, water body pollution become more and more serious and the water body eutrophication question has become an increasingly important issue. This article applies the attribute distinction method combined entropy weight to eutrophication evaluation in the Xinjiang Ebinur; Meanwhile, comprehensive nutrition index method and modified osculating value method as compared with the evaluation results, the evaluated results are better consistent with the two methods mentioned above in the article. This method calculate simply, evaluation result are objective and reasonable, and provides one simple practical assessment method for the lake water quality＇ s eutrophication appraisal.
