| 摘 要： | 属性识别理论是根据实测资料构造样本空间矩阵,利用评价指标进行样本属性分类和构造样本属性矩阵,用熵理论确定指标权重,然后进行水质评价.根据塔里木河各测站的资料,建立了属性识别模型,评价了塔里木河的水质;结果表明塔里木河枯水期水质较差,丰水期水质良好,平水期水质一般,评价结果符合塔里木河水质的现状.属性识别理论概念清晰,计算简单,评价结果比较客观.

| Abstract: | Sample space rectangular battle formation is formed by using attribute distinction theory according to determine data, samples is classified by using evaluation index. Entropy weight of evaluation index is determined by using Shannon entropy theory. Attribute distinction model of source and main river in Tarim river is built, caits water quality is calculated. The results indicate water quality in high-water period is better, water quality in low water period is worse. Main river of Tarim river needs synthesize administer. Attribute distinction model can get scientific and reasonable results, have better practical value. |
