| 摘 要： | 分别根据三角形白化权函数和梯形白化权函数对长江流域各站点的水污染现状进行灰色评价，对评价结果进行比较，发现三角形白化权函数和梯形白化权函数的使用在灰色评价中利用最大隶属度原理得到的结果是一样的，这与灰色理论及模糊数学理论是一致的。若要精确到求出评价值进行排序，结果不完全相同，但差别不大。与其他方法比较利用梯形白化权函数计算尽管复杂但效果更好些。

| Abstract: | According to the linear relationship among the measuring data of Yangtze River,the index weight is decided by mean-variance method,triangle whitenization weight function and trapezoid whitenization weight function are established respectively to make grey evaluation for the present situation of water pollution of Yangtze River,and finally the expectation results are approximate.This explains that whitenization weight function has bigger flexibility,subjectivity according to the grey theory and fuzzy theory. |
