| 摘 要： | 投影法是一种多指标决策和评价的方法，可应用于水体水质间的比较与排序，但它不能定性评价水体水质，无法确定水体的污染情况。本文对该模型作了改进，具体方法为将水质标准值设为虚拟评价对象与考察对象一同进行投影，以标准的投影值为基准，通过标准区间嵌入法确定水体毋质等级值，根据各水质等级值进行评价及排序。以福州山仔水库为例，对水库的富营养化程度进行综合评价，评价结果与模糊隶属函数法基本相符，评价结果合理且方法简单明了。

| Abstract: | Project is an useful method of multi - indicator pollcydecision and evaluation, now it is applied in comprehensive evaluation and sequencing of water quality. It is used to evaluate with an example Shanzi Reservoir of Fuzhou. The evaluation results in terms of projection value and standard grades index. Compared with the results of fuzzy membership function,the results demonstrate that the method is eredibile; further more, the method is simple and easy to be understood. |

| Keywords: | projection the reservoir of Shanzai projection value standard grades index |
