岷江流域地表水水质的模糊综合评价

岷江是长江上游的一个重要支流，其水质安全对维持成都平原正常的生产生活起着至关重要的作用。采用模糊综合评价的方法，对岷江流域14个地表水监测断面的水质状况进行了综合评价。结果表明：在14个监测断面中，处于清洁和未污染程度的断面占50％，主要位于岷江流域的上游和下游，其水质状况较好；处于重污染的断面占29％，主要位于岷江流域的中游，水质状况较差。因此，需要加强流域综合治理尤其是对岷江中游的治理，以确保岷江流域的水质安全。

Surface Water Quality Assessmet in Minjiang River Basin by Fuzzy Synthetic Evaluation Method

Minjiang River was an important branch of the upriver of Changjiang River.The water quality of Minjiang River played a key role in securing the normal social process of producing and living in Chengdu Plain. In this paper, the fuzzy synthetic evaluation method was presented to access the surface water quality of a total of 14 monitor sections in Minjiang River Basin. The results indicated that there were 7 sections which accounted for 50% of the total sections in none or lowly polluted status. These sections were mainly distributed in the upriver and downriver of Minjiang River Basin. Meanwhile, there were 4 sections which accounted for 29% of the total sections in highly polluted status. And these sections were maiuly distributed in the middle reaches of Minjiang River Basin. By analyzing the results, more emphasis should be paid on the integrated basin administration, especially on the treatment of the middle - river of Minjiang River for securing the safety of surface water quality in Minjiang River Basin.
