摘  要：
沱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及周边地区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,对沱江流域15个地表水监测断面的水质状况进行综合评价,结果表明:在15个监测断面中,处于清洁状态的有6个,占40%;处于未污染的有4个,约占26.7%;处于轻污染和中污染的各有1个,分别约占6.7%;处于重污染的有3个,占20%。处于清洁和未污染的断面主要位于沱江流域的中游,其水质状况较好;处于中污染和重污染的断面主要位于沱江流域的上游和下游,水质状况较差。需要加强流域综合治理尤其是对沱江上游和下游的治理,以确保沱江流域的水质安全。

摘  要：
Tuojiang River is an important branch of the upriver of Yangtze River.The water quality of Tuojiang River plays a key role in securing the normal social process of producing and living in Chengdu plain and interrelated regions.The fuzzy synthetic evaluation method is presented to access the surface water quality of a total of 15 monitor sections in Tuojiang River basin.The results indicate that there are 6 sections which account for 40% of the total sections in none or lowly polluted status.These sections are mainly distributed in the middle reaches of Tuojiang River basin.Meanwhile,there are 4 sections which account for 26.7% of the total sections in highly or moderately polluted status.And these sections are mainly distributed in the upriver and downriver of Tuojiang River basin.By analyzing the results,more emphasis should be paid on the integrated basin administration,especially on the treatment of the upper and lower region of Tuojiang River for securing the safety of surface water quality in Tuojiang River basin.
