In this paper, the water quality status, the character of pollution fountain and contamination of Fuxi River of Zigong urban section were studied. According to water quality monitoring data for many years, permanganate index, ammonia nitrogen, total nitrogen, total phosphorus and chemical oxygen demand(COD) were as monitoring items. On the basis of the water quality results in the last two months, the valuation of water quality was made by using single-index assessment method. As indicated by the results, pollution degree of different monitoring sections was different, and overall water quality was standard V. The content of total nitrogen and total phosphorus obviously exceeded the national standard, and they were reached to the dangerous loads of eutrophication. Water pollution is serous. Based on the analysis results, measures of contamination gross control of Fuxi River were put forward in order to provide scientific evidences for improving water quality, reinforcing management.
