Abstract: In this paper, analysis of the current pollution status and integrated quality of Le′an river was carried out on the basis of recent hydrology, water quality, and pollution source investigations. It was summarized that the main water pollutants were CODCr and NH3N, with the major pollution source being from farming and livestocks and municipal wastewater. Based on the above described facts, water environmental control targets have been proposed, and a collective idea was put forward that is to control the effluent with the discharging standard, to build wastewater treatment plant, to control notpoint pollution sources, to restore ecosystem , and to improve the supervision and administration on items of Le′an river water environment.

Key words: Le′an river, water environment, pollution, comprehensive administration
