Water pollutants in Lanzhou section of Yellow River can enter the agricultural ecosystem along with irrigation, migrate among water-soil-bio systems and be accumulated in organisms including human body. These pollutants can not only cause serious influences on the ecological environments of both sides of the Yellow River but also cause various damages to animals and plants and even to human health. In the present paper, we review the progress of studies on environmental pollution monitoring, ecological risk assessment and ecological remediation in the agricultural ecosystem in Lanzhou section of the Yellow River. We also summarize the existing problems and provide some countermeasures.
