Non-point source pollution from agriculture and rural region is becoming one of the main causes of water pollution in China.Exceed inputs of fertilizer and pesticides,lower use efficiencies of fertilizers and irrigation water,and fewer treatments of wastewater from rural animal husbandry and living sewage are believed to be responsible for this serious situation.Constructed wetlands have been widely proposed as an effective measurement to control non-point source pollution from agriculture.In 1994,several constructed wetlands were originally built to mitigate pollutants of nitrogen and phosphorus runoff from arable land to Dianchi lake in Yunan Province.This paper summarized the researches on constructed wetlands established to control agricultural non-point source pollution in some important freshwater area such as Dianchi lake,Taihu lake,Guanting reservoir.We also reviewed the application of constructed wetlands for treating animal husbandry wastewater.Ecological function of constructed wetlands is receiving more and more attentions in China,because it is identified a simple and robust solution to reduce water pollutants from agricultural non-point sources.
