云南高原湖泊流域种植业面源污染物的流失特征分析
Non-point Source Pollutants Loss of Planting Industry in the Yunnan Plateau Lake Basin, China
摘要
Abstract
Non-point source pollution of planting has become a major factor affecting the quality and safety of water environment in our country.In recent years,some studies show that the loss of nitrogen and phosphorus in agricultural chemical fertilizers has led to more serious non-point source pollution.By means of the loss coefficient method and spatial overlay analysis,the loss amount,loss of strength and its spatial distribution characteristics of total nitrogen,total phosphorus,ammonium nitrogen and nitrate nitrogen were analyzed in the Fuxian Lake,Xingyun Lake and Qilu Lake Basin in 2015.The results showed that:The loss of total nitrogen was the highest in the three basins,following by ammonium nitrogen,nitrate nitrogen and total phosphorus,which the loss of intensity range were 2.73～22.07,0.003～3.52,0.01 ～2.25 kg· hm-2 and 0.05～ 1.36 kg· hm-2,respectively.Total nitrogen and total phosphorus loss were mainly concentrated in the southwest of Qilu Lake,west and south of Xingyun Lake.Ammonium nitrogen and nitrate nitrogen loss mainly concentrated in the south of Qilu Lake,south and north of Xingyun Lake.The loss of nitrogen and phosphorus was mainly derived from cash crops and rice.Therefore,zoning,grading and phased prevention and control schemes were proposed,in order to provide scientific basis for controlling non-point source pollution in the study area.关键词
