摘要
以鄱阳湖生态经济建设为契机,开展对鄱阳湖地区农业非点源污染问题的研究。利用GIS技术,对鄱阳湖地区进行土地分类调查,确定农业化肥、农药流失为鄱阳湖地区的主要农业非点源污染源。通过对农业化肥、农药的施用量和施用强度的调查并进行变化趋势分析,计算出二者各自污染物排放量,探讨其对鄱阳湖地区水生态环境的影响,并结合鄱阳湖地区农业生产的实际,提出相应的非点源污染控制的技术措施——最佳管理措施,可为鄱阳湖的综合开发和治理提供科学依据和参考。
The study on non -point source (NPS) pollution of Poyang Lake is very important during the period of Poyang Lake ecological economic construction. Land use situation of the Poyang Lake was studied based on GIS. By analysis of the using amount and intensity of chemical fertilizers and the status of pesticides, the discharging amount of the pollutants from the two sources was estimated, and the influence on the ecological environment of Poyang Lake is explored. Analysis of the data shows that chemical fertilizers and pesticides are the main agricultural non - point source pollutions in Poyang Lake area. And the corresponding non - point source pollution control technologies- the best management measures are suggested.
