江西省农业面源污染空间分布格局

农业面源污染正成为生态环境的主要问题,但其分散性、广泛性等特点又决定了其治理难度较大。江西目前仍处于农业现代化的起点阶段,农业面源污染日益严重。该研究通过对江西省农业的种植业、畜禽业和水产养殖业的污染源进行调查,利用ArcGIS软件,对江西省农业面源污染进行了空间化和数字化处理。结果表明,江西省农业污染源主要是畜禽养殖业,其次是种植业,水产养殖业污染日趋严重。该研究为江西省农业面源污染评估提供了科学依据。

Spatial Distribution Pattern of Agricultural Non-point Source Pollution in Jiangxi Province

The agricultural non-point source pollution is becoming an increasingly important eco-envionrmental problem,it is difficult to control due to its dispersive and extensive characteristics.Jiangxi Province is still at the initial stage of agricultural modernization,but its agricultural non-point source pollution is exacerbating.According to the investigation on the pollution sources of planting,animal husbandry and aquaculture in Jiangxi Province,the ArcGIS software was adopted to analyze the spatial and digital features of agricultural non-point source pollution.As indicated by the results,the principal pollution source is animal husbandry,then followed by planting,the pollution from aquaculture is becoming more and more serious.The study provided scientific basis for the evaluation of agricultural non-point source pollution in Jiangxi Province.
