鄱阳湖区农业面源污染形成机制研究

以农业面源污染与经济发展、产业结构、经营规模、劳动力转移之间有着内在联系为基本理论假设，以江西省鄱阳湖区25个县区的相关数据为研究样本，建立相关的计量经济模型。研究结果表明：农民人均纯收入与农业面源污染呈正相关；牧业增加值占农业增加值比重、人均耕地面积、非农就业比重和单位面积耕地农业劳动力数量与农业面源污染呈负相关。

Mechanism Forming of Agricultural Non-point Source Pollution in Poyang Lake Region

This paper assumed that intrinsic theoretical links must exist between agricultural non-point source pollution and other factors like economic development, industrial structure, operation scale and the transfer of labor force. It validated the proposed model through studying the sample data of 25 counties in Jian-gxi＇ s Poyang Lake area. The results show that the per capita net income of rural residents is positively linked with agricultural non-point source pollution while a negative correlation exists among the proportion of agricultural added value, the per capita area of cultivated land, the proportion of non - agricultural employment, and agricultural labor force per unit area of cultivated land.
