农业发展与环境政策对农业面源污染的实证分析——以三峡库区重庆段为例

An Empirical Study of Agricultural Development and Environmental Policies on Agricultural Non- point Source Pollution in Three Gorges Reservoir Area of Chongqing

农业自身、农业发展趋势、农业经济发展与环境政策都会不同程度的影响农业面源污染。利用三峡库区重庆段的面板数据,采用计量分析方法,定量分析农业发展和环境政策对农业面源污染的影响。研究结果表明:农业产业化经营政策、国家财政对化肥和粮食的直接补贴政策对农业面源污染存在正向影响,即会增加面源污染;农业技术推广补贴、农业生态工程建设、种植业结构调整和测土配方施肥政策存在负向影响,会减缓农业面源污染;农业科技投入、农田水利基本建设投入和农业环保投入对农业面源污染不存在显著的相关。

Agriculture itself, the agricultural development tendency, the agricultural mental policy will affect the agricultural non - point source pollution in different degrees. the influence of agricultural development and environmental policies on agricultural non using the econometric analysis method and the panel data of the Three development and environ- Using, this paper analyzes -point source pollution by search results show that the policies of agricultural industrialization, national finance on chemical fertilizer and grain direct subsidy have a positive effect on the agricultural non -point source pollution, which wiU increase the non - point source pollution. Agricultural technology promotion subsidies, agricultural eco - engineering eonstruc- tion, the adjustment of planting structure and ence. They will slow the agriculture non -point vestments in agricultural science and technology mental protection and agricultural formula fertilization by soil testing policy are the negative inilu- source pollution. There are no significant correlation between the in- , farmland water conservancy construction and agricultural environ- non- point source pollution.
