宜昌市农业面源污染与经济增长关系研究

Analysis of the Relationship between Economic Growth and Agricultural Non-Point Source Pollution in Yichang City

宜昌市近几年开始推进农业面源污染综合治理工作,寻找生态环境与农业发展之间的平衡。为了解宜昌市农业面源污染与经济增长之间的关系,本文选取2000~2018年农业面源污染四个指标的相关数据,运用环境库兹涅茨曲线理论,通过Stata16.0软件进行实证分析,得出以下结论:第一,宜昌市农业面源污染中的四个变量均与人均农业产值之间存在典型的倒“U”型曲线关系且拐点在研究时序中均已到来;第二,从污染源来看,化肥污染和畜禽粪便污染的治理应该成为宜昌市农业面源污染治理工作的重点。在此基础上,本文提出相关建议。

In recent years,Yichang city,Hubei Province has begun to promote the comprehensive management of agricultural non-point source pollution,seeking a balance between the ecological environment and agricultural development.In order to understand the relationship between agricultural non-point source pollution and economic growth in Yichang city,the relevant data of the four indicators of agricultural non-point source pollution from 2000 to 2018 are selected,and the environmental Kuznets curve theory is used to conduct empirical analysis with stata16.0 software.The conclusions are as follows:First,there is a typical inverted U-shaped curve relationship between the four variables of agricultural non-point source pollution and the per capita agricultural output value in Yichang city,and all of the four inflection points have appeared in the research sequence.Second,from the perspective of pollution sources,the treatment of fertilizer pollution and poultry manure pollution should be the focus of the efforts to control agricultural non-point source pollution in Yichang city.And relevant suggestions are put forward on this basis.
