农业经济发展和环境污染的联立方程模型构建研究

Construction of simultaneous equation model of agriculturaleconomic development and environmental pollution

我国水资源缺乏,农业经济发展主要受到水资源制约,鉴于此,本次研究将构建农业经济发展与环境污染的联立方程模型,并从水污染的角度探究环境污染对农业经济发展的影响。实验结果表明,农作物单产受到工业废水排放量、化肥用量、废水治理成本的影响;污水灌溉降低农作物产量,致农作物严重受损,如农作物产量的降低、农作物中污染物含量超标、农作物品质下降;随着农业经济发展水平的提高,能有效地降低单位面积内农药、农膜、化肥的增长速度,有利于环境质量的维护。本次研究希望能为农业经济可持续性发展提供参考。

due to the lack of water resources in China,agricultural economic development is mainly restricted by water resources,In view of this,this study will build a simultaneous equation model of agricultural economic development and environmental pollution,and explore the impact of environmental pollution on agricultural economic development from the Perspective of water pollution.The experimental results show that the yield of crops is affected by the discharge of industrial wastewater,the amount of chemical fertilizer and the cost of wastewater treatment;sewage irrigation reduces the yield of crops,causing serious damage to crops,such as the decrease of crop yield,the content of pollutants in crops exceeds the standard,and the quality of crops declines;the improvement of agricultural economic development level can effectively reduce the pesticide and agricultural production per unit area The growth rate of membrane and chemical fertilizer is conducive to the maintenance of environmental quality.It is hoped that this study can provide a reference for the sustainable development of agricultural economy.
