【摘要】：基于资源环境约束理论,构建农业发展的水环境约束模型,对长江流域农业发展中的水环境约束强度进行测度,并采用Bootstrap回归模型对水环境约束强度的影响因素进行了实证分析。结果表明:长江流域农业发展受到水资源短缺和水环境恶化的双重约束;农业发展中的水环境约束强度远远超过水资源约束强度,且由各地区综合得出的流域水环境约束强度大于由简单数据加总测算出的流域水环境约束强度,反映出长江流域缺乏完善的水环境统一管理机制;产业结构和工业废水排放量能够显著增强水环境约束强度,水环境治理力度则具有显著的抑制效果。
[Abstract]:Based on the theory of resource and environment constraint, the water environment constraint model of agricultural development is constructed, and the intensity of water environment constraint in agricultural development of Yangtze River basin is measured. The Bootstrap regression model is used to analyze the influencing factors of the water environment constraint intensity. The results show that the agricultural development in the Yangtze River basin is constrained by the shortage of water resources and the deterioration of the water environment. The intensity of water environment constraint in agricultural development is far greater than that of water resource constraint, and the water environment constraint intensity obtained from each region is greater than that of basin water environment constraint calculated by adding simple data. The results show that there is a lack of perfect water environment unified management mechanism in the Yangtze River basin, and the industrial structure and the discharge of industrial wastewater can significantly enhance the restraint intensity of water environment, and the water environment treatment has remarkable restraining effect.
