选取化肥施用强度、农药施用强度、地膜施用强度以及畜禽粪便排泄密度作为黑龙江省农业面源污染的评测指标,对人均农业总产值与农业面源污染的环境库兹涅茨曲线(EKC)进行关系验证。通过研究分析得出以下结论:黑龙江省农业面源污染来源中,化肥、农药、地膜和畜禽粪便均与人均农业总产值之间存在EKC关系,且形状上主要表现为三种形式:农药施用强度与人均农业总产值呈倒“U”型;化肥施用强度和畜禽粪便排泄密度与人均农业总产值呈“N”型;地膜施用强度与人均农业总产值呈倒“N”型,并在此基础上针对黑龙江省面源污染治理提出相关对策建议。
The chemical fertilizer application intensity, pesticide application intensity, plastic film application intensity and excretion density of livestock and poultry manure were selected as the evaluation index of agricultural non-point source pollution in Heilongjiang Province, and the environmental Kuznets Curve (EKC) of per capita agricultural output value and agricultural non-point source pollution Relationship verification. Through the research and analysis, the following conclusions are drawn: Among all the sources of agricultural non-point source pollution in Heilongjiang Province, there are EKC relationships between chemical fertilizer, pesticide, plastic film, livestock and poultry manure and per capita agricultural output, and the three main forms are shown in the shape: pesticide application The strength and output value of per capita agricultural output were inverted “U” type; the intensity of fertilizer application and excretion density of livestock and poultry excrement and the per capita agricultural output value were “N”; the intensity of plastic film application and total agricultural output value per capita were “N” "Type, and on this basis, put forward relevant countermeasures and suggestions for non-point source pollution control in Heilongjiang Province.
