畜禽养殖引发了严重的环境污染问题。文中运用等标污染负荷评价方法和土壤表观养分平衡理论,分别测算了1990-2011年22年间我国畜禽养殖对水体和农田土壤的污染程度与特征,并基于EKC模型分析了畜禽污染与经济增长之间的关系。研究表明:我国畜禽养殖造成的水体和土壤污染已较为严峻,且污染程度均与人均GDP之间存在倒“U”型曲线关系,且已跨过曲线拐点。总体而言,虽然我国畜禽养殖污染随着经济增长已呈现出缓和趋势,但形势仍然严峻。
Livestock and poultry breeding caused serious environmental pollution problems. In this paper, using the method of equal standard pollution load assessment and soil apparent nutrient balance theory, the pollution degree and characteristics of livestock and poultry farms in our country from 1990 to 2011 were estimated respectively. Based on EKC model, The relationship between economic growth. The research shows that the pollution of water body and soil caused by livestock and poultry breeding in our country has been more serious, and the pollution degree has the relation of “U” curve with GDP per capita and has crossed the inflection point of the curve. In general, although the pollution of livestock and poultry breeding in our country has shown a tendency of relaxation with the economic growth, the situation is still grim.
