Study on Environmental Impact Evaluation of Different Corn Planting Patterns -Based on LCA
摘要
Abstract
Using the method of life cycle assessment ( LCA ) to analysis pollutant emission inventory of different corn planting patterns in the central area of Jilin province , we carry out the life cycle environmental impact assessment analy-sis.The results shows that comparing the various types of environmental load generated in the process of corn planting pattern , the effects of water toxicity and eutrophication have the largest contribution to environmental impact evaluation result .In the farming system , heavy use of fertilizers and pesticides cause the ammonia volatilization then trigger the en-vironmental acidification .Volatilization of ammonia and nitrate leaching is the main reason of eutrophication .Excessive use of pesticides and then residues in the air , water and soil , is an important factor causing human and ecological toxici-ty.关键词
