利用浙江省67个县市的农业经济截面数据,以环境负荷量为因变量,以肉产量和耕地面积为自变量构建模型,对家畜养殖生产的环境效应进行研究。结果表明,2013年绍兴市区、衢州市区、龙游县和江山县的环境负荷量超过警戒值,金华市区、德清县和淳安县的环境负荷量超过适宜值;家畜养殖生产存在着环境负效应,并受到耕地资源的约束,其环境负荷量与肉产量正相关,与耕地面积负相关。
Using the agricultural economic cross-section data of 67 counties throughout Zhejiang province, the thesis builds a model in which 5 kinds of environmental capacity are regarded as the dependent variables while meat production and agricultural acreage as the independent variables, in order to study the environmental effect from livestock farming production. The results indicate that environmental capacity of Shaoxing city, Quzhou city, Longyou county and Jiangshan county were all beyond the corresponding alert values in 2013, Jinhua city, Deqing county and Chunan county were all beyond the corresponding good values; there is environment negative effect existing in livestock farming production which subject to the cultivated land resources,that is,a positive correlation between environmental capacity and meat production is existed with a negative correlation between environmental capacity and agricultural acreage.
