GIS支持下的上海畜禽业污染研究

对上海畜禽业污染信息系统的建立作了有益的探讨。集约化畜禽养殖中污染负荷的空间分布规律研究结果表明，由此所产生的畜禽粪尿达 301.2万 t，单位耕地面积粪尿量表现为近郊 >中郊 >远郊，近郊以生猪场的污染贡献率最高，中郊以生猪和奶牛场、远郊以奶牛场的污染贡献率最高。为减少畜禽业对黄浦江、苏州河水质以及城区环境的威胁，需搬迁畜禽场253个。

Research of Livestock and Poultry Pollution in Shanghai Based on GIS

Establishment of information system for livestock and poultry pollution is evaluated beneficially in this paper. Research of area distribution rules of intensive animal husbandry pollution load indicated that odor and fecal totaled for 3012 thousand tons. Amount of odor and fecal per hectare field in outskirts of the city was more than that either in the middle suburb or in the exurb. The pollution contribution ratio of the hoggery was the highest in the outskirts and, hoggery and cattle farms in the middle suburb and cattle farms in the exurb. It is suggested that in order to reduce intimidation to the Huangpu River, Suzhou creek and city from livestock and poultry, as many as 253 livestock and poultry farms might be removed.
