摘要
我国将于2017年进行第二次全国污染源普查,其中将包括畜禽养殖污染源,并将建立畜禽养殖管理地理信息系统(GIS),以科学估算环境承载能力,评价畜禽养殖污染对环境的影响,为《畜禽规模养殖污染防治条例》的顺利实施提供数据和技术支撑。详细分析畜禽养殖管理GIS的空间数据源的类型,分为养殖单位信息、规划因子地理信息、专题地理信息、底图矢量地理信息和底图栅格地理信息;然后分析获得这些信息的途径;最后讨论设置空间坐标系的方法,可为第二次污染源普查和畜禽养殖GIS的建设提供借鉴和参考。
The second national census of pollution sources will be carried out in China in 2017, while the livestock pollution source information will be collected and the livestock management geographic information system （GIS） will be established to scientifically estimate the carrying capacity of environment and assess the impact of livestock pollution on the environment, so as to provide technical support for the implementation of ＂Regulations on Prevention and Control of Pollution for Scale Livestock and Poultry Breeding＂. The types of spatial data sources of livestock management GIS were categorized into breeding unit information, geographic information of planning factors, thematic geographic information, geographic information of base map vector, and geographic information of base map aster, and then the ways to collect this information and set up spatial reference systems were analyzed in details to provide reference for second national census of pollution sources and the construction of livestock GIS.
