【摘要】 本研究以地理信息系统(GIS)为手段,借助GIS空间数据、属性数据管理的优势,构建了京郊地区畜牧生产状况和环境质量状况的数据库,并实现了畜牧生产资料数据库与北京地区土地利用图以及水系图的有机集成。在此基础上,根据北京地区土地肥料利用的实际能力,完成了对京郊地区土壤粪便负荷的分析以及粪便污染风险的警报分级,并使得京郊地区畜禽环境质量信息最终以可视化的形式在计算机上表达出来。研究结果表明,目前北京远郊各区县都存在不同程度的环境威胁性,其中顺义区以及门头沟区的环境威胁比较严重,密云县畜牧环境污染的形势值得关注。更多还原

【Abstract】 By means of geological information system (GIS) with its advantage of administering spatial and attribute data, the database of livestock production and livestock environment quality was built. The map of Beijing land utilization and hydrographic network was accordingly drawn and superposed, and these database and figures were highly integrated. Based on the actual ability of soil utilizing fertilizer in Beijing suburb, the fecal loading state of soil was analyzed and the alarm signal of hazard caused by fecal pollution was classified. The information about livestock environment quality in Beijing suburb was expressed visually in computer. The result showed that all district and county in far suburbs of Beijing were threatened by pollution in varying extent. Among these areas, the threat of fecal to soil in Shunyi district and Mentougou district was comparatively serious. Therefore, more attention on farming environmental pollution to Miyun County should be paid.更多还原
