北京市土地利用分布与水质响应空间关系研究

摘要

With 16 water quality monitor sections and drinking water sources in Beijing as research object, using 16 water qualityrnmonitor automatism sites data during 2009 to 2010 and Beijing landuse data in 2009, the paper analyses response relationshiprnbetween different buffer areas landuse and transit water quality. The result of research indicates that the agriculture non-pointrnpollution effect on the water quality evidently in the farm land. In large scale regional, increasing the forest area ratio can improvernwater quality. The rural resident which is close to surface water effect on the water quality badly. The industry building land effectrnon water quality in the large scale significantly.%以北京市16个水质监测断面和饮用水源地作为研究对象,利用2009-2010年16个永质监测自动站监测数据与2009年北京市土地利用数据,分析不同缓冲区内土地利用与过境水质之间的响应关系.研究结果表明,耕地产生的农业非点源污染对水质影响明显；在大尺度区域增加林地面积比例有利于改善水质；离水源近的农村居民用地对水质产生负面影响；工业建设用地对水质影响在较大尺度上更为显著.
