【摘要】 利用地理信息系统(GIS)提供的空间数据管理操作和空间分析功能,以广东省1998年、1999年水质状况为例,建立了河流水污染空间信息系统,以地区(市)为单位,利用统计方法建立了水质状况与社会经济发展指标的定量关系,并进行了二者的空间关系分析。结果表明,无论从统计关系还是空间分布上,水质状况与单位面积人口数目、人均工业总产值、单位面积农业产值之间都存在较为密切的关系。通过比较,本文指出了广东省水体重污染区人口密度,工、农业总产值的范围与分布,为分析河流水污染及其影响因素和变化规律提供了一种新的尝试。更多还原

【Abstract】 This paper establishes a river pollution information system by using 1998 and 1999’s data of river water qality of Guangdong in a unit of city by GIS. , and provides a quantitative relationship between water quality and social and economic index,and analyses their spatial relationship .The results show that river pollution has a close relationship with industry productive value per person, agriculture productive value per area and the number of people per km2 from the statistic relationship and spatial distributon . This paper points out the range and distribution of population density,industry productive value and agriculture productive value of the river pollution area in Guangdong Province,makes a new attempt to analyse river pollution,its affecting factorsand of trend.更多还原
