摘要
利用我国第六次人口普查统计的人口数据,借助GIS软件及其数据处理分析方法,分析珠江流域最新的人口分布特征,并定量统计不同气候和下垫面因素对珠江流域人口分布的影响。结果表明,流域人口密度与多年平均降雨呈现一定的正相关,人口多分布在年平均降雨量大于1500mm的地区;而地形条件和交通条件是珠江流域人口分布的主要控制因素。
Characteristics of population distribution in the Pearl River Basin is firstly analyzed according to the 6th population census of China. And then impacts of climate and land surface conditions on the population distribution are evaluated for the basin. Results shows that there is a positive correlation between rainfall and population density. Population tends to distribute in the region with annual average rainfall larger than 1 500mm. Topography and traffic conditions act as the major controlling factors of population distribution in the Pearl River Basin.
