摘要
运用GIS软件与地理统计学的相关软件,以DEM数据、坡度数据、河网数据、交通网数据、NDVI植被指数数据为基础数据,分析各要素对人口密度分布的影响并采用多元回归模型,模拟了辽宁省人口密度空间分布。模拟结果表明:辽宁省人口密度空间分布主要受高程、河流、交通道路的影响,其中河流与交通道路对人口密度空间分布的影响权重较大。
This paper simulated the spatial distribution of population density in province by using some factors which influenced the population density through multi - regression analysis model. The DEM data, slope image, river network data, transport network data and NDVI image in research area were the basic data. GIS software and other geographic statistical softwares were also needed in the simulation research. The simulation results showed that:the spatial distributions of population density in Liaoning province were influenced mainly by elevation, river networks and transport networks. Among all weight factors, the impact weight of river networks and transport networks were greater than others.
