福建省居民点分布与环境关系的定量研究

Quantitative analysis of the relationship between residential area density and environmental factors in Fujian

居民点分布经常作为人口统计数据空间化的指示因子.文章以2000年第5次全国人口普查数据为基础,计算出的福建各市县平均人口密度与居民点密度有很大的相关性,并基于这种考虑,利用GIS技术定量地分析福建居民点分布与海拔高度、土地利用、道路网、河网、与海岸线距离的关系,认为这些客观存在的关系是进行人口统计数据空间化的基础.

The residential area is an important indicator to the distribution of population. In Fujian Province, correlation ratios of population density and density of city and town residential areas, township residential areas and village residential areas reach 0.679, 0.829 and 0.831 respectively according to the 5th national population census data of 2000. Based on GIS, this paper analyses the relationship between residential areas and environmental factors including elevation, land use, road system, river system and coastline.It is opined that the relationships lay a foundation for the specialization of population census data in spatial areas.
