地理因子与空间人口分布的相关性研究

An Discussion on Correlation of Geographical Parameter with Spatial Population Distribution

通过建立包括居民地、公路、铁路、水系、高程带、坡度带、坡向带、土地覆盖等要素内容的地理因子库 ,以及包括国民经济和社会发展主要指标的经济因子库 ,提取在一定区域内与人口分布密切相关的因子组成 ,并以其归一化相关系数作为定量分析的权重系数。本文提出的是实现人口在空间单元内遵循人口分布规律的空间化分布的一种尝试。

A geographical parameter database,including number of inhabitant sites,highway,railway,water system density,altitude,slope,slope aspect zone,land cover and so on,has been established.At the same time,a economical parameter database,including the main variables of national economy and social development,has been established as well.The factors which have strong correlation with population distribution in certain region have been extracted. Their standardized weight coefficients have been made as weight coefficients of population distribution in spatial cell.Both geographical parameter database and unit population database are able to offer sufficient conditions for quantitative analysis.They will play an important role in research fields of data mining (DM),decision making support systems (DSS),and regional sustainable development.
