文章摘要：基于第六次乡镇级人口普查数据,利用GIS技术展示陕西省人口信息的空间分异格局,通过计算Moran’s I指数、信息熵、分异指数、隔离指数等空间自相关和空间分异指标,结合地貌、资源、产业等地域特征,得出陕西省人口数量、属性及不同社会群体的空间分异特征,探讨其内在机理并提出政策建议。

Abstr：The population data of Shaanxi Province was extracted from the Township Census Data of China in 2010 pressed by the National Bureau of Statistics in Dec. 2012. The Administrative map of Shaanxi Province in township level was extracted from the sharing plafform（） of the earth system science data. The population information spatial database of Shaanxi Province was established by using ArcGIS 10.0 software based on the above data. The spatial trend surface of the population number, population gender ratio, family size, aged people, children, working age population and the foreign population of Shaanxi Province were drawled by the lo- cal interpolation based on the method of inverse distance weighted. The mechanism of population spatial differen- tiation was studied by using Moran＇s I index, information entropy, differentiation index, separation index, et al., and according to the characteristics of topographic features, resources and industries in different region, the fol- lowing conclusions were got： There appears significant positive correlation of population spatial differentiation in the whole province. The most dense population is in the Guanzhong Area （Middle Shaanxi）, followed is in the Southern Shaanxi Area, and less in Northern Shaanxi Area. The gender ratio differentiation of the permanent resi- dent population was related with the industry structure and family gender preference. And the family size is small- er in the cities than in the rural areas, by contraries, family size of Southem Shaanxi Area and Northern Shaanxi Area is smaller than in Guanzhong Area （Middle Shaanxi）. Working-age-people are clustered in township areas in Guanzhong Area, while the children and the elderly were left
