Firstly, we can gain the estimated values of population density adaptive to different kinds of regions. Secondly, we can integrate effectively population data with other data including natural resources, environment, society and economy, build I km GRIDs of natural resources reserves per person, population density and other economic and environmental data, which are necessary to the national management and macro adjustment and control of natural resources and dynamic monitoring of population. In order to establish population information system serving national decision-making, three steps ought to be followed: 1) establishing complete geographical spatial data foundation infrastructure including the establishment of electric map of residence with high resolution using topographical map with large scale and high resolution satellite remote sensing data, the determination of attribute information of housing and office buildings, and creating complete set of attribute database and rapid data updating; 2) establishing complete census systems including improving the transformation efficiency from census data to digital database and strengthening the link of census database and geographical spatial database, meanwhile, the government should attach great importance to the establishment and integration of population migration database; 3) considering there is no GIS software specially serving the analysis and management of population data, a practical approach is to add special modules to present software system, which works as a bridge actualizing the digitization and spatialization of population geography research., 2002, 卷号: 12, 期号: 2, 页码: 114-119 作者:  Deng Xiang-zheng 收藏  |  浏览/下载：273/81  |  提交时间：2011/06/10 spatialization models  population models  LUCC dataset  population spatialization  Deqing County   spatializationmodelofpopulationbasedondatasetoflanduseandlandcoverchangeinchina 期刊论文 chinesegeographicalscience, 2002, 卷号: 012, 期号: 002, 页码: 114 作者:  Deng Xiangzheng;  Zhuang Dafang;  Liu Mingliang 收藏  |  浏览/下载：0/0  |  提交时间：2020/03/23
