【摘要】 针对资源环境研究领域对空间型社会经济数据的需求,在综合分析我国经济社会的区域差异的基础上,对现有的统计型行政单元主要社会经济发展指标国内生产总值(GDP)进行空间化模拟,建立了统一空间坐标参数、统一数据格式、统一的数据和元数据标准的全国1公里格网水平社会经济空间数据库。利用从卫星遥感数据建立的1995年详尽的1:100,000比例尺土地利用格局分布图,综合分析人类活动形成的土地利用状态与GDP大小的空间互动规律,建立影响经济发展的关键因素评估模型,通过一、二、三产业GDP与土地利用类型的空间关联性,分区建立1995年县级GDP和土地利用格局的空间关联度模型库,实现在1公里格网的社会经济数据的空间定量模拟。更多还原

【Abstract】 The study of resources and environmental sciences require greatly the spatialized data sets of socio-economic data which is always obtained from administrative region like county or province. The authors integratedly analyze the regional differences of China’s economic development first An approach to the spatialization simulation of China’s gross domestic product (GDP) from original county level statistical data to the 1km gridded database with the standard coordinate system, data format and metadata document The data used in the paper is land use spatial database derived from Landsat TM at 1:100,000 scale with 25 classes land use types as well as topographic maps of whole China. The interaction between GDP structure and different land use patterns are analyzed and simulated. Some key indicators are selected to build the model of GDP spatialization simulation. Based on the herarchical regions of economic development level, spatial relation model between GDP and land use pattern is developed to expend the county GDP to the 1km grid.更多还原
