基于多源数据与GIS技术的福建省人口数据网格化

Population Data Gridding in Fujian Province Based on Multi-source Data and GIS

基于多源数据融合思想,以福建省第六次人口普查数据为基础,利用GIS技术,将DMSP/OLS、土地利用、DEM、MODIS等多源数据提取其像元值转入同一位置的网格中,消除多源数据位置不匹配难题,运用聚类——多元逐步回归分析构建了人口网格化模型模拟及精度检验,最后进行空间网格化表达。可为有关部门在灾情速判、区域经济发展调控、资源可持续发展等提供数据支持。

Population data gridding based on Multi-source Data Fusion and the sixth census data of Fujian Province,using the technology of GIS,DMSP/OLS,land use,DEM,MODIS and other multi-source data extracted from the pixel value into the same location in the grid,eliminate the multi-source data position does not match the problem of clustering operation--multiple stepwise regression analysis was constructed model simulation and precision test and population grid,spatial grid.For the relevant departments to speed disaster judgment,the development of regional economy regulation,to provide data to support the sustainable development of resources.
