Research on the Function Transfer and Driving Force of Production-living-ecology Space in Tianshui City
Based on the land use data of Tianshui City in recent four periods,the spatial change characteristics and driving factors are analyzed by using GIS(geographic information system),land use transfer matrix,land use dynamic attitude,comprehensive index of land use degree and other indicators and research methods.The results show that the production space in Tianshui city is reduced,and the living and ecological space is expanded.The comprehensive transfer area of agricultural production land is the largest.The dynamic change of industrial and mining production land is the most obvious.The overall pattern of land use in all districts and counties remains unchanged;Human factors,such as planning and social policy,population size and distribution,and natural factors,such as elevation gradient,hydrometeorology and resource distribution,have significant effects on spatial pattern and change direction.
