Abstract:
In order to analyze the internal characteristics and driving mechanism o f land use change, the spatial and temporal changes o f land use have been comprehensively examined based on the overall pattern of land use, the direction of land use transfer , the degree o f transfer, and the single dynamic degree of land use in the Kuye River Basin in the past 40 years. SPSS soft ware is used to systematically ex plain its driving mechanism. T he results showed that: T he proportions of different land types throughout the basin are grassland> farmland> coal mine land> forest land> sand land> residential land> water area> unused land, respectively; Farmland is lar ely gathered in the middle and southeast of the basin while coal mine land is mainly distributed along the riv er bank; In the research period, as the most dynamic type of land use, coal mine land had greatly increased its area, and its main inflow sources are grassland and farmland, and T he large scale exploitation of coal in this basin has seriously affected the vegetation cover and agricultural production activities in this basin; T he rapid economic development , especially the growth of the secondary and tertiary industries are the most important driving factor leading to obvious changes in the coal mine land and residential land in the basin, H ow ever the changes in farm land, forest land, grassland, and water area are also closely related to them, but the changes are relatively small; Besides, the population also plays a more obvious role in the process of land use change.
