基于地形梯度的矿业城市土地利用格局变化特征分析OA

Taking Jixi City, a typical mining city as an example, this paper quantitatively analyzed the changing characteristics of land use patterns in mining cities by using the methods of terrain location index, distribution index and land use change map under the support of RS and GIS.The results showed that affected by mining activities and urban expansion, land use types had strong differences in different terrain gradients;arable land and construction land had a high frequency of change in low-lying areas, and gradually expanded to high-lying areas;al-ternate transformation of arable land, forest land and grassland occurs frequently in topographic areas.
