摘要
以矿业城市鸡西市为例,在RS和GIS支持下,运用地形位指数、分布指数和土地利用变化图谱等方法,定量分析矿业城市土地利用格局的变化特征。结果表明:受采矿活动和城市扩张的影响,矿业城市土地利用类型在不同地形上的分布具有较强烈的差异性;耕地和建设用地在低地势区域的变化频率较高,且逐渐向高地势区域拓展;在中地势区域多发生耕地、林地和草地的交替转化。
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;alternate transformation of arable land,forest land and grassland occurs frequently in topographic areas.
