基于遥感、GIS的旗县域土地利用变化研究-以内蒙古奈曼旗为例

Research on Land Use Change in County Region by Remote Sensing and GIS —— a Case Study in Naiman in Inner Mongolia

遥感及 GIS技术是土地利用变化研究的重要手段之一。文章选取位于我国北方农牧交错带的内蒙古奈曼旗为研究对象 ,利用研究区 80年代末 TM影像及 2 0 0 0年 TM影像数据 ,对该区十多年的土地利用变化进行了全面分析。结果表明 :随着土地利用强度的不断增加 ,奈曼旗土地利用产生了显著的变化 ,主要体现为水浇地旱地化、草地退化、耕地及草地沙漠化。
