基于RS和GIS的巴仁哲里木地区土地利用/覆盖变化研究

Study on Land Use/Cover Change(LUCC) in the Region of Barenzhelimu Based on RS and GIS Technology

基于遥感(RS)和地理信息系统(GIS)相结合的方法,分别提取了1999和2009年内蒙古巴仁哲里木地区土地利用/覆盖变化(LUCC)的类型和数量,并通过迭加运算和统计获得土地利用/覆盖变化转移矩阵,对1999和2009年的土地利用/覆盖变化结果、特点及驱动力进行了研究与分析。结果显示,草地大面积减少,耕地与沙地面积增加较多,同时河漫滩沙地、居民地、林地、裸地、建筑用地和其他用地类型面积均有不同程度的增长;土地利用/覆盖变化源于自然因素和人文因素的共同驱动。

Based on the integrated techniques of Remote Sensing（RS） and Geographic Information System（GIS）,this paper extracted the types and quantities of land use/cover change（LUCC） of the region of Barenzhelimu in the Nei Mongol Autonomous Region in 1999 and 2009 separately,and got the conversion matrix model through superpose operations and statistics,then studied and analyzed the findings,features and drives of land use/cover change in 1999 and 2009.The results are as follows：from 1999 to 2009,the areas of grassland decreased largely,but the farming land and desert increased much,and the areas of the flood plain desert,the settlement place,the forest land,the bare land,the other building land and the land of other using types increased differently;land use/cover change was derived by the natural factor and anthropogenic factor.
