基于遥感影像的土地利用类型动态变化监测——以达拉特旗研究区为例

Monitioring the Dynamic Change of Land Use Types Based on Remote Sensing——Take the Dalate Banner as a Case

文章利用RS和GIS的空间分析技术,以TM遥感影像为主要信息源,通过目视解译的方法提取研究区土地利用动态变化数据,结合现地调查进行区域土地利用动态变化分析。研究结果表明:研究区不同土地利用类型之间转换明显,其中,以耕地、草地面积减少,林地、灌木林地、居民地和工矿用地增加为主。土地利用类型变化主要受经济因素影响,国家投入增加和地方经济的发展是土地利用变换的主要原因。

Using RS and GIS spatial analysis technology, taking TM remote sensing image as the main source of information, extracting the data on the dynamic through change of land use in the study area visual interpretation method ,and with doing on-the-spot reconnaissance,we analyzed the regional land use dynamic change .The results show that the conversion between different land use types in the study area mainly reflected in the reduction of cultivated land and grassland,and the increasement of forest land, shrub land, residents land, industrial and mining land . Land use type change was mainly affected by economic factors, the increasement of national investment and the development of local economy is a major cause of land use transformation.
