基于RS和GIS的土地利用变化监测

Monitoring of Land Use Change Based on RS and GIS

以北京市朝阳区为例,基于ENVI软件和GIS软件的主要理论和技术方法,对该地区近9年的土地利用状况进行监测。主要介绍了遥感影像的预处理,分类后处理以及利用处理后的数据制作专题图、统计图的具体流程。基于RS和GIS的土地利用变化监测手段将土地利用变化情况表达为图表形式,客观形象地反映了研究区域在研究时间段内的土地利用变化情况,为城市规划用地、道路桥梁建设等提供了基础数据。

Based on the main theory and technical method of ENVI and GIS, the land use situation in Chaoyang District of Beijing in recent 9 years is monitored. This paper introduces remote sensing image preprocessing, classification processing and the process of making thematic maps and cartogram. The monitoring method based on RS and GIS shows the land use change in chart form, which objectively reflects the change of land use and provides the basic data for urban planning and road and bridge construction.
