达拉特旗土地利用及水土保持措施现状遥感调查与制图

Investigation on Land Use and Water and Soil Conservation Measures by Remote Sensing----Taking Dalate County, Inner Mongolia Autonomous Region for Example

达拉特旗土地利用及水土保持措施现状遥感调查以分辨率为30m的Landsat的TM影像为主要信息源,首先确定典型样区,通过野外调查,确定土地利用和水土保持措施的分类系统和建立解译标志;绘制典型样区草图并进行室内判读;野外校核,提交编绘原图。最后分析该旗土地利用及水土保持措施现状的基本特征和分布规律,发现存在的问题并提出对策。

The investigation on land use and water and soil conservation measures by remote sensing is a subproject supported by the project 'Investigation on water and soil conservation by remote sensing in the drainage basin of the Yellow River, Inner Mogonlia'. This paper discusses the methodology and procedure of the investigation on land use and water and soil conservation measures by using the advanced technology of remote sensing and GIS, according to Landsat TM. Firstly, select the typical plots and establish the classification system and the interpretation signs -, secondly, protract the sketch map of the typical plots and indoor recognition; thirdly, field revision and compile original map; lastly, analyze the basic characters and the distributing rule, find the existent problems and bring forward the countermeasures.
