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.
