摘　　要：利用三个时相的高分辨率遥感数据为主要信息提取源,对青海省西宁地区基础地质、水文地质、工程地质及地质灾害现状等情况进行遥感调查.经过室内解译和野外调查,初步查明了地形地貌、河流阶地、出露地层、水文地质要素、岩土体分布、地质灾害分布及特征,通过野外验证取得较好的效果.调查结果表明,遥感技术的应用可以使地质调查具有较为充足的地质预见性,指导西宁市地质调查工作,提高调查效率和成果质量,是地质调查的重要手段.In order to exert the role of high resolution satellite data in urban geological survey,the author used three temporal remote sensing images as the main data source of information extraction and investigated basic geology,hydrogeology,engineering geology and geological disaster in Xining urban area.Through indoor interpretation and field investigation,the author ascertained distribution and characteristics of geomorphology、stream terrace、outcropping strata、hydrogeological factors、rock mass and soil mass、geologic disaster.The field verification has achieved good results.The survey results show that the method can improve the application of remote sensing in the foresight of geological survey work,guide the surveying and mapping work,and improve the overall efficiency and quality of the project.Therefore,it is an important means in geological survey.
