摘　　要：大井坡航空地球物理试验场是在国家高技术研究发展计划项目支持下确定的我国首个航空地球物理(航磁、航重和航电)综合试验场。综合试验场的选址是一项十分重要和困难的工作,因为综合试验场要求同时满足航磁、航重和航空电磁等多种测量系统检验条件。因此,综合试验场选择需要综合考虑以下基本原则:要求试验场及周围人文环境干扰少;地形有一定起伏;地质内容丰富,最好有已知铁矿点(或小型铁矿床);航磁、航重、航电异常明显等。根据这些原则,采取"先选区后选场、区中选场"的方法,在综合分析对比地形、地质和地球物理等资料并实地考察后,在全国范围内筛选出四子王旗试验区,对四子王旗试验区作进一步详细工作后,在试验区东北角大井坡地区确定了大井坡航空地球物理试验场的范围和具体位置。Dajingpo Airborne Geophysical Test Site is the first airborne geophysical（magnetic,gravity and electromagnetic）integrated test site in China,at the sponsor of 863 project.The selection of integrated test site is an important and difficulty work,because it need to consider of all the conditions for the test of magnetic,gravity and electromagnetic systems.Therefore,the selection of integrated test site need to consider the basic principles as follow： the interfere is small in the test site and around;there is diversity in topography;there is affluent in geology,and possess of iron points（or iron deposits） are best;magnetic,gravity and electromagnetic abnormities are obvious.,and so on.According to the basic principles and methods of ＂Select a large region first,and the site wherein ＂,after the synthetical analysis and contrast in topography,geology and geophysical materials and check in field,Siziwangqi Test Site is filtered from all the county,then do more detailed work to Siziwangqi Test Site,Dajingpo Test Site is determined in the Dajingpo area at the NE corner of the Siziwangqi Test Site.
