摘　　要：当前我国对海岛资源的逐步开发、利用日益迫切,海岛测量变得十分重要。本文主要介绍了海岛测量过程中建立2000国家大地坐标系(CGCS2000)控制网的方法,论述了从框架ITRF2000转换到框架ITRF1997的方法和过程,并用象山县旦门山岛为例做了验证,结果表明利用该方法快速建立四等GPS控制网是可行的。The Island surveying becomes very important because of the urgent developing and using the island resource.The method of establishment 2000 national geodetic coordinate system（CGCS2000） control network,during the island exploring,is introduced in this paper,and the transformation process from ITRF2000 to ITRF1997 is presented as well.Those methods are verified by real island surveying project located on Xiangshan country Danmenshan Island of Jiangsu province,and the result shows that the method of rapid establishment of fourth grade GPS control network is feasible.
