摘　　要：以某滑坡群勘测工程为例,对GNSS拟合高程测量联测点选择进行探讨,阐述了拟合高程测量联测水准的必要性,分析了水准联测点对GNSS拟合高程异常模型内、外符合中误差的影响。Taking a survey project of a landslide group as an example,this paper discusses the selection of joint survey points in GNSS fitting elevation survey,expounds the necessity of joint survey points in fitting elevation survey and the minimum number of joint survey points,and analyzes the influence of joint survey points in GNSS fitting elevation model on the error of internal and external conformity of elevation anomaly model.
