摘　　要：该文提出了一种由WGS-84坐标系大地坐标至1980西安坐标系高斯直角平面坐标转换的流程,并实现了关键的算法,包括高斯-克吕格投影的正算及"布尔莎-沃尔夫"模型七参数的解算。通过实验数据的验算及实际应用,证明该文提出的方法是可行的。Abstract：In this paper, a conversion process from WGS -84 geodetic coordinate system to Xi＇an 1980 Gauss rectangular plane coordinate system has been put forward. It realizes the key algorithm, including the cal- culation of Gauss - Krueger projection and the calculation of 7 - parameter transformation. Through the calculation of experimental data and practical application, it is showed that the proposed method is feasible.
