摘　　要：针对多元回归坐标转换方法仅适应于小范围坐标转换的缺陷，提出了基于格网的多元回归坐标转换方法，并应用于徐州市国土资源执法监察，将徐州市沿经线和纬线方向划分为3’×3’的格网，每个格网节点搜索附近的6～8个公共点，建立多元回归模型进行坐标转换。结果表明，该方法的内、外符合精度达到厘米级。A grid coordinate transformation method based on multiple regression model is proposed so as to overcome the shortcoming that general multiple regression model can only apply to small area. The new method is used by law enforcement and supervision of land resource in Xuzhou city. The grid multiple regression model is established by dividing Xuzhou into a grid of 3＇ × 3＇ squares along the direction of longitude and latitude and searching 6-8 common points on each grid node. The results show that both the inner and outer precision of the method are at centimeter level.
