摘　　要：由于种种原因,我国在不同时期各部门采用了不同的坐标系统。随着国民经济的发展,现代工业生产迫切需要统一的坐标系统,以保障国民经济生产的顺利进行。而空间技术的发展,为我们统一坐标系统提供了便利。本文实现了二维七参数坐标转换和二维四参数坐标转换,并在不同区域范围进行实例分析,结果能够满足相关部门的精度要求,在工业生产中具有一定的实用价值。Due to various reasons, different coordinate systems at different times are used by individual organizations. With the development of national economy, modem industrial production urgently needs a unified coordinate system to ensure the smooth progress of national economy. At the same time, the development of space technology makes us conveniently to realize a unified coordinate system. This paper gives two dimensional seven-parameter and four parameter coordinate transformation method. As a case- study, the method is applied in different regions. The results show that the coordinate transformation method can meet the accuracy requirements of the relevant engineering and also has practical value in industrial production.
