一类新的变比例尺地图投影——组合投影研究

A New Kind of Variable scale Map Projection Research on Composite Projection

以常用地图投影为基础，通过组合投影方法，得到一类新的变比例尺地图投影。该研究开拓了常用地图投影的功能和应用范围，获得了系统的理论结果和应用实例。

Variable scale map projection is a recent development as a field of research on map projection and has been widely applied. The paper studies and puts forward the theory and methods of composite projection, which is based on map projection in common use. A new kind of variable scale projection is obtained. This method opens up new function and application range for common map projections. Systematical results and applications have been obtained.
