Glacier dynamic model is very important to understand the process of glacier change and forecast its future response to climate change. Some parameters of glacier dynamic model have been manually generated, which is time-consuming. In this research, a new process, which couples ESRI Arc Micro Language (AML) and Visual Basic for Applications (VBA), is process to semi-auto extract the parameters, such as elevation, slope, and band area of each node along the mainstream of a glacier. As examples, the glaciers in Yarkand River basin are introduced, by using the vector map of glaciers, glacier mainstream lines, Digital Elevation Model (DEM). The nodes in the mainstream are auto-extracted at first, then the elevation of each node is auto-extracted, and the band area between two nodes is automatically calculated on the basis of "zonalstats". At last, the results are integrated in one file for the model input. This process greatly enhances the efficiency of preparing the parameters of dynamic glacier model, and will be widely applied.
