# 基于ArcGIS Model Builder的地形指数提取方法及实践研究The Study on Terrain Index Extraction Method and Practice Based on ArcGIS Model Builder

River terrain index TOPMODEL hydrological model has been applied to Land surface model (Land surface Models, LSMs), to improve Land surface of hydrological process simulation model. The core of TOPMODEL is terrain index (ln(α/tanβ)). And it is an important index on the hydrologic analysis. Therefore, effective extracting terrain index information is very important. In this paper, the huaihe river basin as a case area, the terrain index extraction process model is build, using the ArcGIS9 Model Builder tools. This model is based on a single flow algorithm for calculating process. Model has higher versatility, because of fully considering the effectiveness of the parameters such as the slope and the flow accumulation in the model design process. Using this model can be very simple and quick to get terrain exponential distribution data of terrain index.
