- Abstract:
- Soil loss evaluation model and GIS integration is the most focusing problem in current research and application of GIS.In this study,based on the component object model technology and ArcGIS Engine,an extended GIS model was developed based on the conceptual models of RUSLE and Soil Loss Index model.Binary dynamic link library(DLL) was built to implement special functions with the language of Visual Basic.This module mainly including soil erosion calculation sub-component,soil loss evaluation of watershed scale sub-component,soil loss evaluation of small watershed scale sub-component,and soil loss evaluation of slope scale sub-component.It is capable of simplifying computational logic of the soil loss evaluation,improving the work efficiency.And it is a model which has good extendibility,flexibility,and maneuverability.The results showed that it is a practical and effective method that to explore an extended module based on ArcGIS Engine,represent by the manifestation of binary dynamic link library.Soil Loss Index would be used widely in the correlation research of landuse and soil loss evaluation.
