The soil erosion estimation from individual rain event is the emphasis and difficulty in soil erosion research. This paper, based Plug-in technology and GIS, designed a computer simulation system for hillslope soil erosion witten by C++ computer program under C++.NET and ArcGIS Engine SDK. The soil loss data collected from 6-times continuously simulated rainfall expeiments and 6-times surface terrain data measured by three-dimensional Laser Scanner (LiDAR) were used to validate feasibility of the designed computer systems for estimation hillslope soil erosion. The results showed that the designed computer system based on Plug-in technology and GIS had higher precision for calculating hillslope soil erosion. The estimating soil loss precision of the designed computer system was from 93.3% to 99.5% and the average precision was 95.8%. Moreover, the designed computer system could be better to simulate hillslope erosion patterns. Overall, the the designed computer system for estimating hillslope soil erosion was feasibility.
