摘　　要：以C^＋＋为开发语言,在.NET开发环境中,调用ArcGIS Engine开发包,设计基于插件技术和GIS坡面土壤侵蚀量估算系统,结合6次人工模拟降雨试验土壤侵蚀数据和三维激光扫描（LiDAR）地形数据,验证该系统估算土壤侵蚀量精度。结果表明,该系统估算坡面土壤侵蚀量具有较高精度,其值介于93.3%-99.5%间,平均估算精度95.8%。计算机模拟系统能较好模拟坡面土壤侵蚀形态,说明此系统估算坡面土壤侵蚀量可行。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.
