摘要
基于作者对北京地区中全新世以来环境演变研究和未来１０年预测结果，利用ＧＩＳ、ＳＰＳＳ软件包，通过建立水力侵蚀遥感信息模型，制作了北京地区现代土壤水力侵蚀图，依据将近论古的原理，恢复了北京地区小冰期时期和仰韶文化时期的土壤水力侵蚀深度，探讨了未来１０年水力侵蚀演化趋势，这可以为该地区土地利用和泥石流分布规律研究提供理论指导。
Based on the author' s study of environmental evolution and the prediction in the coming 10 years in Beijing area since mid Holocene, this paper forms a model of remote sensing information of soil hydra-erosion with SPSS software and works out the map of soil hydra-erosion of Beijing area in the contemporary time by GIS. According to the principle of reasoning the old things from the present, the article also restores the depth of soil hydra-erosion in the period of Yangshao civilization and Little Ice, as well as discuses the trend of soil hydra-erosion in the coming 10 years. The study may provide a theoretical direction for the research of land use and distribution of mud-rock flow in Beijing area.
