基于GIS的北京地区未来10年土壤水力侵蚀演化趋势探讨
A Study on the Soil Hydra-Erosion Trend in Coming 10 years in Beijing Area based on GIS
【摘要】 本文是基于永定河上游北京典型段的土壤水力侵蚀深度、降雨强度、地表径流深度、土层有效厚度、土粒平均粒径、植被覆盖度等数据图层 ,利用 GIS、SPSS软件包 ,通过建立水力侵蚀遥感信息模型 ,制作了北京地区土壤水力侵蚀深度图和抗侵蚀年限图 ,依据将近论古的原则及作者的北京地区未来 1 0年环境演化趋势预测结果 ,探讨了未来 1 0年水力侵蚀演化趋势。这可以为该地区未来土地利用和泥石流分布规律研究提供理论指导
【Abstract】 Based on the multiple data layers for mapping such as the depth of soil hydra-erosion, the intensity of precipitation, the depth of surface runoff, the effective depth of soil layer, the average diameter of soil particle, the cover degree of vegetation in typical section of upper Yongding river in Beijing area, this article constructs a model of remote sensing information of soil hydra-erosion with GIS and SPSS software. Based on above data and model, this article works out two maps of Beijing area, one is the depth of soil hydra-erosion, and another is the life span of soil anti-erosion. According to the principle of interpreting the old things from the present and the result of the prediction on the trend of environmental change in the coming 10 years in Beijing area,the article 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.
