摘要
以能量力学原理作指导,地理信息系统技术作支持,通过对土壤侵蚀影响因子的综合作用过程与机理分析,构建土壤水蚀预报的能量力学模型,并在水蚀区通过典型小区和小流域试验予以完善。此研究对土壤侵蚀预报、水土保持与土地利用规划、生态恢复与重建等重大课题均有重要理论与实践意义,并能推动地理学的定量化、信息化与现代化进程。
An energy exchange model for soil erosion prediction has been developed around soil synthesis functions and soil erosion process factors. Model development was based on energy exchange principles and geographical information system(GIS) applications. This research is of theoretical and applied significance to soil erosion prediction, soil and water conservation, soil management, soil biodiversity management and the advancement of geographical principles.
