【摘要】：数字地形分析和流域水文学是地理学领域的重点研究内容,地形要素对流域内地表水循环的产流、汇流等过程以及水资源的时空动态分布具有重要影响。随着遥感与地理信息系统技术的不断发展,地形分析在流域水文建模中的应用得以深化和扩展。该文旨在对水文建模中地形分析的应用进展与趋势进行梳理和分析,从流域水文建模的基本原理和任务出发,回顾了水文模型的分类系统、演化进程以及地形分析在水文建模中的应用情况。综述显示,随着水文模型在驱动机理和响应尺度上的发展,地形分析在其中发挥了越来越关键的作用,尤其在支撑水文过程、增强系统耦合和细化响应尺度等方面贡献明显。同时,流域水文建模的现实需求也促进了地形分析在拓展模型、丰富理论和改进算法等方面的发展与完善。
[Abstract]:Digital topographic analysis and watershed hydrology are the key research contents in the field of geography. Topographic factors have important influence on the processes of surface water circulation and the temporal and spatial distribution of water resources. With the development of remote sensing and GIS technology, the application of terrain analysis in watershed hydrological modeling has been deepened and expanded. The purpose of this paper is to sort out and analyze the application and trend of topographic analysis in hydrological modeling, and to review the classification system of hydrological models based on the basic principles and tasks of watershed hydrological modeling. Evolution process and application of terrain analysis in hydrological modeling. It is shown that with the development of hydrological model in driving mechanism and response scale, terrain analysis plays a more and more important role in it, especially in supporting hydrological process, enhancing system coupling and refining response scale. At the same time, the realistic demand of watershed hydrological modeling also promotes the development and perfection of terrain analysis in expanding the model, enriching the theory and improving the algorithm.
