摘要

以陕北黄土高原为实验样区，考虑到流向的计算方法会对计算地形湿度指数产生影响，因而采用单流向算法和多流向算法计算得到地形湿度指数，将地形湿度指数和实测土壤水分数据进行叠加，据此分析土壤水分与地形湿度指数的相关性。同时对比分析单流向算法和多流向算法计算得到的地形湿度指数质量的优劣，提出了利用地形湿度指数模拟土壤水分的最佳流向算法。

Abstract

By taking the Northern Shaanxi Loess Plateau as a study area

the topographic wetness index is calculated by using the single flow direction algorithm and multiple flow direction algorithm. In calculation，it is considered that the flow direction algorithm will have a significant impact on the result of topographic wetness index. The correlation of soil moisture and the topographic wetness index are analyzed based on the data which consist of sampled soil moisture data and topographic wetness index data. The quality of topo-graphic wetness index data calculated by using the single flow direction algorithm and multiple flow direction algorithm are then compared. The best flow direction algorithm to soil moisture simulation is put forward.
