祖厉河流域侵蚀地貌的数理分析

Mathematical Analysis on Eroded Geomorphology of Zuli River Basin

以黄河上游水土流失严重的祖厉河流域为研究区域 ,采用R .E .Horton A .N .Strahler水道序列划分原则 ,运用数理统计的方法对该流域的侵蚀地貌进行了定量分析。通过对采集到的大量地貌特征信息值的分析 ,建立了数学模型 ,分析出该流域侵蚀沟壑的系列格局 ,由此揭示了流域地貌序列及其与侵蚀间的相关性 。

The paper makes quantitative analysis on eroded geomorphology of the basin by taking Zuli River basin located on the upstream of the Yellow River where soil and water are severely lost as a study region, using the dividing principle of R. E. Horton-A. N. Strahler water course sequence and using the method of mathematical statistics. It establishes a mathematical model, analyzes a series of pattern of eroded gullies in the basin, reveals the basin geomorphologic sequence and the correlation with erosion and provides a basis for grading small watersheds located in the same type of the region and working out a general plan of soil and water conservation management of the basin through analysis on the collected data.
