摘要

建立了小型水库及淤地坝泥沙淤积体的概化模型．结合水库及淤地坝泥沙观测数据，采用以小型水库的特性征曲线为基础的泥沙淤积量测算方法，对好水川流域小型水库及淤地坝淤积量进行了估算．运用泥沙淤积体规则概化的测算方法对估算结果进行验证，并推求区域侵蚀模数．该方法计算简单，结论可靠，可为进一步研究该流域的水沙规律提供理论依据，并为宁夏南部山区的淤地坝淤积量估算提出一种简便的算法．

Abstract

On the basis of established the generalized model

in accordance with the observed data from the reservoirs and silt dams

the sediment volume of small reservoirs and silt dams in Haoshui watershed was estimated using the small reservoir characteristic curve of silt accumulation. The method of generalized deposition was ap-plied to verify the estimated results and to further calculate regional erosion modulus. This approach was simple and the results were proven reliable. This proposed simple sediment estimation algorithm could pro-vide theoretical basis for further research regarding water and sediment in South Ningxia mountainous area.
