汤旺河流域输沙量特征分析

Analysis of Sand Transportation Characteristics in Tangwang River Basin

以河流悬疑质泥沙为研究对象,介绍了河流泥沙对一些行业的影响及研究河流泥沙变化规律特征的意义。通过对汤旺河流域主要控制水文站历年实测径流、泥沙资料的统计分析,论述了河流泥沙的主要来源,输沙量的年内分配和年际变化,径流量和输沙量的关系以及流域泥沙的主要成因和泥沙防治措施。为了解流域的泥沙变化规律特征,合理地开发利用其水土资源提供依据。

Taking the river suspended sediment as the researched objective, the impact of river sediment on some sectors and the significance of the river sediment changing law characteristics are introduced. The main sources of river sediment, annum distribution and interannual variations of sand transportation, relations between runoff and sand transportation, and major genesis in the river basin and prevention and control measures against silt are expounded in the study through analyzing the runoff and sediment data measured over the years in major controlling hydrologic stations of the Tangwang River. The study provides the basis for understanding the changing law characteristics of sediment and developing and using the soil and water resources reasonably.
