摘要
河流泥沙是反映流域水土流失严重程度和河川径流特性的重要指标,是合理开发利用地表水资源,建设水利设施必须考虑的一个重要指标。河流泥沙不仅关系河流本身的发展演变,也反映了流域环境特性及人类活动的影响。木垒河是一条多沙河流,泥沙问题不太引起关注,研究也相对缺乏。本文就木垒河泥沙资料分析,对木垒河泥沙的主要来源、分部、年内变化等时空演变进行了初步分析,为木垒河流域水资源合理开发提供一定的参考。
The sediment is an important indicator of the severity of soil erosion and river basin runoff charac-teristics,and of rational development and utilization of surface water;the construction of water conservancy fa-cilities must be considered.Not only the relationship between the evolution of river sediment in the river itself , but also reflects the impact of watershed environmental characteristics and human activities.Molei River is a river containing more sand,silt problem is less cause for concern,but also lack the relative research.In this paper,based on Molei river sediment data analysis,the main source of river sediment,divisions,changes during the year temporal evolution,a preliminary analysis has carried out;It provides a reference for the rational de-velopment of Molei River Basin Water Resources.
