新疆河流下游为平原河流,天然河道断面不规则,多为宽浅性河床,水量沿程损失较大,研究河道损失规律,对下游生态、水资源有效利用意义重大。通过黄水沟、清水河枯水期河道上、下游断面实测流量资料,采用水文学原理建立线性模型,对两河出山口以下平原区枯水期河道水量沿程损失进行计算分析,分别得到了两条河流在枯水期沿程单位长度损失水量估算模型,计算了枯水期两条河流的水量损失量,可为天山以南山溪性河流枯水期沿程损失量的定量分析提供依据。
The lower reaches of the Xinjiang River are plains rivers. The sections of the natural river are irregular with mostly shallow riverbed. The loss of water along the riverway is large and the law of loss of the riverway is studied. It is of great significance to the effective utilization of downstream ecological and water resources. Based on the measured flow data of the upper and lower sections of the Yellow River ditch and Qingshuihe river in dry season, a linear model was established by hydrology to calculate and analyze the loss of water along the river in the dry season below the outlet of the two rivers. Two rivers were obtained during the dry season The unit loss of water along the length of the unit estimation model to calculate the amount of water loss of two rivers in the dry season can provide a basis for quantitative analysis of the loss along the creek during the dry season of the creek.
