天山北坡地区的产流方式

流域径流模型对河川径流的模拟效果,在很大程度上取决于所采用的产流方式是否与该地区的气候及下垫面条件相适应。本文在分析天山北坡地区的气候及下垫面条件和在该区乌鲁木齐河流域的入渗试验基础上论证了新疆虽属干旱地区,但天山北坡的产流区,其产流机制与湿润及半湿润地区相类似。产流方式以蓄满产流为主。这一结论的正确性已通过对切德克河的径流模拟成果得到证明。

The Mode of Runoff Formation in the Northern Hillslope Area of Tian Shan Mountains

The effect of simulation for a Watershed runoff model to streamflow, in a great degree, depends on whether the mode of runoff formation adoped corresponds to the conditions of climate and ground surface in this area. This paper, based on the analysis of the conditions of climate and ground surface in the northern hillslope area of Tian Shan Mountains and on the infiltration experiment of Wulumuqi River Watershed, demonstrates the mode of runoff formation for this area of runoff formation in the northern hillslope area of Tian Shah Mountains. Although Xinjiang is an arid region, it's mechanism of runoff formation is similar to that of humid regions and semi-humid regions. Hence the mode of runoff formation is goverved by the satisfaction of natural storage. This accuracy of conclusion has been shown by the results of runoff simulated on Qiedeke River.
