摘要
新疆的水文气象资料的数量和范围都较小，在对其径流模拟中，首先要解决∶⒈径流的形成机制如何？⒉如何模拟融雪径流？⒊模型输入的时空分布估计。通过大量的资料分析与流域实地调查，笔者认为，新疆山区具有湿润半湿润地区的产流特征和干旱半干旱地区的气候特征。使用温度指标的融雪模型能较好地适应现时的水文气象观测条件。需要搜集与径流形成有关的各种直接或间接的资料，包括人们的感性认识，分析它们的内在联系与关系，以解决水文气象资料缺乏的困难，从而使径流模拟工作能够进行。在本文中，给出了面积分别为１９０５８ｋｍ２和１６３０ｋｍ２的两个流域模拟实例。
There are no sufficient hydrological data in Xinjiang.In the runoff simulation,these questions must be resolved:(1).how the runoff formed?(2).how to simulate the snow melt runoff ;(3).evaluation of time and space distribution input in the model. The mountain areas in Xinjiang have the runoff characteristics of humid and semi humid region.The snowmelt model using temperature index and the climatic characteristics of arid and semi arid region. The snowmelt model using temperature index method fairly comfort with the present hydrologic meteorological routineobservation condition.Only when the all kinds of existing materials are fully used,can reduce the difficulties brought by the lack of materials,then the flow simulation works can be carried out.It is our result after investigated watershed and analsysed some data of Xinjiang.Two examples of runoff simulations of areas of 19058 km 2 and 1630 km 2 are provided in the paper.Xinjiang Stream Runoff Simulation.
