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。
The quantity and scope of hydrological meteorological data in Xinjiang are relatively small. In the simulation of its runoff, we must first solve: (1) How is the formation mechanism of runoff? ⒉ how to simulate snowmelt runoff?时 Spatio-temporal distribution estimation of model inputs. Through a large amount of data analysis and field investigation, I believe that Xinjiang mountainous area has the characteristics of runoff in humid and semi-humid areas and the climate characteristics of arid and semi-arid areas. The snowmelt model using temperature indicators can better adapt to the current hydro-meteorological observation conditions. It is necessary to collect various kinds of direct or indirect information related to the formation of runoff, including people’s perceptual knowledge, analyze their internal relations and relationships so as to solve the problems of lack of hydrological and meteorological data so that runoff simulation can be carried out. In this paper, two watershed simulation examples with area of 19058km2 and 1630km2 are given respectively.
