| 摘 要： | 针对冰雪融水河流的产流与汇流特点,基于SWAT模型能量平衡计算原理,充分考虑地形、辐射、风、下垫面及冻土等因素对融雪的影响,研究了山区冰雪融水河流的日径流,基于遥感数据与地理信息数据得到的积雪信息,以及玛纳斯河流域1980—1995年气象、径流等实测数据,建立了适合山区融雪河流的SWAT分布式流域水文模型,并模拟了玛纳斯河流域出山口处肯斯瓦特水文站的日径流,模拟相对误差为17%、Nash Sutcliffe效率系数为0.73,模拟结果合理可靠,为研究冰雪融水河流的径流模拟提供了有效的途径。

| Abstract: | Focus on the characteristics of runoff yield and flow,considering the influence of terrain,radialization,wind,vegetation distribution and frozen earth on snowmelt,the daily runoff of montane river which is mixed replenishment of ice and snowmelt has been studied based on the theory of conservation of energy with SWAT model.Base on the snow pack information of RS and GIS,and 21 years of the actual metrical data about weather and the runoff from 1980 to 2000 in the Manasi valley,SWAT model for snowmelt river has been established.The daily runoff of Kensiwate hydrological station in the mountain pass of the Manasi watershed was simulated.The results showed that RE of the simulation was 17%,Nash Sutcliffe was 0.73,the simulation was reasonable,and it would supply an effective method for studying the ice and snowmelt rivers in future. |
