根据国家“九五”重点科技攻关项目“冰雪水资源和出山口径流量变化及趋势预测研究”专题( 96- 91 2 - 0 1 - 0 2 )的部分研究内容 ,运用改进后的融雪径流模型 ( SRM) ,通过天山雪盖的卫星遥感监测和流域模型参数的研究 ,实现了对玛纳斯河肯斯瓦特水文站春季逐日流量的数值模拟 ,结果表明 ,模拟的确定系数可达 0 .89,模拟积差为 5.1 ,满足应用精度 ,可进一步推广应用 According to part of the research contents of “955” key scientific and technological project “Prediction of changes in flow of ice and snow and outlet flow and trends” (96-9120-0100), the improved snowmelt runoff model ( SRM), the satellite remote sensing monitoring of Tianshan snow cover and the study of watershed model parameters were carried out to simulate the daily spring flow of Manasi river hydrological station. The results show that the determination coefficient of simulation can reach 0 .89, The simulation product difference is 5.1, which meets the application precision and can be further popularized and applied
