摘要
基于MIKEBASIN平台,将长江流域划分为91个子流域,采用NAM模型来模拟各分区径流过程,再将各分区NAM模型连接成为整体,构建了长江流域水量模型,并完成了模型系统中面雨量计算、参数批量修改、水库调度等关键功能的二次开发。模拟结果表明,模拟径流过程与实测过程基本一致。鉴于部分子流域面积过大,取、排水用户未纳入模型等原因,导致模拟年径流有所偏大,以汉江流域为试点进行了模型细化研究,显著提高了模拟精度,表明长江流域水量模型模拟精度尚有进一步提高的空间。
Based on MikeBasin Platform,the Yangtze River Basin was divided into 91 sub-basins.The runoff process in divided sub-basins were simulated by NAM model,and the sub-basin NAM models were integrated as whole to construct the water volume model of the Yangtze River,and the secondary key function development of areal precipitation computation,batch revision of parameters,reservoir regulation etc.were completed.The simulation result show that the simulated runoff process is basically consistent with measured pro...
