中文摘要:
      针对无资料地区水文模拟精度不高的问题,以长江上游李庄、朱沱、寸滩、宜昌四个子流域为例,假定其中一个流域无实测资料,其余流域为参证流域,分别选择TOPMODEL模型和新安江模型,以多目标算法MOCSCDE进行模型参数率定后,移用于无资料流域,开展水文模拟研究工作与结果分析。结果表明,TOPMODEL模型径流模拟结果与实际具有更高的拟合度,更适用于无资料情况下的流域水文模拟,为TOPMODEL模型在无资料地区的应用提供一定依据。
英文摘要:
      In order to solve the problem of low accuracy of ungauged basin forecasting, the TOPMODEL model and parameter migration method were proposed. Four sub basins of the upper reaches of the Yangtze River were selected as cases, namely Lizhuang, Zhutuo, Cuntan, and Yichang. Assuming that there is no measured data in one of the basins, the rest of the basins were reference watersheds. Multi objective algorithm MOCSCDE was used to calibrate parameters of TOPMODEL model and Xin’anjiang model respectively. And then they were used to simulate the streamflow in the other ungauged basins. The results show that the TOPMODEL model is better than Xin’anjiang model for hydrological simulation in ungauged basins, which provides basis for application of TOPMODEL model in ungauged basins.
