| 摘 要： | 气候变化和人类活动影响使得部分地区水文系列资料的一致性受到影响,从而使得这些地区逐渐变成缺资料地区或无资料地区,无资料地区水文预测(PUB)问题一直是国际水文的研究热点,而山丘区的无资料小流域PUB更是其中的难点之一。分别选取了资料条件相对丰富的江苏省北部的黑林、南部的横山水库、中田舍等3个代表性的山丘区小流域,通过考虑前期30d降雨量、增加经流曲线数(curve number,CN)分级和对SCS模型的常数项进行修正,得到适用于江苏省山丘区小流域的SCS产流模型;并将其与基于地形地貌参数的Nash汇流模型结合,构建了山丘区小流域的SCS-Nash水文模型,并选取江苏中部的中田舍小流域进行验证。结果表明:构建的SCS-Nash模型具有较好的适用性,可为研究区域小流域的PUB问题提供参考。

| Abstract: | The impact of climate change human activities has affected the consistency of historical hydrologic data,which has gradually turned these areas into data deficient areas or areas without data.The problem of Prediction in Ungauged Basins (PUB) has been a research hotspot in the world.The PUB problem in small watersheds in hilly areas is one of the difficulties.In recent years,some hydrological models based on the physical characteristics of watersheds have been applied to hydrological simulations in the areas lacking data or without data.This reduced the dependence of hydrological simulations on historical data,and provided a good opportunity to study the mechanism of runoff generation and convergence in areas without data. |
