| 摘 要： | 本文在基于新安江模型的分布式水文概念模型的基础上,以伊河东湾流域为研究对象,分别采用集总式、半集总式、半分布式三种率定方案进行模型率定和径流模拟,并与传统的集总式水文模型进行成果比较。研究结果表明:总的来说,分布式模型的模拟结果略好于集总式模型;由于考虑了不同子流域参数变异性,半分布式方案要优于其他方案;但随着模型结构的复杂性增加,参数率定的难度增大,模拟结果的不确定性增多,分布式水文概念模型的模拟效率还有待于进一步的提高。

| Abstract: | A distributed hydrologic conceptual model based on the Xinanjiang Model is proposed in this paper. The Dongwan Watershed, a sub-basin of the Yihe River was selected as case study. Three different automatic calibration strategies, which are lumped, semi-lumped, and semi-distributed strategies, are applied for model calibration and runoff simulation. Comparing with the traditional lumped hydrological models, the results show that the distributed model is litter better than the lumped. The semi-distributed strategy is better than the others because of considering the varying the parameters between sub-basins. Since moving from lumped to semi-distributed model creates more complexity in modeling and the calibration procedure, however, more uncertainty increase in the results. Therefore, further study is necessary in order to improve the performance of the distributed hydrologic conceptual model. |
