| 摘 要： | TOPMODEL模型是以地形为基础的半分布式流域水文模型，被广泛地应用于流域水文模拟中．用该模型对东江流域中的四个流域进行枯季日径流过程模拟，在对模拟结果进行初步分析的基础上，着重以连续多日最小平均流量、基流分割结果等描述枯水径流特点的枯水特征值为研究对象，分析用TOPMODEL模型所模拟出来的枯水流量的模拟精度．综合研究结果表明，采用该模型来模拟枯水期的流量过程可以达到较高的模拟精度． |
| 关 键 词： | 枯水径流 TOPMODEL模型 最小流量 基流分割 东江流域 |

| Abstract: | TOPMODEL model is a semi-distributed physically watershed hydrological model based on geography, and it has been applied in many hydrological modeling problems. Daily runoffs during low flow were simulated with the model for the four study basins in the Dongjiang watershed. Simulated results were firstly analyzed. The paper further focuses on describing the variety of low flow characteristics, for example, minima flow for different averaging intervals and baseflow separation. Based on the above low flow characteristics, simulated precision of low flow calculated by TOPMODEL model was evaluated. Plenty study results showed that higher simulated precision during low flow may be received with the model. |
| Keywords: | low flow TOPMODEL model minimum flow base flow separation Dongjiang Basin |
