| 摘 要： | 以湖北省香溪河古洞口水库为例，首先，结合1997—2016年近20 a降水资料，计算分析不同时间尺度(3、6、12、24 h)强降水分布特征; 然后, 选取新安江水文模型，通过40场洪水的模拟率定水文模型的参数; 最后，结合古洞口水库防洪能力，利用水文模型模拟计算该水库不同基准水位和时间尺度条件下的致汛临界面雨量(到达汛限水位所需的面雨量)。模拟试验表明:利用水文模型计算中小流域临界面雨量能模拟计算并直观给出水库不同基准水位和时间尺度条件下的洪水人库过程曲线、水位变化过程曲线与流域致汛临界面雨量，其意义明确，技术方法可行; 在初始条件(基准水位)相同时，时间尺度越小，临界面雨量越小。 |

| Abstract: | Taking the Gudongkou Reservior catchment in Xingshan county, Hubei province as an example, firstly, using the precipitation data from 1997 to 2016, we analyzed the distribution features of heavy precipitation in 3 h, 6 h, 12 h and 24 h time scales. Secondly, choosing the Xin´anjiang hydrological model, we determined hydrological model parameters through the simulation of 40 historical flood cases. Thirdly, based on the simulation results and the flood-preventing capacity of reservoir, we calculated the flood critical area rainfall, that is, the flood limit water level needed reaching the critical area rainfall in different baseline levels and time scales. The results show that it is feasible to use hydrological model to calculate critical area rainfall getting the flood process and water level variation curve in different time scales and base water-levels. It is proved that when the initial condition (base water level) is the same, the smaller the time scale is, the smaller the critical area rainfall is. |
| Keywords: | critical area rainfall flood limit water-level hydrological simulation time scale medium and small catchment |
