| 本文在2010年版《江西省暴雨洪水查算手册》水文成果数据的基础上，浅析江西省天然流域设计暴雨量与径流系数的关系.当暴雨量超过110mm，暴雨量与径流系数呈反比例函数关系.由全省各气象站实测最大24h点暴雨历史资料，可得到全省天然流域径流系数在0.72～0.97之间.同时本文根据两者的关系，列举在实际工程中的实例应用，可供工程设计人员参考. |
| 英文摘要: |
| The runoff coefficient is an important parameter in engineering design.Based on the hydrological data of the 2010 edition of the“Handbook of Rainstorm and Flood Calculation Manual in Jiangxi province”，this paper analyzes the relationship between the designed rainstorm amount and the runoff coefficient of natural watershed in Jiangxi province.When the amount of rainstorm over 110mm，the amount of rainstorm is inversely proportional to the runoff coefficient.By the historical data of the maximum 24-hour rainstorm measured by all weather stations in the province，the runoff coefficient of natural watershed in the province can be obtained between 0.72 and 0.97.At the same time according to their relationship，listed the actual application in the project instance，for engineering design reference. |
