摘要: 江西省中小河流洪水成因主要有气象因素、暴雨因素和地形地貌因素。结合江西省地区19个中小河流水文站600多场洪水资料数据，分析江西省中小河流洪水特征规律，其结果表明：江西省中小河流洪水存在季节性强、发生频率较高、突发性强等特点和规律，以局部性洪水为主；5~6月份暴雨洪水往往持续时间比较长，洪峰呈现双峰、多峰或者持续时间很长的单峰特征，7~9月份一般是单峰洪水，持续时间相对较短。
Abstract: The main causes of flood in small and medium rivers in Jiangxi Province are meteorological factors, rainstorm factors and topographic factors. Based on the data of more than 600 floods from 19 hydrological stations of small and medium rivers in Jiangxi Province, the flood characteristics of small and medium rivers are analyzed. The results show that there are characteristics and regularities of strong seasonality, high frequency and strong sudden occurrence of flood in small and medium rivers, mainly local floods; rainstorm floods in May-June are frequent. The flood peak presents the characteristics of double peak, multi-peak or single peak with a long duration. In July-September, the flood is usually single peak, and the duration is relatively short.
