摘　　要：利用新兴县1958—2019年各月降水量、年降水量资料,统计分析新兴县汛期降水气候特征,结果表明:新兴县的两个降水高峰时期(6和8月)都在汛期(4—9月)期间;汛期平均降水量为1 315.1 mm,最多为1 814.2 mm(1994年),最少为565.1 mm(2015年),汛期降水量占年降水量的百分率平均为79.7%,最高达91.4%(1984年),最低为57.3%(2015年);前汛期降水量占年降水量的百分率最高为63.7%,后汛期降水量占年降水量的百分率最高为60.7%。Using the monthly and annual precipitation amount data of Xinxing from 1958 to 2019, this work performs a statistical analysis of the climatological characteristics of precipitation amount in the flood seasons of the county. The results are shown as follows. For Xinxing, two peaks of precipitation(in June and August) all appear in the flood season(from April to September). The average seasonal precipitation amount is 1 315.1 mm, with the most at 1 814.2 mm(in 1994) and the least at 565.1 mm(in 2015), and the seasonal precipitation amount takes up an average of 79.7% of the annual total, with the most at 91.4%(in 1984) and the least at 57.3%(in 2015). For the maximum percentage taken up in the annual total precipitation amount, it is 63.7% for the April-June flood season, and 60.7% for the July-September flood season.
