| 摘 要： | 南方红壤丘陵区洪涝和季节性干旱灾害并存,合理划分汛、枯水期可为旱涝灾害防控提供科学依据。本文选取并统计赣江上中游国家气象站、水文站旬最大1日降水量、旬最大3日降水量、旬降水总量和旬平均流量,采用集对分析,将赣江上中游流域汛期划分为2月1~28日为汛前期,3月1~31日为前汛期,4月1日~6月30日为主汛期,7月1日~9月10日为汛后期,9月11日~次年1月31日为枯水期。集对分析汛期分期结果与传统汛期相近,理论基础完善,可用于赣江上中游流域水资源综合管理。

| Abstract: | Floods and droughts exist in hilly red soil areas of the South China. The flood and drought season division can be used to control the disaster as a scientific base. This paper, based on maximum 1-day and 3-days and total precipitation and streamflow in 10-days, divided the flood and drought season into the period earlier than the flood period (Feb.1-28), early flood period (Mar.1-31), flood period (Apr.1-Jun.30), late flood period (Jul.1-Sep.10) and drought period (Sep.11-Jan.31 next year) in the middle and upper reaches of the Ganjiang River by set pair analysis. The result is closely to traditional one. So the set pair analysis can be applied to integrated water resources management with a relatively complete theoretical base. |
