摘　　要：随着新疆经济社会快速发展,水资源日益紧张,用水矛盾愈发凸显,新疆汛期统一时段的粗放式管理与当前水资源集约节约管理要求已不相适宜,因此对新疆分区域划分汛期的工作十分必要和迫切。以金沟河为例,采用洪峰流量分布方法、河道来水占比方法、日洪峰流量分布方法及超警戒流量方法4种方法划分汛期和主汛期时间,并对4种方法优缺点进行对比,选出适合金沟河流域的汛期划分方法,并将该方法应用于新疆其他河流。结果表明,河道来水占比方法确定的汛期及主汛期既合理又符合金沟河流域实际情况,将该方法应用于新疆其他河流,并对新疆分区域划分汛期,综合考虑新疆实际情况最终确定阿勒泰片区汛期为5月1日至8月10日;伊犁河谷、塔额盆地片区汛期为4月21日至8月20日;天山北坡、东疆和南疆片区汛期为6月11日至8月20日。研究结果对新疆防灾减灾和水资源管理具有重要意义。With the rapid economic and social development in Xinjiang Uygur Autonomous Region,water resources are becoming strained,and water use conflicts are becoming prominent.The extensive management of the unified period of flood season in Xinjiang is no longer suitable for the current intensive and economical management of water resources in the autonomous region.Therefore,the regional division of flood season in Xinjiang is very necessary and urgent.Taking Jingou River as an example,the flood season and main flood season were divided by four methods:flood peak flow method,river inflow proportion method,daily flood peak flow distribution method and over alert flow method.The advantages and disadvantages of the four methods were compared,and the flood season classification method suitable for Jingou River basin was selected,and the method was applied to other rivers in Xinjiang.The results indicate that the flood season and main flood season determined by the river inflow proportion method are both reasonable and in line with the actual situation of the Jin'gou River Basin.Applying this method to other rivers in Xinjiang and dividing the flood season in different regions taking into account the actual situation in Xinjiang;the flood season in Altay area was finally determined to be from May 1st to August 10th,the flood season in the Ili River Valley and Ta'e Basin areas is from April 21st to August 20th;the flood season in the northern slope of Tianshan Mountains,eastern and southern Xinjiang areas is from June 11th to August 20th.The research results are of great significance for disaster prevention and reduction,as well as water resource management in Xinjiang.
