摘要 随着社会经济的发展,人类活动频繁,使下垫面条件发生改变,暴雨洪水演变关系也发生着改变。根据第二松花江丰满以上流域的相关水文资料,应用Mann-Kendall趋势检验法,分析了1956-2010年历史暴雨、1953-2010年历史洪水的变化规律和趋势,研究了暴雨年际变化和洪水次降雨量和次洪量趋势,探讨了暴雨洪水相关关系,结果表明:在55年中,历史暴雨量有先减小后增大之后回落的趋势;洪水多出现在7、8月份,且洪量分布中以白山~丰满区间为主的洪水居多;次洪变化和暴雨变化呈同步上升趋势;五道沟以上流域次洪上升趋势比次降雨量变化幅度小,是由于水利工程较多、人类活动影响剧烈所致。研究结果可为防洪减灾和流域水库调度提供一定理论依据。 With the development of social economy, human activities are frequent, which changes the conditions of the underlying surface and also alters the relationship between the storm and flood evolution law. Based on the relevant hydrological data of upstream to Fengman Reservoir in the second Songhua River Basin, this paper analyzes the change law trend of historical storms from 1956 to 2010, historical floods from 1953 to 2010 Mann-Kendall trend correlation tests. Meanwhile, it analyzes the trend of storm annual variations and flood sub- rainfall and sub-flood, and explores the relative relationship between storm and flood. The results show that the historical storm rainfall has a trend of decrease first and increase then, dropping in the last 55 years. Flood often appears in July and August, and flood is distributed in the interval of Bai-Feng mostly. The trend of sub-flood and storm is rising simultaneously. The variation amplitude of the sub-flood's upward trend is smaller than the sub-rainfall in the Wudaogou Basin because of water conservancy projects and human activities. This study can provide a theoretical basis for the control of floods and the schedule of reservoirs.
