【摘要】：香溪河流域是三峡库区的代表性流域,研究其径流量变化规律有重要意义,但目前尚缺乏对月尺度下各类径流统计量的分析。对此,以香溪河流域兴山水文站近40年(1969~2008年)径流量为基础,利用最大熵方法分析了香溪河流域的月径流变化特征。结果表明,最大熵方法可有效模拟香溪河流域的月径流量概率分布,体现其统计特征,优于P-Ⅲ型分布;香溪河流域具有显著的丰枯季节变化,且平均月径流量最高点发生了变异;香溪河流域的月径流量存在缓慢下降的趋势,且1、5、9、10、12月份发生了变异。研究结果为水利工程规划、设计提供了依据。
[Abstract]:Xiangxi River Basin is a typical watershed in the Three Gorges Reservoir area, it is important to study the variation of runoff, but there is still a lack of analysis of the statistics of the monthly runoff scale. In this regard, in Xiangxi River Watershed of Xingshan hydrological station in recent 40 years (1969~2008 years) runoff as the basis, using the maximum entropy method analysis of the monthly runoff the change characteristics of Xiangxi River Basin. The results show that the maximum entropy method can effectively simulate the Xiangxi watershed runoff probability distribution, reflect the statistical characteristics, is better than that of P- type III distribution; Xiangxi River Basin has abundant seasonal variation. The variation of average monthly runoff and the highest point; Xiangxi watershed month runoff has a slow downward trend, and 1,5,9,10,12 month variation. The results for the water conservancy project planning, provide the basis for the design.
