摘要
变化环境下水文序列表现出非一致性,形态变化也呈现非单调性甚至非平稳性波动特征,导致传统的水文分析计算和水资源核算面临极大挑战。通过集成不同统计检验参数或方法,提出一套表征水文序列趋势形式及形态变化的指标体系,并以渭河流域咸阳站等7个站点年径流序列为例,验证了该方法的适用性。结果表明,该体系可较为有效地对具有相同Mann-Kendall检验值的不同水文序列的形态变化进行分析与对比,反映水文序列形态变化的宏观特征,实现不同水文数据序列间的空间差异性表征。
Under the changing environment, the hydrological series show inconsistency, and the morphological changes also show non-monotonic or even non-stationary fluctuation characteristics, which leads to great challenges for traditional hydrological analysis and calculation and water resources accounting. By integrating different statistical test parameters or methods, a set of index system was proposed to characterize the trend form and morphological change of hydrological series. The applicability of this method was verified by the annual runoff series of seven stations such as Xianyang Station in the Weihe River Basin. The results show that the system can effectively analyze and compare the morphological changes of different hydrological series with the same Mann-Kendall test value, reflecting the macro-characteristics of the morphological changes of hydrological series, and realizing spatial difference representation among different hydrological data sequences.
