Aiming at the difference of the runoff fluctuation regime after the construction of reservoir, this paper adopted several fluctuation quantification methods to analyze the difference of downstream runoff fluctuation regime after the construction of Three Gorges reservoir from the dispersion, tendency and steepness change degrees on the basis of nearly 70-year long time series of runoff data at Yichang hydrologic station. Compared with the natural runoff regime, the results show that the dispersion degree of runoff decreases (mostly in flood control storage capacity reservation period), the tendency change degree of runoff increases and the steepness reduces (mainly in drawdown period), and totally the fluctuation regime changes intricately.

针对水库建设前后径流波动情势的变化,基于宜昌站近70年长系列日径流过程,使用多个波动量化评估方法,从离散程度、趋势转变程度、陡度等角度对比分析了三峡水库建设前后不同时期下游径流波动情势的差异。结果表明,较天然径流情势而言,水库建设后径流的离散程度减小(主要在防洪库容预留期),径流的趋势转变程度增大、陡度减小(主要在消落期),总体上径流的波动情势变化复杂。

针对水库建设前后径流波动情势的变化,基于宜昌站近70年长系列日径流过程,使用多个波动量化评估方法,从离散程度、趋势转变程度、陡度等角度对比分析了三峡水库建设前后不同时期下游径流波动情势的差异。结果表明,较天然径流情势而言,水库建设后径流的离散程度减小(主要在防洪库容预留期),径流的趋势转变程度增大、陡度减小(主要在消落期),总体上径流的波动情势变化复杂。

Aiming at the difference of the runoff fluctuation regime after the construction of reservoir, this paper adopted several fluctuation quantification methods to analyze the difference of downstream runoff fluctuation regime after the construction of Three Gorges reservoir from the dispersion, tendency and steepness change degrees on the basis of nearly 70-year long time series of runoff data at Yichang hydrologic station. Compared with the natural runoff regime, the results show that the dispersion degree of runoff decreases (mostly in flood control storage capacity reservation period), the tendency change degree of runoff increases and the steepness reduces (mainly in drawdown period), and totally the fluctuation regime changes intricately.
