摘要 在黄前水库观测资料的基础上,运用距平分析和假设检验的方法,分析了黄前水库来水年内分配不均、年际变化显著,尤其是近二十年来水系列年际变化更加显著等特点。系统分析了流域降水、蒸发、森林植被等来水影响因素的影响时机和影响程度。由于流域降水是影响黄前水库来水量的最重要的影响因素,建立了水库来水量与流域降水量之间的线性关系。这些分析结果对黄前水库的合理开发与利用有指导作用。 Based on observed data of Huangqian Reservoir, this paper analyzes Huangqian Reservoir's inflow characteristics by the anomaly analysis method and the hypothesis testing method. It is concluded that the inflow of Huangqian Reservoir distributed unevenly in different time and varied greatly annually, especially in the past 20 years. Besides, it systematically analyzes the occasions and degrees of the inflow influence factors, such as precipitation of this drainage area, evaporation and forest vegetation. The rainfall is the most important factor for inflow of Huangqian reservoir, so the linearity relationship can be established between the reservoir's inflow and its precipitation volume. Those analyzed result has guided function for reasonable exploitation and utilization of Huangqian Reservoir.
