| 摘 要： | 运用线性回归分析与Mann-Kendall趋势检验法对邯郸地区及各水资源分区的降雨资料进行分析,揭示了该地区及各水资源分区年降水量不断减少的变化趋势及显著性水平,并得出如下结论:各水资源分区年降水量变化规律不一致;随着海拔高度的降低,区域年降水量变化趋势越明显;低海拔区域年平均降水量减少是海河流域年径流量减少的重要原因。 |
| 关 键 词： | 年降水量 统计特性 线性回归分析 Mann-Kendall检验 邯郸地区 |

| Abstract: | The annual precipitation in the Handan region and every water resources subregion was analyzed with linear regression analysis and the Mann-Kendall test, and the variation tendency and significance level of the continuously decreasing annual precipitation in that region and every water resources subregion of were revealed. The conclusion was that the various patterns of different water resources subregion differed; the variation of regional precipitation became more apparent with decreasing elevation above sea level; and the Haihe River was the decrease of annual average precipitation most important reason for the decreasing discharge of the at low elevations. |
| Keywords: | annual precipitation statistical characteristics linear regression analysis Mann-Kendall test Handan region |
