| 摘 要： | 采用五点滑动平均法、趋势系数法、Mann-Kendall趋势检验法和方差分析法对大伙房水库流城1951～2006年的降水资料进行了分析.结果表明,1980年前年降水序列明显下降,1980年后微弱上升;季降水序列中夏季降水与年降水变化基本一致,秋季降水明显下降,春,冬两季降水变化趋势不明显;年降水和季降水序列均具有明显的周期变化规律.这些规律可为大伙房水库流域降水的中长期变化趋势估报提供参考.

| Abstract: | The precipitation data of Dahuofang reservoir basin in the past 60 years were analyzed by methods of five dots average slippage,trend coefficient,Mann-Kendall test and variance analysis.The results showed that: annual precipitation series decreased obviously before 1980,and increased slowly after 1980;seasonal precipitation series had different variable trend,summer precipitation series were essentially accordant with annual precipitation series,autumn precipitation series decreased markedly,variation of sp... |
