| 摘 要： | 依据漳河水库流域1963-2008年降雨与入库径流资料,利用R/S法对其未来变化趋势进行了分析,发现以1995年为突变点,前后两个系列的统计特征值均具有明显的差异,同时流域地区未来降雨量和径流量可能呈缓慢增加与减少的变化趋势,但未来1月和7月的径流量变化趋势的随机性成份可能很大,而流域人类活动日趋频繁,也使得流域下垫面条件发生了较大的变化,对入库径流量有较大的影响.

| Abstract: | The rainfall and reservoir inflow tendency is analyzed by R/S approach based on the corresponding data of Zhanghe Reservoir from 1963 to 2008.It is found that the two series of statistical eigenvalue varied obviously in 1995 for mutating.The results show that the up-coming rainfall and runoff in river region may slowly increase or decrease,but the runoff from next January to July tends to change at random.And frequent human activities in the watershed also make the underlying surface complicated,which has a great influence on reservoir inflow. |
