| 摘 要： | 以汉江上游安康水库和渭河流域临潼站1960-2000年发生的特大洪水资料为依据,对其发生规律进行了对比研究.结果表明,汉江上游和渭河流域特大洪水的发生具有一些共同特征.主要表现在两大流域特大年径流量年份,完全与华西秋雨多雨年份相对应,但特大洪水并不都是发生在华西秋雨异常多雨年份,而是错前错后发生.受到季风活动及地理环境的影响,汉江上游和渭河流域特大洪水的发生又表现出各自的特殊性,汉江上游特大洪水主要发生在初夏和秋季,渭河流域特大洪水主要发生在盛夏和秋季；一年中汉江上游特大洪水发生时间早于渭河流域；渭河流域秋季特大洪水发生时间早于汉江上游特大洪水.

| Abstract: | Based on floods records at Ankang reservoir and Lintong observation station from 1960to 2000,the occurrence characteristics of floods were comparatively analyzed between the upper reaches of HanjiangRiver and Weihe River.The results showed that there were common feature between those two basins interms of flood.The years recorded as extremely large floods in two basins were closely related to the yearsthat had heavy autumn rainfalls in Southwest China.The extreme floods did not always occur in the veryyears that had extreme rainfalls in Southwest China,but right prior to or after those years.As affected byAsian monsoon and regional climate environment,the extreme floods mainly occur in early summer andwhole autumn in upper reaches of Hanjiang River,while in mid-summer and whole autumn in reaches ofWeihe River.Flood occurred generally earlier in upper reaches of Hanjiang River than in Weihe River basinduring ayear,while in autumn flood come earlier in Weihe River basin than in the upper reaches of HanjiangRiver.These findings could provide basic information for weather forecasting and flood controlling in thesetwo basins. |
