中文摘要: 利用1951～2000年间三峡地区上游5个流域区间(乌江流域、重庆—万县、万县—坝区、嘉陵江流域、岷沱江流域)面降雨量资料分析了三峡地区夏季5、6、7、8月及6～8月旱涝分布特点和成因,探讨了若干主要环流系统对这一地区夏季旱涝的影响,建立了长江三峡地区夏季降水趋势概念化预测模型;模型思路清晰,方法简便,历史拟合率较高,2000、2001、2002年三年的预测结果基本是成功的。

Abstract:Based on the area rainfall data in the upper reaches of Three Gorges (including five valley:Wujiang, Chongqing-Wanxian, Wanxian-baqu, Jialingjiang, Mintuojiang) during 1951-2000, the drought/flooding distribution characteristics and its cause in May, June, July, August and summer in the Yangtze Gorges are analyzed. The impact of some main circulation systems on the area is studied, and the prediction models of various basins area rainfall are established respectively. The model predictions are successful during the years of 2000, 2001, 2002.
