中文摘要: 根据宜昌最近四十多年逐日气象资料和一百多年流量资料，详细分析了大江截流期（10—12月）坝区的一般气候特征和可能影响施工的气温、降水、风、天气现象等演变规律。最后，着重探讨了坝址在截流期（11月）的流量和上游汇水区前期降水量的统计关系，并在此基础上建立了流量的长期预报模式。

Abstract:Based on the daily meteorological data in the recent 40-year and the flow-off data for more than one hundred,the climate features during the damming period in Sanxia area and the variabilities of the weather element,such as temperature,precipitation,wind and weather phenomenon,which would affect the engineering procedures,are analysed in detail.The statistical relationship between the streamflow at dam site during the damming period and precipitation for previous period in the upper reserivor area,and then the long term forecast model of streamflow are established.
