【摘要】 通过对三峡库区及其周边地区33个气象观测站1971-2006年降水与温度观测资料的统计分析,表明:三峡水库蓄水后水库水域扩大对周边地区降水量影响不大,近几年降水较常年偏少趋势与西南地区大的气候背景一致。三峡水库蓄水后受水域扩大影响近库地区的气温发生了一定变化,表现出冬季增温效应,夏季有弱降温效应,但总体以增温为主。更多还原

【Abstract】 Based on the rainfall and temperature observation data of 33 stations in the Three Gorges(TG) area during the period 1971 to 2006,the climate characteristics of rainfall and temperature changes since the water storage of Three Gorges Reservoir are analyzed.The results show that the decreasing rainfall trend is found in the past three years over the TG area,which is consistent with the climate change over Southwest China.The expanding water area of reservoir seems to have increasing temperature effect in winter and decreasing effect in summer,with a yearly total increase in temperature since the water storage of Three Gorges Reservoir.更多还原
