| 摘 要： | 以重庆市的沙坪坝、涪陵、万州、奉节和湖北省的宜昌5个站为代表，从降水、气温、日照、风速和蒸发等5个要素系统地分析了三峡库区1951-2006年夏季的气候变化特征。结果表明：三峡库区夏季降水量总体呈增加趋势，特别是在20世纪70年代末发生了一次明显跃变；最高气温、平均气温、日照时数以及蒸发量等总体呈下降趋势，在20世纪80年代初发生了一次明显跃变；平均最低气温和平均风速的变化趋势不明显，但所有气候要素均表现出明显的年代际变化特征。

| Abstract: | Based on historical records of precipitation, temperature, sunshine duration and wind speed at 5 stations including Chongqing, Fuling, Wanzhou, Fengjie and Yichang, the changes in these climate elements in summer over the Three Gorges area during 1951-2006 were analyzed. Results show that the regional average of summer precipitation had an overall increasing trend and a jump change occurred in the end of the 1970s. Meanwhile, maximum temperature, mean temperature, sunshine duration and water surface evaporation had a declining trend and a jump change happened in the early 1980s. At the same time, minimum temperature and wind speed did not have an obvious trend. All of these variables showed obvious decadal variations. |
