中文摘要对三峡库区及其周边12个气象站点1951—2010年的气象要素特征值进行了线性回归分析、阶段性分析和趋势分析,结果表明:①三峡库区气温呈上升趋势,年均气温、年均最高气温和年均最低气温的增速分别为0.12、0.12、0.16 ℃/10 a,年均相对湿度以-0.03%/10 a的速率呈下降趋势;②库区蓄水后,绝大多数站点不仅年均相对湿度低于多年均值,而且蓄水后多年均值也低于蓄水前的;③蓄水后,平均相对湿度的变化与潜在蒸散量、降水量的变化并不一致
英文摘要Abstract:The linear regression analysis,stage analysis and trend analysis were applied to analyze the climate change trend on the basis of the year
toyear meteorological data from 12 climate stations in and around the Three Gorges Reservoir area during 1951 - 2010. The results show that:①
temperature in the Three Gorges Reservoir area shows a increasing trend,the annual mean temperature,the maximum temperature and the minimum
temperature increase at the rates of 0. 12,0. 12,0. 16 ℃ /10 a respectively. The annual mean humidity has in a decreasing trend,dropping at the
rate of -0. 03% /10 a;②in the most climate stations,not only annual mean humidity is lower than longtime average annual value,but also annu
al mean value after water storage is lower than that of before water storage in the Three Gorges Reservoir area;③the variation of the mean humidity
is inconsistent with the variation of potential evapotranspiration or precipitation after storing water
