摘要
利用溪洛渡坝区三个气象站的观测资料,分析了温湿度、降水、风等气象要素随高度的垂直变化。结果表明:坝址河谷夏长无冬,秋春相连,干湿季节分明;平均气温随高度的升高而降低,旱季垂直递减率接近干绝热变化,雨季接近湿绝热变化,白天垂直递减率加大;夜间多有逆温;平均相对湿度随高度的上升而增加;下垫面风速河谷大于山坡,旱季大于雨季,坝址处全年盛行东南风。
Xiluodu hydropower projecti。planned as a huge water plant aimed at power generating,sand stopping and flood utilization,and also an important part as to develop Jinshajing river,the upper reach of Yangtze River.It locates in the gores of Jinshajing,between Leibo county,Sichuan province and Yongshan county,Yunnan province.
