【摘要】 通过采用温盐深仪对水布垭水库库区、坝前、坝下水温进行观测,结果表明:水布垭水库坝前水体常年处于温度分层状态,夏季表层与底层温差较大,冬季温差很小;坝下观测断面比坝前断面取水口底板高程处水温高约0~8.0℃;大部分月份坝下断面水温相当于坝前取水口高度以上10~20 m处水温;坝前700 m断面与库中断面分层趋势基本一致;表层水温变化与气温具有较大相关性。更多还原

【Abstract】 A CTD was adopted to observe water temperature of Shuibuya Reservoir,as well as in front of and under the dam. The result showed that water temperature stratification existed in front of Shuibuya Dam for most of the time within a year,the temperature difference between surface and bottom was greater in summer and smaller in winter; the outflow water temperature at observation point under the dam was higher by 0 ~ 8. 0℃ than that of the intake in front of the dam; during most months within a year,outflow water temperature under the dam was the same as that of the location 10 ~ 20 meters above the intake in front of the dam; water temperature stratification of the section700 meters front of the dam was similar to that of the section in the middle of the reservoir; and the water temperature change of surface layer was considerably correlated with air temperature.更多还原
