| 摘 要： | 三峡水库是否存在低温下泄水流一直是国内外专家学者关注的热点问题之一。本文以三峡大坝上游距离最近的庙河断面作为典型断面，利用2004-2009年实测水温资料，分析三峡水库近坝区水域水温垂向结构，结果表明：三峡水库近坝区目前还没有形成温跃层；温差较大的区域（0-75 m）均位于电站取水口高程（110 m）以下；三峡水库不存在低温水流下泄问题。

| Abstract: | Whether it exist the low-temperature discharge flow in Three Gorges Reservoir is the focus question that the experts and scholars in the domestic and foreign pay close attention to gradually. In this paper, Miaohe section upstream closest to Three-Gorges Dam is as a typical cross-section. Based on the measured temperature data in 2004-2009, the vertical structure of water temperature in the vicinity area of Three Gorges Dam is analyzed. The result shows: it has not yet formed the thermocline in the vicinity area of Three Gorges Dam; the regions of the large temperature gradient (0-75 m) are located below the power plant intake elevation (110 m); Three Gorges Reservoir has no low-temperature discharge flow at present. |
