摘　　要：根据红水河干流梯级开发前后,天生桥至迁江河段各水文站水温观测资料和部分水库水温实测数据,采用对比和相关分析的方法,探讨了水电梯级开发对水温的累积影响。研究结果表明:天生桥一级水库和龙滩水库水温结构为分层型;天生桥一级水库下游梯级春、夏两季水温明显低于建库前河流水温,秋、冬两季则有所提高,影响程度随下游距离增加逐渐减小,影响距离约300 km。研究成果可为评价水电梯级开发对水温的影响并制定减缓影响的对策提供依据。The cumulative effects on water temperature caused by the hydropower cascade development were studied by comparing the monitoring data before and after the developments in Hongshui River between Tianshengqiao and Qianjiang.The results show that,the water temperature structures of Tianshengqiao I and Longtan reservoir are stratified,the water temperatures in the downstream of Tianshengqiao I Reservoir in spring and summer are significantly lower than the data before development and slightly higher in autumn and winter,and the influences of Tianshengqiao I on downstream water temperature is gradually decreased with the increase of distance and the maximum influence distance is about 300 km.The study provides the basis for evaluating the influence on water temperature caused by hydropower cascade development and developing mitigation countermeasures.
