摘　　要：雅砻江二滩水库为河道型深水水库,坝前水深达188 m,1998年建成蓄水发电。目前国内已有的水库水温实测资料,多为水深100 m以下的水库,百米以上水库的水温分布规律研究较少。通过实施原型观测及收集后续原型观测,同时收集坝址下游小得石水文站长系列水温观测资料的基础上,对坝前、库区纵向、下泄水温进行多方面的归纳总结,得出二滩水库库区及下泄水温分布特征,为揭示大型河道型水库水温分布规律提供基础。Ertan Reservoir on Yalong River is a river-type reservoir,built in 1998 with a water depth of 188 m. At present,the measured data of reservoir water temperature are mostly from reservoirs with water depth of less than 100 m,and those above 100 m are rarely studied. Through the field observation on water temperature in Ertan Reservoir and collection of water temperature observation data of Xiaodeshi hydrological station at downstream of the dam,this paper summed up water temperature distribution in front of the dam,the reservoir portrait and discharge water. In addition,this paper can offer the basis for revealing the water temperature distribution of large river-type reservoirs.
