摘要
为定量评估澜沧江中上游及元江水电开发对水资源的消耗并判断其影响因素,同时与全流域对比澜沧江中上游水电开发水资源消耗水平,以澜沧江中上游和元江两个不同水热、地形条件的干流水库为研究对象,采用总蒸发水量法计算水电站水足迹。结果表明:元江干流的2座水电站水足迹平均值为3.19 m^3/GJ,澜沧江4座水电站平均值为0.51 m^3/GJ,均低于全国水平,显示出澜沧江中上游水电开发巨大优势。气温对计算结果影响最大,其次是地形因素。
In order to quantitatively evaluate the water consumption of the middle and upper reaches of the Lancang River and the Yuanjiang River hydropower development and determine its influencing factors,the water consumption level of the middle and upper reaches of the Lancang River for hydropower development is compared with that of the whole basin.The main stream reservoir is the research object,and the consumptive water use method is used to calculate the water footprint of the hydropower station.The results show that the average water footprint of the two hydropower stations on the mainstream of the Yuanjiang River is 3.19 m^3/GJ,and the average of the four hydropower stations of the Lancang River is 0.51 m^3/GJ,which are lower than the national level,showing the advantages of hydropower development in the upper and middle reaches of the Lancang River.Temperature has the greatest influence on the calculation results,followed by topographical factors.
