中文摘要:
      水电开发导致水资源消耗易被忽视,而大规模流域梯级水电开发具有明显的水足迹,以澜沧江中下游干流8座梯级水电站为例,利用水足迹计算方法评估水电站运行期间消耗的水资源,计算水电站水足迹,分析水足迹影响因子。结果表明,8座水电站水足迹平均值为2.23 m3/GJ,低于世界和全国平均水平;水电站间水足迹差异较大,变差系数Cv值为0.65;效能和地形因子是导致水足迹差异的关键因子。
英文摘要:
      The water resources consumption caused by development of hydropower is often neglected. The large scale of basin cascade hydropower development have clear water footprint. Taking the 8 cascade hydropower stations in the middle and lower reaches of the Lancangjiang River as an example, the consumed water resources during the operation of hydropower station were analyzed by means of water footprint. The water footprint of hydropower station was calculated and the influencing factors of water footprint were analyzed. The results show that the average water footprint of the 8 hydropower stations is 2.23 m3/GJ, which is lower than the world and the national average level. The water footprint between the hydropower stations is different and the variation coefficient CV is 0.65. The efficacy and topographical factors are the key factors for resulting in the difference of water footprint.
