摘　　要：黄河花园口以上地区多属半湿润、半干旱或干旱地区,水库和淤地坝等蓄水工程运用后将增加当地蒸发损失。通过调查资料统计、实地测量、遥感和设计资料查询等途径,分析了该区水库和淤地坝工程的蓄水特点,分别计算了水库、骨干坝和淤地坝的新增蒸发损失。研究表明:花园口以上现状蓄水工程的新增蒸发损失约为17.9亿m3/a,其中水库新增蒸发损失为15.1亿m3/a、占84.4%,骨干坝新增蒸发损失为2888万m3/a、占1.6%,淤地坝新增蒸发损失为2.54亿m3/a、占14.0%。The areas above Huayuankou in the Yellow River mostly belong to semi-humid or semi-arid or arid areas,so water storage projects such as reservoirs and warping dams will increase the local evaporation losses. By the way of design data query,site visits,measurement and remote sensing survey,this article analyzed the impoundment characteristics of the reservoir and warping dams,and calculated the added evaporation loss of reservoirs,the key dams and warping dams respectively. The outcomes show that the added annual evaporation loss of water storage projects a-bove Huayuankou is about 1. 79 billion m3 ,among the added evaporation loss,that of reservoirs is 1. 51 billion m3 ,accounting for 84. 4% ;that of the key dams is 28. 88 million m3 ,accounting for 1. 60% ;that of warping dams is 0. 254 billion m3 ,accounting for 14. 0% .
