摘要
当前,全球气候变化问题是人类迄今为止面临的规模最大、范围最广、影响最为深远的挑战之一,也是影响未来世界经济和社会发展、重构全球政治和经济格局的最重要因素之一。近百年来,世界年平均气温升高了0.4℃～0.8℃,气候变化导致海平面上升,对海洋岛国和大陆沿海地区造成重大负面影响,
The main objective of water level regulation project for Shuikou downstream hydro-junction was to solve the problem of inadequacy of threshold depth of navigation structure and meet the requirements on the draft head of hy- dro-generator. By construction of downstream junction, the water level would reach 7.64 m while discharge is 308 m3/s. During operation of Shuikou hydropower plant, its available water head is limited. The comprehensive analysis showed that the navigation scheme was preferred to navigation and hydropower scheme.
