澜沧江中下游(功果桥至南阿河口)河段,全长772公里,可利用落差达828米。水电开发规划共分8个梯级(即功果桥、小湾、漫湾、大朝山、糯扎渡、景洪和橄榄坝、南阿河口),梯级总装机容量1370万kW,保证出力713.3万kW,年发电量708.6亿kWh,全部建成后可替代火电煤耗每年约为3500多万吨,具有显著的经济效益和社会效益,对振兴云南经济至关重要。澜沧江中下游河段,地处云南西部地区,本河段承接了来自上游铁门坎以上唐古拉山和青藏高原九万多平方公里的降水和融雪水量,河流自北向南切割于横断山和云岭、无量山之间,穿行于怒江、大理、保山、临沧、思茅和西双版纳等6专(州)的29个县(市)所属地区。南北地理位置:自北纬21°46′～25°55′,纵跨4°09′。区间流域面积
The middle and lower reaches of the Lancang River (Gongguoqiao to the South A Estuary) River, a total length of 772 km, the available drop of up to 828 meters. The hydropower development plan is divided into 8 steps (ie Gongguoqiao, Xiaowan, Manwan, Dachaoshan, Nuozhadu, Jinghong and Olive Dam and Nan’a Estuary) with a total installed capacity of 137 million kW and a guaranteed output of 7,133,000 kW, and an annual generating capacity of 70.86 billion kWh. After all the coal-fired power units are built, the coal-fired power consumption will be about 35 million tons per year, which has significant economic and social benefits and is of vital importance to the revitalization of Yunnan’s economy. The middle and lower reaches of the Lancang River, located in the western part of Yunnan Province, undertake the precipitation and snow melting water from the Tanggula Mountain above the upper iron gate and the more than 90,000 square kilometers of the Qinghai-Tibet Plateau. The river cuts from Hengduan Mountain and Yunling from north to south, Between Wulishan, they travel through the 29 counties (cities) belonging to 6 prefectures (prefectures) such as Nujiang, Dali, Baoshan, Lincang, Simao and Xishuangbanna. North and South Geographic location: From latitude 21 ° 46 ’to 25 ° 55’, longitudinal 4 ° 09 ’. Interval basin area
