黄河发源于青海省巴颜喀拉山北麓,流经青海、甘肃等九个省(区),全长5464公里。流域面积75.24万平方公里。 黄河下游龙羊峡至青铜峡河段(简称龙～青段),全长1023公里(包括龙羊峡水库),穿经青、甘、宁三省(区)十七个县(市),区间流域面积14.36万平方公里。集中落差达1465米(包括龙羊峡水电站库水位壅高出2600米高程),平均水流坡降为1.44米/公里。龙～青河段水力资源理论蕴藏总量1133万瓩。年发电量992.6亿度。龙～青河段穿经龙羊峡等17个峡谷,13个大川地。为了保留这些富饶的川地,因此在龙～青段规划中仅布置15个梯级如图1、2,利用的最大落差1073米,装机容量1246.4万瓩,年发电量500.6亿度。也就是说:保留的13个大川地,总计落差达390米,近期和远景内不予开发利
The Yellow River originated in the northern foot of Bayanhar Mountains in Qinghai Province, flowing through nine provinces (districts) such as Qinghai and Gansu, with a total length of 5464 kilometers. Watershed area 752,400 square kilometers. Longyangxia to Qingtongxia reach in the lower reaches of the Yellow River (referred to as the Long ~ Qing segment), a total length of 1023 kilometers (including Longyangxia Reservoir), through the Qinghai, Gansu and Ning provinces (districts) seventeen counties (cities) The basin area of 143,600 square kilometers. Concentration gap of up to 1465 meters (including Longyangxia Hydropower Station reservoir water level 壅 2600 meters above sea level elevation), the average water flow gradient down to 1.44 m / km. Dragon ~ Qinghe hydraulic theory reserves a total of 11.33 million 瓩. Annual generating capacity of 99.26 billion degrees. Long ~ Qinghai section through the Longyang Gorge and other 17 canyons, 13 Okawa. In order to preserve these fertile land in Sichuan, only 15 steps are arranged in the planning section of Longmen-Qingqing, as shown in Fig. 1 and Fig. 2, and the maximum difference is 1073 meters. The installed capacity is 12.464 million tons and the annual generating capacity is 50.06 billion kilowatt-hours. In other words: the remaining 13 Okawada, a total drop of 390 meters, the near future and long-term development will not benefit
