| 释义 |
The Lualaba River flows entirely within the eastern Democratic Republic of the Congo. It is the greatest river source (headstream) of the Congo River by volume of water. The Lualaba is {{convert|1800|km|mi}} long. Its headwaters are in the country's far southeastern corner near Musofi and Lubumbashi in Katanga Province, next to Zambia. The Chambeshi River is the longest river source (headstream) of the Congo. GeographyThe origination of the Lualaba River is on the Katanga Plateau, at an elevation of {{convert|1400|m|ft}} above sea level. Its total course flows northward to end near Kisangani, where the name Congo River officially begins. From the Katanga Plateau it drops, with waterfalls and rapids marking the descent, to the Manika Plateau. As it descends through the upper Kamalondo Trough (Upemba Depression), {{convert|457|m|ft}} in {{convert|72|km|mi}}, near Nzilo Falls it is dammed for hydroelectric power at Nzilo Dam. At Bukama in Haut-Lomami District the river becomes navigable for about {{convert|640|km|mi}} through a series of marshy lakes in the lower Upemba Depression, including Lake Upemba and Lake Kisale. Ankoro lies on the west bank of the Lualaba River, opposite its confluence with the Luvua River from the east. Some geographers call the combined river below this point the "Upper Congo".[1]Below Kongolo, the river becomes unnavigable as it enters the narrow gorge of Portes d'Enfer (Gates of Hell). Between Kasongo and Kibombo, the river is navigable for about {{convert|100|km|mi}}, before rapids make it unnavigable again between Kibombo and Kindu-Port-Empain. From Kindu up to the Boyoma Falls at Ubundu, the stream is navigable again for more than 300 kilometers. The Boyoma Falls or Stanley Falls are made up of seven cataracts, over a stretch of {{convert|100|km|mi}} of the river, between Ubundu and Kisangani. The river's end is marked after the seventh cataract, near Kisangani, where its name becomes the Congo River.

HistoryThe Lualaba River was once considered a possible source of the Nile, until Henry Morton Stanley journeyed down it and proved that it drained into the Atlantic Ocean.[2] Stanley himself referred to it as the Livingstone. "Had not Livingstone spoken of the river at Nyangwe as the Lualaba, I should not have mentioned the word except as a corruption by the Waguha of the Wenya term Lu-al-ow-wa..."[2]{{rp|114,135}} French colonial governor Pierre Savorgnan de Brazza also explored the Lualaba.
