The largest river in Korea, it flows along the border between North Korea and China. It is also called the Amnok River or Amno River in Korean and the Yalu River in Chinese. It has a total length of 790.7 km and a drainage area of 62,638 square km, of which 32,064 square km is on the Korean side. It originates from Mt. Paektu and flows south, joins the Hyocheon River at Hyesan, turns west, and merges with the Chosin River, which flows north while cutting a deep gorge in the Gaema Plateau. From Junggang, a town at the northern end of Jagang Province, the river flows roughly southwestward and empties into the Yellow Sea at Ryongampo, receiving tributaries such as the Jaseonggang and Doklogang from the south and the Hunjang from China. The area where the main tributary of the Yalu River flows is the coldest region in Korea, and its settlements are sparsely populated by mountain villages inhabited by forestry workers in the Baekdu primeval forest, miners, and people from the fields. It is a culturally backward region. After Korea was liberated in 1945 and the People's Government was established, the provinces of Jagang and Ryanggang were established as a measure to deal with depopulation in remote areas, and Ganggye and Hyesan were expanded and developed as industrial cities. The main river and its tributaries, which are rich in hydroelectric power, now form the main artery of North Korea's power resources. Since 1929, the tributaries, the Hyocheon River, the Bujeon River, and the Changjin River, have had a generating capacity of 750,000 kilowatts through the basin change ceremony, and in 1941, a dam was built downstream at Supung to generate an additional 700,000 kilowatts of electricity. Even after liberation, the main river, Unbong (400,000 kilowatts), Ganggye (240,000 kilowatts), and Doro River (90,000 kilowatts) have a total generating capacity of 730,000 kilowatts. The area is also rich in forest resources, and the primeval forests of Mt. Paektu were used to transport timber from the Yalu River by raft from Hyesan and Manpo to Sinuiju, but since the construction of the Supung Dam, this is stopped midstream.

北朝鮮と中国の境界を流れる朝鮮第一の川。朝鮮語に基づいてアムノック川あるいはアムノ川、中国語に基づいてヤールー川ともよばれている。全長790.7キロメートル、流域面積6万2638平方キロメートル、うち朝鮮側3万2064平方キロメートル。白頭山(はくとうさん/ペクトサン)に発して南流し、恵山(けいざん/ヘサン)で虚川江(きょせんこう/フオチョンカン)をあわせて方向を西に転じ、蓋馬(かいま/ケーマー)高原に深い峡谷を刻みながら北流している長津江(ちょうしんこう/チャンチンカン)と新波で交流している。慈江道(じこうどう/チャカンド)北端の町、中江(ちゅうこう/チュンカン)からは、おおむね南西方向をとり、竜岩浦(りゅうがんぽ/リョンアムポ)で黄海に注いでいるが、その間、南から慈城江(じじょうこう/チャソンカン)と禿魯江(とくろこう/トクロカン)、中国から渾江(こんこう/フンチヤン)などの支流を入れている。鴨緑江の本支流地域は朝鮮でもっとも寒い地帯で、集落も白頭原始林の山林労働者や鉱山に従事する労働者、火田民などの山村集落がまばらにある文化の遅れた地帯であった。1945年に朝鮮が解放され、人民政権が樹立されてから、僻地(へきち)過疎対策として慈江道、両江道(りょうこうどう/リャンカンド)を新設し、江界(こうかい/カンゲ)、恵山を工業都市として拡大発展させた。包蔵水力の豊富な本・支流はいまや北朝鮮の動力資源の大動脈をなしている。1929年以来、支流の虚川江、赴戦江(ふせんこう/プチョンカン)、長津江の流域変更式により75万キロワットの発電能力を得ていたが、さらに41年に下流の水豊(すいほう/スープン)にダムを建設して70万キロワットの電力を得た。解放後も本流の雲峰(40万キロワット)と江界(24万キロワット)、禿魯江(9万キロワット)で計73万キロワットの発電能力を得ている。また森林資源も豊富な地域で、白頭山の原始林は鴨緑江材として、恵山、満浦(まんぽ/マンポ)から筏(いかだ)によって新義州(しんぎしゅう/シンイチュ)まで流していたが、水豊ダム建設以後は中流で止めている。 [魚 塘] 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
