Amur Oblast () is a federal subject of Russia (an oblast), located on the banks of the Amur and Zeya Rivers in the Russian Far East. The administrative center of the oblast, the city of Blagoveshchensk, is one of the oldest settlements in the Russian Far East, founded in 1856. It is a traditional center of trade and gold mining. The territory is accessed by two railways: the Trans-Siberian Railway and the Baikal–Amur Mainline. As of the 2010 Census, the oblast's population was 830,103. Amur Krai () or Priamurye () were unofficial names for the Russian territories by the Amur River used in the late Russian Empire that approximately correspond to modern Amur Oblast. ==Geography== Amur Oblast is located in the southeast of Russia, between Stanovoy Range in the north and the Amur River in the south, and borders with the Sakha Republic in the north, Khabarovsk Krai and the Jewish Autonomous Oblast in the east, the Heilongjiang Province of China in the south, and with Zabaykalsky Krai in the west. The Stanovoy Range forms the dividing line between the Sakha Republic and Amur Oblast and spreads across the oblast's entire northern border. The Amur–Zeya and Zeya–Bureya Plains cover about 40% of the oblast's territory, but the rest is hilly. Several mountain ranges are to the south of Stanovoy Range and parallel to it, and another mountain chain stretches along the oblast's eastern border with Khabarovsk Krai. Many rivers flow through the oblast, especially in the north, accounting for 75% of the hydropower resources in the Russian Far East. Most of the oblast is in the Amur's drainage basin, although the rivers in the northwest drain into the Lena and the rivers in the northeast drain into the Uda. The longest rivers include the Amur, Bureya, Gilyuy, Nyukzha, Olyokma, Selemdzha, and Zeya. The Zeya begins in the mountains in the northeast, and its middle reaches are dammed to create the huge Zeya Reservoir, which sprawls over . Climate is temperate continental, with cold, dry winters and hot, rainy summers. Average January temperatures vary from in the south to in the north. Average July temperatures are in the south and in the north. Annual precipitation is about . Dwarf Siberian pine and alpine tundra grow at higher elevations and larch forests with small stands of flat-leaved birch and pine forests grow alongside the river plains. These larch and fir-spruce forests form the watershed of the Selemdzha River. The Bureya and Arkhara Rivers, southeast of the Selemdza, have the richest remaining forests in the oblast with Korean pine, Schisandra chinensis, Mongolian Oak, and other Manchurian flora. The Zeya–Bureya Plain, located between the Zeya, Amur, and Bureya Rivers, has the highest biodiversity in Amur Oblast. Much of this plain has been burned for agriculture, but large patches still remain. Japanese Daurian and Far Eastern western cranes nest here, as well as a host of other rare birds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amur Oblast」の詳細全文を読む スポンサード リンク
