Anadyrsky District ((ロシア語:Ана́дырский райо́н); Chukchi: ) is an administrative〔Law #33-OZ〕 and municipal〔Law #148-OZ〕 district (raion), one of the six in Chukotka Autonomous Okrug, Russia. It is located in the central and southern parts of the autonomous okrug and borders with Chaunsky District in the northwest, Iultinsky District in the north and northeast, the Gulf of Anadyr in the east, Koryak Okrug in the south, and with Bilibinsky District in the west and northwest. It also completely surrounds the territory of the town of okrug significance of Anadyr. The area of the district is .〔Official website of Anadyrsky District. (General information ) 〕 Its administrative center is the town of Anadyr (which is not administratively a part of the district).〔 Population: In terms of area, this is the largest district in the autonomous okrug. The district is located in a mountainous region, the peaks of which provide the catchment areas for the Anadyr River and its tributaries. The district is home to a large number of indigenous peoples as well as Russians and Ukrainians. Humans have been living in what is now Anadyrsky District for at least five thousand years. Following the foundation of the first Russian-speaking settlements by Semyon Dezhnyov, this territory became the key part of the region in terms of trade, exploration, and administration, which still continues today. ==Geography== Anadyrsky District is the largest district within Chukotka,〔Andreev, A. V., pp. 14–15〕 with the territory of the district corresponding closely to the basin of the Anadyr River. It covers much of the interior of Chukotka. The eastern border consists of a coastline on the Bering Sea.〔 The vastness of the district means that natural conditions within it vary considerably, from the mountainous tundra found in the north, to impenetrable woodland in the south, to wind-lashed coast to the east. The district, particularly its eastern part, is dominated by the long Anadyr River, which forms an estuary known as the Anadyrsky Liman emptying into the Gulf of Anadyr. All of the major inhabited localities on the territory of the district (Anadyr, Ugolnye Kopi, and Shakhtyorsky) are found on the banks of this estuary. The boundary between the estuary and the Gulf of Anadyr is marked by the Russkaya Koshka (where "koshka" is a local term meaning "a spit"). The vast majority of all inhabited localities of any size are to be found either along the Anadyr or one of its tributaries. The Anadyr Plateau and Pekulneysky mountain range are found in the north and northwest of the district, within which the upper reaches of the Anadyr River drain.〔 More southerly tributaries of the Anadyr River, such as the Mayn, have their sources in the spurs of the Koryak Mountains in the south of the district.〔 The northeastern-most extent of the taiga is found in the west of the district, on Opalyonnaya Mountain, near the ''selo'' of Markovo.〔 A large part of the district is covered by the Anadyr Valley, consisting of two distinct sections: a plain extending from Anadyrsky Liman in the east approximately to Markovo and a more elevated region within the Shchuchy Range.〔 For a district dominated by a major river and its tributaries, it is unsurprising that the interior is dominated by wetlands covering tens of thousands of square kilometers.〔 These wetlands create innumerable small lakes, although only there is only one large lake, Lake Krasnoye with the area of , in the entire district.〔 The Anadyr Valley opens out into a large estuary containing the Gulf of Onemen and the Gulf of Anadyr. The district is also home to Lake Elgygytgyn, found in the center of an impact crater created just under three and a half million years ago. The easternmost part of the district is covered by the Uelkalskaya tundra, and the area of the Anadyr Estuary contains a number of shingle spits and intertidal silt flats.〔 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「Anadyrsky District」の詳細全文を読む スポンサード リンク
