Sydney, New South Wales, Australia is located in a coastal basin bordered by the Pacific Ocean to the east, the Blue Mountains to the west, the Hawkesbury River to the north and the Woronora Plateau to the south. Sydney lies on a submergent coastline, where the ocean level has risen to flood deep river valleys (rias) carved in the sandstone. There are more than 70 harbour and ocean beaches, including the famous Bondi Beach, in the urban area. Sydney's urban area covers 1,788 km² (690 mi²). This area had 3,908,642 people, giving an urban population density of 2037 people per square kilometer. The Sydney Statistical Division, used for census data, is the unofficial metropolitan area〔''(1217.0.55.001 - Glossary of Statistical Geography Terminology, 2003 )'', Australian Bureau of Statistics, 2003〕 and covers 12,145 km² (4,689 mi²).〔("2032.0 - Census of Population and Housing: Australia in Profile -- A Regional Analysis, 2001" ), Australian Bureau of Statistics, 2004-01-16〕 This area includes the Central Coast and Blue Mountains as well as broad swathes of national park and other non-urban land. At the 2011 census this area had 4,627,345 people.〔(【引用サイトリンク】title=National Regional Profile: Sydney (Statistical Division) )〕 ==Geography== Sydney sprawls over two major regions: the Cumberland Plain, a relatively flat region lying to the south and west of Port Jackson, and the Hornsby Plateau, a sandstone plateau lying mainly to the north of the harbour, rising to 200 metres above sea level within the urban area and dissected by steep valleys such as the Lane Cove River valley. In 1820s, the plain west of Parramatta and Liverpool was described as "a fine timbered country, perfectly clear of bush, through which you might, generally speaking, drive a gig in all directions, without any impediment in the shape of rocks, scrubs, or close forest". This confirmed earlier accounts by Governor Phillip, who suggested that the trees were "growing at a distance of some twenty to forty feet from each other, and in general entirely free from brushwood..."〔Kohen, J., The Impact of Fire: An Historical Perspective, in Australian Plants Online, Society for Growing Australian Plants, September 1996〕 The oldest parts of the city are located in the flat areas south of the harbour; the North Shore was slower to develop because of its hilly topography, and was mostly a quiet backwater until the Sydney Harbour Bridge was opened in 1932, linking it to the rest of the city, with the suburbs surrounding the northern entrance to said bridge effectively developing North Sydney into a second Central Business District. 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「Geography of Sydney」の詳細全文を読む スポンサード リンク
