Yandang Mountains or Yandangshan (Chinese: t , s , p ''Yàndàng Shān'', lit. "Wild Goose Pond Mountain(s)") refers, in the broad sense, to a coastal mountain range in southeastern Zhejiang province in eastern China, covering much of the prefecture-level city of Wenzhou (from Pingyang County in the south to Yueqing County in the northeast) and extending to the county-level city of Wenling in Taizhou prefecture. The mountain range is divided in two by the Oujiang River, the two parts being the North Yandang and South Yandang. More narrowly, Yandangshan is also used more narrowly to refer to , a specific part of the North Yandang around an ancient caldera near a small town of the same name (, ''Yàndàng Zhèn''). The highest peaks of North Yandang are located here, and this is also the main tourist spot. In this article, name "Yandang Mountains" is used to refer the mountain range and "Mt. Yandang" to refer to the caldera. The main peak of North Yandang, Baigangjian (, ''Bǎigǎng Jiān'', lit. "Hundred-Peak Point"), rises above sea level〔(Scenic Wenzhou ), Foreign Affairs Office of Wenzhou City〕 There is a radar station on the peak, which is closed to the public. In 2004, Yandangshan became National Geological Park and in the beginning of 2005, a member of Global Geoparks Network, with total area of .〔 The Yandangshan National Forest Park has an area of , covering Mt. Yandang.〔(Yandangshan National Forest Park ) Forestry Bureau of Wenzhou City (in Chinese)〕 Mt. Yandang is known for its natural beauty, arising from its many vertical rock faces and pinnacles, mountain slopes with lush forests and bamboo groves, streams with clear water, waterfalls and caves. The area also hosts numerous temples and shrines, many of them with a long history; characteristic for the temples is that many of them are built inside caves or in mouths of caves. ==Environment== Yandang Mountains were formed through volcanic activity during the Cretaceous period -120 million years (Ma) ago.〔(Yandang Mountain ), UNESCO World Heritage Centre, Tentative Lists〕 Similar igneous rocks are widespread in SE China, forming a ~ wide and ~ long belt of volcanic-intrusive complexes. Yandangshan caldera is a round volcanic‐intrusive complex with a diameter of , of which the north-east part was destroyed by a later regional fault.〔 Yandangshan volcano erupted in four episodes. The mountain consists of various igneous rocks: ignimbrite, rhyolite, syenite and tuff.〔(Petrogenetic sources and tectonic characteristics of Yandangshan caldera, Zhejiang Province ) Feng, C.G., Yu, Y.W., and Dong, Y.H., 1997, Geology of Zhejiang 13:18–25 (in Chinese with English abstract)〕 The mountain shows often conspicuous layering corresponding to the four different episodes of eruptions, giving rise to terrace-like structures where flatter, forested areas are separated by vertical cliffs. Mt. Yandang is mostly covered by deciduous and evergreen forests, mixed with some ''Cunninghamia''. Drier ridges can be dominated by small pine trees. There are also some bamboo grooves. Lower slopes and valleys are used for agricultural purposes, for example for growing tea, or as fruit gardens. Herbs and mushrooms collected from the mountain are sold locally. A number of plant and animal species have been named after Mt. Yandang. A species of sedge, ''Carex yandangshanica'', has been described from Mt. Yandang and two other mountainous locations in Zhejiang. Mt. Yandang has also given its name to ''Cyclosorus yandangensis'', a marsh fern, and ''Arachniodes yandangshanensis'', a holly fern.〔(Catalogue of life ) The Biodiversity Committee of Chinese Academy of Sciences (eds.), 2010, Catalogue of Life China: 2010 Annual Checklist China. Species 2000 China Node, Beijing, China〕 Among animal species, a mite ''Eustigmaeus yandangensis'' has been named after Mt. Yandang, but this has been challenged. Yandang Mountains are everywhere influenced by human activity; there is an extensive network of official tourist paths, clearings for fire-prevention, and unofficial paths used by the local people for collecting resources from the mountains; nevertheless, because of the steep terrain, some parts are difficult to access. Whatever wildlife survives tends to be very elusive. Notable inhabitants of Yandang Mountains include Cabot's tragopan, a nationally-protected species in China.〔(BirdLife International (2012) Species factsheet: ''Tragopan caboti'' )〕 Chinese pangolin is also reported to live in Yandang Mountains.〔(http://www.ydspark.com/ )(in Chinese)〕 Yandang Mountains have been considered as one of the areas where South China tiger might still persist, but there is no positive evidence and the species is considered functionally extinct in the wild.〔(Is the South China tiger extinct in the wild? ) Save China's Tigers, accessed 21 Feb 2012〕 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「Yandang Mountains」の詳細全文を読む スポンサード リンク
