Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possibl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Indochina Dry Forests
The Central Indochina dry forests are a large tropical and subtropical dry broadleaf forests ecoregion in Southeast Asia. Location and description The ecoregion consists of an area of plateau and low river basin in Cambodia, Thailand, Laos, and Vietnam and includes: *In Thailand the large Khorat Plateau, the higher elevation plains of the Chao Phraya River basin, the foothills of the Tenasserim Hills and other dry areas of the lower slopes of the Khun Tan, Phi Pan Nam and Phetchabun mountain ranges of the north of the country. *In central and southern Laos the wide valley of the Mekong river system. *In Cambodia a large area of the dry plains of the northern, eastern, and south-central parts of the country. *In Vietnam the uplands of the upper Tonlé San and Srepok Rivers. These are the drier areas of Indochina with 1,000-1,500 mm rainfall per year and a long dry season when regular fires occur in the undergrowth, some set intentionally to clear the forest or drive ...

South China Sea Oceanic Islands
The South China Sea Islands consist of over 250 islands, atolls, cays, shoals, reefs and seamounts in the South China Sea. The islands are mostly low and small, and have few inhabitants. The islands and surrounding seas are subject to overlapping territorial claims by the countries bordering the South China Sea. The South China Sea Islands constitute a distinct tropical moist broadleaf forest terrestrial ecoregion, and the South China Sea Oceanic Islands marine ecoregion. Geography The islands, shoals, and reefs are grouped into three archipelagos, plus the Zhongsha Islands (Macclesfield Bank and Scarborough Shoal). The South China Sea Islands as defined here consist of the sea's oceanic islands, and do not include the sea's continental shelf islands like Hainan and Natuna. Collectively, they have a total land surface area of less than 15 km2 at low tide. The island groups include: * The Paracel Islands, disputed between the People's Republic of China (PRC), the Republi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Tonkin
The Gulf of Tonkin is a gulf at the northwestern portion of the South China Sea, located off the coasts of Tonkin ( northern Vietnam) and South China. It has a total surface area of . It is defined in the west and northwest by the northern coastline of Vietnam down to the Hòn La Island, in the north by China's Guangxi Zhuang Autonomous Region, and to the east by the Leizhou Peninsula and Hainan Island. Etymology The name ''Tonkin'', written "" in Hán-Nôm characters and in the Vietnamese alphabet, means "eastern capital", and is the former toponym for Hanoi, the present capital of Vietnam. It should not to be confused with Tokyo, which is also written "" and also means "eastern capital". During the French colonial era, the northern region of today’s Vietnam was called ''Tonkin''. ''Bắc Bộ'' is the native Vietnamese name of Tonkin. The bay's Vietnamese and Chinese names – and , respectively – both mean "Northern Bay". History Gulf of Tonkin incident ...

Gulf Of Thailand
The Gulf of Thailand, also known as the Gulf of Siam, is a shallow inlet in the southwestern South China Sea, bounded between the southwestern shores of the Indochinese Peninsula and the northern half of the Malay Peninsula. It is around in length and up to in width, and has a surface area of . The gulf is surrounded on the north, west and southwest by the coastlines of Thailand (hence the name), on the northeast by Cambodia and the Mekong Delta region of Vietnam, and opens to the South China Sea in the southeast. Names The modern Thai name of the gulf is ''Ao Thai'' ( th, อ่าวไทย, , 'Thai Gulf') and "Gulf of Thailand" has been adopted as the official name of the body by the International Hydrographic Organization. Its name in Malay is he "Gulf of Siam", ''Teluk Siam'', and in km, ឈូងសមុទ្រសៀម'', Chhoung Samut Siem''. In Thai, the gulf is historically known as ''Ao Sayam'' ( th, อ่าวสยาม).

Marine Realm
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction A more complete definition describes them as “Areas of relatively homogeneous species composition, clearly distinct from adjacent systems” dominated by “a small number of ecosystems and/or a distinct suite of oceanographic or topographic features”. Ecologically they “are strongly cohesive units, sufficiently large to encompass ecological or life history processes for most sedentary species.”Spalding, Mark D., Helen E. Fox, Gerald R. Allen, Nick Davidson et al. "Marine Ecoregions of the World: A Bioregionalization of Coastal and Shelf Areas".

Central Indo-Pacific
The Central Indo-Pacific is a biogeographic region of Earth's seas, comprising the tropical waters of the western Pacific Ocean, the eastern Indian Ocean, and the connecting seas. The Central Indo-Pacific is a part of the larger Indo-Pacific, which includes the tropical Indian Ocean, the western and central tropical Pacific Ocean, and the seas connecting the two in the general area of Indonesia. The Central Indo-Pacific may be classified as a marine realm, one of the great biogeographic divisions of the world's ocean basins, or as a subrealm of the Indo-Pacific.Spalding, Mark D., Helen E. Fox, Gerald R. Allen, Nick Davidson ''et al.'' "Marine Ecoregions of the World: A Bioregionalization of Coastal and Shelf Areas".

Mekong Delta
The Mekong Delta ( vi, Đồng bằng Sông Cửu Long, lit=Nine Dragon River Delta or simply vi, Đồng Bằng Sông Mê Kông, lit=Mekong River Delta, label=none), also known as the Western Region ( vi, Miền Tây, links=no) or South-western region ( vi, Tây Nam Bộ, links=no), is the region in southwestern Vietnam where the Mekong River approaches and empties into the sea through a network of distributaries. The Mekong delta region encompasses a large portion of south-western Vietnam of over . The size of the area covered by water depends on the season. Its wet coastal geography makes it an important source of agriculture and aquaculture for the country. The delta has been occupied as early as the 4th century BC. As a product of Khmer, Vietnamese, Chinese, and French settlement in the region, the delta and its waterways have numerous names, including the Khmer term Bassac to refer to the lower basin and the largest river branch flowing through it. After the 195 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mekong River
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water ) is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ''sông'' (from *''krong'') and Mon ''kruŋ'' "river", which led to ...

Hong River
The Red River, also known as the Hong River (; vi, Sông Hồng; Chữ Nôm: 瀧紅; Chữ Hán: 紅河), the ' and ' (lit. "Mother River") in Vietnamese, and the (, ' Nguyên Giang) in Chinese, is a -long river that flows from Yunnan in Southwest China through northern Vietnam to the Gulf of Tonkin. According to C. Michael Hogan, the associated Red River Fault was instrumental in forming the entire South China Sea at least as early as 37 million years before present. The name red and southern position in China are associated in traditional cardinal directions. Geography The Red River begins in China's Yunnan province in the mountains south of Dali. Main headstreams Leqiu River, Xi River and Juli River confluence at Nanjian where they form the Lishe River. The Lishe River meets with another headstream, the Yijie River at Hongtupo, Chuxiong Prefecture. It flows generally southeastward, passing through Yi and Dai ethnic minority areas before leavin ...

Indochina Mangroves
The Indochina mangroves are a large mangrove ecoregion on the coasts of Thailand, Cambodia, Vietnam and Malaysia in Southeast Asia. Location and description Mangrove forests occur on coasts that are regularly washed with saltwater by tidal movements. There are patches of mangrove throughout the region and there were once much more. Today the largest areas remain in the Mekong delta in U Minh District and other parts of Cà Mau Province at the southern tip of Vietnam. There are smaller patches in Vietnam in Cam Ranh Bay in the south and in the Red River delta in the north. Much larger areas of mangrove habitat on the coasts of southern Vietnam including the Mekong and Red River deltas were affected by the Vietnam War when areas of mangrove were cleared or destroyed by bombing and the defoliant Agent Orange, while mangroves around Pattaya and in the Chao Phraya delta in Thailand and the Bay of Kompong Som in Cambodia have been cleared for agricultural and coastal development. ...
