世界上最长的河流峡谷

 

  雅鲁藏布江大峡谷位于“世界屋脊”青藏高原之上,平均海拔3000米以上,险峻幽深,侵蚀下切达5382米,具有从高山冰雪带到低河谷热带季内雨林等九个垂直自然带,是世界山地垂直自然带最齐全、完整的地方,这里麇集了许多生物资源,包括青藏高原已知高等植物种类的2/3,已知哺乳动物的1/2,已知昆虫的4/5,以及中国已知大型真菌的3/5,堪称世界之最。

  雅鲁藏布江大峡谷怀抱南迦巴瓦峰地区的高山峻岭,冰封雪冻,它劈开青藏高原与印度洋水汽交往的山地屏障,像一条长长的湿舌,向高原内部源源不断输送水汽,使青藏高原东南部由此成为一片绿色世界。雅鲁藏布江大峡谷里最险峻、最核心的地段,是一从白马狗熊往下长约近百公里的河段,峡谷幽深,激流咆哮,至今还无人能够通过,其艰难与危险,堪称“人类最后的秘境”。

  由于雅鲁藏布江大峡谷环境恶劣、灾害频仍,构成人们很难跨越的屏障和鸿沟,其落后与闭塞,使墨脱成了高原上的“孤岛”、远离现代社会的“世外桃源”,至今少有人涉足。1994年,我国科学家组成一科学考察队,对雅鲁藏布江大峡谷进行科学考察,才揭开了雅鲁藏布江大峡谷神秘面纱的一角。

  The Mozambique Strait (Mozambique Channel, Canal de Mocambique in Portuguese)is a waterway in the west of India ocean, is the world's longest Strait, located betweenMozambique and Madagascar Africa Southeast countries.

  The world's longest Strait

  The Mozambique Strait is full-length 1670 kilometers (say 1760 km), was inclinedtoward the southwest northeast. The channel ends middle narrow width, the averagewidth of 450 km, the northern end of the widest point reached 960 kilometers, the middle for 386 kilometers narrowest. Gap in most water depth of 2000 meters, Northand South in the middle of more than 3000 meters, about 2400 meters, the maximumdepth of more than 3500 meters, depth second only to Drake Strait and the Bashi channel.

  The world's longest Strait

  Gap in the surface seawater annual average temperature of 20 degrees Celsius, hot and rainy in summer, when there are caused by the airflow intersection of thehurricane. The depth of gap width, the giant ship but is navigable all year round. Rich lobster, shrimp and sea cucumber Strait, and its tender meat plump and enjoys a high reputation in the world market. Mozambique warm current South, the hot and humid climate. Many coral reef. Zambezi River from the West Bank injection. South the Atlantic with India ocean shipping routes. The two sides have Bella, Maputo, Ma Renjia and other ports.

  The world's longest Strait

  The Mozambique Strait sea transport routes from southern the Atlantic to India ocean,the Persian Gulf oil has a large part to pass through here to Europe, North America,strategic position is very important.
