Lake Baikal
贝加尔湖
俄语: О́зеро Байка́
法語: Lac Baïkal
Crescent-shaped lake Baikal, in Siberia, is only the ninth largest lake in area at 385 miles(620km)in length and 46miles (74km) in width, yet it is easily the largest body of fresh water in the world.The lake harbours more species of plants and animals which are native to the lake, than any other lakes in the world.
贝加尔湖--西伯利亚的一个新月形湖泊,是第九大湖,长385英里,宽46英里,是世界上最大的淡水湖.贝加尔湖有各种各样的植物和动物,其中四分之三是世界其他地方寻觅不到的.
It holds one –fifth of the world’s total freshwater, which is more than the total of all the water in five Great lakes;it holds so much fresh water in spite of its less-than-impressive area because it is by far the world’s deepest lake.
它拥有世界上五分之一的淡水,比五大湖全部的水还多很多。尽管面积不大但淡水很多因为它是世界上迄今为止最深的湖
The average depth of the lake is 1312 feet (400meters)below sea leave and The Olkhon Crevice, the lowest known point ,is more than 5250 feet (1600 meters)deep.
贝加尔湖平均深度是低于海平面1312英尺(400 meters),并且最低点 Olkhon大裂谷 5250英尺(1600米)深.
Lake Baikal, which today is located near the center of Asian Peninsula, is most likely the world’s oldest lake.It began forming 25 million years ago as Asia started splitting apart in a series of great faults.The Baikal Valley dropped away, eventually filling with water and creating the deepest of the world’s lakes.
贝加尔湖位于亚洲次大陆中心,可能是世界上最古老的湖。它形成于两千五百万年前,亚洲板块从一系列断层分离出来,即原始大陆板块中各各板块分离时期,贝加尔湖谷下陷裂开,最终填满了水创造了世界上最深的湖
贝加尔湖的最大深度为1640米,如果在这个湖底最深点把世界上4幢最高的建筑物一幢一幢地叠起来,第4幢屋顶上的电视天线杆仍然在湖面以下58米处。尽管湖水非常清澈,人们能看到湖面下40米的东西。但这4幢建筑物还是人们的视程之外。
贝加尔湖容纳世界淡水的五分之一,是许多罕见的野生生物之家
贝加尔湖是由地壳的深裂谷或积水而形成的。大约有300多条河流注入该湖泊,但只有一条河---安加拉河从湖泊流出。在冬季,湖水冻结至1米以上的深度,历时4-5个月。但是,湖内深处的温度一直保持不变,约3.5摄氏度。
在贝加尔湖里生活着世界上唯一的淡水海豹。冬季时,海豹在冰中咬开洞口来呼吸,由于海豹一般是生活在海水中的,人们曾认为贝加尔湖由一条地下隧道与大西洋相连。实际上,海豹可能是在最后一次冰期中逆河而上来到贝加尔湖的。
贝加尔湖位于西伯利亚南部,邻近蒙古国,是东亚地区不少民族的发源地。中国史称北海。
