  • 死海是一个内陆盐湖，在死海里，由于盐分很高，鱼儿和其他水生物都难以生存，水中只有​细菌和绿藻，没有其它生物；岸边及周围地区也没有花草生长，所以人们称它为“死海”。

Distribution of salt lakes in the World

The global distribution of salt lakes can be basically divided into two salt lake belts and one salt lake zone. They are the northern hemisphere belt, the southern hemisphere belt and the equatorial zone. The northern hemisphere belt is composed of many famous salt lakes including Lake Chad in North Africa, Dead Sea in west Asia, Lake Urmia in Iran, Qarhan in China, and the Great salt lake in US. However, Lake Chad is rapidly shrinking, and will possibly disappear in 20 years. Major salt lakes in southern hemisphere belt are Mulikaoutur and Lefroy in Australia, Salinas in Peru, Atacama in Chile, Dililali in Argentina and Uyuni in Bolivia and so on. The equatorial zone consists of salt lakes located in the East African rift zone of Uganda, Kenya and Tanzania. (Data source: Qinghai saline lake research institute)

salt lake Q & A

Through a period of study, we've already got to know a lot on salt lakes. So let's speak out what you know now.


  • Question:

    盐湖是怎么形成的?
    Apr. 13, 2009


    • Answer:

      流入湖水中河流有大量盐分矿物质，湖水不断蒸发，水中盐分浓度不断升高，形成盐湖。

  • Question:

    提问：什么是盐湖？青海湖是不是盐湖？
    Apr. 11, 2009


    • Answer:

      Question:
      回答:青海湖不是盐湖，它只是咸水湖。
      由于我们中国的盐湖比较多，所以我们中国对盐湖的定义是：湖里面的水的含盐度为(50​​克/升)的卤水湖或有盐类物质沉积的那些湖泊。而那些已经没有盐水但在盐类沉积的孔​隙​间还有卤水的就叫“干盐湖”。这个知识是我爸爸告诉我的。

  • Question:

    你们知识盐的分类吗?
    Apr. 11, 2009


    • Answer:

      哈哈,组长,这个问题问的有点怪啊!
      不同的角度,就有不同有分法啊.
      从原料来源上分,就有井盐、海盐、湖盐、岩盐等。
      从用途上分可以分为生活用盐、工业用盐、农业用盐、医药用盐等。
      也可以从生产方法上分呢。

  • Question:

    提问:盐花是如何形成的?为什么有的盐花发黄,有的盐花很白呢?
    Apr. 11, 2009


    • Answer:

      盐花的颜色不同,是因为盐水里面的东西不一样,我找了一下资料,如果盐水里有泥时,盐​花是灰色的，含氧化铁时,盐花会发红，含有机质时是黑褐色，如果有其他矿物质时还会形​成青色，蓝色或紫色的盐花.我们青海著名的"青盐"里面就有矿物质。不知道我的回答你​满意吗？
