吉兰泰盐湖的形成,发育和演化

吉兰泰盐湖的演化过程有着明显的阶段性。根据地貌结构、沉积特征、盐化学特征以及人为活动对盐湖的影响,可以认为:全新世以来,吉兰泰盐湖演化大致经历了五个发展阶段:早全新世的咸水湖、中全新世早期的硫酸盐型盐湖、中全新世晚期的硫酸盐-氯化物型盐湖、晚全新世的氯化物型盐湖和现代干盐湖。现今由于人为活动的影响,盐湖正向沙下盐湖转化。

FORMATION, DEVELOPMENT AND EVOLUTION OF JILANTAI SALT-LAKE, INNER MONGLIA

There are obvious stages in Jilantai Salt-lake's evolution. From the area's geomorphic structure and characteristics, the stratigraphical and sedimentary characteristics of Holocene series in the salt-lake, feature of salt chemistry and tremendous influence on the salt-lake environment by human activities, we can divide the evolution of Jilantai Salt-lake since Early Holocene epoch into five transitional phases. They are: Saline-water-lake phase of sulphates type in early interval of Middle Holocene epoch, salt-lake phase of sulphate-chloride type in later interval of Middle Holocene epoch, salt-lake phase of chloride type in Late Holocene epoch and dry salt-lake phases at present. Today, the salt-lake is being transformed from dry salt-lake bed into sand-buried lake bed beca use of irrational human activities which have caused sands to be deflated from the ground.
