    摘要:

    在地球历史上湖泊沉积大规模的发育或缺失,都和一定的构造背景和气候环境条件相关。本文依据我国晚新生代以来,湖泊沉积时空规模和分布的变化,来探讨我国大环境的变迁过程。上新世和早更新世我国西部存在许多大湖泊,发育巨厚的湖泊沉积,而东部分布的范围很局限,造成这种情况的原因,除了构造运动的差别外,当时大气环流的形势与今不同,西部的气候条件相当湿润。中-晚更新世西部的大湖大都萎缩,甚至消失,东部却表现出大湖增加的趋势,这显然与青藏高原的迅速隆起、东亚季风的加强有关。末次冰期以来,对应于冰期、间冰期的气候变化,不同气候带湖泊的响应差异颇大,既表现出区域环境的特点,也有全球变化事件的反映。

    Abstract:

    The development in large scale of lacustrine sediments or their deficiency in geologic history of the earth is closely related to the definite geostructural background and climatic conditions. According to the temporal-spatial distribution of lacustrine deposits since late-cenozoic, the evolutionary processes of macroenvironments are discussed in this paper. There exist a great number of large lakes in West China, with a thick pliocene and Early pleistocene deposits in the lakes, whereas only limited lake sediments were found in East China. This situation was resulted from the different structual movement and air circulation, with a rather humid climate in West China at that time. In mid-late Pleistocene, most of large lakes in West China shrunk quickly or even disappeared, while the tendancy of increasing and expanding of lake occurred in East China, which was evidently related to the rapid uplifting of Qingzhang Plateau and strengthening of East Asian monsoon. The lake response to in climatic zones giaciation and interglaciation since Last glacial age shows rel-ativeiy obvious differentiation indicating the influences of global, regional and local ronments respectively.
