艾比湖地处亚欧大陆腹地,属典型的封闭型干涸尾闾湖,本文通过对灌草丛沙堆形态特征、沙堆类型、分布规律和沉积结构的野外考察,选取若干典型灌草丛沙堆剖面进行系统采样测试分析,根据艾比湖流域典型剖面沉积物粒度特征,揭示风沙层粒度记录的降水或相对湿度变化显示明显的区域特征。 Aibi Lake is located in the hinterland of the Eurasian continent, is a typical closed-type dried-up Lake Village, this paper through the grass shrubs morphological characteristics, sandbank type, distribution and sedimentary structure of the field investigation, select a number of typical shrubs According to the sediment grain size characteristics of the typical section in the Aibi Lake basin, it is revealed that the precipitation or relative humidity in the sandstorm grain size shows obvious regional characteristics.
