库姆塔格沙漠风沙地貌区划

摘要/Abstract

摘要： 近年来,中国沙漠科学工作者对库姆塔格沙漠进行了系统的考察与研究。作为风沙地貌研究工作的初步总结,笔者尝试该沙漠风沙地貌区划研究工作。在风沙地貌地域分异规律理论的指导下,提出综合分析与主导因素相结合、发生学以及多级序的区划原则,采用自上而下的顺序划分法,选择主导分异因素,提出了库姆塔格沙漠风沙地貌的两级区划系统。首先,根据下伏地貌的成因类型划出一级分区(风沙地貌区)。其次,根据沙丘形态特征划分出二级分区(风沙地貌亚区)。提出的区划方案将库姆塔格沙漠划分为7个风沙地貌区、23个风沙地貌亚区,并对各区和亚区的风沙地貌特征作了简要的介绍。

Abstract: The Kumtagh Desert of China has received considerable field investigation and study in the last few years. An attempt is made in the present paper to provide an aeolian geomorphological regionalization as a preliminary summarization of the research in aeolian geomorphology of the Kumtagh Desert. With the theoretical guidance of regional differentiation regularity in geomorphology, the principles followed include genetic similarity, multi-order division, and a combination of comprehensive analysis and dominant factors, and a two-order regionalization system is presented by means of top-down division order and selecting leading factors. The regions of the first order (geomorphological regions) are divided in terms of causes of the underlying landforms, and the regions of the second order (geomorphological sub-regions) are divided in terms of the aeolian morphology of landforms. The present scheme divides the aeolian geomorphology of the Kumtagh Desert into seven regions and 23 sub-regions. The characteristics of each region and sub-regions are described briefly.

Key words: aeolian geomorphology, regional aeolian geomorphology, geomorphological regionalization
