摘要:

雅丹地貌是火星表面分布最广泛的风成地貌类型之一,蕴含着丰富的火星环境及火星表面演化历史信息。本研究基于HiRISE、CTX等高分辨率遥感影像,对火星全球雅丹地貌进行形态识别与系统分析,挖掘其蕴含的火星环境信息及地貌学意义。结果表明:火星雅丹类型复杂多样,采用形貌学分类方法并综合考虑形态细节,共划分出17种火星雅丹,特别是存在地球上罕见的双向型雅丹和V型雅丹;火星雅丹形态参数概率累积曲线均出现断点和转折,表明其存在不同群组特征,雅丹规模差异显著;火星雅丹各形态参数间存在一定相关性,但这种相关关系与地球雅丹之间存在差异,指示火星雅丹可能存在多种演化模式。火星雅丹整体规模大于地球,但各类型雅丹长宽比与地球较为相似,说明无论长宽如何变化,形成某种特定类型雅丹的长宽比较为一致。火星雅丹长宽比以小于2∶1以及大于6∶1为主,指示火星雅丹可能并不处于发育的成熟阶段。

Abstract:

Yardang landform is one of the most widely distributed aeolian landforms on Mars, which contains abundant information about the Martian environment and the evolution history of the Martian surface. This study identifies and systematically analyzes the morphological characteristics of the global yardang landforms on Mars, and explores the Martian environmental information and geomorphological significance contained in the Martian yardangs by HiRISE images, CTX images, and other multi-source remote sensing images. The results show that the Martian yardang types are complex and diverse. By using the morphological classification methods and considering the morphological details, 17 types of yardangs on Mars are identified, among which bidirectional yardangs and V-shaped yardangs are rarely found on Earth. The probability cumulative curves of the morphological parameters of the yardangs on Mars all exhibit breakpoints and turning points, indicating that there are different group characteristics in the morphological parameters of the yardangs, and there is a significant difference in the scale of the yardangs. Although there is a certain correlation between the morphological parameters of the Mars yardang, this correlation differs from that of yardangs on Earth, indicating that there may be multiple evolution modes of the Martian yardang. The overall size of the Martian yadangs is larger than that of the Earth, but the length-width ratio of the Yardangs on Mars is similar to that of the Earth, indicating that the length-width ratio of a specific type of yardang is consistent regardless of changes in length and width. The length-to-width ratio of Martian yardangs are mainly less than 2∶1 and greater than 6∶1, indicating that Martian yardangs may not be in the mature stage of development.
