中国地质大学肖龙教授团队联合香港大学、澳门科技大学等机构，通过分析月壤成熟度、暴露年龄和雷达探测数据，成功重建了嫦娥五号着陆区月壤的完整演化历史[1]。研究表明，该地区的月壤形成过程始于约20.3亿年前的大规模玄武岩岩浆喷发，之后约20亿年至2.4亿年间，太阳系内小型天体的撞击作用持续改造着月壤结构[1]。
研究团队对表层至65厘米深度的月壤进行了完整剖面分析，发现月壤呈现三层结构特征[1]。其中顶部0-3厘米区域成熟度较高；中部3-23厘米成熟度中等；底部23-65厘米成熟度极低[1]。月壤成熟度的分布并非线性递减，撞击作用的影响深度仅限在23厘米以内[1]。这一发现为后续月球探测与资源开发提供了关键工程参数，相关成果已发表于《空间科学与技术》国际期刊[1]。
A research team led by Professor Xiao Long from China University of Geosciences, in collaboration with institutions including the University of Hong Kong and Macau University of Science and Technology, has reconstructed the complete evolutionary history of lunar soil at the Chang'e-5 landing site [1]. By analyzing soil maturity, exposure ages, and radar detection data, the researchers traced the soil formation process from a major basaltic eruption approximately 2.03 billion years ago to the present [1]. The study revealed that continuous small-body impacts occurred within the solar system between approximately 2 billion and 240 million years ago [1].
The investigation established a complete stratigraphic profile extending from the surface to a depth of 65 centimeters [1]. The lunar soil exhibits a three-layer structure with varying maturity levels: the upper layer (0-3 centimeters) shows relatively high maturity, the middle section (3-23 centimeters) displays moderate maturity, and the bottom layer (23-65 centimeters) exhibits extremely low maturity [1]. Notably, the effects of impact processes are limited to depths of only 23 centimeters or less [1]. The findings have been published in the international journal Space Science and Technology and provide critical engineering parameters for subsequent lunar exploration and resource development [1].
