摘　　要：除了极少数非常陡峭的山脉与撞击坑和火山通道的峭壁外,整个月球表面几乎都被一层厚度不等的月尘、岩屑和岩块的混合堆积物即月壤所覆盖。由于月球无大气层等特殊环境,太阳光长驱直入,太阳风粒子直接注入到月壤细小颗粒上使月壤中富含稀有气体等太阳风粒子组分。本文在系统阐述月壤的形成过程与形成机制的基础上,分析了月壤中稀有气体的来源及其浓度与月壤的成熟度、月壤颗粒大小、月壤矿物组成和化学成分的相关关系,进而利用已有的探测数据和分析结果,对月壤中氦 3资源的开发利用前景进行了初步评估。With the exception of a few extremely cliffed mountains and impact craters as well as the cliffy walls of volcanic channels, the whole lunar surface is almost covered by the mixed accumulates of lunar soil, debris and fragments , differing in thickness, which are referred to as the lunar regolith. Since there is no atmosphere or other special environments on the Moon, the solar rays can directly reach the lunar surface and the solar wind particles can find their way directly into the small grains of lunar soil, making the lunar regolith become enriched in noble gases and other solar wind-interplanted particle components. This paper systematically deciphers the process and mechanism of formation of the lunar regolith, and, on this basis, analyzes the relations between the source and concentrations of noble gases in the lunar regolith and its maturity, grain size, mineral composition and chemical composition. Furthermore, in the light of the surveyed data and analytical results available, a preliminary evaluation has been made on the development and utilization prospect of helium-3 resource in the lunar regolith.
