摘　　要：长期以来,最初依据月表反照率建立的月陆、月海二分法一直主导着人们对于月球构造格架的基本认识,然而自20世纪末以来的各种月球探测数据均表明,南极艾肯盆地作为月球上最大的撞击盆地不仅占据了月表很大的面积,而且有不同于月陆和月海的性质及演化过程.本文通过综合研究月球典型的地球物理、地球化学以及地形特征,初步确定了月球的全球构造格架是一个既有横向表面延伸又有纵向深部延伸的三元结构,包含三个月球大地构造单元,分别是主要覆盖正面风暴洋及周围月海盆地区域的月海构造域、主要覆盖背面高地的月陆构造域以及位于南极艾肯盆地的南极艾肯盆地构造域.For a long time,the land-mare dichotomy based on lunar albedo has dominated our general sense of the lunar global geotectonic framework.However,lunar exploration data since the end of the last century shows that the South Pole-Aitken basin,which is the largest impact basin on the Moon,not only occupies a large region of the Moon but also differs from highland and mare in properties and evolution processes.Based on the study of the typical characteristics of lunar geophysics,geochemistry and topography,ageotectonic framework of ternary pattern is proposed here.The three units extend both on the horizontal surface and in the vertical direction,including the mare tectonic domain that mainly covers the Procellarum and its neighboring mare basins,the highland tectonic domain that mainly covers the highland on the farside,and the South Pole-Aitken basin tectonic domain that is mainly occupied by the great South Pole-Aitken basin.
