The Moscoviense Basin is one of the large multi-ring structure impact basins located in the northwest of the far side of the Moon.However,the distribution of the multi-ring does not follow concentric ring structure and the internal northeastern peak ring is missing.It has been the focus of scholars because of its special geographical location and atypical multi-ring structure.Ideal three rings of the Moscoviense Basin are presented based on the elaborate analysis of Wide-Angel Camera (WAC) image data,Multiband Imager (MI) data and Lunar Orbiter Laser Altimetry (LOLA) data,and these multi-ring structures are explained in detail.The diameter of ideal peak ring is 192 km,but its northeastern part is missing.The shape of intact ideal middle ring is roughly oval,whose long and short axis are about 451 and 410 km in diameter respectively.The ideal outer ring's diameter is 677.5 km.The center points of ideal peak ring,middle ring and outer ring align from southwest to northeast,approximately 30° to the horizon.The space between ideal peak ring,middle ring and outer ring are 27.36 and 45.77 km respectively.Meanwhile,a representation method which integrates micro-topographic and macro-topographic factors is presented.These integrated characteristic values are used to reinterpret the multi-ring structure and verify the distribution of the three ideal ring structure of Moscoviense Basin.Besides,the paper analyzes the types,features and genesis of ring-shaped and liner structure of the basin,in particular,the topography of internal Titov and Komarov crater.It completes a tectonic outline map of the Moscoviense Basin based on its linear structure,ring structure,and multi-ring basin.With analysis of geomorphology and structural characteristics of Moscoviense Basin,the paper explores its tectonic evolution process and provides a theoretical reference for early tectonic development history of the Moon.%莫斯科盆地是位于背月面西北部的大型多环撞击盆地.该盆地环状结构呈非同心环状分布,且内部东北部峰环缺失,因其特殊的地理位置以及非典型的环状结构引起了相当多学者的关注.通过WAC和MI影像数据和LOLA地形数据等多源数据的综合分析,确定了莫斯科盆地的理想3环结构:盆地理想峰环东北部缺失,所在位置环的直径约为192 km;理想中环结构完整,形状较为规则,近似椭圆形,长轴直径约为451 km,短轴直径约为410km;理想外环直径约677.5 km.理想峰环、中环和外环的中心近似沿西南—东北走向与水平方向成30°角直线排列,中环和外环与内峰环距离分别为27.36、45.77 km.提出了融合微观地形因子和宏观地形因子的形貌综合特征表示法,依据该综合特征值重新解译莫斯科盆地的多环构造,验证了理想3环结构的分布.除盆地构造外,进一步对盆地内的环形和线性构造的类别、特征和成因进行了详细剖析,特别是盆地内部Titov和Komarov月坑形貌构造的分析.同时完成了以线性构造、环形构造以及多环盆地建造为主体要素的莫斯科盆地区域构造图的编制.在对莫斯科盆地的形貌与构造特征进行深入分析的基础上,探究该多环盆地区域的构造形成演化,为月球早期的构造演化研究提供理论参考.
