摘　　要：综合多源遥感数据识别提取月球正面南北纬50°之间的线性构造,重点分析月岭和月溪的影像特征、分布规律和时空关系,结合月海沉降模型分析两者的成因机制,结合地形和重力场数据预测影响月岭类型的因素。研究表明,在质量瘤盆地,月岭和月溪存在明显的时空关系和构造成因联系,两者主要由月海沉降产生的局部应力引起,前月海时期盆地的均衡状态和月海充填的几何形状可能影响了月岭的分布类型。Lunar lineaments within 50° north and south latitudes of lunar nearside have been mapped based on the Chang＇E-1 CCD image data and other lunar scientific data.Landform features and spatial distribution of mare ridges and lunar grabens have been analyzed.Mare subsidence model was used to analyze the genetic mechanism of mare ridges and lunar grabens,and Digital Elevation Model（DEM） data and gravity data were used to predict the distribution of mare ridges.In mascon basins,the genetic connection between mare ridges and lunar grabens was mainly caused by the local stress of mare subsidence.The geometry of the load and the premare isostatic state of the basin probably influenced the distribution of concentric and radial mare ridges.
