摘　　要：撞击坑是月表的主要地貌形态，按普通碗状型、中心隆起型、平底型及同心圆型4种类型描述“第一幅月面图像”上月表撞击坑的形态特征。应用遥感专业图像处理软件，结合白赛尔大地主题反算法，实现撞击坑分布及直径信息提取。研究发现，研究区域的撞击坑直径主要集中在300～700m。而且撞击坑空间分布不均匀，直径越小，分布越密集。Craters are one of the major features on lunar surface, it is important to study their characteristics. The craters identified from the first image Chang＇e- 1 can be classified into 4 types, such as the normal, central mound, flat-bottomed and concentric craters. The morphological characteristics of different craters are described. Making using of remote sensing professional software, the diameter information and spatial distribution of the craters were extracted with Bessel geodetic algorithm. The results showed that craters＇ diameter are mainly concentrated between 300 and 700 meters. Their spatial distribution is inhomogeneous, and its densest degree rises with diameter decreasing.
