摘要:
提要: 中国月球数字地质图的编制是利用嫦娥一号、嫦娥二号月球科学探测数据和其他已有月球地质资料与研究成果, 通过对月球岩石成分、地质构造和形成时代等要素的研究, 应用ArcGIS平台编制1∶250万月球地质图, 并建立数字地质图空间数据库。本文通过对月球典型地区地质图的编制与研究, 制定了月球数字地质图的编图方案、流程与图示图例, 建立了Geodatabase空间数据库, 为有效地对数字地质图进行更新与管理, 开展月球地质综合研究、编制全月球地质图及未来开展其他天体的地质编图工作奠定了基础。通过地质图编制与大量月球资料的综合集成研究, 对月球形成与构造演化进行了初步的探讨。
Abstract:
Abstract: The compilation of the Lunar Digital Geological Map was based on the scientific exploration data obtained by Chang’E-1 and Chang’E-2 and other lunar geological data as well as research?results. According to the material compositions, structure elements and the information of geochronology of the Moon, the authors compiled the Lunar Geological Map at a scale of 1∶2500000 and established spatial database by using the ArcGIS platform. The authors developed a mapping programs, processes and legends for the Lunar Digital Geological Map, and established a spatial database based on Geodatabase model by compiling and investigating geological map of the typical region, which can effectively update and manage the Digital Geological Map and thus lay the foundation for the geological comprehensive study of the Moon, the geological mapping of the whole Moon, and also the geological mapping of other celestial bodies in the future. This paper also deals with the tectonic evolution of the moon on the basis of summarizing the compilation of the Lunar Digital Geological Map and comprehensive research on a large number of lunar geological data.
