全月球形貌类型划分方法研究

Analysis on morphological characteristics and dividing morphological units for lunar surface, study and compilation of lunar morphological maps are one of foundational objects on lunar exploration project and lunar scientific research. Comparing with lunar digital geology, research on lunar morphological characteristics need to be more systematically and deep carried out. Based on multi-source remote sensing data, DEM data, photos, geological map obtained from lunar domestic and foreign exploration projects, in this study, spatial differentiation of lunar morphological characteristics is taken as the main research object, the contents include: selecting and setting up a comprehensive index system, which can systematically describe lunar morphological characteristics such as morphology, genesis, composition etc., studying numerical methods of these indicators from RS and DEM data etc.; building classification method combining with morphology and composition of lunar appearance characteristics and types; building intelligent identification and extraction method for full lunar appearance characteristics and types, and obtaining lunar digital morphological type maps; studying regionalization scheme and method for lunar appearance characteristics, obtaining lunar multi-class morphological feature regionalization maps, compiling 1:2 500 000 lunar digital morphological atlas; Analysis on spatial differentiation characteristics based on full moon surface and different partitions, and exploring formation mechanism and evolution process of lunar morphological features of different partitions, etc. The study can provide the basis and background for studying the formation of lunar evolution, future resource exploitation and utilization of our country.

月球形貌特征分析及单元划分、月球形貌图的研究与编制是月球探测工程及月球科学探索的基础性科学目标之一。与月球数字地质等研究相比，月球形貌研究需要更系统性地深入挖掘。基于国内外已获得对月球探测的多源遥感数据、DEM数据、照片、地质图等，本项目以月表形貌空间分异特征为主要研究对象，遴选并建立一套综合描述月球形态、成因、物质组成等形貌特征的指标体系，研究这些指标的获取方法；建立形态与物质组成相结合的全月球形貌特征及类型的分类方法；构建基于智能化的全月球形貌特征及类型的识别和提取方法，获得全月球数字形貌类型图；研究全月球形貌特征的分区方案和方法，获取全月球多级形貌特征分区图，示范编制月球1:250万数字形貌图集；研究全月球及不同分区的形貌特征空间分异特征，探讨不同分区的形貌特征形成机制及演化过程等。该研究可为探讨月球的形成演化过程提供基础，为我国的探月、登月工程以及月球资源的开发利用提供本底。
