摘　　要：PDS行星数据系统是存储和发布美国NASA所有行星探测数据的信息平台,是行星科学研究和发展的重要基础。PDS的标准、存储结构和数据处理流程是由NASA协同多个行星研究所和多个大学共同制定,为行星数据的存储和应用提供重要保障。由此,对于这些标准的深入研究是了解和应用这些数据的基础。本文从PDS建立的科学意义,及最原始建立的科学目标和科学任务出发,从底层分析PDS数据文档存储结构,并结合项目组实际使用经验给出最便捷、最实用的数据使用方式及科学软件工具的实际经验。最后,本文以实际数据为例给出了PDS详细的使用流程以及最终处理成果,并在最后提出了PDS的未来发展建议。希望能为我国行星科学家及行星数据库系统平台的建设提供重要参考。同时,PDS行星数据库系统平台作为更广阔的数据系统平台,它也为中国行星科学甚至地球科学建设提供重要参考依据。Planetary Data System（PDS）,aplatform to archive and distribute all planetary data sets by NASA,is fundamental to research and developments on planetary science.Standards,data organizations,processing program of the PDS,which were jointly established by planetary institutions and universities,have become a footstone for storage and application of THE PDS.Accordingly,the profound research on these standards is a basis of understanding and applying these data sets.Starting from the PDS science significance and its initial goals and missions,this study analyzes especially PDS storage structures and then presents the most convenient and practical data application methods and practical experiences regarding to usage of software and tools.At last,this study illustrates the procedure of data processing and results through a real example and proposes consideration for future developments of the PDS,in hope of providing an important reference for Chinese planetary scientists to construct the similar planetary data system platform.Meanwhile,the PDS,as a more comprehensive data system platform,will provide an important basis for construction of China＇s Earth science data system.
