【摘要】 作者利用亚洲、部分欧洲及西太平洋58个数字地震台站以及国内34个数字地震台站，从中选取出范围为42~0E-170~0E,24~0S-66~0N，时间跨度从1982—2003．3年间的14000多条地震记录。在对庞大的原始数据进行了筛选，经处理后得到原始记录、频散反演(混合频散反演和纯路径频散反演)、速度_深度反演和地震信息共四部分数据记录及其成图。为对这些海量数据进行合理有效管理，作者采用发展较成熟的开发平台和软件设计方法，开发一个独立、功能完善的“中国及相邻陆域海域面波层析成像数据库系统”，对研究地球深部过程，对了解中国及邻区边缘海岩石圈／软流圈形成及演化，了解中国大陆形成及演化以及地表构造与深部结构的关系都具有极大帮助和重要的意义。 本文选题来源于国家自然科学基金重点项目(49734150)《中国及邻区地球内部各圈层三维结构及动力学研究》、国家自然科学基金重点项目(40234047)《东亚西太平洋边缘海岩石圈、软流圈细结构及深部过程研究》和国土资源部专项项目(20001010)《中国岩石圈三维结构研究》。更多还原

【Abstract】 In this paper, we select 14000 seismic records in the rang of 420E-1700E,240S-660N from 1982 to 2003 in the 58 digital seismic stations of Asia, Part of Europe and western Pacific and 34 digital seismic stations of China, In order to manage these complicated data, We gain four parts of data records and their maps of initial records, dispersion inversion ( including mixed dispersion and pure path dispersion ), inversion of velocity versus depth and seismic information from selected huge of initial data. Based on development platform and the software designing, we develop a self-governed and perfect Database System for Surface wave tomography in china and its adjacent land and sea areas. This database system is helpful and important for probing into the deep earth, the form and evolvement of lithosphere/ asthenosphere , the form and evolvement and the relation of surface structure and deep structure of Chinese continent.This dissertation is funded by two projects of National Natural Science Fundation of China numbered by 49734150 and 40234047, which are The researching into 3-D structure and geodynamics of interior circular layer in china and its adjacence, The researching into the detail structure of lithosphere and asthenosphere and deep progress in east Asia and western Pacific. Also this dissertation is funded by the special project from the Ministry of Land and Resources numbered by 20001010 titled The researching into lithospheric 3-D structure in china.更多还原
