中国海陆1∶500万地质地球物理系列图与数据库研制

60年来,利用我国各种地质地球物理数据,结合野外考察,运用块体构造学说编制了中国海陆1∶500万地质地球物理系列图。其从理论基础、方法技术上,实现中国海陆地质地球物理数据的融合;系统地反映出我国海陆基础地质调查与研究现状及大地构造格架;同时展示古生代以来中国海陆各块体的发育、运移、拼接和联合大陆的形成过程,以及印支运动后中国大陆由"东高西低"转为目前"西高东低"的演化规律。另外,通过系列图件的编制与建库,为我国矿产资源勘探及资源环境效应研究提供了基础图件数据。

Serial Maps Compilation and Database Construction of Geology and Geophysics on China Seas and Land on the Scale of 1:5 000 000

Geological map, as an efficient tool to present and summarize geological survey results, is a kind of geological information indispensable for economic and social development, and has attracted great attention from the government and the public all over the world. Qingdao Institute of Marine Geology has been complicating the serial maps of geology and geophysics on China Seas and Land on the scale of 1:5M since 2008. It is important to compile a piece of map including Chinese mainland and China Seas and the adjacent land and sea area. The serial maps compilation was under guidance of block tectonics, and based on various data and survey results of geology and geophysics on China seas and land over the past sixty years. The compilation has three main purposes: realizing the splice that includes theoretical basis, technology and method of maps of geology and geophysics on China seas and land; reflecting the status of survey and research of basic geology and tectonic framework of the study area; and exhibiting the growth, development and collision of different blocks and the formation of Pangea on China seas and land since Paleozoic, revealing emphatically the evaluation process of Chinese mainland that from "higher in the east, lower in the west" to "higher in the west, lower in the east" since the Indo-China movement. The serial maps can provide service to geological work deployment which would be helpful for the policy-making body. Meanwhile, the serial maps can also be used as a basic map for mineral resources exploration and resources and environment studies. And, the methods we used in the compilation of the serial maps are introduced as a new try to solve the problems we had met.
