我国海洋地质知识体系DIKW模型及其规模估计与增长研究

Study on DIKW instance model and size of the marine geological knowledge hierarchy in China

我国的海洋地质工作起步较晚,缺少对学科发展的整体评价。采用DIKW(Data-Information-KnowledgeWisdom,DIKW)概念模型,阐述了我国海洋地质知识体系的构成及关联领域,归纳并提出了可用于统一描述海洋地质知识体系的实例模型;应用信息计量学方法,对我国海洋地质知识体系的规模进行了初步估计,原始数据超过10万件,研究论文超过1万篇;依据案例研究的结果,分析了1979—2017年我国海洋地质数据-信息-知识的同步增长情况,在经历15 a(1980—1995年)的缓慢增长阶段后,我国海洋地质工作进入了一个由基础研究向专业调查转变的快速增长时期。

In China, the marine geological survey has started late and lacked an overall evaluation for the discipline development. Utilizing DIKW （Data-Information-Knowledge-Wisdom, DIKW） conceptual model, the author expounded the composition and associated fields of the marine geological knowledge hierarchy in China, and put forward an example model for describing the system. Through the informetrics method, the author evaluated preliminarily the size of the marine geological knowledge system, and the results show that there are the 100,000 raw data and more than 10,000 research articles in the system. According to the study results of this example, the author analyzed the simultaneous growth of the marine geological data-information-knowledge from 1979 to 2017. After 15 years′（1980 to 1995） sluggish growth, the marine geological work in china has entered a rapid growth period of the transformation from fundamental research to professional investigation.
