摘要:
为了解国际海洋地质领域研究的总体状况和研究热点,根据国际重要战略规划、行动及海洋地质领域发表的科技论文,采用战略规划解读及文献计量学的方法对海洋地质领域发展态势进行分析,基于研究结果得出中国海洋地质领域的研究与布局启示。分析结果表明,从20世纪90年代以来海洋地质领域发表科技论文数量看,保持了波动式增长趋势变化,海洋发达国家美、法、英等国的研究实力较强。近年来,海洋地质领域研究呈现明显的跨学科特征,其中大洋中脊、海底沉积物及矿物地球化学特征研究是海洋地质领域研究的核心,深海采矿、板块俯冲过程、地震引发的海啸备受关注,海底热液及采矿相关的环境、生物多样性、新物种等的跨学科研究成为深海地质研究的新兴趋势。
Abstract:According to the international important strategic planning, operations and published scientific papers in the field of marine geology, based on reading strategy planning and the method of literature metrology analysis of marine geology development, combined with the study results, the layout and research enlightenment of marine geology in China are obtained to understand the international overall status and the research hot issue in the research of marine geology.The analysis results show that the number of scientific papers published in the field of marine geology has maintained a fluctuating growth trend since the 1990s, and the marine developed countries such as the United States, France and the United Kingdom keep a powerful researching level.In recent years, the marine geology research exhibits obvious interdisciplinary characteristics.The mid-ocean ridge, submarine sediment and mineral geochemistry are the core of the marine geology research.Much attention has been paid to deep sea mining, plate subduction process and tsunami triggered by an earthquake.The interdisciplinary research of seafloor hydrothermal fluid and mining-related environment and biodiversity becomes the emerging trend in the field of deep-sea geology.
