摘    要:-全球变化研究是国际上地球系统综合研究的重大跨学科研究领域。随着全球环境问题的日益突出,国际上先后组织发起了全球环境变化研究的四大科学计划WCRP、IGBP、IHDP、DIVERSITAS及其组成的地球系统科学联盟ESSP,开展对全球变化和地球系统科学的研究。当前,全球变化问题不仅是科学界关注和研究的问题,也是政治界、经济界都关注的重大问题。 科技文献能够反映科学前沿的发展动态。对SCIE和SSCI数据库收录的全球变化研究文献进行统计,从文献计量学的角度,分析国际全球变化研究领域的发展态势,了解中国全球变化研究的国际影响力。可以看出:国际上全球变化研究的论文数量一直呈增长趋势,以地球科学多学科、生态学、环境科学、自然地理学、植物学等学科领域为主。中国自2000年以来在该领域的发文数量增长较快,特别是中国科学院的发文量已进入国际前列,但中国在该研究领域尚缺少高影响力的论文。

Abstract:Some research events, chacteristics and causes of deep sea cold-water carbonate mounds are reviewed, and prelimary results of cabon and oxygen isotope values are reported from the IODP 307 hole 1317E in this paper. There are at least nine social events in cold-water coral and carbonate mound development that have taken place for the recent years, which stimulates the research of the deep sea cold-water organism. Cold-water carbonate mounds are of concentration on continenatal slopes in ocean, with variable shapes and sizes, and they are mainly constructed by cold-water tree corals. In general, cold-water carbonate mounds could be triggered by either geofluid, or mcrio biota, or submarine current, but few evidences on geofluid or mcrio biota have been found in the IODP 307 sites, Porcupine Seabight, west off the Ireland shelf. According to primary results from the IODP 307 hole 1317E, two excursion events (I & II) of carbon and oxygen isotope values are recognized in the Middle Pleiocene-Lower Pleistocene intervals of the tree coral mound. Both extremely negative excursion of carbon isotope values and strongly positive excursion of oxygen isotope values (Event I) happened at the base of the mound, which indicates a linkage to the initiation of the mound. An extremely postive excursion of carbon isotope values (Event II) can be recognized from the sample 1317E-3-6w-50-52. The isotope excursion events, especially Event I imply that the paleoceanographic climate has greatly changed since the initial carbonate mound, which is to some extent related to the extremely properous Arctic ice sheet.
Keywords:Cold-water coral  Carbonate mound  Deep sea  IODP  Carbon isotope  Excursion event
