中国自2003年发表第一篇生态化学计量学研究论文以来,相关研究快速发展并取得了一系列重要研究成果。通过对20032016年中国知网(CNKI)总库中文核心期刊收录的960篇及Web of Science中319篇关于对中国各研究区生态化学计量学的研究文献统计,结合CitespaceⅢ软件分析与对比了这些研究文献间的引用关系和知识图谱等,以探讨中国生态化学计量学研究的热点与发展趋势。研究结果表明,中国生态化学计量学研究主要围绕 生态化学计量、化学计量、碳氮比、碳氮磷和土壤养分、土壤有机碳、氮沉降等关键词展开;其中,王维奇、曾从盛、仝川等是主要的发文作者。中国科学院地理科学与资源研究所、福建师范大学和西北农林科技大学等高校、科学研究院在中国常绿阔叶林、荒漠草原、黄土高原及闽江河口等地区进行了深入研究与探索,而国外亚利桑那州大学、佐治亚大学等也对中国各区域生态化学计量学研究密切关注。同时,在国家自然科学基金(NSFC)的持续支持下,结合新研究方法和技术,围绕元素循环、地球变化空间、时间分布特征及陆地和水生生态系统的限制因素成为其研究热点。目前,国内研究区域已延伸到青藏高原高寒草甸、热带和亚热带阔叶林等区域,主要以陆地生态系统为主,而国际上关注更多的是水生生态系统如fresh water、climatenutrient limitation等相关研究,今后,生态化学计量学的研究将侧重于气候变化和营养物动态平衡模型、营养元素(K,Na,Ca,S)对生态化学计量和基因的影响等研究方面。
英文摘要:
A great progress has been achieved in ecological stoichiometry since the first paper published in 2003. Based on the articles collected by the core journals of China national knowledge infrastructure(CNKI) and Web of Science with Chinese ecological stoichiometry during 2003 - 2016,the reference relationship and knowledge maps of the papers have been analyzed by Citespace III,and to further discuss the hotspots and developing trends of Chinese ecological stoichiometry. The results showed that the study of Chinese ecological stoichiometry is focused on ecological stoichiometry,carbon-nitrogen ratio,soil nutrient and organic carbon and nitrogen deposition, and has achieved abundant achievement. Wang,Zeng and Tong have published a large number of research papers on ecological stoichiometry. Many Chinese academy of sciences and universities have deeply studied and explored in the area of evergreen broadleaved forest,desert steppe,the Loess Plateau and Minjiang estuary of China,such as the Institute of Geographic Sciences and Natural Resources Research,Fujian Normal University and Northwest Agriculture and Forestry University of Science and Technology. Meanwhile, the University of Arizona and University of Georgia have paid considerable attention to the stoichiometry in Chinese ecological regions. Meanwhile,with new research methods and techniques,the research on elements circulation and limit factors of the terrestrial and aquatic ecosystems gains a lot of attention and becomes a hotspot in research field under the continued support of the National Natural Science Foundation(NSFC). So far the domestic research area has extended to the Qinghai-Tibet Plateau alpine meadow,tropical and subtropical broad-leaved forest and other areas,still in the terrestrial ecosystem. But the international concern is more aquatic ecosystems such as " fresh water"," climate" " nutrient limitation" and other related research,Henceforth,eco-chemical metrology research will focus on climate change and nutrient dynamic balance model,nutrient elements(K,Na,Ca,S) on the ecological chemical measurement and gene effects and other aspects of research.
