国际景观生态学研究新进展   总被引:26,自引:13,他引:26  
20世纪90年代中期以来,国际景观生态学发展迅速.景观生态学研究最为活跃的地区集中在北美、欧洲、大洋洲(澳大利亚)、东亚(中国),表明景观生态学理论、方法和应用的广泛性和越来越高的认知度.从研究内容上看,景观生态评价、规划和模拟一直占居主导地位,其次是景观生态保护与生态恢复、景观生态学的理论探讨.随着景观生态学研究的深入,以科学和实践问题为导向的学科交叉与融合不断加强,促进了景观生态学新的学科生长点的形成和发展,主要包括水域景观生态学、景观遗传学、多功能景观研究、景观综合模拟、景观生态与可持续性科学.在全球化背景下,中国的景观生态学研究也已经取得了长足进展,国际同行开始关注并在重要学术刊物上评介中国的景观生态学研究,标志着中国景观生态学已逐步走上国际舞台.然而,中国景观生态学进一步发展的挑战和机遇并存.中国科学家需要抓住人类对可持续发展和可持续性科学的共同夙求,放眼国际前沿、服务本土需求,从中国自身的特色出发,关注受人类干扰的和以人为主导的景观,以景观格局与生态过程的多尺度、多维度耦合研究为核心,区域综合与区内分异并重,推动综合整体性景观生态学的建立和完善.  相似文献

基于Web of Science的国际海草研究文献计量评价   总被引:2,自引:0,他引:2  
海草及其与周围环境形成的海草场是近海海洋生态系统的重要组成部分,具有多种重要的生态服务功能。相较于红树林和珊瑚礁,国内外学者和公众对海草的关注度偏低,至今对国际海草研究的现状、趋势和热点等的认识还较为有限。检索了1983-2017年Web of Science的SCI-E数据库中收录的海草研究相关文献,借助文献计量信息可视化分析方法,从年度发文量、研究力量和研究热点与主题等方面进行了较为系统的文献计量评价,以期阐明国内外海草研究的态势与热点。结果表明:1983-2017年间国际海草研究的文献数量总体呈明显上升趋势,该领域发文量排前3位的国家是美国、澳大利亚和西班牙;全球发文量最多的机构是佛罗里达州立大学,其次是西班牙高等科学研究理事会与美国国家海洋和大气管理局;发文总量较多的作者是Duarte CM、Marba N和Fourqurean JW,近3年发文量最高的是学者Santos R;刊文量最多的期刊分别是《Marine Ecology Progress Series》、《Aquatic Botany》和《Estuarine, Coastal and Shelf Science》,刊文量前15期刊中影响因子最高的是《Limnology and Oceanography》(3.969)。在国家、机构与作者合作方面,西班牙、丹麦、荷兰、墨西哥4个国家形成了关系密切的合作网络,西班牙高等科学研究理事会和美国国家海洋和大气管理局是海草研究机构合作网络中的两个中心,Duarte CM、Marba N等较多学者间有紧密的学术合作关系。通过高频关键词的关联关系分析,表明该领域的3个热点研究主题,即环境(污染)胁迫对海草场的影响、海草的生长与生理生态和海草及其相关生态系统的结构与功能。中国科学院、中国海洋大学等机构为我国海草研究做出了重要贡献,但由于研究起步较晚,我国学者的发文量、篇均被引频次等与欧美国家学者存在一定差距,但近几年的发文量增长迅速,预计未来的发展趋势良好。  相似文献

Background

The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI). Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor.

Methodology/Principal Findings

We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as ‘world’) journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates.

Conclusions/Significance

Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented.  相似文献

Emerging countries have established national scientific journals as an alternative publication route for their researchers. However, these journals eventually need to catch up to international standards.Since the first scientific journal was founded—The Philosophical Transactions of the Royal Society in 1665—the number of journals dedicated to publishing academic research has literally exploded. The Thomson Reuters Web of Knowledge database alone—which represents far less than the total number of academic journals—includes more than 11,000 journals from non-profit, society and commercial publishers, published in numerous languages and with content ranging from the natural sciences to the social sciences and humanities. Notwithstanding the sheer scale and diversity of academic publishing, however, there is a difference between the publishing enterprise in developed countries and emerging countries in terms of the commercial rationale behind the journals.…‘national'' or even ‘local'' journals are published and supported because they report important, practical information that would be declined by international journals…Although all academic journals seek to serve their readership by publishing the highest quality and most interesting advances, a growing trend in the twentieth century has also seen publishers in developed countries viewing academic publishing as a way of generating profit, and the desire of journal editors to publish the best and most interesting science thereby serves the commercial interest of publishers who want people to buy the publication.In emerging countries, however, there are few commercial reasons to publish a journal. Instead, ‘national'' or even ‘local'' journals are published and supported because they report important, practical information that would be declined by international journals, either because the topic is of only local or marginal interest, or because the research does not meet the high standards for publication at an international level. Consequently, most ‘national'' journals are not able to finance themselves and depend on public funding. In Brazil, for instance, the national journals account for one-third of the publications of all scientific articles from Brazil and are mostly funded by the government. Other emerging countries that invest in research—notably China, India and Russia—also have a sizable number of national journals, most of which are published in their native language.There is little competition between developed countries to publish the most or the best scientific journals. There is clear competition between the top-flight journals—Nature and Science, for example—but this competition is academically and/or commercially, rather than nationally, based. In fact, countries with similar scientific calibres in terms of the research they generate, differ greatly in terms of the number of journals published within their borders. According to the Thomson Reuters database, for example, the Netherlands, Switzerland and Sweden published 847, 202 and 30 scientific journal, respectively, in 2010—the Netherlands has been a traditional haven for publishers. However, the number of articles published by researchers in these countries in journals indexed by Thomson Reuters—a rough measurement of scientific productivity—does not differ significantly.To overcome the perceived dominance of international journals […] some emerging countries have increased the number of national journalsScientists who edit directly or serve on the editorial boards of high-quality, international journals have a major responsibility because they guide the direction and set the standards of scientific research. In deciding what to publish, they define the quality of research, promote emerging research areas and set the criteria by which research is judged to be new and exciting; they are the gatekeepers of science. The distribution of these scientists also reflects the division between developed and emerging countries in scientific publishing. Using the Netherlands, Switzerland and Sweden as examples, they respectively contributed 235, 256 and 160 scientists to the editorial teams or boards of 220 high-impact, selected journals in 2005 (Braun & Diospatonyi, 2005). These numbers are comparable with the scientific production of these countries in terms of publications. On the other hand, Brazil, South Korea and Russia, countries as scientifically productive in terms of total number of articles as the Netherlands, Switzerland and Sweden, contributed only 28, 29 and 55 ‘gatekeepers'', respectively. A principal reason for this difference is, of course, the more variable quality of the science produced in emerging countries, but it is nevertheless clear that their scientists are under-represented on the teams that define the course and standards of scientific research.To overcome the perceived dominance of international journals, and to address the significant barriers to getting published that their scientists face, some emerging countries have increased the number of national journals (Sumathipala et al, 2004). Such barriers have been well documented and include poor written English and the generally lower or more variable quality of the science produced in emerging countries. However, although English, which is the lingua franca of modern science (Meneghini & Packer, 2007), is not as great a barrier as some would claim, there is some evidence of a conscious or subconscious bias among reviewers and editors in judging articles from emerging countries. (Meneghini et al, 2008; Sumathipala et al, 2004).A third pressure has also forced some emerging countries to introduce more national journals in which to publish academic research from within their borders: greater scientific output. During the past two or three decades, several of these countries have made huge investments into research—notably China, India and Brazil, among others—which has enormously increased their scientific productivity. Initially, the new national journals aspired to adopt the rigid rules of peer review and the quality standards of international journals, but this approach did not produce satisfactory results in terms of the quality of papers published. On the one hand, it is hard for national journals to secure the expertise of scientists competent to review their submissions; on the other, the reviewers who do agree tend to be more lenient, ostensibly believing that peer review as rigorous as that of international journals would run counter to the purpose of making scientific results publicly available, at least on the national level.The establishment of national journals has, in effect, created two parallel communication streams for scientists in emerging countries: publication in international journals—the selective route—and publication in national journals—the regional route. On the basis of their perceived chances to be accepted by an international journal, authors can choose the route that gives them the best opportunity to make their results public. Economic conditions are also important as the resources to produce national journals come from government, so national journals can face budget cuts in times of austerity. In the worst case, this can lead to the demise of national journals to the disadvantage of authors who have built their careers by publishing in them.…to not publish, for any reason, is to break the process of science and potentially inhibit progressThere is some anecdotal evidence that authors who often or almost exclusively publish in international journals hold national journals in some contempt—they regard them as a way of avoiding the effort and hassle of publishing internationally. Moreover, although the way in which governments regard and support the divergent routes varies between countries, in general, scientists who endure and succeed through the selective route often receive more prestige and have more influence in shaping national science policies. Conversely, authors who choose the regional publication route regard their efforts as an important contribution to the dissemination of information generated by the national scientific community, which might otherwise remain locked away—by either language or access policies. Either way, it is worth mentioning that publication is obviously not the end point of a scientific discovery: the results should feed into the pool of knowledge and might inspire other researchers to pursue new avenues or devise new experiments. Hence, to not publish, for any reason, is to break the process of science and potentially inhibit progress.The choice of pursuing publication in regional or international journals also has direct consequences for the research being published. The selective, international route ensures greater visibility, especially if the paper is published in a high-impact journal. The regional route also makes the results and experiments public, but it fails to attract international visibility, in particular if the research is not published in English.It seems that, for the foreseeable future, this scenario will not change. If it is to change, however, then the revolution must be driven by the national journals. In fact, a change that raises the quality and value of national journals would be prudent because it would give scientists from emerging countries the opportunity to sit on the editorial boards of, or referee for, the resulting high-quality national journals. In this way, the importance of national journals would be enhanced and scientists from emerging countries would invest effort and gain experience in serving as editors or referees.The regional route has various weaknesses, however, the most important of which is the peer-review process. Peer-review at national journals is simply of a lower standard owing to several factors that include a lack of training in objective research assessment, greater leniency and tolerance of poor-quality science, and an unwillingness by top researchers to participate because they prefer to give their time to the selective journals. This creates an awkward situation: on the one hand, the inability to properly assess submissions, and on the other hand, a lack of motivation to do so.Notwithstanding these difficulties, most editors and authors of national journals hope that their publications will ultimately be recognized as visible, reliable sources of information, and not only as instruments to communicate national research to the public. In other words, their aspiration is not only to publish good science—albeit of lesser interest to international journals—but also to attain the second or third quartiles of impact factors in their areas. These journals should eventually be good enough to compete with the international ones, mitigating their national character and attracting authors from other countries.The key is to raise the assessment procedures at national journals to international standards, and to professionalize their operations. Both goals are interdependent. The vast majority of national journals are published by societies and research organizations and their editorial structures are often limited to local researchers. As a result, they are shoestring operations that lack proper administrative support and international input, and can come across as amateurish. The SciELO (Scientific Electronic Library Online), which indexes national journals and measures their quality, can require certain changes when it indexes a journal, including the requirement to internationalize the editorial body or board.…experienced international editors should be brought in to strengthen national journals, raise their quality and educate local editors…In terms of improving this status quo, a range of other changes could be introduced. First, more decision-making authority should be given to publishers to decide how to structure the editorial body. The choice of ad hoc assistants—that is, professional scientists who can lend expertise at the editorial level should be selected by the editors—who should also assess journal performance. Moreover, publishers should try to attract international scientists with editorial experience to join a core group of two or three chief or senior editors. Their English skills, their experience in their research field and their influence in the community would catalyse a rapid improvement of the journals and their quality. In other words, experienced international editors should be brought in to strengthen national journals, raise their quality and educate local editors with the long-term objective to join the international scientific editing community. It would eventually merge the national and the selective routes of publishing into a single international route of scientific communication.Of course, there is a long way to go. The problem is that many societies and organizations do not have sufficient resources—money or experience—to attract international scientists as editors. However, new publishing and financial models could provide incentives to attract this kind of expertise. Ultimately, relying on government money alone is neither a reliable nor sufficient source of income to make national journals successful. One way of enhancing revenue streams might be to switch to an open-access model that would charge author fees that could be reinvested to improve the journals. In Brazil, for instance, almost all journals have adopted the open access model (Hedlund et al, 2004). The author fees—around US$1,250—if adopted, would provide financial support for increasing the quality and performance of the journals. Moreover, increased competition between journals at a national level should create a more dynamic and competitive situation among journals, raising the general quality of the science they publish. This would also feed back to the scientific community and help to raise the general standards of science in emerging countries.  相似文献
