International Comparison And Case Analysis On The Studies Of Invasive Alien Species In Forestry

With the increasingly rapid pace of international trade, tourism and economic globalization, invasive alien species has become the main barrier for the conservation of biodiversity and agriculture and forestry sustainable development, and it is commonly considered as one of the world's main environmental problems. Therefore, to effectivly prevent and control invasive alien species is one of the main tasks for forestry sustainable development.A bibliometric and competitive intelligence study on the available literature on invasive alien species in forestry indexed by Web of Science and CNKI during 1999-2008 was carried out. The basic structure of the collected literature was analyzed by text mining techniques. The level of the basic research, research application, and scientific and technological management of USA, Australia, England, Brazil, Souh Africa and Japan were compared. The current situation both globally and in China, as well as future trends of prevention and control of invasive alien species in forestry, was analyzed by keyword frequency analysis. Meanwhile, case study for two American and three Chinese typical invasive alien species was also carried out. An indicator system was set up for the benchmarking study. The research performance in the related field of the Institute of Botany, Chinese Academy of Sciences (CAS) was evaluated, in which five indicators were included, by comparing with Australia National University and the US Forest Service, the leading institutions in the field. The main results and innovation points are as follows.1. One hundred and sixteen countries published 3273 papers. Publications from USA and China ranked 1^st and 14^th, respectively. Of the 25 institutions which published most, 21 were from USA. CAS ranked among the top 25 institutions. The number of publications and the influence of these publications published by institutions in USA, Australia, Canada, New Zealand and England were greater than the rest, so these five countries were named top 5. Of 25 most cited papers, 22 were from USA, showing the great influence of American papers. Top one most cited paper was published by Washington State University. Forest Ecology and Management published mostly in the field. China published 4550 papers and Plant Quarantine published mostly based on CNKI.2. Keyword frequency analysis showed that China's main research direction was consistent with that of USA and the world, showing China's advantage and progress in the field of biodiversity, tropical forest etc. Some keywords, such as habitat disturbance, appeared with high frequency in the world, but were less represented in China, reflecting China's disadvantage and weakness in these particular fields.3. Science and technology input, international collaboration, legislation, subject distribution, research focus, research application, platform construction and fostering of talent were key success factors for the research, and prevention and control of invasive alien species in forestry.4. Case analysis indicated that quarantine step was effectively carried out in the US. Early control measures were timely and appropriate. So a good result was achieved.The order of top 20 countries was determined by the number of articles and their citations in the field of invasive alien species of forestry using normalized values from weighted indicators in bibliometrics. Hot topics were first identified by analyzing keywords of the articles published by the leading countries globally, and by USA and China, respectively as well as the case study. An international comparison on the related research was carried out using the theory and method of competitive intelligence. For the first time, the three typical competitive intelligence methods, advantage and disadvantage analysis, benchmarking and key-success-factor analysis were synthetically applied in the similar study.
