Analysis And Research On Biodiversity Of Urban Green Space Based On Bibliometrics

Biodiversity is the material basis of human survival,and plays an important role in human survival,development and civilization.The biodiversity of urban green space is an important and special component of biodiversity,which plays an important role in the global biodiversity.With the rapid development of urban construction,the biodiversity of urban green space is decreasing,which leads to the imbalance of urban ecosystem and the sustainable development of cities.Therefore,urban green space biodiversity has gradually become the focus of attention of governments and researchers.A systematic study of urban green space biodiversity will provide a strong guarantee for the sustainable development of the city and the health of human beings.Based on the relevant theoretical knowledge of bibliometrics,this paper uses CNKI and Web of science core collection database to screen the domestic and international research literature on biodiversity of urban green space from 1997 to 2017,and adopting the literature data method,logical analysis method,mathematical statistics method,scientific knowledge map analysis method,and the Excel and Cite Space visual analysis tools.The basic structure of the journal papers is analyzed,and the hot spots and trends of the domestic and international research fields are further analyzed through the study of key word frequency and centrality.From 1997 to 2017,there were 345 papers published in this field in China.Although the annual quantity of the papers was fluctuating,they were on the rise as a whole;Liu Ping,Hou Biqing,Lu Min,GE Baoming and Hao Riming were the leading figures in this field and had strong academic influence;The distribution of journal papers in this research field is in accordance with Bradford's law,and has basically reached a mature stage."Chinese Gardens","Anhui Agricultural Science","Journal of Northwest Forestry University" is the most published core journal.There are 284 journal papers cited in this field,accounting for 82.3%of the total amount of documents,among which the "city green corridor research" has been cited the highest number of times,reaching 553 times.,and 284 journal papers in this field have been cited.Based on the word frequency analysis of key words,it is concluded that some hot issues,such as landscape pattern,urban green space system,species diversity,landscape ecology and so on,have been paid more attention in China.Bird community,biodiversity conservation strategies and urban biodiversity evaluation system in urban green space are the hot issues emerging in this field and a new research direction in the future.From 1997 to 2017,there were 322 international journal papers in this field.There are 59 papers published in the United States,44 in Britain,42 in China,and less than 30 in other countries.It can be seen that the United States has a strong level of research in this field.Through the analysis of the author's information,GASTON KJ,WARREN PH and JIM CY are the authors of the top three papers.According to the analysis of journals,the core journals of the top three are LANDSCAPE AND URBAN PLANNING,URBAN ECOSYSTEMS,and URBAN FORESTRY.URBAN GREENING,a total of 113 papers,accounted for 35%of the total volume of documents,of which "LANDSCAPE AND URBAN PLANNING" was cited as the total frequency,the number of cited citations,and the publication capacity were the highest.It is the influential journals;322 papers involved 42 kinds of research directions,and papers studies were highly cross-cut.By drawing key words co-occurrence maps and frequency tables,we learned that international research hotspots in this area include diversity,diversity,conservation,urbanization,and green space.According to the research trend time zone map,the main mutations in recent years are ecosystem service,resilience,biocultural diversity,and domestic garden.Scholars have begun to pay more attention to integrating planning and ecological concepts into research in this field.Intensified,in-depth and integrated,these research hotspots will become the research trends of the international urban green space biodiversity in the future.
