Research hotspots and trends in wetland restoration technology based on CiteSpace Software
With the influence of climate change and anthropogenic activities,wetlands have experienced severe area reduction and ecological degradation.Research on wetland restoration technology has attracted widespread attention;however,the understanding of the development trends and evolutionary characteristics of research hotspots remains scarce.Using 1 013 literatures retrieved from the WOS and CNKI databases as data sources,CiteSpace was used to visually analyze the number of publications,authors,and keyword document co-citations.International research on wetland restoration technology began in 1994 and has shown a rapidly increasing trend since 2011.Domestic research in China has been improving since 2005 and had global impacts.Internationally,core teams such as Mitsch WJ-Stefanik KC,Day JW-Shaffer GP,and Tong SZ-Wang XH have published more papers,which will have a prominent impact on this research direction in the future.China has formed core teams,such as LU Xianguo,TONG Shouzheng,WANG Xuehong,CUi Lijuan,LI Wei,ZHANG Manyin,ZHAO Xinsheng,WANG Yifei,DUAN Liang,and SONG Yonghui.In addition,Shandong,Heilongjiang,Jiangsu,and other locations remain core research areas and research on high-cold and high-latitude areas may be strengthened.In general,national and international research on wetland restoration technology is rapidly developing.International research has focused on hydrological and water environment restoration,vegetation restoration and succession,regulation and control of environmental pollution by constructed wetlands,and biodiversity restoration,giving importance to nutrient cycling and constructed wetland restoration,soil seed bank,vegetation restoration,and degradation technologies.Coastal wetland ecosystem construction and integration technologies,ecological engineering operations,and their effects may become novel research hotspots.Domestic research themes are consistent with international research and a unique technical system has been formed.In the future,the restoration technology of constructed wetlands,comprehensive treatment technology of bays,purification technology of wastewater,and certain collaborative joint restoration technology may be research hotspots.Networking research must be conducted on wetland restoration technology at the national scale and a technical standard and theoretical system of wetland restoration suitable for the regional characteristics of China must be constructed crucially to conduct long-term and timely ecological monitoring and evaluation of wetland restoration and protection.
