Panoramic knowledge graph of transformation and development of resource-based cities in China:Evolution,hotspots tracking and future prospects
Resource-based cities(RBCs)are a unique type of cities in China that have significantly contrib-uted to China's national economy.However,the development of RBCs has encountered challenges,and their transformation and development require urgent attention due to the depletion of resources in RBCs and the need to comply with national ecological environment protection requirements in the 21st century.To explore the hotspots and frontiers of RBCs'transformation and development,this paper analyzes 602 CSSCI journal papers published between 1999 and 2021.The research distribution was analyzed from 3 aspects:time,journal and author distribution,using software such as CiteSpace,VOSviewer,Data source,scientific knowledge graph.The paper explores the overall situation from evolution,hotspots and frontier.The conclusions are as follows:1)The transformation and development of RBCs has gradually entered the Chinese government's and academia's vision since the 1980s,but substantive research only began in 2004.2)From a time distribution perspect-ive,research on the transformation and development of RBCs in China can be roughly divided into 3 periods:slow exploration period(1980s-2003),high-speed growth period(2004-2013)and steady progress period(2014-);In terms of journal distribution,China Population,Resources and Environment,Economic Geography,Journal of Natural Resources,Geographical Research and Scientia Geographica Sinica are notable journals that signific-antly supported and led studies on RBCs.Regarding authorship,the study found that Yu Jianhui,Qiu Fangdao,Zhang Wenzhong and Jiao Huafu have had great influence and contribution in this field.3)The study also identified 6 research frontier trends:green transformation and development of RBCs,population shrinkage of RBCs,carbon emissions of RBCs,spatial reconstruction of RBCs,innovation and transformation development of RBCs,comprehensive management of two special difficult areas of coal mining subsidence areas and inde-pendent industrial and mining areas.Finally,the study proposed future research directions in four aspects:high-quality development of RBCs,smart development of RBCs,carbon emission reduction of RBCs and spatial de-velopment of RBCs.
