Exploring the Evolutionary Path,Current Status,and Development Frontier of Carbon Sequestration Research Based on Big Data of Literature
Amid the environmental crisis triggered by climate change,carbon dioxide emissions have emerged as a pivotal issue,impacting human life and socio-economic development.This study,leveraging the China National Knowledge Internet(CNKI),conducted a quantita-tive and thematic modeling analysis of 4 241 core journal articles in the carbon sequestration field from 2020 to 2023.Utilizing Excel and Citespace tools,it presented a multi-dimensional analysis of the quantity,temporal distribution,authors,and research institutions.Further-more,the LDA model was employed to explore the research themes and their evolution.The results indicated a substantial and high-quality output in carbon sequestration research,The core journals were highly concentrated,and there was robust collaboration among authors.The research themes had expanded over time,evolving from seven themes such as carbon sequestration and reserves in the early period,to nine themes including ecology and emissions in the mid-period,and finally to ten themes encompassing agriculture and development in the recent period.This reflected a deepening and refinement trend in carbon sequestration research.
