Research Progress and Hotspot Analysis of Low-Carbon Landscapes Based on CiteSpace Analysis

Abstract

Global climate change caused by carbon dioxide emissions has become a hot topic globally. It is of great significance to study how low-carbon landscapes can reduce carbon emissions and improve the ecological environment. In this study, CiteSpace software was used to conduct a bibliometric analysis of the research field. The analysis data were based on 2910 studies published in the research field from 2002 to 2023. By analyzing the number of publications in the research field, cooperation networks, keywords, etc., the research status, processes, and hotspots of low-carbon landscapes were systematically reviewed. The results show the following: (1) Between 2002 and 2023, low-carbon landscape research developed rapidly, gradually becoming a multidisciplinary field. A large number of studies were conducted by relevant institutions and scholars from 106 countries. (2) The research focuses on carbon emission reduction, renewable energy, life cycle assessment, etc. The research mainly goes through the following stages: theoretical research on low-carbon technology, the application of low-carbon technology, and the development of the low-carbon economy. (3) Research frontiers focus on low-carbon landscape emission-reduction technologies, low-carbon landscape research methods, and the development and application of low-carbon materials. This study deeply analyzes the research process of low-carbon landscapes and puts forward a research direction for low-carbon landscapes in future urban development, such as economic benefit assessments, ecosystem restoration and protection, social participation, and policy support, in order to provide a reference for low-carbon landscape research.
