摘要
基于Web of Science平台相关文献数据,利用CiteSpace与空间分析方法探讨低碳乡村的研究区域时空分布格局,识别低碳乡村研究演进和热点趋势,结论如下:①全球范围内乡村碳排放研究时间连续、跨度大,发达国家起步先于发展中国家,并形成以中美为两极的地理分异特征;②乡村碳排放围绕环境生态科学与农学等多学科交叉,呈现主题拓展与量化模型精度提升并进趋势;③乡村碳排放的五大研究主题为耕作方式、生物燃料与土地利用变化、农业—食物—环境系统、可持续饮食和乡村温室气体的测算与产业管理;④中国存在重乡村旅游、轻饮食结构及温室气体测算中内涵界定范围局限且精细度低等问题。基于上述结论,结合我国“一带一路”、乡村转型和乡村振兴等政策,从乡村碳排放跨区域协调、碳税与环境税的试点实践、乡村产业智能化管理体系构建、国民饮食结构调整等方面对未来研究进行展望,以期为我国低碳乡村发展提供参考。
Based on relevant literature in the Web of Science Core Collection,this paper uses CiteSpace and spatial analysis methods to explore the spatial and temporal distribution pattern of the research areas of low-carbon rural and identify the evolution and trends of low-carbon rural research.The conclusions are as follows:①The study of carbon emissions in rural areas began with a focus on developed countries,and later expanded to include developing countries.This research spanned across time and space,with China and the United States emerging as key geographical differentiators.②The research on rural carbon emissions involves many disciplines such as environmental ecological science and agronomy,and reveals a concurrent trend of expansion of research topics and improved quantitative management model correctness.③The five major topics of rural carbon emissions research are farming practices,biofuels and land use changes,agricultural-food-environment systems,sustainable diets,and rural greenhouse gas measurement and industrial management.④Research in China has some limitations,such as a focus on rural travel rather than dietary structure,limited scope and low degree of refinement of greenhouse gas measurement.Based on the above conclusions,combined with China′s"the Belt and Road Initiative",rural transformation and rural revitalization policies,the future research is prospected from the aspects of cross-regional coordination of rural carbon emissions,pilot practice of carbon tax and environmental tax,construction of intelligent management system of rural industries,and adjustment of national diet structure,so as to provide reference for the development of low-carbon rural areas in China.
