城市用地语境下国内外城市绿地进化模拟研究进展

Research Progress on Urban Green Space Evolution Simulation at Home and Abroad in the Context of Urban Land Use

城市绿地进化耦合于城市用地变化,受人为活动与自然效应的综合影响,进化规律的总结归纳有助于探索城市绿地未来发展的可能性,然而目前缺乏对城市绿地进化模拟领域的系统性研究。基于中国知网(CNKI)文献数据库和Web of Science核心合集数据库,借助科学计量分析软件CiteSpace的知识图谱绘制功能,对2000-2020年城市绿地进化模拟的研究热点、研究主题分布和研究趋势等进行对比分析。结果表明:中英文文献研究的共性体现在对生态环境问题的重视以及研究尺度的聚焦。中英文文献研究的差异性体现在,中文文献聚焦空间特征挖掘的方法论总结,元胞自动机及其改进模型等技术路径的探讨,城市绿地降温效应及优化策略的探索,驱动机制分析;英文文献聚焦城市绿地进化与城市增长、土地利用变化之间的关系,城市绿地效能的延展,宏观尺度气候应对以及居民福祉研究,为城市用地的高效配置、城市绿地系统的科学规划提供理论支撑。未来可从结合学科学术研究热点、明晰用地或空间层面规划衔接等方面进行深入探讨。

The evolution of urban green space is coupled with changes in urban land use,and is affected by the combined effects of human activities and natural effects.Summarizing the evolution law is helpful to explore the possibility of future development of urban green space,but there is a lack of systematic research in the field of urban green space evolution simulation.Based on the literature database of CNKI and the core collection database of Web of Science,the research hotspots,research topic distribution and research trend of urban green space evolution simulation from 2000 to 2020 were analyzed with the scientific econometric analysis software CiteSpace.The research shows that the commonality of Chinese and English literature research is the attention to ecological and environmental issues and the focus on research scale.The differences between Chinese and English literature research are as follows:the Chinese literature focuses on the methodological summary of spatial feature mining,the discussion of technical paths such as cellular automata and its improved model,the exploration of cooling effect and optimization strategy of urban green space,and the analysis of driving mechanism.The English literature focuses on the relationship between urban green space evolution,urban growth and land use change,the extension of urban green space efficiency,the climate response in macro scale and the residents'well-being.This research provides theoretical support for the efficient allocation of urban land use and scientific planning of urban green space system.Future research can explore the academic research hotspots,the clarification of planning convergence of land use or space,etc.
