摘要
在城市化给全球生物多样性带来巨大威胁的背景下,城市绿地生物多样性及其影响因素已成为生物多样性保护领域的研究热点之一。文章通过Web of Science和中国知网检索近20年来有关城市绿地生物多样性的相关文献,运用VOSviewer和Histcite软件进行分析,最终选取来自全球45个国家、127个城市的261篇文献,针对这些文献重点论述了绿地规模、植物群落结构、景观连接度、绿地周边环境、绿地管理与规划等7个影响城市绿地生物多样性的主要因素。在此基础上,针对目前城市绿地生物多样性研究存在的问题提出相关研究展望:1)在研究中注意选择具有联系的多个生物类群;2)扩展研究范围,研究对象选择上注重多尺度、多类型;3)开展不同时空特征下多因子间的耦合交互作用对城市绿地生物多样性的响应机制研究;4)构建系统性的城市绿地生物多样性监测网络和数据管理平台;5)加强国内外城市绿地生物多样性管理和保护经验的交流与借鉴。
Against the background that urbanization poses a great threat to global biodiversity,the biodiversity in urban green spaces(BUGS) and its influencing factors have become one of the research hotspots in the field of biodiversity conservation.This paper retrieves relevant literature on the BUGS over the past two decades from the Web of Science and CNKI,employs VOSviewer and Histcite software for analysis,and ultimately selects 261 papers from 127 cities in 45 countries worldwide.Based on these selected papers,7 factors influencing the BUGS are discussed,including size of green space,plant community structure,landscape connectivity,the surrounding environment of green spaces,and green space management and planning.Based on the analyses,the paper comes up with future research directions against the problems existing in the research on the BUGS,including:1) The selection of multiple biotic groups with ecological connections;2) Expansion of the research scope,with the emphasis on multiscale and multitype selections of research objects;3) The response mechanisms of the BUGS to coupled interactions among multiple factors under different spatio-temporal characteristics;4) Systematic BUGS monitoring network and data management platform;and 5) The exchange and learning of international and national experiences in BUGS management and conservation.
