中国城市森林建设范围与研究尺度

Development Scope and Research Scale of Urban Forest in China

建设城市森林是我国推进城市生态系统修复和改善人居环境的重要手段。我国城市生态建设正经历着观念和路径的巨大转变,即建设思路更加强调生态系统观、建设实践更加强调科学绿化观、建设目标更加强调人与自然和谐观;城市森林生态系统包括自然涵盖范围和人为管理范围2种空间范围,科学研究主要关注个体、地块(群落)、城近郊区、市域行政区和城市群5个尺度。在此基础上,文章分析了城市森林建设管理和科学研究中尺度不匹配带来的问题,并提出了应对策略。

Urban forest development is an important means to promote urban ecosystem restoration and improve living environment.It is held that urban ecological development is experiencing a great change in concept and path in China.The concept of ecosystem is more stressed development ideas,the concept of scientific greening is more favored development practice,and the concept of harmony between urban people and nature is more highlighted development goal.The development and management of urban forest ecosystem includes two spatial ranges:natural coverage and man-made management.Scientific research mainly focuses on five scales:individual,plot(community),urban outskirt,municipal administrative region and city cluster.On this basis,the problems caused by the mismatch between urban forest development and management and scientific research are analyzed,and the countermeasures are put forward.
