摘　　要：城市绿地对于提高城市人居环境质量、维护居民公共健康具有重要作用。空气负离子是评价城市空气清洁度的基本参数之一。以北京奥林匹克森林公园绿地为例,选定典型植物群落结构、群落类型及典型景观环境样点,基于多年连续动态持续测定并选取典型年度数据(2020年),分析和阐释该公园绿地区域空气负离子空间的分异特征。结果表明,在公园绿地中不同植物群落结构区域的空气负离子浓度:复层>双层>单层、乔草>乔灌>灌草;不同植物群落类型区域的空气负离子浓度:落叶阔叶型>常绿针叶型>草本地被型>针阔叶混交型>灌丛;不同典型景观环境中的空气负离子浓度:滨水植物群落>复层/单层植物群落>滨水广场;公园绿地空气负离子浓度与郁闭度、叶面积指数呈现显著的相关关系。研究结果为基于循证设计的功能型城市绿地规划设计及更新优化提供基础科学依据。Urban green space plays an important role in improving the quality of urban living environment and maintaining the public health of residents.Negative air ion(NAI)is one of the basic parameters to evaluate urban air cleanliness.Taking the urban green space of Beijing Olympic Forest Park(BOFP)as an example,this research selects the typical plant community structure,type and landscape environment test sample points,and analyzes and explains the spatial differentiation characteristics of NAI in BOFP based on the continuous dynamic measurement data for 15 years.The results showed that the concentration of NAI in different plant community structure areas of BOFP was MPC>DPC>SPC;TG>TS>SG;the concentration of NAI in different plant communities was DBP>CP>G>CBP>S;that in different landscape environments was as follows:WPC>MPC/SPC>WS;and there was a significant correlation between NAI,CD,and LAI.This research results provide the basically scientific basis for the planning,design,renewal and optimization of functional urban green space based on"evidencebased design".
