摘　　要：城市绿地植物是改善和提升城市环境质量的基本功能单位,负氧离子是反映城市绿地功能进而评价城市空气质量的基本参数之一。以北京奥林匹克森林公园绿地为研究对象,采用空间自相关及其他分析法探讨城市绿地负氧离子效益的空间特征。结果表明:负氧离子的空间关联性在局地内表现显著,但在整个绿地内不显著;负氧离子标准值与植被覆盖郁闭度和叶面积指数相关性均呈现正相关关系。研究为合理的城市绿地营建提供科学依据。The plants of urban green space are the basic functional unit of the green and fully plays the function of improving and promoting urban environmental quality, and Negative aeroion（NA） is one of the basic parameters of reflecting the function of green and evaluating air quality. The project studied the spatial pattern characteristics of the Plant community in Beijing Olympic Forest Park and Negative Aeroion Benefit（NAB） of it by GIS-spatial pattern autocorrelation analysis. Research shows that the spatial correlation between NAB and plants is significant in local area and not throughout in the green; and positive correlation between the standard values of NA and the canopy density, leaf area index. Based on the above results, it offers scientific basis for the planning of urban green spaces and building healthy urban living environment.
