摘　　要：【目的】明晰园林植物气味类型和浓度对人身心健康的影响,探究气味刺激下生理反应与主观感受之间的契合度,为后续园林植物气味的人体健康效应研究指标选择提供参考,为科学健康的嗅景营造提供理论依据。【方法】以秋季嗅景中常见的桂花花朵、银杏外种皮为气味材料,分别代表积极、消极2种气味类型,通过预试验设定低、高2种气味浓度水平,采用COSMOS XP-329ⅢR便携式气味传感器制备低浓度和高浓度桂花、低浓度和高浓度银杏4组气味材料。招募52名大学生参与试验,采用ErgoLAB、Emotiv Epocx测定其生理指标,以愉悦度量表、熟悉度量表、气味强度量表及气味情绪量表(ScentMove?问卷)收集其主观感知及情绪指标。通过方差分析、非参数检验比较气味类型和浓度对各身心指标的影响差异,再以斯皮尔曼等级相关分析法检验生理指标与心理指标之间的相关性。【结果】1)前测气味强度受气味浓度和类型的影响显著(P<0.05、P<0.01),后测气味强度仅受气味类型影响显著(P<0.05)。2)ScentMove?问卷的六大情绪指标(感性、放松、幸福、能量、怀旧、厌恶)受气味浓度影响均不显著(P>0.05),但受气味类型影响均显著(P<0.01);愉悦度与六大情绪中的感性、放松、幸福、能量和怀旧显著正相关(P<0.01),与厌恶显著负相关(P<0.01);气味熟悉度与幸福、放松、怀旧和能量显著正相关(P<0.01),与厌恶显著负相关(P<0.05);气味强度与六大情绪指标相关性不显著。3)皮肤电导水平(SCL)、平均心率(AVHR)、全部正常窦性心搏间期的标准差(SDNN)、全程相邻正常窦性心搏间期差值的均方根(RMSSD)受气味浓度影响不显著(P>0.05),受气味类型影响显著(P<0.01);α脑波受气味类型和浓度影响均不显著(P>0.05);θ脑波、低频β(βL)脑波、高频β(βH)脑波受气味浓度影响显著(P<0.05、P<0.01、P<0.05),受气味类型影响不显著(P>0.05【Objective】To clarify the influence of landscape plant odor types and odor concentrations on human physical and mental health,explore the correlation between physiological responses and subjective perceptions under odor stimulation,provide indicators selection reference for subsequent studies on the effects of landscape plant odor on human health and theoretical basis for smellscape design and optimization.【Method】This study utilized ginkgo sarcotesta and osmanthus flowers,common odorous materials in autumn,representing positive and negative odor types,respectively.Through pre-experiments,low and high odor concentration values were set,and COSMOS XP-329IIIR portable odor sensor was used to prepare four groups of odor materials:low-concentration osmanthus,high-concentration osmanthus,low-concentration ginkgo,and high-concentration ginkgo.Fifty-two university students were recruited for the experiment,and their physiological indicators were measured by ErgoLAB and Emotiv Epocx,while their subjective perceptions and emotional indicators were collected using pleasure rating scales,familiarity rating scales,odor intensity rating scales,and odor emotion scales(ScentMove®questionnaire).Compare the differences in the effects of odor types and concentrations on various physical and mental indicators through analysis of variance and non-parametric tests,and then use Spearman rank correlation analysis to test the correlation between physiological and psychological indicators.【Result】1)The pre-measured odor intensity was significantly affected by odor concentration and odor type(P<0.05,P<0.01),while the post-measured odor intensity was only significantly affected by odor type(P<0.05).2)The six emotional indicators of the ScentMove®questionnaire(desire,peacefulness,happiness,energy,nostalgia,unpleasant feelings)were not significantly affected by odor concentration(P>0.05),but were significantly affected by odor type(P<0.01).Pleasantness was significantly positively correlated with positive emotions such as desir
