Based on environmental psychology and human physiology, the subjective questionnaires as well as physiological measurements were introduced to investigate the effects of the outdoor vegetations on human comfort and satisfaction level. Environment zone located in Shanghai Botanical Garden formed by different vegetations were chosen for the experiment, and those vegetations were different in color, scent and size. The 240 questionnaires were collected, the measurement of physiological parameters for 64 visitors were taken, questionnaire and test results of different zones were analyzed and compared to evaluate the effect of vegetation on human. The results show that compared with environment without vegetation, the satisfaction and comfort level of environment is significantly improved by the vegetation. Color as well as the scent of the vegetation contribute most to the overall satisfaction. The expectations of human beings for the vegetation are changed in different vegetation environments. For example, large area vegetation zone and flower grass zone are the most welcomed. The physiological parameters reflect human comfort in specific vegetation environment, and the correlations of human heart rate variability and environmental amenity is significant.%基于环境心理学和人体生理学,采用主观问卷调查并结合客观生理参数测量的方式,为营造人体造舒适满意的室外环境,对室外植物属性对人体舒适度及满意度的影响进行研究.在上海植物园内选取由不同颜色、大小、气味等植物构成的局部特征环境进行研究,并进行有无植物环境的对比实验,收集有效主观问卷240份,并对64位不同性别及年龄段的游客生理参数进行测试.通过比较不同植物环境下人体主观舒适度及客观生理参数的变化,研究植物的不同属性对人体舒适度及环境满意度的影响.研究结果表明:相对比无植物环境,人体在植物环境下的总体满意率和舒适度得到显著提高,而植物的颜色和气味的作用最为显著;不同植物环境下受试者的期望不同,大面积、多色彩的植物环境花草园环境的受欢迎程度最高,生理参数能从一定程度上反映人体在环境中的舒适状态,其中心率变异性与环境舒适度的相关性最为明显.
