植物特性与室内环境满意度的关系初步研究

Relationship between dominant feature of indoor plants and indoor environment satisfaction

目的探讨植物特性与室内环境满意度的关系。方法选取了6种常见的室内植物(薄荷、薰衣草、海芋、虎尾兰、一品红、碰碰香),并选取了16名在校大学生作为受试者,采用调查问卷的方式,研究植物颜色、气味、叶形尺寸、数量对受试者的舒适度和满意度的影响,并测定受试者的血氧饱和度和呼吸频率。结果相比于无植物的室内环境,超过75%的受试者认为摆放有上述植物的环境更加愉悦。与室内环境满意度相关的植物特性为气味(r=0.653,P<0.01)、颜色(r=0.437,P<0.05)、叶形尺寸(r=0.377,P<0.01)、数量(r=0.349,P<0.05)。其中,清淡气味的满意度投票均值大于无味和浓烈气味。未发现植物对休息状态下的受试者的血氧饱和度和呼吸频率有显著影响。结论本次研究的室内植物可以明显增加人员的愉悦感,提高环境满意度。

Objective To explore the relationship between the dominant feature of indoor plants and indoor environment satisfaction （IES）. Methods The effects of plants＇ color, scent, size and amount on IES were discussed, six different common indoor plants were selected, including Mentha haplocalyx, Lavandula angustifolia mill, Alocasia macrorrhiza, Sansevieria trifasciata, Euphorbia pulcherrima willd and Plectranthus tomentosa. A total of 16 college students were recruited as the subjects for the experiment. The human comfort and environment satisfaction were investigated with subjective questionnaires and the subjects＇ physiological parameters, including SPO2 and respiration rate, were measured to observe the human instant response to the indoor environment. Results Over 75% of the participants preferred the indoor environment with plants than that without plants. As for the effects on IES, the sequence decreasingly was the scent of plants （r=0.653, P〈0.653）, color （r=0.437, P〈0.437）, the size of the leaf （r=0.377, P〈0.01） and the amount （r=0.349, P〈0.05） according to the Pearson＇s correlation coefficient. In addition, the satisfactory degree of light scent was higher than that of none and strong scent. No effects of indoor plants on subjects＇ SPO2 and respiratory rate were observed. Conclusion Compared with the condition without indoor plants, indoor plants can significantly increase the joyful voting and satisfaction ratio.
