苏州中国花卉植物园温湿效应及其对人体舒适度的影响

探讨苏州城市景观公园不同群落温湿效应及其对人体舒适感的影响,为公园内部绿地系统的布局和植物种植规划提供参考。以苏州市中国花卉植物园园外道路和园内的道路、香樟林、栀子花林、槐树林、复合林6种不同样地为研究对象,测量分析各样地温湿度变化以及对人体舒适度的影响。结果表明：将园外沥青道路作为对照,在降温强度方面,园内不同样地的降温幅度0~4.2℃,依次为乔草>乔灌草>灌草>园内沥青道路;在增湿强度方面,园内不同样地的增湿幅度0~11.7%,香樟林、槐树林、复合林在白天的增湿效果十分明显。在不同季节,整个植物园相比于园外沥青道路有降温增湿的作用,人体舒适感增加,为人们户外活动提供了一个良好的选择。今后在公园的经营管理过程中,在植物配植方面,可以考虑以乔木为主体,选择单一或复合混交结构,合理建设游憩林等林下休闲场所,以最大限度改善生态环境,吸引更多游客。

China Flower Garden in Suzhou: Temperature and Humidity Effects and the Impact on Human Comfort Index

This paper discusses the temperature and humidity effect of different plant communities in urban landscape park of Suzhou and their impact on human comfort index, aiming to provide reference for the layout of the green space system and the planting planning. Six kinds of sample land including the external road and the internal road, camphor forest, gardenia garden, pagoda tree forest, complex forest of China Flower Garden in Suzhou were selected to study the change of temperature and humidity of different land and the effect on human comfort index. Results showed that, take the asphalt road outside the park as the control, in the aspect of cooling intensity, the temperature decrease of different sample land in the park was from 0 to 4.2℃, in an order of arbor-grass> arbor-bush-grass> bush-grass> the asphalt road inside the park; in the aspect of humidification intensity, humidity increase was from 0 to 11.7%, the humidification effect of camphor forest, pagoda tree forest, complex forest were obvious during the day. In different seasons, compared with the asphalt road outside the park, all kinds of sample land in the park had the effect of alleviating temperature and increasing humidity, which could improve human comfort index, making the park an excellent place for outdoor activities. In future plant selection and configuration, arbor can be considered as the main plant and the single or mixed structure can be selected for reasonably construct greening square under the trees to maximize the improvement of ecological environment and attract more tourists.
