Abstract:

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.

Key words: heat island effect, plant community, temperature, relative humidity
