Abstract

This article took Fuzhou City,the head of the latest four "furnace cities" as the research site. From the perspective of thermal environment,it took pocket parks as the research object,analyzed the relationship between pocket parks and the urban thermal environment through thermal environment measurement data,and discussed the relationship between the landscape characteristics of pocket parks and urban design indicators and urban thermal environment so as to provide suggestions for the construction and optimization of future pocket parks. The results showed that: 1) Pocket parks were cooler than surrounding city streets during the day and night,and can improve the urban thermal environment on a micro-scale. 2) Green coverage,area,shape index of pocket parks and thermal environment were negatively correlated,when the perimeter of the park was less than 300m,the relationship with the average temperature was positive,when the pocket park was greater than 300m,the relationship with the temperature was negative. 3) The building density had a significant positive relationship with the air temperature of the pocket park. At night,the display was relatively weak,the plot ratio had a parabolic relationship with the temperature,and the plot ratio exceeded a certain value (1.25) to reduce the ambient temperature. 4) The green coverage rate and shape index of the pocket park had a certain impact on the cooling degree of the surrounding environment. The greater the coverage,the more complex the shape index and the greater the temperature drops.

Key words： heat island effect; thermal environment; pocket park; landscape characteristics
