城市公园绿地对城市热环境降温效应研究
Study on the Cooling Effect of Urban Park Green Space on Urban Thermal Environment:A Case of the Main Urban are of Hefei City
摘要
Abstract
Urban park green space is an important way to improve the urban heat island effect.This paper inverts the surface temperature of the main urban area of Hefei through remote sensing images,quantifies the area and perimeter shape characteristics of the landscape patches of park green space,and explores their impact on the cooling range and magnitude of park green space.The results show that the fitting curve between the buffer distance and the average temperature of the buffer zone is a cubic function.As the distance increases,the temperature of the buffer zone shows a trend of first increasing significantly and then falling back.The average temperature of the selected park green space samples(35.27℃)was lower than the average temperature of the study area(35.39℃).The average cooling range of the sample is 3.02℃.The cooling range of different park green spaces varies,with the maximum cooling range being 480 m and the minimum being 66 m.The four indicators of green space area,perimeter,water area and perimeter are all positively correlated with cooling distance and cooling amplitude.关键词
