Empirical Analysis of the Effect of Plant Configuration on Microclimate of Rooftop Space—A Case Study of Kunming Main Urban Area
Green roofs can have a positive impact on the microclimate of outdoor spaces and stimulate residents'motivation and participation in outdoor activities.This paper selects a green roof in each of the four directions in the main urban area of Kunming,analyses the impact of plant configuration forms on the microclimate of the roof space and its changing law,and carries out field monitoring of the microclimate environment from 8:00 to 20:00 on 1 March 2024 to compare and analyze the changing law of the microclimate.The results show that:single ground cover has little influence on the microclimate of the roof,and the composite configuration of trees,shrubs and grasses has great influence on the microclimate environment;the planting form with high plant abundance,large number of plants and high density,and the formation of a certain enclosure space has a certain influence on the microclimate;the space with high coverage and shade has an influence on the temperature,and the abundance and height of the plant configuration has an influence on the humidity,and its density and degree of enclosure have an influence on the wind speed.The richness and height of plant configuration have influence on humidity,and its density and degree of enclosure have influence on wind speed.
