Study On The Effect Of Different Green Space On Human Comfort

In this study,the following studies were carried out in Hefei City,which has specific climatic conditions and urban morphology:1.In a typical city of Anhui Agriculture University campus,Xiaoyaojin Park and Xinghua park parks for example,were investigated on the selection of various types of green space,used by people on the microclimate characteristics of high density monitoring,the data of multiple comparison(Duncan)analysis and ANOVA(one-way ANOVA);2.Study on the common green space with different canopy temperature,humidity,wind speed and other factors on the micro climate change characteristics,comparison of different density of green space system cooling and humidifying effect and its effect on improving the environment,regulating human comfort;3.On the waterfront and green water far similar to other environmental factors,temperature,humidity,wind speed and other factors on the micro climate change characteristics,comparison of two kinds of green space system in the cooling and humidifying effect and its effect on improving the environment,regulating human comfort;4.The influence of the pavement area on the temperature and humidity of the forest area,which is similar to the plant canopy and close to canopy density,was investigated;5.In the small scale,the canopy density is close to that of the canopy,and the diurnal variation characteristics of the microclimate factors are analyzed.6.The study found:(1)Through the comparative analysis of temperature and humidity change characteristics of 3 kinds of different density of green space,found significant differences in air temperature and humidity in different canopy density of the green forest,sparse forest,compared with lawn,the daily average temperature were decreased(2.27 + 1.67),C(1.42 + 1.58)C;the average daily air the relative humidity was increased(3.42 + 2.2)% and(5.14 + 3.2)%;the average human body comfort index were decreased(1.29 + 2.22),(2.45 + 2.20).The study confirmed that the forest had the highest comfort,sparse forest and grass comfort.(2)Through a comparative analysis of water and water from the lawn lawn of the diurnal variation of temperature and humidity and temperature difference,find the whole point only significant differences in the 9:00-11:00(P < 0.05),relative humidity only in 11:00-13:00 significantly(P < 0.05).Water the lawn of the daily average temperature is reduced compared with the water from the lawn(0.77 + 1.13)C,daily average relative humidity increase(2.45 + 5.27)%,the average human comfort is reduced(0.59 + 0.49).(3)In the shade of trees,there is no direct contact with the solar radiation due to the lack of water surface.Compared with the space area of 60% to 30% of the area of pavement pavement under forest space under the forest,the daily average temperature decreased(0.68 + 0.57)C,daily average relative humidity increase(2.94 + 1.57)%,the average human comfort index decreased(0.43 + 0.52).(4)Through a comparative analysis of 3 kinds of enclosed space green space of the temperature and humidity characteristics of diurnal variation and differences found significant differences in air temperature and humidity in different enclosed space green space,compared to the relatively closed space under the forest,two open enclosed space(branch point lower woodland B and the branch point higher woodland A)average temperatures were lower(0.9 + 1.1),C(0.93 + 1.14)C,daily average relative humidity decreased(0.06 + 3.47)% and(3.57 + 3.35)%,the average human comfort index decreased(1.29 + 1.42),(2.04 + 1.08).Based on the summary of the research results,some feasible suggestions are put forward for the construction of urban green space.
