Research on Environmental Factors and Human Comfort in Canton Orchid Garden
In order to explore the construction of parks suitable for recreational activities in South China,based on the field survey,different landscape zones inside Canton Orchid Garden were selected to monitor the air temperature,relative humidity,anion concentration,air particulate concentration and acoustic environmental factors.Human comfort analysis was also carried out.The results show that Canton Orchid Garden has a significant cooling effect,of which the most obvious area is the orchid garden,followed by the Fanghua Garden and the Mingjingge area,which can alleviate the discomfort of the human body to a certain extent.The average concentration of negative oxygen ions in the Orchid Garden is 689 ions/cm3,and the impact on human health is normal.The average concentration of airborne particulate matter in the orchid garden is about 36.95 μg/m3 for PM2.5 and 76.80 μg/m3 for PM10,and the daily average of the concentrations of PM2.5 and PM10 have reached the national standard of Class Ⅱ.The average daytime sound in Orchid Garden is 60.82dB(A),and only the average daily sound level in Fanghua Park reaches the national daytime ambient sound level 2.The environmental factors in the Canton Orchid Garden are disturbed in many ways,and it is necessary to control the impact of unfavourable conditions on the environmental factors through landscape practices to enhance the quality and effectiveness of recreation in the garden.
