Outdoor Greening Strategy Research Based On Human Thermal Comfort Improvement

With the development of economy,people's requirements of living environment comfort is growing higher and higher.The outdoor thermal environment affects people's daily activities and even healthy.Green system is most important influence factor on outdoor thermal environment and human thermal comfort.It can play the role of shading,cooling,humidification,and noise isolation.But at present,People pay less attention to the thermal comfort of the environment in the process of landscape design or transformation.The article will take the human body thermal comfort improvement as the premise,and will discuss the green system's positive effect on the thermal environment.In this paper,the corresponding strategies for landscape design(especially green design)are proposed.So it will be studied from the following three aspects.Firstly,the paper determines the the influence of the greening system and the green plants on the thermal environment through the measurement and analysis of the outdoor greening environment.Taking urban green space as the research object,the author measured data in Beijing,Shanghai and Qingdao.Taking Beijing as a key case,the article measures the data of areas of different greening rate.The physical parameters of the test include light intensity,air temperature,relative humidity,wind speed,heat flux and negative oxygen ion.Based on the measured data,this paper analyzes the influence of different types of green space and different kinds of plants on the thermal environment.Secondly,the article studies the thermal environment of the green design,and determines the role of the plant to improve the thermal environment.The paper shows the positive effect of green plants on thermal comfort improvement from different angles,from the regional thermal environment to the space design,from the space environment to the space composition elements.The article puts forward a plan to adapt to the environment based on the simulation of the physical environment of the site.Then the paper analyses the area space deeply and confirmed that the green design is the most effective means to improve the thermal environment.Finally,the paper puts forward greening strategies which are benefit to improve human thermal comfort,according to the practice of greening and greening design practice.The article studies the following points from the macro to micro: the significance of green,green channel on the regional thermal environment,the impact of small climate on green design,the relationship between thermal adaptation and plant space,plant design and benefits of plant design and thermal comfort improvement.
