Research On The Green Space Design Of Beijing Winter Park Based On The Analysis Of Human Comfort

With the change of the urban climate,people's behavior has been greatly affected,especially in the cold winter,and the severe climatic conditions have greatly restricted human activities.Urban park green space is an important place for people's outdoor activities.In the current urban park green space design research,attention to climate issues is ignored.Therefore,park green space design research aimed at improving the comfort of citizens' outdoor activities is very necessary.This article takes the park green space in Beijing as an example,conducts field observations and surveys on its winter climate characteristics,explores the relationship between its landscape elements and human comfort,and proposes a method to improve the microclimate of winter park green space in order to provide public space design in Beijing Theoretical support.This article takes three different types of landscape spaces as research objects,through field surveys,instrumental surveys and questionnaires to explore the microclimate environmental characteristics and tourists under different landscape spaces(square space,plant community space and water body)in the green space of winter parks Perceived evaluation of comfort.Quantitative analysis of the effects of spatial environmental factors such as the degree of space enclosure,canopy type,plant configuration,water area and other spatial environmental factors on the comfort of different spaces through the human comfort index DI.It was found that in the cold winter,the solar radiation that affects human comfort on the square is an important factor that attracts tourists to stay on the site.The square covered by the deciduous tree canopy is more comfortable,and the square surrounded by plants has lower wind speed;Plant communities,complex community structures are conducive to wind protection in winter and have a good comfort level.The cross-lattice layout of plants on the plane is conducive to the reduction of wind speed.Tower-shaped evergreen trees should be planted on the outermost periphery of the north side in the vertical direction,such as arborvitae and other plants,and the windproof effect is better.The microclimate effect around the water body does not increase with the increase of the water surface.Taking the Olympic Forest Park as an example,when the water surface rate of the Nanyuan water surface is 5%,the human comfort is better.Finally,through the actual measurement and simulation analysis,this paper proposes a specific optimization strategy to make a certain contribution to the improvement of the comfort level of the winter park green space in Beijing.
