Study On Wind Environment Of Urban Park Landscape Corridor

The 19 th National Congress of the Communist Party of China put forward a series of national strategies,such as strengthening the construction of ecological civilization,building a healthy China and building an ecological corridor.However,most of the current park landscape design focuses on visual beautification,while the wind environment is not considered enough,which easily leads to the park wind environment comfort is not high,and may lead to local bad wind conditions affecting the health of tourists.Through reviewing relevant literature,it is found that wind environment studies are mostly focused on urban buildings and architectural complex environment,and a few scholars have conducted preliminary studies on the importance of park wind environment,the influence of plant specifications and the influence of plaza waterfront space,but few studies on landscape corridor space.Therefore,it is of great significance to study the wind environment of urban park landscape corridor.Aiming at improving the comfort level of pedestrian wind environment in urban park landscape corridors,this study explored the wind speed characteristics of different spatial patterns in park landscape corridors,and improved the comfort level of wind environment inside the corridors by optimizing the spatial patterns.Firstly,the research status of landscape wind environment at home and abroad and the evaluation indexes of outdoor wind environment were sorted out.Through a large number of literatures,the influencing factors of spatial wind environment of park landscape corridor were classified and selected.According to the existing problems of urban wind environment research,the research objects and experimental sites were selected.Secondly,the wind speed measurement and PHOENICS simulation were used to analyze the characteristics of the spatial wind environment of the park landscape corridor,determine the optimization area of the wind environment,and verify the feasibility of the experiment using linear regression.Then,the influence characteristics of wind direction Angle,vegetation spacing,corridor width and plant type collocation on wind speed in landscape corridor were summarized and the relationship among the factors.Finally,based on the above research results,the spatial pattern of the landscape corridor in the experimental site was optimized,and the wind environment design of the park landscape corridor was proposed.This paper emphasizes the importance of wind environment simulation and numerical evaluation in the design stage of park landscape corridor,summarizes the characteristics of different spatial patterns of park landscape corridor on wind speed,and puts forward optimization strategies,in order to provide new ideas and reference for the planning and design of park landscape corridor.
