Study On Landscape Design Of Urban Wind Tunnel

At present,China is in the stage of high-speed urban development.The vigorous economic development,blind urban development stations and expansion have brought unprecedented pressure on the natural ecological environment,and have also brought many environmental problems,especially the city's underlayment.The surface area is getting rougher,which has brought great blockage to the city's ventilation.This article carries on the research and the discussion to these questions,and makes some discussion and the preliminary optimization design to the urban wind tunnel scenic area.Urban ventilation corridors can not only provide citizens with a limited public space for recreational activities,but also serve as an important part of optimizing urban air quality.It can make the city "breathe",on the one hand,the air flows smoothly into the city,and on the other hand it accelerates the exchange of air between the city and its surroundings and within the city.Based on the research of relevant theoretical experience at home and abroad,on-line data collection,on-site field surveys,etc.,the paper has carried out some classification planning integration of urban ventilation corridors,and carried out some basic research and later optimization design;Strengthen the rational planning and management of urban forms and spatial elements such as buildings,roads,parks,green spaces,open spaces,and water bodies and water systems,so as to promote the evacuation and infiltration of natural winds,and strengthen the ability of air convection,exchange,and purification within the city.Improve the urban air environment and alleviate urban smog and heat island effects.When studying the landscape of urban wind tunnels,take Xi ' an as an example to investigate the area that is likely to be a landscape of wind tunnels in Xi'an.And according to the definition,it is divided into a class II and a potential wind landscape area,and the actual investigation found some advantages and disadvantages of the existing landscape,and at the same time,carried out some detailed anatomical analysis for the optimization of the later stage.In this paper,the experience of domestic and international advanced urban air ducts isalso summarized and analyzed.At the same time,with reference to their experience in the renovation of landscape greening,they are applied to the possible construction of the air duct area in Xi'an in the future,and some Xi'an were made at the end of the article.The current status of the city's wind tunnel research and analysis,as well as some of the views of the transformation of optimization programs.Finally,on the basis of theoretical and practical investigations,we try to implement an operability-optimized treatment for the overall existing plan,making it a truly meaningful ventilation corridor landscape.
