Study On Optimal Design Of Outdoor Wind Environment In Coastal Fishing Village In Northern Qingdao

Coastal fishing village is the carrier of the historical memory of every coastal city,showing the life style of the original inhabitants.The 14 th Five-Year Plan of the People’s Republic of China proposes to strengthen the construction of "beautiful villages".Under the guidance of Qingdao’s strategy of "overall development in the whole region",a number of modern beautiful countryside with beautiful layout,clean and tidy villages and beautiful environment have emerged,which are livable,suitable for business and tourism.However,the coastal fishing village in the north of Qingdao has the disadvantages of single industry,slow economic development,relatively backward village construction,high energy consumption and low comfort.Therefore,it is urgent to optimize the wind environment of the coastal fishing village in the north of Qingdao.In this paper,the wind environment is taken as the starting point of microclimate research in coastal fishing villages,and the coastal villages in northern Qingdao have been investigated on the spot.Taking Buxi Village as the representative,the design strategy for the comfort reconstruction of coastal fishing villages in northern Qingdao has been put forward from the perspective of outdoor wind environment optimization by means of site investigation,field measurement and Fluent software simulation.Firstly,this paper summarizes the research work on the wind environment of villages in China at present,and determines that the factors affecting the wind environment are temperature,humidity and wind speed,so as to provide a technical route for the research.Secondly,through on-the-spot investigation,this paper analyzes the present situation of the coastal fishing village in northern Qingdao,covering the statistics of the village form,road layout,street size,building status and the underlying surface that has influence on the wind environment.On this basis,Buxi Village was selected as the research target village to measure the wind environment data in summer and winter,and the influencing factors of the wind environment in the northern coastal fishing village of Qingdao were extracted.The orthogonal test method was used to construct an experimental scheme including four influencing factors: the permeability of the courtyard wall,the width of the road,the direction of the road,the location of houses and roads.Finally,the Fluent software is used to simulate nine street models designed by orthogonal test method,and the weight of village environmental factors is calculated by using range method,and the wind environment optimization scheme is determined to simulate,and the optimal design strategy for outdoor wind environment of coastal fishing village in northern Qingdao is put forward.Based on the above research results,combining with the characteristics of coastal fishing villages in northern Qingdao,coordinating the wind environment of villages,winter and summer climate characteristics,this paper puts forward the corresponding optimal design methods and strategies of wind environment of villages from the aspect of village spatial form design,and verifies the effectiveness of the optimal design strategies of wind environment through computer simulation technology,which provides theoretical guidance for the construction of coastal fishing villages in northern Qingdao.
