Research On Space Optimization Of Taixiangsi Village In Yanchuan County Under The Target Of Wind Environment Improvement

After hundreds of years of development,traditional villages have created a place suitable for human living in the harmonious coexistence of man and nature.The local microclimate formed by itself plays a role in regulating the wind environment.A good wind environment can create a stable thermal and physical environment in the village,reduce building energy consumption,reduce the load on the ecological environment,improve ecological conditions,and form a virtuous circle.However,with the rapid development of my country’s economy,people’s living standards have gradually improved.More and more traditional stone hoop kiln villages in the loess hilly and gully areas of northern Shaanxi have carried out a large number of construction activities.The long-term disorderly construction has caused their wind environment to be affected.Destroyed,the quality of the human settlement environment is reduced,and the quality of space cannot be guaranteed.Starting from the assessment of the current quality of the wind environment,this paper analyzes the spatial reasons for the wind environment problems in the typical traditional Shiguyao village—Taixiangsi Village,and tries to solve the problem through space optimization,and finally achieves the purpose of improving the wind environment of the village.The article first establishes the relationship between Taixiangsi Village’s space and wind environment improvement from the aspects of climate characteristics,geomorphic features and construction status,and then conducts field investigations on the spatial pattern and wind environment of Taixiangsi Village,and sorts out the basic situation of the village’s spatial pattern and wind environment..Secondly,the village space model was constructed based on the survey data,and the village wind environment was simulated and evaluated through CFD numerical simulation,and the spatial causes of wind environment problems were analyzed.It was found that there were uncomfortable wind environment areas on the north and south sides of the village in spring,and the south side of the village in summer,autumn and winter.Wind environment is not comfortable area.Furthermore,in view of the wind environmental problems and spatial reasons in Taixiangsi Village,we put forward optimization strategies at different levels in terms of village layout,building clusters and courtyard organization,and carried out a specific analysis of each strategy based on the spatial characteristics of Taixiangsi Village,and concluded that it is suitable for Taixiang Temple.Si Cun’s optimization strategies and methods.Finally,the proposed optimization strategy is used to adjust the spaces with wind environment problems in the four seasons of Taixiangsi Village in spring,summer,autumn and winter one by one.It provides scientific judgment for optimizing the space of traditional Shiguyao villages,and also provides a case for the application of mature urban wind environment simulation technology in the improvement of rural human settlements.The main conclusions of the study: First,the spatial layout of Taixiangsi Village is closely integrated with the topography and landforms,and the surrounding natural environment is reasonably used to fight against the unfavorable climate environment.However,due to the continuous development and construction of the village,there are still wind environment problems in some areas.On the south side of the village,the slopes are small in the foothills,and the residential houses are densely distributed,while on the north side of the village,the slopes are steep and the terrain is complex.In the absence of shelter,local areas have excessive wind speeds in spring.The second is to make local adjustments of spatial elements for the space where wind environment problems occur without changing the overall style of the village,including adding windbreak forest belts at the village level,dredging the boundary space,and optimizing the node space;building a continuous interface and optimizing the group form at the building cluster level;At the courtyard organization level,adjust courtyard layout and optimize courtyard size.The results show that reasonable fine-tuning of the current space of Taixiangsi Village can effectively improve the wind environment of the village.
