Landscape Pattern's Effect On Wind And Thermal Environment Of The Best Town Site In Ideal Fengshui Model

The ideal Fengshui model of Fengshui culture is the important guiding ideology of Chinese traditional city and landscape layout,planning.Each landscape element in ideal Fengshui model occupies an important position,the change of landscape pattern and structure will have a certain impact on the overall environment.This paper takes Sichuan Langzhong area as an example,uses Fluent-Airpak3.0 software to simulate the best town site's wind and thermal environment of the ideal Fengshui model,contrasts and analyzes the influence of landscape pattern changes on the best town site's wind and thermal environment of the ideal Fengshui model under different season conditions,and the research conclusions are as follows:In winter,the existence of Shaozu Mountain and Zhu Mountain can block the invasion of wind,and the height of Shaozu Mountain and Zhu Mountain are below 300m,500m respectively,and the wind speed field of the best town site is more uniform,the insulation effect is better,and people can feel better.The existence of An Mountain and Chao Mountain has effect on internal wind environment of the best town site,but they can play a role in insulation.When the distance between Zhu Mountain and Mingtang Mountain is 100m-200m,the wind and thermal environment of the best town site will be better.In summer,the existence of An Mountain and Chao Mountain also can block the invasion of incoming wind,the low An Mountain and Chao Mountain can make the ventilation effectiveness of the best town site is good,and can reduce the temperature of the best town site.When the height of Shaozu Mountain and Zhu Mountain are below 250m and 450m respectively,the wind and thermal environment of the best town site will be better.When the distance between Zhu Mountain and Mingtang is closer,the wind and thermal environment of the best town site will be better.In summary,the existence of landscape elements like Shaozu Mountain,Zhu Mountain,An Mountain and Chao Mountain and so an is in favor for the best town site to shape a good wind and thermal environment.The ideal Fengshui model enclosed and formed by these landscape elements is conducive to windbreak and warming in winter;and is conducive to ventilation and cooling in summer.Different layout methods also have a certain impact on the wind and thermal environment of the best town site.Therefore,in the location,layout and planning of modern city and landscape,it can refer to the above reasonable layout mode.This study explores the influence of the layout of different landscape elements on the best town site's wind and thermal environment of the ideal Fengshui model,and provides theoretical guidance for the location,planning and layout of the city and landscape in the future.
