植物改善老旧小区街道风环境模拟研究

Study on the Simulation of Improving Street Wind Environment in Old Communities with Plants of Old Community by Plants

老旧小区建筑密度大,人口多,公共空间狭窄,风速低,通风性差。本文以湿热气候区中静风城市--成都市的老旧小区为例,结合实测数据,建模拟合分析验证模拟软件的可行性,由此进行植物配置、植物空间布局对风环境的优化模拟。研究结果:一是提出了客观科学地验证风环境模拟软件合理性的普适性方法与程序;二是为老旧小区提供了适宜场地需求、节约化、适老化的风环境改善途径。研究结果具有代表性和推广意义。

The old community has high building density,large population,narrow public space,low wind speed and poor ventilation.The paper takes the quiet wind city in the hot and humid climate zone—the old community in Chengdu as an example.Combined with the measured data,it verifies the feasibility of the simulation software by modeling and fitting analysis.Thus,it carries out the optimal simulation of plant configuration and plant spatial layout on wind environment.The results are as follows:firstly,a universal method and program are proposed to objectively and scientifically verify the rationality of wind environment simulation software;secondly,it provides a wind environment improvement way suitable for site demand,economization and aging for the old community.The research results are representative and meaningful for promotion.
