不同水景观对室外热环境的改善作用研究

Study on the Improvement of Outdoor Thermal Environment by Different Water Landscapes

为了了解不同水景观对室外热环境的改善作用,以降温幅度和增湿幅度为主要观测内容,研究镜湖、叠水和喷泉3种不同的水景观对周边的温度和湿度所产生的改善作用,并分析不同的风环境条件下,镜湖周边的热环境变化情况。结果表明,叠水和喷泉对其周边环境的影响范围比镜湖大,而风向不同时,下风向的环境温度和湿度得到较明显的改善。风环境在水体改善室外热环境的影响中起到了促进作用。

In order to understand the effect of different water landscapes on the improvement of outdoor thermal environment,taking the range of cooling and humidification as the main observation content,this paper studied the improvement effect of three different water landscapes,Jinghu,Dieshui and fountains,on the surrounding temperature and humidity,and analyzed the change of thermal environment around Jinghu under different wind environment conditions.The results show that the influence range of Dieshui and fountains on the surrounding environment is larger than that of Jinghu.Wind environment plays an important role in the improvement of outdoor thermal environment.
