摘　　要：随着城市的不断发展,城市热岛效应日益显著,各种环境问题应运而生,屋顶绿化已被作为提高城市绿地覆盖面积、缓解城市热岛效应、改善城市生态环境的重要手段之一。文章以徐州市老城区二环以内的屋顶绿化为研究对象,以缓解城市热岛效应为研究目标,结合徐州市老城区风环境、热环境空间分布情况以及研究区建筑质量,将屋顶绿化与热环境、风环境、建筑质量等建立联系,在当前有限的经济发展水平条件的前提下,针对热岛效应问题,分析归类出研究区屋顶绿化核心建设区域,再根据不同的建筑环境条件将建筑屋顶分为条件优越型屋顶、条件适宜型屋顶、条件粗放型屋顶,对其分类分级别进行屋顶绿化,试图利用科学合理的屋顶绿化布局来缓解热岛效应、改善生态环境,从而实现资源的最优化配置。With the continuous development of the city,the urban heat island effect is becoming more and more significant,and various environmental problems have emerged.Roof greening has been applied as one of the important means to improve the coverage area of urban green space,alleviate the urban heat island effect and improve the urban ecological environment.In this paper,the roof greening within the second ring of the old town of Xuzhou City is taken as the research object,and the mitigation of urban heat island effect is taken as the research goal.Combined with the spatial distribution of wind and thermal environment in the old town of Xuzhou City and the construction quality of the research area,the roof greening is related to the thermal environment,wind environment and construction quality.Under the premise of the current limited economic development level,the core construction area of roof greening in the research area is analyzed and classified according to the heat island effect.Then,according to different building environment conditions,the building roof is divided into superior roof,suitable roof and extensive roof,and the roof greening is classified and graded.Trying to use scientific and reasonable roof greening layout to alleviate the heat island effect,improve the ecological environment so as to achieve the optimal allocation of resources.
