摘　　要：绿色屋顶对缓解城市化的不利影响有着重要意义。天津地区城市化程度高,绿色屋顶发展相对滞后,缺乏绿色屋顶规模性建设的可行性评估及规划方案。该文以天津市南开区为例,选取建筑属性和绿化需求度作为评价标准,建立绿色屋顶适建潜力评估体系。基于GIS和优劣解距离法(TOPSIS)呈现天津市南开区绿色屋顶综合适建潜力空间分布。研究结果表明,南开区绿色屋顶适建面积约5.17 km^(2),适建潜力平均分为0.53,适建潜力呈“北高南低”趋势。南开区共有46个高度适建社区,优先于适建社区开展绿色屋顶建设可更有效地发挥绿色屋顶在改善城市环境方面的作用。Green roofs are of great significance in mitigating the adverse effects of urbanization.The Tianjin area is highly urbanized,but the development of green roofs is relatively lagging behind,and there is a lack of feasibility assessment and planning schemes for the large-scale construction of green roofs.This study takes Nankai District of Tianjin as an example,and selects building attributes and greening demand degree as evaluation criteria to establish a system for assessing the potential of green roofs suitable for construction.Based on GIS and TOPSIS,the spatial distribution of green roofs in Nankai District of Tianjin is presented.The results of the study show that the suitable area of green roofs in Nankai District is about 5.17 km^(2),and the average score of suitable potential is 0.53,and the suitable potential shows a trend of"high in the north and low in the south".There are 46 highly suitable communities in Nankai District,and prioritizing the construction of green roofs in suitable communities can more effectively play its role in improving the urban environment.
