摘要
园林绿地对城市风热环境的改善发挥着重要作用,选取不同空间类型的校园绿地作为研究对象,对广场类、休憩绿地类、建筑中庭类、道路类4种绿化空间的冬季微气候效益进行定量化研究。于2016年12月12-16日,每天8:00-16:00,每2h1次分别对南京林业大学校园内具有代表性的10处样地的温度、相对湿度和风速进行同步测定。结果表明,绿地结构与建筑布局对校园冬季微气候影响最大,水体面积次之,下垫面材料的影响最小。对多数空间而言,在场地西北向或高层建筑下方布置乔-灌-草结构常绿植物构筑风障,东侧群植落叶乔木增加纳阳面积,对冬季微气候环境的改善有显著作用。
Green space plays an important role in the improvement of urban windy and hot environment. In this research, the authors selected different types of campus green spaces as the objects of study,and stud- ied the winter microclimate benefits of four kinds of green spaces, such as squares,leisure green space, atri- ums and roads. During 8：00--16：00,12--16 December, 2016, relative parameters were measured within the campus of Nanjing Forestry University every 2 hours each day,including temperature, relative humidity and wind speed simultaneously on 10 representative locations . The results showed that the structure of green space and the layout of the campus had the greatest influence on the microclimate of the campus in winter. The impact of water area was less. The last was cover material, Using arbor-shrub-grass structure of ever- green plants in the northwest of the site or below the tall building could build windbreaks. Planting grouped deciduous trees in the east could increase the illumination area. These measures had significant effects on the improvement of the micro-climate environment in winter.
