Abstract

Abstract: Using small-scale quantitative measurements, effects of temperature and humidity on the different vertical structures of green belts along the QingHe River in Beijing were studied to provide practical guidelines for constructing green belts. Results indicated that green belts could decrease temperature and increase humidity in spring, summer and autumn, and had strongest effects on both temperature and humidity in summer. The effects of green belts on both temperature and humidity were related to ambient temperature. The strongest effects of green belts on both temperature and humidity occurred during highest temperatures (between 14:00-16:00) of three seasons. The effects of different green belts on temperature and humidity in spring, summer and autumn were ranked as tree-shrub-herbage>tree-herbage>shrub-herbage>lawn. Tree-shrub-herbage had the strongest effects on temperature increasing and humidity decreasing compared with other tested structures while lawn had an effect on temperature decreasing and humidity increasing in winter. There was little difference between tree-herbage and shrub-herbage in winter.

Key words: Urban river, Green belt, Vertical structure, Temperature-Humidity benefit, Four seasons

摘要： 选择北京北五环清河两侧不同垂直结构类型的绿地作为研究对象,利用小尺度定量测定技术方法,分析城市河流廊道绿地不同垂直结构绿地的温湿效应,为河流廊道绿带的建设提供科学依据。结果表明:春、夏、秋3季具有降温增湿效应,其中夏季降温增湿效应最强,春、秋2季降温增湿效应差别不大;绿地的降温增湿能力与环境温度相关,3季日间降温增湿效应最强时段均在环境温度最高时段的14:00-16:00。春、夏、秋3季不同结构绿地类型降温增湿幅度排序为乔-灌-草>乔-草>灌-草>草地,而冬季绿地除草地外,其余3种绿地均具有保温降湿效应,其中乔-灌-草绿地保温降湿效应最强,乔-草和灌-草型绿地差别不大;草地在冬季表现为降温增湿效应。
