In order to provide scientific basis for the construction of green belts in river corridor,the effects of green belts with different canopy closure density on the temperature and humidity were analyzed by the small-scale of quantitative measurement The results showed that the green belt with different canopy closure density had effect on the decrease of temperature and increase of humidity in spring,summer and autumn; the effects of different belts on temperature and humidity were ranked as order of summer>autumn>spring. The temperature and relative humidity benefits increased with the canopy density of the green belt. The effects of different belts on temperature and humidity were related to ambient temperature. It took place in the period that was the most height temperature in one day (14:00-16:00).The green belt with internal constitution of lawn had effect on the decrease of temperature and increase of humidity in winter.The temperature and relative humidity benefits increased with the canopy density of the green belt.%试验选择北京北五环清河两侧不同郁闭度的绿地作为研究对象,利用小尺度定量测定的技术方法,分析城市沿河绿地不同郁闭度与温湿效应的关系,为河流廊道绿带的建设提供科学依据。结果显示:春、夏、秋三季样地为增湿降温效应,三季降温效应排序为:夏季>秋季>春季;随着郁闭度的增加,增湿降温效应逐渐增强;绿地的增湿降温能力与环境温度变化相关,一天当中,春、夏、秋三季增湿降温效应最强的时段发生在环境温度最高的时段(14:00-16:00);而冬季则表现为保温降湿效应,随着郁闭度的增加,保温降湿效应在逐渐增强。
