摘要
以黑龙江省森林植物园为研究对象,分别在3个月份测定了森林植物园和市区几个代表性样点的空气中的CO2浓度、空气的温湿度。结果表明:在5、7、9月份,森林植物园内空气中的平均CO2的体积分数为378×10-6,低于城市区3个月份的平均值399×10-6;3个月份内森林植物园的环境平均温度比市区平均低2～4℃,空气的相对湿度比市区高6.2%～14.2%。森林植物园的热辐射强度平均比市区低达2倍,是哈尔滨市的"天然绿色空调"。
An experiment was conducted to measure atmospheric CO2 concentration, air relative temperature, relative humidity in Heilongjiang Forest Botanical Garden and several sampling sites in tile urban area of Harbin in May, July and September in order to study the carbon-fixed and oxygen-released ability and the function of temperature decrease and humidity in- crease for the plants in different seasons. Result showed that the average atmospheric CO,. concentration in Heilongjiang Forest Botanical Garden in May, July and September was 0. 037 8, a little lower than that in the urban area （0.039 9）. The average air temperature in tile forest garden was 2-4 degrees C lower and the relative humidity was 6.2%-14.2% higher than that in the urban area. The intensity of thermal radiation in the urban area was two times as much as that in the forest garden in summer. The forest garden is a natural air-conditioner in Harbin.
