摘　　要：应用盆栽试验方法,测定了土壤水分连续变化过程中北方常见藤本绿化树种爬山虎Parthenocissus tricuspidata的光合速率和蒸腾速率,据此计算分析土壤水分条件对爬山虎释氧固碳和降温增湿效应的影响。试验结果表明:在土壤水分条件良好的情况下,生长季节爬山虎可吸收二氧化碳4.71 g.m-2.d-1,释放氧气3.43 g.m-2.d-1,可以使周围1 000 m3空气温度降低0.45℃,相对湿度提高0.39%。随着水分胁迫的加剧,爬山虎固碳、释氧、降温、增湿能力逐渐下降。Leaf photosynthesis and transpiration of climbing plant Parthenocissus tricuspidata in different soil moisture cofiditions were measured to find out the effects of soil moisture on O2 releasing, CO2 fixing, air temperature falling and air humidity increasing. Results showed that Parthenoeissus trieuspidata absorbed 4.71 g·m^-2·d^-1 CO2 and released 3.43 g·m^-2·d^-1 O2 in the favorable soil moisture condition in a day, which reduced air temperature by 0.45 ℃ per 1 000 m^3 and increased air humidity by 0.39 % . With soil water stress increased, CO2 fixing, O2 releasing, air temperature reducing and air humidity increasing of Parthenocissus tricuspidata declined. [Ch, 2tab. 17 ref.]
