摘　　要：以银川市三种常见的绿化树种为材料,利用LCi便携式光合仪系统进行了光合生理生态指标的测定,对其固碳释氧和降温增湿效益进行了量化研究。结果表明:三种植物的固碳释氧能力由强到弱依次为紫荆、紫藤、五叶地锦,降温增湿效益由强到弱依次为紫荆、五叶地锦、紫藤。This paper took three commonly used tree species in Yinchuan City as materials,using a portable LCi photosynthesis apparatus to test physiological indices to evaluate the ability of carbon fixation,oxygen release,temperature and humidity regulation.The results showed that the ability of carbon fixation and oxygen release of the 3 tree species were different,and the rank from high to low was Cercis chinensis Bunge,Wisteria sinensis Sweet,Parthenocissus quinquefolia L.But the rank for the ability of temperature and humidity regulation was Cercis chinensis Bunge,Parthenocissus quinquefolia L,Wisteria sinensis Sweet.
