中文摘要：

选择青岛市城阳区11种主要地被植物，利用Li-6400使携式光合测定系统进行了光合生理生态指标的测定，对其固碳释氧与降温增湿效应进行了量化研究。结果表明，11种地被植物的固碳释氧量较高的有火棘、黄花鸢尾、鸢尾，较低的有金叶女贞、五叶地锦和大叶黄杨。降温增湿能力较高的有五叶地锦、金银花、金焰绣线菊，较低的有金叶女贞、大花萱草、鸢尾。

英文摘要：

The physiological indices of eleven widely used ground cover plants in Chengyang district of Qingdao city were tested by Li - 6400 photosynthesis testing system. Furthermore, the carbon - fixing, oxygen - releasing, temperature - reducing and humidity -increasing effects of these plants were studied. The results indicated that Pyracanthafortuneana, Iris pseudoacoru, Iris tectorum had better carbon - fixing and oxygen - releasing effects, while Ligustrum quihoui floridum, Parthenocissus quinquefolia, Euonymus japonicus had worse carbon - fixing and oxygen - releasing effects. Parthenocissus quinquefolia, Lonicera japonica, Spiraea xbumalda cv. coldfiame had higher cooling and humidification ability, while Ligustrum quihoui floridum, Hemerocallis middendorffii, Iris tectorum did not act as well as them.
