摘　　要：以山杜英、云南拟单性木兰、天竺桂、云南樟4种昆明市常用的城市绿化树种为研究对象,分别对其林木的蒸腾速率、水分利用效率、放氧量、降低太阳光直射能力、滞尘能力、改善土壤质量能力和降低大气降水污染的能力进行了测定,以求比较其城市绿化的生态功能。研究结果表明,4种树种的林木都具有良好的生态功能,但各树种林木的生态功能不尽相同。The ecological functions of four urban greening tree species named Elaeocarpus sylvestris, Parakmeria yunnanenzis, Cinnamomum japonicum and Cinnamomum glanduliferum were studied by examining their transpiration rate, water use efficiency, the production amount of O2 , capability of decreasing sunshine beat, dust catching efficiency, ability to improve soil quality and ability to decrease the atmosphere pollution. The results of study indicated that four plant species all had promising ecological effect, and the ecological function of the four species varied and had different characteristics.
