摘　　要：文章以哈尔滨市绿化树种为研究点,从绿化树种的叶面积指数、固碳释氧、降温增湿等方面研究了49种生长良好的绿化树种的生态功能,通过研究得到银中杨、榆树、糖槭、杜松、野梨是平均叶面积指数前5位的乔木树种,珍珠梅、接骨木、绣线菊、金银忍冬、天目琼花是平均叶面积指数前5位的灌木树种;榆树、文冠果、火炬树、糖槭、银中杨为年固碳释氧量前5位的乔木树种,黄刺玫、紫丁香、接骨木、树锦鸡儿、榆叶梅为年固碳释氧量前5位的灌木树种;年释水量前5位的乔木树种是文冠果、银中杨、火炬树、榆树、山丁子,年释水量前5位的灌木树种是绣线菊、黄刺玫、毛樱桃、珍珠梅、榆叶梅。Afforestation tree species of Harbin were studied in the paper, ecological functions of 49 well-grown tree species were analyzed in terms of leaf area index, carbon fixation and oxygen-releasing capacity. It was found that Populus alba × p. berolinensis, Ulmus pnmila, Acer negundo, Juniperus rigida and Pyrus ussuriensis were the top five arbor trees in average leaf area index, while Sorbaria sorbifolia, Sambucus williamsii, Spiraea sp., Lonicera maackii and Viburnum sargeantii were the top five shrubs. Ulmus pumila, Xanthoceras sorbifolia, Rhus typhina, Acer negundo Populus alba × p. berolinensis were the top five arbors in annual carbon fixation and oxygen-releasing capacity while Rosa xanthina, Syringa obalata, Sambucus williamsii, Caragana sibirica Prunus triloba were the top five shrubs. Xanthoceras sorbifolia, Populus alba × P. berolinensis, Rhus typhina, Ulmus pumila, Malus baccata were the top five arbors in annual water-release while Spiraea sp., Rosa × anthina, Prunus tomentosa, Sorbaria sorbifolia, Prunus triloba were the top five shrubs.
