摘要
以沈阳市7种常用园林植物为试验材料，采用Li-6400便携式光合测定系统，对不同植物固碳量及碳汇功能进行比较分析。结果表明：7种常用园林植物的单位叶面积固碳量8.32-17.36 g·m^-2d^-1，年固碳量8.70-270.60 kg；7种树种碳汇能力排序为蒙古栎＞银中杨＞水曲柳＞油松＞榆叶梅＞红瑞木＞连翘。碳汇能力聚类分析表明，乔木（4种）分为两级，灌木（3种）分为两级。为提高城市绿地碳汇功能，应选择碳汇能力强的植物。
Seven kinds of common garden plants in Shenyang city were selected as the tested materials, theirifxed carbon contents and carbon sink functions were comparatively studied by adopting a Li-6400 photosynthesis system. The results are as follows. The seven plants’ daily carbonifxation amounts of per unit leaf area was in the range from 8.32 to 17.36 g·m^-2d^-1. The yearly carbonifxation of one plant ranged from 8.70 and 270.60 kg. The carbon sink ability of the seven plants ranked from big to small was as follows： Quercus mongolica〉Populus alba×P.beriliensis〉Fraxinus mandschurica〉 Pinus tabulaeeformis〉Prunus triloba〉Forsythia suspensa〉 Cornus alba. According to cluster analysis results, the carbon sink capacity of 4 arbors were divided into two levels, 3 shrubs divided into two levels. Therefore, in order to raising the carbon sink capacity of urban green space, the plants which have high capacity of carbon sink should be selected and applied.
