摘要
以哈尔滨市具有地域文化特征的城市公园绿地为研究地,筛选23种常用园林植物作为试材,测定叶片瞬时净光合速率和瞬时蒸腾速率,研究了23种常用园林植物的固碳释氧量和降温增湿量,并用GGE双标图作验证性和综合性评价,以期为打造具有地域文化特色的城市公园绿地植物选择提供参考依据。结果表明:单位土地面积固碳释氧和降温增湿能力乔木大于灌木,阔叶大于针叶;GGE双标图分析得出哈尔滨音乐公园是鉴别树种生态效益最佳的样地;白桦、银中杨和紫叶李对公园绿地环境变化敏感,是适应性最强的树种;筛选出13种生态效益稳定性最佳的树种,分别是银中杨、丛生白桦、东北连翘、紫叶李、榆树、蒙古栎、金叶榆、茶条槭、胡桃楸、旱柳、丹东桧柏、山杏、李子。
Twenty-three species of common garden plants were selected as experimental materials to measure instantaneous net photosynthetic rate and instantaneous transpiration rate of leaves in urban park green space with regional cultural characteristics in Harbin.The carbon sequestration,oxygen release and cooling and humidification of twenty-three common garden plants were studied and evaluated by GGE biplot,in order to provide reference for the selection of plants in urban parks with regional cultural characteristics.The results showed that the capacity of carbon sequestration,oxygen release,cooling and humidification per unit land area was greater for tree than shrub,and broadleaf than conifer.GGE biplot analysis showed that Harbin Music Park was the best sample plot to identify the ecological benefits of tree species.Betula platyphylla,Populus alba ‘Berolinensis’,Prunus cerasifera Ehrhar.‘Pissardii’were the most adaptable tree species,which were sensitive to environmental changes in park green space.Thirteen species with the best ecological stability were selected,which were Populus alba ‘Berolinensis’,Betula platyphylla,Forsythia mandshurica,Prunus cerasifera Ehrhar.‘Pissardii’,Ulmus pumila,Quercus mongolica,Ulmus pumila ‘Jinye’,Acer ginnala,Juglans mandshurica,Salix matsudana,Sabina chinensis ‘Dandong’,Prunus armeniaca,Pruns salicina.
