摘要
以上海漕溪立交、虹梅立交和莘庄立交3个典型的高架桥阴环境为试点,以上海辰山植物园非高架桥阴环境下种植的同一批植物作为对照,通过测定上海市常用的5种绿化植物叶片的相对电导率、丙二醛、叶绿素、脯氨酸和可溶性蛋白含量等抗性相关生理指标,对不同绿化植物的生理指标进行比较,并采用隶属函数法对5种绿化植物的综合抗性进行评价。结果表明:莘庄立交下环境胁迫程度最重,虹梅立交下环境胁迫程度较重,漕溪立交下环境胁迫相对较轻;综合隶属函数值表现为‘花叶’常春藤>小叶黄杨>麦冬>八角金盘>五叶地锦,说明‘花叶’常春藤、小叶黄杨和麦冬3种绿化植物对高架桥阴环境的适应性比八角金盘和五叶地锦的适应性强。
Taking 3 typical viaduct shade environments of Caoxi overpass,Hongmei overpass and Xinzhuang overpass in Shanghai as the pilot,and the same batch of plants planted in the non viaduct shade environment of Shanghai Chenshan Botanical Garden as the control,the resistance related physiological indexes such as relative conductivity,the content of malondialdehyde,chlorophyll,proline and soluble protein in leaves of 5 commonly used greening plant species in Shanghai were measured.The physiological indexes of different greening plants were compared,and the comprehensive resistance of 5 greening plant species was evaluated by membership function method.The results showed that the degree of environmental stress was the most serious under Xinzhuang overpass,more serious under Hongmei overpass and relatively light under Caoxi overpass.The value of the comprehensive membership function was Hedera helix‘Discolor’>Buxus sinica var.parvifolia>Ophiopogon japonicus>Fatsia japonica>Parthenocissus quinquefolia,indicating that the adaptability of Hedera helix‘Discolor’,Buxus sinica var.parvifolia and Ophiopogon japonicus to viaduct shade environment was stronger than that of Fatsia japonica and Parthenocissus quinquefolia.
