| 摘 要： | 测定了哈尔滨市区3种不同类型绿地与野外紫椴的叶面积指数、固碳释氧、降温增湿、杀菌滞尘、吸收SO2及重金属量,并应用层次分析法对不同环境下紫椴的生态功能进行了比较。结果表明野外和公园绿地的紫椴生态功能指标比较接近,某些指标例如固碳、释氧明显高于防护绿地和附属绿地。公园绿地杀菌率明显高于其他环境,防护绿地对SO2的吸收最高。各种绿地单位面积的各指标值变化规律与单株指标值并不相同,甚至截然相反,这主要是由叶面积指数、冠幅等的较大差异造成。对生态功能的综合评价显示,单株生态功能野外最强,公园绿地稍差,防护绿地和附属绿地功能指数明显较小。单位叶面积生态功能几乎相反,防护绿地最强,附属绿地稍差,公园绿地和野外明显较小。这说明防护绿地和附属绿地的紫椴生态功能相对低主要由于叶面积较小造成,如果通过加强栽培管理等措施,提高生活力,增大叶面积,紫椴在此2种城市环境中的生态功能还有巨大的提高空间。

| Abstract: | Ecological functions of Tilia amurensis growing in different urban habitats were compared by using hierarchy analysis though measuring leaf index,capabilities of carbon fixation and oxygen releasing,reducing temperature and increasing humidity,antimicrobial activity and absorption of sulfur oxide and heavy metals.The results showed that the indices of ecological function of wild T.amurensis populations and those planted in the park were similar.Some indices of ecological functions of T.amurensis,such as car... |
