摘要
生态效益是野生地被植物驯化和筛选的一个重要指标。为了筛选出优秀的野生地被植物,运用光合测定的方法对武汉野外收集的31种野生地被植物进行了固碳释氧和降温增湿能力的测定,以此为基础,定量评价31种野生地被植物的生态效益,并进行了强、中、弱3个等级的分类。结果表明,紫花前胡固碳释氧能力最强,半边莲的降温增湿能力最高。在园林植物配置中,建议综合考虑生态环境和园林景观需求,根据需要合理搭配纸质叶和革质叶植物。
Ecological benefit is an important index in introduction and selection of wild groundcover plants. In order to select optimal wild groundcover plants, the level of carbon fixation, oxygen production, temperature decrease and humidity increase in 31 wild groundcover plants were measured using photosynthesis methods in this study. The ecological benefits of 31 wild groundcover plants were evaluated quantitatively and divided into three levels （strong, medium and weak）. The results showed that Angelica decursive had highest capability of carbon fixation and oxygen production, and Lobelia chinensis had highest level of temperature decrease and humidity increase capability. Therefore, it is suggested that plants with papery leaf and leathery leaf might be applied reasonably in the landscape plants configuration for the general demands of ecological environment and garden sight.
