| 摘 要： | 以青藓(Brachythecium albicans)、大羽藓(Thuidium cymbifolium)、东亚砂藓(Racomitrium japonicum)、鳞叶藓(Taxiphyllum taxirameum)、绢藓(Entodon cladorrhizans)、大灰藓(Hypnum plumaeforme)为材料,与假俭草(Eremochloa ophiuroides)、佛甲草(Sedum lineare)两种常用立体绿化植物作对比,比较了它们的吸水率及其在不同温度条件下的保水性.提出了对水分调节能力的评估方法,获得了8种植物水分调节能力的相对指标.按该指标由高到低,分别是大灰藓(0.821 5)、大羽藓(0.672 7)、青藓(0.546 8)、东亚砂藓(0.532 1)、鳞叶藓(0.528 5)、绢藓(0.437 4)、佛甲草(0.284 3)和假俭草(0.212 6).

| Abstract: | The saturated water absorption and retention rates of six mosses,namely Brachythecium albicans,Thuidium cymbifolium,Racomitrium japonicum,Taxiphyllum taxirameum,Entodon cladorrhizans and Hypnum plumaeforme,were determined and compared with those of Eremochloa ophiuroides and Sedum lineare.An integrated index to evaluate water regulation capacity was proposed.According to the integrated index concerning water regulation capacity from high to low,six moss species were ranked as H.plumaeforme (0.8215),T.cymbifolium (0.6727),B.albicans (0.5468),R.japonicum (0.5321),T.taxirameum (0.5285) and E.cladorrhizans (0.4374).The water regulation capacity of the six moss species were all higher than those of S.lineare (0.2843) and E.ophiuroides (0.2126). |
