| 摘 要： | 调查了甘肃省天祝县珠芽蓼高寒草甸,结果表明,调查草甸的主要植物有26种,隶属13科23属。其中珠芽蓼(0.148)为优势种,次优势种有乳白香青、球花蒿、线叶嵩草等。通过对珠芽蓼草甸群落组成和结构的季节动态的研究分析发现,地上植物量在整个生长季中表现为单峰曲线,地下植物量变化呈现“V”型曲线,环境因子是制约珠芽蓼草甸植物生长发育和植物量的主导因子。

| Abstract: | The community of polygonum vivipatum steppe meadow in Tianzhu Alpine region was analyzed by investigating plant species composing and biomass seasonal change.The results show there are 26 plant species,belong to 23 genera and 13 families,in the Polygonum viviparum steppe meadow,In which dominant species is Polygonum viviparum,then Anaphalis lactea,Artemisia smithii,Kobresia capillifolia,etc.;the aboveground biomass of the plant show "unimodal" type curve tendency,and the underground biomass presented "V" type curve tendency in growing season;environmental factors is closely related to the change tendency. |
