以青海省海南州贵德县拉鸡山地区植物群落为研究对象，从海拔3100—3920m，划分为9个海拔梯度，研究了植物生物量及物种丰富度沿海拔梯度的变化特征。结果表明：阳坡地上生物量与物种丰富度呈极显著正相关关系（r=0．564。P〈0．01），总生物量与根冠比呈极显著正相关关系（r=0．714，P〈0．01）；海拔与地上生物量呈极显著负相关关系（r=-0．773，P〈0．01），与地下生物量、总生物量、根冠比呈极显著正相关关系（r=0．769、r=0．753、r=0．692，P〈0．01）。阴坡植物群落总生物量与地上生物量之间呈显著正相关关系（r=0．495，P〈O．05），与地下生物量之间成极显著正相关关系（r=0．960，P〈0．01），与海拔呈极显著负相关（r=-0．519，P〈0．01）；根冠比与地上生物量呈极显著负相关关系（r=-0．631，P〈0．01）。地上生物量与海拔呈极显著负相关（r=-0．678，P〈0．01）。

The plant community in the area of Laji Hill in Guide county of Hainan prefucture, Qinghai province was regarded as investigation object to study the change characters of plant biomass and species abundance degree with elevation in the nine elevation step divided from elevation of 3 100 meters to elevation 3 920 meters. The results showed that there was the very significant positive correlation between above -ground biomass and species abundance degree in the sun sloping field （ r = 0.564, P 〈 0.01 ） and between total biomass and the ratio of root cap （ r = 0.714, P 〈 O. 01 ）, There was the very significant negative correlation between elevation and above, growhel biomass,and there was the very significant positive correlation between elevation and under- ground biomass total biomass,ratio of root cap（ r =0.769 ,r =0. 753,r =0. 692,resp,P 〈0. 01 ）. There was the significant positive correlation between total biomass and above- ground biomass（ r =0.495 ,P 〈0.05 ） and between total biomass and under - ground biomass （ r =0. 960,P 〈0.01 ） and there was very sigmificant negative correlation between total biomass and elevation （r = -0. 519 ,P 〈0. 01 ） and between ratio of root cap and above- ground biomass （r = -0.631 ,P 〈 0.01 ） and between above -ground biomass and elevation（ r = -0.678 ,P 〈0.01 ） in the shode plant community.
