Abstract:

以拉萨河谷达孜县新仓村沟域的山地灌丛草地为研究对象,采用样方调查法探究了随海拔升高(3992~4940m)灌丛草地群落结构、物种多样性、功能性状Rao指数的变化特征。结果表明,1)随海拔升高灌丛生物量和盖度呈先增加后降低的变化趋势,但草地盖度(71±14)%和生物量(49.18±19.17)g/m2变化不明显(P>0.05);2)随海拔升高群落物种组成存在差异,但共优种高山嵩草(0.591±0.034)和青藏苔草(0.326±0.061)的优势度无显著变化(P>0.05);3)随海拔升高草地物种丰富度、Shannon-Wiener多样性指数呈先增加后降低的“单峰曲线”变化特征;4)以株高测算的草地群落功能性状Rao指数随海拔升高而降低。物种丰富度、功能性状以及地上净初级生产力沿海拔升高的变化特征存在差异,为维持高原河谷山地灌丛草地的生态安全,未来应重视三者相互关系及其生态学机制的相关研究。
