| 摘 要： | 2008年对海北牧业气象站附近的草甸化草原植物群落特征及生物多样性进行了监测和研究。结果表明，研究区内群落的组成成分单一，植物种类比较贫乏，主要植物有23种，隶属9科，21 属，主要优势种为西北针茅（Stipa krylovii）；次优势种为矮嵩草(Kobresia humilis)、冷地早熟禾(Poa crymophila)等。北温带分布的属占优势植物群落，其生活型多年生植物占绝对优势，尤其是多年生非禾草类植物是群落的主要生活型；群落垂直结构不太明显，大体分3层；从物种多样性分析看，4条样线中，物种丰富度指数（R1、R2）、Shannon Wiener指数(H)、Simpson指数(D)及匀均度指数（E1、E2）变化差异不显著（P>0.05），表现出基本一致的变化趋势。 |

| Abstract: | A field survey was conducted to investigate the community characteristics and plant species diversity of meadow grassland in the northeast of Qinghai Lake during 2008.This study showed that 29 plant species were identified in the plot,which belongs to 9 families and 21 genera,indicating that species composition of meadow grassland was simple.The dominant specie was Stipa krylovii and the subdominant species were Kobresia humilis and Poa crymophila.The genus of the north temperate was absolutely dominant,and... |
