- 摘要:
- 赤水河是我国生物多样性较丰富的地区之一,为了准确可靠地掌握赤水河中段清香木群落生物多样性信息。对赤水河流域中段沿着海拔(445~933 m)高度选择典型清香木天然分布区设置7块20 m×20 m样地,采用相邻格子法调查,进行物种优势地位、物种丰富度、物种多样性指数和群落均匀度分析。结果表明:1)灌木层中主要优势群落为清香木群落,其次是华西小石积群落,物种丰富度较小,即调查到共有56个物种,其中木本植物有42个,草本层仅有14个;2)灌木层中物种丰富度、物种多样性指数明显大于草本层;3)灌木层中Sirnpson指数平均为0.827 0,ShannonWiener指数平均为2.054 8,均匀度平均为0.793 9、0.899 7,说明多样性指数偏低。
- Abstract:
- Chishui River is rich of biodiversity in the region,in order to accurately and reliably grasp the middle of the Chishui River community biodiversity information of Pistacia weinmannifolia,along the Chishui River in the domain of altitude (445~933 m) highly,taking seven distribution typical of natural Pistacia weinmannifolia plots of 20 m×20 m,using contiguous grid survey method,the dominance of species,species richness degree,species diversity index and evenness were analyzed.The results showed that 1)The main advantage of the shrub layer was Pistacia weinmannifolia,followed by the Osteomeles schwerinae, species richness was small,56 species were investigated including 42 woody plants and only 14 herbaceous layers.2)Shrub layer,species richness and species diversity index were significantly greater than the herbaceous layer;3)Shrub layer Sirnpson average index was 0.827 0,ShannonWiener index was 2.054 8,average evenness was 0.793 9,0.899 7,which indicated a low diversity index.
