| 摘 要： | 对岷江上游干旱河谷荒坡植物群落结构及其多样性进行研究,结果表明:岷江上游干旱河谷荒坡植物群落物种贫乏,α多样性指数波动幅度均较小,各样地植物群落在物种组成和结构上差异均不明显.因此,必须加强其生物多样性保护研究,保护这些半荒漠地区有限的植物资源. |
| 关 键 词： | 物种多样性 群落结构 荒坡 干旱河符 岷江上游 |

| Abstract: | In the barren hillsides of the arid valley of the upper reach of the Minjiang River,the community structure and species diversity were studied.The data displayed that higher plants were very poor,the species diversity was very low and the difference of the community structure and species diversity were not apparent.It should be carried out as soon as possible to protect the plant resources and the biodiversity. |
| Keywords: | species diversity community structure barren hillsides arid valley the upper reach of Minjiang River |
