| 摘 要： | 在对贺兰山高山草甸进行群落调查的基础上,研究高山草甸生物多样性和地上生物量与环境因子之间的关系,进而分析生物多样性和地上生物量的关系.结果表明:(1)地上生物量主要与土层深度成正相关关系.(2)海拔高度与生物多样性成负相关关系,而其它影响物种丰富度或Shannon指数的环境因子仅在个别群落类型中起作用.(3)生物多样性与地上生物量主要呈单峰曲线关系. |
| 关 键 词： | 物种丰富度 Shannon指数 地上生物量 单峰曲线 |

| Abstract: | Based on the data from 66 plots including 35 samplings of aboveground biomass, the relationship between biodiversity and aboveground biomass was studied in the alpine meadow on Mt. Helan, China. The results indicated: Firstly, the aboveground biomasses were positively correlated with the average depths of soil layers for all sampling plots; secondly, the species richness and Shannon index were both negatively correlated with altitude, while other environmental factors, which could also affect the species richness or Shannon index, could only take effects on few community types; lastly, the response curves of specie richness or Shannon index to aboveground biomass were both unimodal. |
| Keywords: | species richness Shannon index aboveground biomass unimodal curve |
