五台山不同海拔梯度草甸植物群落结构及多样性研究
Community Structure and Diversity of Meadow Vegetation along Altitudinal Gradients in Mount Wutai
摘要
Abstract
This study examined subalpine meadows on Mount Wutai in Shanxi Province to elucidate the spa-tial patterns of biodiversity and the mechanisms driving their maintenance along an altitudinal gradient.Indicators including plant community composition,species diversity,and soil physicochemical properties were measured to analyze variation patterns in meadow community structure and diversity along altitudinal gradients.The results showed that Carex lancifolia and Polygonum viviparum were dominant at low and mid elevations,while Kobre-sia humilis became predominant at higher elevations.The relative biomass of Cyperaceae species increased signifi-cantly with elevation,whereas forbs decreased markedly,displaying statistically significant differences across alti-tudes(P<0.05).Species richness at mid-elevation site(E2)was significantly higher than at both low(E1)and mid-high(E3)elevations(P<0.05).In contrast,no significant differences were observed in the evenness index,diversity index,or dominance index among elevations.β-diversity also varied across different altitudinal levels(P<0.05),reflecting distinct community turnover patterns.Further analysis indicated that soil tempera-ture and water content were the primary environmental factors driving changes in plant community composition,while soil pH and carbon and nitrogen nutrients exerted comparatively weaker influences.关键词
