摘 要:为探讨草本植物群落的群落特征与生物量之间的关系,以沈阳市浑河河岸带4种不同生境类型下的草本植物群落为试验对象,采用样地调查法,测定了4种生境下植物群落的海拔、坡度、坡向、郁闭度、高度、盖度、土壤含水量以及生物量等参数,并进行了植物群落特征和生物量之间的相关性分析。结果表明,(1)4种不同生境下的群落类型中,草本植物种类以菊科和禾本科植物为主,各包含15种和11种,分别占物种总数的23.4%和17.2%。在不同群落中,乔草群落下草本植物物种数的占比最高,乔灌草群落下最低。(2)通过测定皮尔逊相关系数可知,不同生境草本植物群落特征与群落生物量之间存在显著的相关关系(P<0.05)。由于海拔、郁闭度和土壤含水量等草本植物生长发育的决定性因素的差异,在不同生境类型群落下草本植物群落的多样化特征对群落生物量存在显著影响。The collected altitude,slope direction,aspect,canopy density,height,coverage,soil moisture content,and biomass data of 4 herbaceous plant communities in the riparian zone of Hunhe River in Shenyang City were studied with typical sample method to determine the relationship between the characteristics of plant communities and the biomass.The results showed that herbaceous plants of four habitat types were dominated by 15 classes of Asteraceae and 11 classes of Gramineae,accounting for 23.4%and 17.2%,and the proportion of herbaceous plant species was highest in the arboreal grass community,and lowest in the arboreal-shrub grass community.Pearson correlation analysis showed that there is a significant correlation(P<0.05)between herbaceous plant community characteristics and community biomass in different habitats.Due to the differences in determinants of herbaceous plant growth and development such as altitude,degree of depression and soil moisture content,the diverse characteristics of herbaceous plant communities had a significant effect on community biomass under different habitat types of communities.
