摘要:
对合肥滨湖湿地公园内的林下植物进行调查,对林下植物的多样性、重要值、生物量进行分析。结果表明,该范围内林下植物共有44种,其中草本类共39种,隶属于23科37属,木本类共5种,隶属于4科4属;林下草本植物中,加拿大一枝黄花重要值最大,为1.41008,为绝对优势种群;林下植物物种多样性指数较低,且分布不均匀,其Simpson 指数、Shannon-Wiener 指数以及均匀度指数的平均值分别为0.5722、1.6700和0.6745;通过对比分析表明,该区域内林下植物受到加拿大一枝黄花影响,导致丰富度较低,且植物群落结构不稳定,与同样受加拿大一枝黄花影响的合肥骆岗机场对照组林下植物进行对比,滨湖湿地森林公园样方内林下植物Simpson指数、Shannon-Wiener指数均高于对比组样地,均匀度指数略低于对比组样地。

Abstract:
In this study, we conducted an investigation of the understory plants in Hefei Lakeside Wetland Forest Park, and analyzed their diversity, important value and biomass. There were 44 species of understory plants, of which 39 species of herb plants belong to 37 genera in 23 families and 5 species of woody plants belong to four genera in four families. The important value of S.canadensis was 1.41008, which was the biggest among the understory herb plants in the park, and it was absolute dominant population. The diversity index of the understory plants was quite low and unevenly distributed. The mean values of Simpson index, Shannon-Wiener index and Evenness index were 0.5722, 1.6700 and 0.6745, respectively. After analyzing these indexes, we found that the richness of the understory plants in Hefei Lakeside Wetland Forest Park was low and its community structure was unstable due to S.canadensis. Compared with the indexes of the understory plants around Hefei Luogang airport(control group, which were also affected by S.canadensis, the Simpson index and Shannon-Wiener index of the understory plants in Hefei Lakeside Wetland Forest Park were higher and only the Evenness index was a little bit lower than the control group.
Key words:  Hefei Binhu Wetland Forest Park  ecological restoration  diversity  community structure  dominant species  invasive alien species  Solidago canadensis
