安徽岳西县鹞落坪国家级自然保护区森林群落结构的初步分析

Preliminary analysis of forest community structure of Yaoluoping National Nature Reserve in Yuexi County, Anhui Province, China

对鹞落坪国家级自然保护区3个1 hm^2样地胸径2 cm以上的个体进行每木调查,并根据乔木层和灌木层物种重要值,将鹞落坪、吊罐井和庵基坪3个样地分别划分为茅栗+山胡椒(Castanea seguinii+Lindera glauca)、化香树+山胡椒(Platycarya strobilacea+Lindera glauca)和化香树+江浙山胡椒(Platycarya strobilacea+Lindera chienii)3种群落类型。三个样地的建群种均为落叶树种,仅在海拔较低的吊罐井样地中分布有常绿树种。吊罐井样地物种数目最多(81个),庵基坪样地次之(76个),鹞落坪样地最少(62个)。该区域群落结构稳定,植被恢复较好。

Three 1-hm^2 permanent plots were established in the Yaoluoping National Nature Reserve in Anqing of Anhui Province. All trees with diameter at breast height（DBH） ≥ 2 cm were mapped, tagged with aluminum plates of unique numbers, and identified by species. On the basis of the importance value of the canopy and shrub layer, the three plots in Yaoluoping, Diaoguanjing and Anjiping were classified as Castanea seguinii ＋ Lindera glauca deciduous broad-leaf forest community, Platycarya strobilacea ＋ Lindera glauca deciduous broad-leaf forest community, and Platycarya strobilacea ＋ Lindera chienii deciduous broad-leaf forest community, respectively. The three plots were all dominated by deciduous trees with evergreen trees only found in the Diaoguanjing plot. The Diaoguanjing plot was most abundant in species（81）, followed by the Anjiping plot（76） and the Diaoguanjing plot（62）. The local plant communites are stable and the vegetation is well restored.
