以五鹿山国家自然保护区的白皮松群落为研究对象,通过典型样方调查,对其物种组成和群落结构进行了研究。结果表明 :样地内植物共有32科45属61种,裸子植物2科2属3种,被子植物30科43属58种; 从物种多度、平均胸径和重要值等指标来看,群 落具有比较明显的优势种; 群落垂直结构复杂,分为乔木层、灌木层和草本层,其中乔木层又可分为3个亚层; 白皮松种群在每 一个乔木亚层中都有出现,是该群落的优势种群; 样地内所有树种的径级结构呈倒“J”形,几种优势种树种的径级结构可分为 3种类型:倒“J”形、双峰形和倒“W”形。
Abstract
The species composition and structural characteristics of Pinus bungeana community of National Forest Park of Wulu Mountain were studied by the sample-plot survey method. The results showed that 61 species belonging to 32 families and 45 genera were recorded in the plots. Among the 61 recorded species, 3 species are gymnosperms belonging to 2 families and 2 genera, 58 species were angiosperms belonging to 30 families and 43 genera. Data on species abundance, mean DBH and important value indicated that the dominant species were obvious within community. The communities had a complex vertical structure and were divided into arbor layer, shrub layer and herb layer. The arbor layer could be divided into three sub-layers. The species group of Pinus bungeana were the dominant population in the community, which appeared in each sub- layer. The size-class structure of all species in the plots generally conformed to a reverse “J” distribution. The size-class structure of several dominant species could be divided into three types: a reverse “J” distribution, bimodal distribution and a reverse “W” distribution.
