摘要:

应用样地调查法对湖南高望界国家级自然保护区内的野生雪峰山梭罗(Reevesia xuefengensis)群落特征进行了研究,从群落的生境、优势种群的数量特征、群落的垂直结构、种群动态等方面揭示了该群落的基本特征.结果表明,雪峰山梭罗和青冈(Cyclobalanopsis glauca)为该群落的优势种群,因而命名为雪峰山梭罗+青冈群落.群落的垂直结构明显,可分为乔木层、灌木层和草本层,层间植物少.雪峰山梭罗种群的龄级结构呈钟型,具衰退趋势; 青冈种群的龄级结构属增长型,青冈终将取代雪峰山梭罗而形成稳定的顶级群落.建议规划保护范围,实行动态保护管理,加强人工复壮.

Abstract:

Field survey was made on the community characteristics of wild Reevesia xuefengensis in Gaowangjie National Nature Reserve of Hunan Province in terms of habitat, quantitative characteristics of dominant population, vertical structure and population dynamics. The results showed that Reevesia xuefengensis and Cyclobalanopsis glauca were the dominant population in the community, which gave the name to the community as community of Reevesia xuefengensis and the Cyclobalanopsis glauca. The vertical structure of the community was obvious, which can be divided into three layers of arbor layer, shrub layer and herb layer, with less plant between the layers. The age-grade structure of Reevesia xuefengensis population was of bell type with decline tread; while that of Cyclobalanopsis glauca population was increasing. Cyclobalanopsis glauca will eventually replace Reevesia xuefengensis and forms a stable top-level community. The measures of planning protection scope, implementing dynamic protection management and strengthening artificial rejuvenation are put forward.

Key words: Reevesia xuefengensis, community characteristics, Gaowangjie, national nature reserve
