摘 要:通过1200m2标准样地调查,研究福建龙栖山自然保护区锥栗群落各种群的分布格局,结果表明:在乔木层的10个优势种群中,除马尾松符合随机分布外,其它种群均符合聚集分布;灌木层的10个优势种群均符合聚集分布;草本层和藤本植物的大部分种群均符合聚集分布,少有随机分布 这主要与物种的生态生物学特性和种群间的竞争排斥有关。The spacial distribution patterns of dominant species in Castanea henryi community in Longqishan, Fujian, China were studied by sampling plot inquisition with an area of 1 200 m^2. The spatial patterns of 10 dominant tree populations, except Pinus massoniana which exhibits random dispersion, conform to aggregated distribution; In shrub layer, all of ten shrub populations conform to aggregated distribution; The great mass of populations conform to aggregated distribution in herb layer as well as in vine layer, the rest of the populations conform to random distribution. The patterns not only were closely related to the ecological and biological characteristics of each species and relationships of competitive exclusion among them, but also to the environment.
