闽楠群落种间关联性的灰色系统理论分析

应用灰色系统理论的关联度分析方法对福建省罗卜岩自然保护区闽楠Phoebe bournei群落中10种主要优势乔木、10种主要优势灌木及闽楠与灌木的种间关联系数进行测定。结果表明：优势乔木种间关联系数都大于0．5，闽楠与主要灌木伴生树种浙江红山茶Camellia chekiangoleosa，赤皮Styrax suberifolia，狗骨柴Tricalysia dubia，毛冬青Ilex pubescens，绒毛润楠Machilus velutina，短尾越橘Vaccinium carlesii的关联系数都大于0．6。这与群落中的现实情况相似，说明应用灰色系统理论的关联度分析测定群落种间关联性具有可行性。表3参12

Study of inter-specific correlation of Phoebe bournei communities by grey systems

The inter-specific association modulus of 10 dominant tree species, 10 dominant shrub species, Phoebe bournei and shrub were studied by the correlation analysis of grey systems. The result showed that all the inter-specific correlation modulus of tree were more than 0.5, the inter-speclflc association modulus between Phoebe bournei and Camellia chekiangoleosa, Styrax suberifolia, Tricalysia dubia, Ilex pubescens, Machilus velutina, Vaccinium carlesii were more than 0.6. The result was in accord with the facts of the real community. It indicated that the study of the inter-specific correlation modulus by grey systems was feasible. Ch, 3 tab. 12 ref. ]
