摘　　要：为了探明澳门松山市政公园群落的物种组成和种间关系,在对其群落进行样方调查的基础上,利用方差比率法、χ2检验以及种间关联度指数对物种关联性进行了分析。结果表明:澳门松山市政公园群落内共有维管束植物119种,其中乔木34种,灌木44种,藤本植物18种,草本植物23种。该群落内物种整体关联性表现为显著的正关联;55个优势种组成的1485对种对中,有242对表现出显著或极显著关联性。其中有241对种对表现出正关联性,占所有关联对数的99.59%,占总种对数的16.23%;仅1对种对表现出负关联性占所有关联对数0.41%,占总种对数的0.067%。In order to clarify the species composition and interspecific association of the forest community in the Guia Hill Municipal Park of Macao based on the investigation of the park, a series of techniques, including the analysis of variance, X^2 -test, Ochiai＇s coefficient （OI）, Dice＇s coefficient （DI）, Jaccard＇s coefficient （JI）, point correlation coefficient （PCC） and association coefficient （AC）, were used to analyze the association of the species in the park. There were 120 vascular bundle species in the park. There are 34 species of arbors, 44 species of shrubs, 18 species of lianas, 23 species of herbs. The overall correlation of all species was significant positive. There were 1485 species-pairs, which were composed by 55 dominant species and checked by X^2 -test. Among these, the inter-specific associations of 242 species-pairs were significant or very significant. Of these, 241 species-pairs showed a significant positive correlation, accounting for 99.59% of all species-pairs and 16.23% of the species-pairs with a significant correlation. While I species-pair revealed a significant negative correlation, accounting for 0.41% of all species-pairs and 0.067 % of the species-pairs with a significant correlation.
