对海南岛尖峰热带树木园保存的降香黄檀、印度紫檀，海南石梓，黄籽孔雀豆、柚木、麻楝、细基丸、千张纸，乌墨、白格、圆果象耳豆、华楹、黑格、非洲楝和大叶档花心木１５个树种与温度、雨量、日照等的环境因子的关系进行了分析，运用多元统计分析的方法，揭示出了对主要物候期影响最大的气象因子是日平均温度、雨量和日平均日照时数，运用系统聚类的方法将１５个树种各物候期分类，其类型确定为：展叶期、开花期、果熟期和叶变色期

Study on Phenology of Some Tree Species Grown in the Tropical Arboretum at Jianfengling of Hainan lsland

The relationships between the phenology of fifteen tree species grown in the Tropical Arboretum at Jianfengling of Hainan Island and some meteorological factors such as temperature,rainfall,sunshine,etc. were analyzed by using the multivariate statistical analvsis. Results showed that the most important meteorological factors influencing the phe-nological periods of the tree species were mean daily temperature,rainfall and mean daily sunshine. Through using the clustering analysis,the leaf expansion period,the flowering period,the fruit maturing period and the leaf discoloring period were divided into four types respectively.
