    摘要:

    以哀牢山中山湿性常绿阔叶林的14个主要树种为材料,研究了树种物候的主要特征,编制了物候谱,考察了树种物候期与温度、光照等环境因子的关系。采用主成分分析方法,揭示出各物候期平均温度和≥5℃积温与树木的物候表现最为密切。对于树木开花期的诱导,光照和温度具有同等重要的作用;但在萌动-展叶期中,降雨量和光照则起主导作用。

    Abstract:

    This paper deals with the phenology of fourteen main tree species in montane humid evergreen broad leaved forest in Ailao Mountains. The main phenological characters of these trees were observed, the phenological spectrum was described and the relationship between the phenological rhythms of the tree species and the environmental factors of light, temperature ect. was investigated. Through the principal component analysis(PCA), it has been discovered that the main meteorological factors, which are most closely related to the phenological performance of these trees, are the mean temperature and ≥5℃ accumulated temperature of different phenological period. The light duration and temperature play an equally important role in the induction of flowering,and in the leafing period, the precipitation and light play a leading role.
