After a short introduction to phenology, the complex environmental factors influencing vegetation are explained and discussed. Three special phenological series are presented and analyzed (flowering time of summer lime trees at Liestal, 1951 to 1989, and of the cherry trees at Liestal, 1894 to 1990, and the time of appearance for leaves of chestnut trees at Geneva, 1808 to 1991). The temporal progress of the evolution of the vegetation between 1951 to 1990 in Switzerland shows that the "early", "normal" and "late" years succeed one another irregularly. For the processing of phenological data, the fact that growth and development of a plant are determined by numerous and complex environmental factors has also to be considered.
在对物候学进行简短介绍之后，对影响植被的复杂环境因素进行了解释和讨论。展示并分析了三个特殊的物候序列（1951年至1989年利斯塔尔夏季酸橙树的开花时间、1894年至1990年利斯塔尔樱桃树的开花时间以及1808年至1991年日内瓦栗树叶子出现的时间）。1951年至1990年瑞士植被演变的时间进程表明，“早”年、“正常”年和“晚”年不规则地交替出现。在处理物候数据时，还必须考虑到植物的生长和发育由众多复杂环境因素决定这一事实。
