【摘要】 本文试用广布于福建莆田县全境的亚热带针叶林下木种群特征的分异,以种类相似性指数作样地聚合分类,划分出其植物区系成分、生活型组成、自然条件与农业生产特点等均相应地有较明显差异的全县三个样地组合,工作结果与按常规的用主要植被类型组合和生境等综合特点所作的区划基本上相吻合,这表明本文的植被分析方法对县级以下的植被分区基本上是可行的.其次分析了三个样地组合(植被段)的气侯、土壤、植被与农业生产等不同特点,并作适当的评述。更多还原

【Abstract】 The present paper cosists of three parts. The first part deals with the synthetical indexes of dividing three sectors using the similarity index,the charaters of geographical distribution and life-form of undergrowths in the pine forests. The second part deals with the character of plant c vers in three sectors. Finally, The authers sum up the features of the soil,climate and all vegetations in this county and discuss the significance of this vegetation division.更多还原
