| 摘 要： | 通过分析53块样地的调查材料,系统地论述了杉木人工林林下植被与林分及立地的关系,表明杉木人工林林下植被具有较强的指示作用,林下植被类型和指示种均可作为杉木人工林立地分类及评价的依据之一。但林下植被的指示性具有一定的局限性,只有当林下植被发育到一定阶段才有较好的指示能力,而且其外延性较差,林下植被指示作用的调查结果不能无限外推。

| Abstract: | The relations between understory in Chinese fir plantation, forest stand and site are expounded systematically by anatyzing data inves tagated from 53 sample plots. The results show that the understory in Chinese fir plantation has a great indication, which can be used as one of bases for site classification and evaluation of Chinese fir plantions. However, this indication value is limited unless the understories grow and develop to a certain stage, and results from this indication investigation can not be exaggerated. |
