摘要
根据样地调查数据,采用方差分析法、显著性分析和多重比较分析法,分析不同坡向、坡位、坡度、土壤等立地因子下的秃杉人工林树高、胸径平均生长量状况。结果表明:不同坡向、坡位、土壤厚度对秃杉人工林林分生长均有显著影响;影响秃杉人工林林分生长的最主要立地因子为坡位、坡向和土壤厚度;秃杉最适生的立地条件为坡下部、阴坡、土壤深厚。
According to sample-plot survey date,and using methods of variance analysis,significance analysis and multiple comparisons,the effects of site conditions including slope aspect,slope position,gradient,soil etc on the growth status of tree height,DBH have been analyzed. The results show that:different aspect,slope position and soil thickness have significant influence on the growth of. Taiwania flousiana plantation. The optimum site conditions for Taiwania flousiana plantation are considered as downhill,shady slope,deep soil.
