摘　　要：在不同岩性土体上进行了杉木栽植的研究。 10年的研究结果表明 ,不同岩性所发育的土壤对杉木的高、径生长的影响是很显著的。其中以玄武岩与石英砂岩发育的土体上的杉木生长最好 ,依次为长石石英砂岩与变余砂岩 ,而以煤系砂页岩和第四纪红色粘土上的杉木生长最差。分别对不同岩性土体上杉木的年龄与高和径之间进行了统计分析 ,结果表明 :同一岩性土体上杉木年龄与高和径间成正相关 ,且相关关系显著。China fir were planted at the soils from different rocks by the experimental ecological method. The results of 10 years showed that the effects of soils on the growth of China fir were significant. The China fir grows well at basalt and quartz sandstone, but poor at clay and sand shale. Meanwhile, the relation between the diameter and height of trees and its ages were statistically analysed, and the positive correlation was significant. The study provided the basis for the site classification of China fir in which rock must be considered.
