| 摘 要： | 试验研究了5个不同坡位对7年生杉木树高、胸径和单株材积3个性状的影响,结果表明:坡位对杉木3个生长性状存在真实影响;坡位对材积性状影响最大,对胸径性状影响次之,对树高性状影响最小;中下坡和下坡位的生长最好,显著优于其它3个坡位,上坡位的生长最差;中下坡和下坡位的保存率也最高,上坡位的保存率最低。

Influence of Position of Slope on the Early Growth of Chinese Fir |

| Abstract: | Influence of 5 different positions of slope on the height,DBH and volume of wood of the 7 years Cunninghamia lanceolata(Lamb.)Hook were studied. The results showed that:the effect of the posi?tions of slope was true;it touched the volume of wood most,the DBH second,and influenced the height lowest;the growth of Cunninghamia lanceolata(Lamb.)Hook on downhill was the best,on the upslope was the worst;the preservation rate on the downhill was the highest,on the upslope was the lowest. |
