| 摘 要： | 为了科学引导山核桃的扩大栽植,采用样地法和固定样株法,就海拔高度对山核桃产量、胸径及树高的影响情况,对安徽省宁国市现有大量的山核桃壮龄林分进行了调查和分析,结果表明:当海拔高度低于550 m时,山核桃产量随着海拔的升高而增加;当海拔高度在550 m以上时,其产量与海拔高度呈负相关关系;海拔与其胸径呈正相关关系,而与其树高则呈负相关关系。

| Abstract: | In order to scientifically guide extension and planting of Carya cathayens,effects of altitude on yield,diameter at breast height,and height were analyzed,by investigating mature C.cathayens forest in Ningguo City,Anhui Province,using plot method and fixing sample plant method.The results showed that yield was increased with a rise in altitude when altitude was below 550 m,but it was negatively correlated with altitude when altitude was above 550 m.Altitude was positively correlated with diameter at breast height,but negatively correlated with height. |

| Keywords: | Carya cathayens altitude yield diameter at breast height height |
