摘　　要：2020年7月,在湖北省太子山林场管理局雁门林场44 a生柏木人工林中设置临时标准样地,并选取标准木进行树干解析和测定,对柏木生长规律进行研究,结果表明:柏木胸径和树高生长快速期都出现在10~20 a,胸径和树高的连年生长量均在第20年生时达到最大值,胸径和树高的平均生长量均在第30年生时达到最大值,材积连年生长量第40年时出现最大值;在44 a期间材积平均生长量一直处于上升趋势,没有达到最大值;胸径生长率和树高生长率最大值出现在第10年,材积生长率最大值出现在第20年。Yanmen forest farm in hubei province Jingshan County set up standard samples of 44 years plantations of Cupressus funebris temporarily,and select standard wood tree for parsing and determining,to study the growth rule of Cupressus funebris in July 2020.The results showed that the rapid period of diameter at breast height,tree height growth at early stage;The annual increment of DHB and average increment growth a maximum at 10-20 years;The annual increment of tree height and average increment growth a maximum at 20 years;When 30 years volume increment reaches a maximum,and average volume increment has been characterized by steady growth trend,within 44 years volume average growth rate has been rising,have not reached the maximum;The breast height form number from the second year in a downward trend;The maximum growth rate of diameter at breast height and tree height growth rate was in 10 years,the maximum volume growth rate was in 20 years.
