摘  要:
为了解桂西北秃杉人工林的生长特性,以广西南丹县山口林场20年秃杉人工林为研究对象,采用解析木法测定其生长规律。结果表明,秃杉在桂西北具有较强的生长适应性,20年平均胸径、树高和蓄积量分别达到19.0 cm、17.3 m、0.235 2 m3;秃杉造林初期生长较慢,其树高和胸径平均生长量均在10年生时达到峰值,此后开始下降但仍然保持较高的年生长量。其材积生长在12年生时进入速生期,至20年生时,仍然保持较快的增长速度。

摘  要:
To understand the growth regularity of the Taiwania flousiana plantation in Northwest Guangxi,the 20-year-old Taiwania flousiana plantation in Nandan Shankou Forestry Farm of Guangxi was studied by analytical tree method. The results showed that the growth of T. flousiana trees had a strong adaptability in Northwest Guangxi.Its average diameter at breast height( DBH),height and volume of stand came to 19. 0 cm,17. 3 m and 0. 235 2m3 respectively. At the initial planting stage the growth of T. flousiana trees were slow,but their average DBH growth and height growth would achieve the peak at about 10 year. After 10 years their average DBH growth and height growth still maintained a higher growth tendency. The fast growing period of volume began the twelfth year,and kept this period to the twentieth year.
