摘要: 采用树干解析法对剑阁县藏柏人工林生长规律进行了研究。结果表明:27 a藏柏树高、胸径与材积生长量分别达到了18.13 m、25.8 cm、0.407 55 m³;此时年平均生长量分别为0.67 m、0.96 cm、0.015 09 m³。树高的快速生长期为12 a~21 a,期间连年生长量为0.71 m·a^-1~0.93m·a^-1,胸径的快速生长期为9a~15a和21a~24a,期间连年生长量分别为1.17cm~1.22cm、1.09cm~1.21cm,材积年平均生长量与连年生长量曲线都随年龄增加而增加,到27 a时分别为0.03428m³·a^-1、0.01509m³·a^-1,而且并没有相交,说明材积生长还没达到数量上的成熟。采用逻辑斯蒂(logistic)模型进行拟合得树高、胸径和材积相关系高达0.997、0.992和0.999,说明可用该模型对藏柏人工林的生产实践进行指导。

Abstract: The research was conducted on the growth characteristics of Cupressus torulosa plantations in Jiange County in Sichuan province by using the stem analysis method.The results showed that the height,DBH and volume of 27-year-old Cupressus torulosa were trees 18.13 m,25.8 cm,0.407 55 m³,respectively.Their mean annual increments were 0.67 m,0.96 cm and 0.015 09 m³.The fast growing period of tree height was in 12 years old to 21 years old and the current annual increment was 0.73 m·a^-1~0.93 m·a^-1.While the DBH had two fast growth periods,which were from 9 years old to 15 years old and from 21 years old to the 24 years old,respectively.The current annual increment was 1.17 cm·a^-1~1.22 cm·a^-1 and 1.09 cm·a^-1~1.21 cm·a^-1.Average increment curve and current annual increment curve of volume increased with the age.After 27 years,average increment and current annual increment of volume reached 0.015 09 m³·a^-1 and 0.034 28 m³·a^-1,and that didn't intersect.So Cupressus torulosa trees had not reached the quantitative maturity of volume.The logistic equation was good to fit the growth regularity of height、DBH、volume of Cupressus torulosa plantations,getting the relative values were 0.997,0.992 and 0.999.So it could be used to guide the production practice of Cupressus torulosa plantations.
