| 摘 要： | 采用树干解析法,研究广西平果县海明林场23年生大叶栎人工纯林生长规律。结果表明：23年生大叶栎人工林平均胸径、树高和材积分别为19.4 cm、20.4 m、0.3261 m3。胸径、树高和材积生长速生期分别为2~8、6~11、6~23年,材积连年生长量与平均生长量曲线在23年时仍没有相交,说明23年生大叶栎人工林材积生长还未达到数量成熟龄。大叶栎胸径、树高和材积生长方程分别为D=1.713 3T-0.050 6T2＋0.000 7T2-1.942 2、H=1.925 7T-0.039 8T2-2.489 0、V=-0.010 4T-0.002 4T2-4.084 8e-0.005T2＋0.012 7。通过拟合方程推算,大叶栎材积将于第24年达到数量成熟。 |

| Abstract: | This paper studies the growth law of 23-year-old Castanopsis fissa planta- tion in Haiming forest farm （Pingguo County, Baise City, Guangxi Province） with the method of stem analysis. The results show that the average DBH, tree height and volume of the 23-year-old C. fissa plantation are 19.4 cm, 20.4 m and 0.326 1 m3 respectively. The fast growing periods of DBH, tree height and volume are the 2^nd- 8^th, 6^th-11^th, 6^th-23^nd year. Annual increment curve and average increment curve of volume haven＇t intersected in the 23 years, which means the 23-year-old C. fissais plantation has not reached the quantitative mature age. The growth equations of DBH, tree height and volume are D=1.713 3T-0.050 6T2＋0.000 7T2-1.942 2, H= 1.925 7T-0.039 8T2-2.489 0, V=-0.010 4T-0.002 4T2-4.084 8e^-0.005 T2＋0.012 7. Ac- cording to the volume regression equation of Castanopsis fissa, it will reach quanti- tative maturity in the 24~ year. |
