| 摘 要： | 在福建省南平峡阳国有林场选择20地位指数级、29 a生第1代杉木人工林建立固定标准地并调查其生长量,随后采伐,设置5种不同立地管理措施进行试验并营造第2代杉木林,开展杉木人工林连栽后的生产力变化研究.研究结果表明,加倍保留采伐剩余物处理的8 a生2代杉木林生长最好,平均胸径、平均树高、平均立木蓄积生长量分别为13.01 cm、9.20 m、16.23 m3/(hm2.a),而炼山(火烧采伐剩余物)处理的生长最差,其生长量分别为11.68cm、8.61 m、11.61 m3/(hm2.a).炼山处理的8 a生杉木林立木蓄积生长量分别为不炼山(保留采伐剩余物)和加倍保留采伐剩余物处理的90.03%和71.50%,但各处理杉木生长量均无显著差异.8 a生第2代杉木林立木蓄积量与采伐前的第1代的无显著相关,但与第1代的地位指数有极显著的正相关.

| Abstract: | By setting up permanent plots with 29-year-old,first rotation Chinese fir plantation and 20-position index level,long-term change in productivity of Chinese fir plantations over successive rotations were studied in Xiayang state forest farm,Nanping,Fujian Province,After logging,we set five kinds of site management measures to test and create a 2nd generation Chinese fir,and carry out the productivity change of Chinese fir plantation.The results showed that the best growth of the 8-year-old,second rotation Chinese fir plantation were on the double slash treatment with mean DBH,height and mean annual increment of standing volume were 13.01cm,9.20m and 16.23m^3·hm^-2·a^-1,respectively.The poorest tree growth was on the harvest slash burning treatment with mean DBH,height and mean annual increment of standing volume were 11.68cm,8.61m and 11.61m^3·hm^-2·a^-1,respectively.Standing volume in the slash burning treatment was only 90.03% and 71.50%,respectively,of standing volume in the no burning（slash retention） and double slash treatment at 8 years of age,but there was no significant difference in tree growth among the treatments.There were no significant correlations between standing volume of the Chinese fir plantations of 8-year-old,second rotation and the first rotation standing volume before felling.But there were significant correlations between standing volume of the 8-year-old,second rotation and the first rotation site index. |
