摘　　要：对福建省南平峡阳国有林场29年生1代杉木人工林采伐迹地,采取5种不同立地管理措施营造的第2代杉木人工林7年生时的生长量进行调查分析,结果表明,BL3(收获树干和树皮,加倍采伐剩余物)处理对7年生2代杉木林的生长最为有利,其次为BL2(收获树干和树皮,不炼山)处理、BL1(全树收获)处理和BL0(收获地上所有有机质)处理,而SB(收获树干和树皮,炼山)处理杉木生长最差。炼山处理的7年生杉木蓄积量仅为不炼山处理的85.73%,但不同试验处理之间杉木生长量的差异均未达到显著水平(P<0.05)。The growth of 7-year-old second-generation Chinese fir（Cunninghamia lanceolata） plantations planted with five different site management treatments after harvesting a 29-year-old first-generation plantation in Xiayang State Forest Farm,Nanping,Fujian Province was studied.The results showed that the best effects on growth of the 7-year-old,second rotation Chinese fir plantation were from BL3（stem and bark harvest,double slash） treatment,followed by BL2（stem and bark harvest,no burning of residues）,BL1（whole tree harvest） and BL0（complete removal of organic matter residues） treatment.The poorest effect on tree growth was from SB（stem and bark harvest,residue burning） treatment.Standing volume with SB treatment was only 85.73% of standing volume with BL2 treatment at 7 years of age,but there was no significant difference（P〈0.05） in tree growth with different treatments.
