中文摘要：
在福建省南平峡阳国有林场进行5种不同立地管理措施对29年生第1代杉木人工林采伐后营造的6年生第2代杉木人工林生产力影响的研究。结果表明：BL3（收获树干和树皮、加倍采伐剩余物）处理的6年生2代杉木林生长最好，其次为BL1（全树收获）和SB（收获树干和树皮，炼山）处理，BL2（收获树干和树皮，不炼山）和BL0（收获地上所有有机质）处理杉木生长最差。5种处理的第2代杉木林地位指数与第1代相比，BL3和BL0处理分别上升0．56和0．27，其余3种处理则有下降。BL1、SB和BL2处理地位指数分别比1代下降0．39、045和0．63。不同处理之间的差异均未达到统计上的显著水平。
英文摘要：
The effects of five different site management treatments on productivity of 6-year-old, second rotation Chinese Fit （ Cunninghamia lanceolata） plantations planted after harvesting a 29-year-old, first rotation Chinese Fir plantation in Xiayang State Forest Farm, Nanping, Fujian Province, were studied. The results showed that the Chinese Fir stand grew the best on the double slash treatment （ BL3 ）, followed by the whole tree harvest treatment （ BL1 ） and slash burning treatment （SB）, and the poorest on the no slash burning treatment （ BL2 ） and the no slash treatment （ BL0 ）. The site index of the second rotation Chinese Fir plantations in the BL3 and BL0 treatments increased by 0.56 and 0.27, respectively, compared with the first rotation, and decreased in the rest of the 3 treatments. Compared with the first rotation, site index of the second rotation treated with BL1 , SB and BL2 treatments decreased by 0.39, 0.45 and 0.63, respectively. Differences between the treatments were not statistically significant.
