摘　　要：为开展杉木人工林连栽后长期生产力变化研究,笔者于1995年在福建省永春县达埔镇溪源村湖尾寮山选择1片28年生第1代杉木人工林,建立固定标准地,调查其生长量,当年年底采伐,之后在采伐迹地建立试验区,设置5种不同立地管理措施进行试验。第2年营造2代杉木林,连续18 a对其生产力变化进行调查研究。研究结果表明:D处理(收取树干,清除地被并均匀填放)杉木林生长最好,接下来依次为B处理(收取全树)、C处理(收取树干)和A处理(收取地上所有有机物),E处理(炼山)杉木林生长最差。但是它们的生长指标差异没有达到显著水平。For the development of Chinese fir plantations after long-term productivity change research, in 1995 the author chose 28 years old first generation Chinese fir plantations in Xiyuan Village Huweiliao mountain of Dapu Town of Yongchun County, Fujian province, fixed standard was established, its growth was investigated, the end of the year after cutting, the test area in slash was established with 5 different site management measures. The 2 generation Chinese fir plantation was created at the second year, and the productivity change was investigated and researched for 18 consecutive years. The results showed that： （charge trunk, clear and uniform filled） fir forest with treatment D grew best, followed by treatment B （eharge full tree）, treatment C （charge trunk） and treatment A （charge to all organic matter）, fir forest with treatment E （site burning） grew worst. But the difference of growth index did not reach significant level.
