为揭示不同经营方式对闽南山地典型人工林生长和生产力的长期影响，选择成熟的杉木纯林、杉木+马尾松+木荷混交林和杉木+马尾松+火力楠混交林为研究对象，对目标树种的生长和林分生产力进行了调查研究，结果表明：与纯林相比，混交林的经营方式均提高了杉木的生长量，林分蓄积量也显著高于杉木纯林，以5杉木5马尾松林分的蓄积量最高，为156.85 m3 hm-2。

In order to reveal the long-term effects on growth & productivity of typical plantations under different management modes in Southern Fujian Province,the mature pure forest of Cunninghamia lanceolata ,the mixed forest of C.lanceolata+Pinus massoniana +Schima superba and the mixed forest of C.lanceolata+Pinus masso-niana +Michelia macclurei were selected as the research subject,the growth and productivity of the target species were investigated.Result showed that compared with the pure forest,the growth of C.lanceolata was increased by adopting management modes of mixed forest;the stocking volume of the mixed forest is also significantly higher than that of pure forest;the stock volume of five strains of C.lanceolata + five strains of Pinus massoniana is the highest,being 1 56.85 m3 hm-2 .
