【摘要】 对秃杉杉木檫树混交林、秃杉杉木混交林以及秃杉、杉木纯林的生物量及其空间结构进行研究 ,结果表明 :秃杉混交林比秃杉纯林具有更高的生产力 ,混交林中又以秃杉杉木檫树混交林的生产力最高 ,林分总蓄积量达 87.59m3·hm-2 ,总生物量达 77.58t·hm-2 ,分别比秃杉纯林高 43 .3 %和 3 2 .4% .混交林林分具有一定成层性 ,林分结构比秃杉纯林更有利于生物量的积累 ,而且秃杉的生长比杉木更快、更好更多还原

【Abstract】 A comparative study was made on the productivity and stand structure among different kinds of mixed forests of T flousiana and pure forests of T flousiana and C lanceolata The results showed that the mixed forests had higher productivity than pure forests; the mixed forests of T flousiana, C lanceolata and S tzumu had a maximal productivity; that the stand stock and biomass of the mixed forest (T flousiana, C lanceolata and S tzumu) increased by 43 3% and 32 4% respectively as compared with the pure stand of T flousiana, which was 87 59 m\+3·hm\+\{-2\} and 77 58 t·hm\+\{-2\}; that the mixed forests were more rational than pure forest, whose stand structure would enable the mixed forest to yield more out turn and biomass and in which the growth of T flousiana is faster than that of C lanceolata更多还原
