| 摘 要： | 通过对猴欢喜和杉木人工林生长及生物量测定,进行猴欢喜和杉木人工林生物生产力的比较研究,结果表明:在相同立地条件下,猴欢喜人工林的胸径和树高生长均低于杉木林,28年生猴欢喜人工林蓄积量为262.93 m3.hm-2,比杉木林低33.25%;但猴欢喜林分乔木层生物量是杉木林的1.39倍,乔木层生物量在各器官的分配比例均表现为:干>根>枝>叶,但杉木林干所占比例高于猴欢喜,林分生物量在各层次的分配比例表现为:乔木层>灌木层>草本层。猴欢喜林分年均净生产量是杉木林的1.31倍,说明猴欢喜人工林叶净同化率较高。

| Abstract: | Based on the investigation of stand growth and biomass,the biomass productivities of Sloanea sinensis plantation and Cunninghamia lanceolata plantation were compared.The results showed as follows: the stand volume of S.sinensis plantation was(262.93) m~3·hm~(-2),decreased by 33.25 percent compared with that of Chinese fir plantation.The total stand biomass of S.sinensis plantation was 1.39 times as much as that of Chinese fir plantation.The ratios of different organ to total biomass were in sequence of stem>root>branch>leaf.The annual net biomass productivity of S.sinensis plantation was higher than that of C.lanceolata plantation. |
