摘要
通过对26a生拉氏栲与杉木人工林蓄积生长、林分生物量和林分空间格局的测定分析,进行拉氏栲和杉木人工林生产力的比较研究。结果表明:拉氏栲人工林单株材积为0·2293m3/hm2,比杉木人工林高14·76%,但其林分蓄积量小于杉木林;拉氏栲林分生物量为148·59t/hm2,是杉木人工林的1·13倍;其干、枝、叶和根的生物量均高于杉木林,拉氏栲根系十分发达,其根系分布较杉木更为合理,说明拉氏栲人工林的林分空间格局比杉木人工林更有利于林分光合产物的积累。拉氏栲生产力较高,可望在南方大面积推广。
The biomass productivities of Castanopsis lamonteii and Cunninghamia lanceolata plantation were compared based on the investigation of stand volume growth, biomass production and structure. The results indicated that the stand volume of Castanopsis lamonteii plantation was 0.229 3m^3/hm^2, 14.76% higher than that of Chinese fir plantation. The stand total biomass production of Castanopsis lamonteii plantation was 148.59 t/hm^2, 1.13 times as much as Chinese fir plantation. It could be deduced that Castanopsis lamonteii was a fast-growing specie.
