本文对不同自然地带杉木林的生物生产力进行了比较,结果表明:中带(相当于中亚热带)生产力最高,其后依次为南带(相当于南亚热带)和北带(相当于北亚热带)。
In this paper, the biological productivity of Chinese fir plantations in different natural regions was compared. The results showed that the middle-high belt (equivalent to the middle subtropical zone) had the highest productivity, followed by the southern zone (equivalent to the south subtropical zone) and the northern zone (equivalent to the northern subtropical zone).
