青钩栲(Castanopsis kawakamii Hayata)是福建中亚热带区域性代表种。在我国除三明市莘口格氏栲天然林保护区有成片的青钩栲优势种群以外,其区域性分布仅呈零星少量。为了繁衍珍贵树种资源,推广多树种造林,莘口教学林场自60年代以来,人工成片驯化栽培珍贵树种达45个,计400ha之多。其中青钩栲人工林23年生蓄积量高达163m~3/ha,最大单株材积为0.922m~3(胸径42cm,树高18m)。是一个很成功的造林树种。研究青钩栲人工林生态系统的生产力,可对制定合理的营林技术措施提供一定的依据。
Castanopsis kawakamii Hayata is a representative of the subtropical region of Fujian. In addition to Sanming City, the population of Schistosoma japonicum natural forest protected areas have a film of green hook 栲 dominant population, its regional distribution was only sporadic small amount. In order to breed precious tree resources and promote afforestation of many species, since the 1960s, there have been 45 domestication and cultivation of precious tree species in the Xinkou Teaching Forest Farm, counting as much as 400ha. Among them, the 23-year-old plantation of A. macrophylla reached 163m ~ 3 / ha, and the largest single plant volume was 0.922m ~ 3 (diameter at breast height 42cm and height 18m). Is a very successful afforestation species. Studying the productivity of the Hook’s plantation ecosystem can provide a basis for establishing reasonable technical measures for forest management.
