本文仅据几年来在岛内所见与几个林场的调查,简略介绍海南岛杉木人工林的生长概况,并分析本地的环境气候与大陆杉木中心产区的差异,说明在热带地区的局部中山区,存在杉木适生的环境条件,杉木生长良好。从土地利用范围,本岛不是发展杉木用材林的基地,但作为多种经营,以短养长,长短结合的林场,在优先发展珍贵用材树种的同时,因地制宜栽植一点杉木,是营林部门短期内解决杉材供需矛盾,自力更生,就地取材的途径。此外,对尖峰岭的杉木间伐效果,也作某些粗略的分析。
Based on the surveys we have seen on the island and several forest farms over the past few years, this paper briefly introduces the growth profile of Chinese fir plantation in Hainan Island and analyzes the differences between the local environmental climatic conditions and the producing areas of the Chinese fir center. It shows that the local Zhongshan District, there are suitable living conditions of Chinese fir, fir grow well. From the scope of land use, the island is not a base for the development of fir timber forests. However, as a multi-type forest farms with a short length of support and a short length of development, while giving priority to the development of precious timber species, Sugarcane contradiction between supply and demand, self-reliance, on-site access to resources. In addition, the Jianfengling fir thinning effect, but also for some rough analysis.
