最近发现的顺昌县高阳乡虎头山杉木丰产林,是一片与闻名国内外的南平溪后安曹下杉木丰产林相媲美的高产林分。该林分所处的地理位置及气候、土壤、植被、地形等都是杉木最适区的代表。林分单位蓄积量之高为国内外罕见,其中有许多优良种质资源,是选种、育种的好材料,是研究杉木立地类型和群落演替、探讨杉木丰产原因、林分结构、生长规律等的好场所。
The recently discovered high-yield Hutou fir plantation in Gaoyang Township, Shunchang County is a high-yield stand commensurate with the well-known high-yielding forest of the Ancao-Caoshang fir plantation at home and abroad. The geographical location and climate of the forest, soil, vegetation, topography, etc. are the most suitable area for the representation of Chinese fir. The high stock volume of forest stand is rare at home and abroad, among which there are many excellent germplasm resources, which is a good material for seed selection and breeding. The purpose is to study the site types and community succession of Chinese fir, and to explore the reasons for the high yield of Chinese fir, the stand structure and the growth pattern A good place to wait.
