地位指数表是世界各国广泛用来评定立地质量的工具数表。为推进森林立地质量评价工作,我院也编制了“浙江省杉木实生林地位指数表”。但是,该表只适用于有林地。为了科学地评价宜林地对于杉木实生林的立地质量水平,笔者在已编的地位指数表资料基础上,应用数量化力法,进一步编制了“浙江省杉木实生林地位指数数量化得分表”。它不仅可预测宜林地造林后杉木优势高的生长趋势,确定地位指数,同时定量地给出了各立地因子的单独作用,使有林地和宜林地的杉木立地质量评价标准统一起来,为适地适树提供科学依据。
The status index table is a list of tools widely used in various countries in the world to assess the site quality. In order to promote the quality evaluation of forest site, our hospital has also compiled “Zhejiang fir real forest status index table.” However, this table only applies to forest land. In order to scientifically evaluate the site quality of Cunninghamia lanceolata forest in Yilin area, based on the compiled index of status index table, the author further developed the Quantitative Scoring Table of Cunninghamia lanceolata Solid Position Index in Zhejiang Province by using quantitative method. It can not only predict the growth trend of superiority of Chinese fir plantations after afforestation, but also determine the status index. At the same time, given the individual role of each site factor quantitatively, it can unify the assessment standards of the quality of Chinese fir site with afforestation and afforestation, Suitable trees provide a scientific basis.
