地位指数表是评价林分立地质量的基础数表。本文为研究浙江省杉木实生林立地质量评价标准,选设标准地154块,解析木33株,就林分6株优势木平均高与林龄的相关关系,经3个方程比较,选定半对数方程配制导向曲线,并以2m级距、标准差法,导出各指数曲线,编成地位指数表。同时,以地位指数为基础,提出浙江省杉木立地质量评价标准,并探讨了林分平均高与优势高,以及优势木不同选取方法和不同株数之间平均高的换算方法,为简化野外测定和应用摸索新途径。
Status index table is to assess the quality of forest stand base number table. In order to study the evaluation criteria for the quality of Chinese fir plantation in Zhejiang Province, 154 standard plots and 33 analytical trees were selected. Based on the above three relationships, Logarithmic equation preparation guide curve, and 2m-class distance, standard deviation method, the export of each index curve, compiled index table. At the same time, based on the status index, this paper puts forward the evaluation criteria for the site quality of Chinese fir in Zhejiang Province and discusses the methods of converting the average height and the superiority of the stands, as well as the average high selection method and the average number of the different superior trees. Application of new ways to explore.
