摘要: 成子纯先生的《湖南马尾松经营计算图的编制》刊于《林业科学》1984年第1期,本文就文中编制标准表的方法及依据进行讨论。用作者为其经营计算图自编的标准表(全称每公顷林分断面积和蓄积量标准表)的内含形数(f1.3和fa)与过去常用的中南马尾松标准表内含形数比较;同时通过标准地实际材积进行检验,结果发现作者的标准表由于编表方法和依据欠妥,导致其测算材积比实际值及中南表均有较大的误差,并超出了允许的误薯限。

Abstract: Mr.Cheng Zichun’s paper of“A Study on the Management- Calculation Diagranl of Pinus massoniana in Hunan”was published in “Forest Science”,No.1,1984.The meth'od and base of compilinging standard table in author’S paper are mainly discus sed in this paper.By means of comparing the breast height form factor (f1.3)and the experimental form factar(fa) contained in the standard table (the whole name calls“the Standard Table of Basal Area and Volume of Per Hectare Stand”)which the author compiled for his Calculation-diagram with those of the Central-South Pinus massoniana Standard Table which was often used in the past,by testing with real volume of sample plots,we found that because the base of that table and the compiling method are not reasonable the author's standard table will bring about greater error than the real volume of Stand,or that of Central-South Standard Table when it is used to estimate the volume of stand,meantime,the error goes greatly beyond the permitted limit,so we think that it is not Suitable for use in practice.
