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 (f_1.3)and the experimental form factar(f_a) 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．
