摘　　要：本文对江西省部分地区毛竹的形率与形数、实积系数与形积系数及它们分别与胸径、竹高之间的关系,毛竹胸径与全高、枝下高、胸高处竹壁厚度之间关系及毛竹林分径阶结构进行了研究.在此基础上,编制了毛竹竹干材积、竹壁材积、全重、用材部分重和标准根等计量数表,并对数表的编制精度及适用性进行了检验.Based on the data of culm collected from 3 districts located in Jiangxiprovince,the relationship between the culm form quotient,the culm formfactor,the coefficient of culm solid-volume,the coefficient of culm form-volumeand the culm DBH,the culm length,the relationship between the culm DBHand the culm length,the under branch length,the wall thickness of culm atthe height of breast have been dealt with.Measuring tables of culm volume,culm wall volume,total fresh weight of culm,merchantable fresh weight andstandard measurement have been worked out.Meanwhile,the tests in the accuracyand applicability of these tables have been given.
