摘　　要：从福建省各台湾桂竹丰产林中设置高产林标准地１１８块，详细调查各度竹株数、胸径和竹高，建立竹林产量模型：Ｙ＝－６０９．６４３＋４．０４６Ｎ＋８７．４１５Ｄ＋０．１１３Ｘ１＋０．１３８Ｘ２＋０．１６２Ｘ３，Ｒ＝０．９９９，结合生产，提出２组约束条件．应用该模型研究台湾桂竹林最优化年龄结构，以获得不同竹林胸径、立竹量、立地条件、经营水平下最适宜年龄结构．Based on the data collected from 118 highyield Phyllostachys makinoi plots across Fujian Province, a model for predicting total yield (Y) was developed with total bamboo stems (N), average diameter(D), and bamboo shoots flushed in different years as independent variables: Y=-609643+4046+87415D+0113X1+0138X2+0162X3 Corresponding to practical production, two groups of controlled conditions were provided The model can be used to simulate optimum age structure combining such parameters as diameter, bamboo yield, site conditions, and management practices
