摘要:

在闽西北各毛竹丰产林区中设置高产林标准地738块,详细调查各度竹株数、胸径和竹高以及环境因子,建立竹林产量模型:模型的复相关系数R=0.98 结合生产,提出3组约束条件。应用该模型研究毛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。

关键词: 笋竹两用林, 年龄结构, 线性规划

Abstract:

In this paper, 738 plots of high-yield bamboo stand were collected from planting area of bamboo in northwest of Fujian, through which elements of stand and environment were measured. Based on the bamboo stem yield and the shoot yield of stand, which are considered as the dependent variables, yield model was established as follows: R=0.98 Eight restricted conditions were suggested in combination with the need of production, the model can be used to optimize age structure of bamboo stand of different quality, density, and under different site condition and level of management, by which the yields of both shoot and timber can be increased obviously.

Key words: Shoot and timber use stand, Age structure, Linear programme.
