摘要:

通过对三明、龙岩、南平3个地区的131个笋竹两用林样地中株数与产量关系的研究,进行卡方检验、剩余分析、log-线性模型拟合。结果表明:3地区笋竹两用林理想的立竹量为2100~2700株/hm2,竹林产量可达23.1~32.7t/hm2

关键词: 毛竹, 产量, 密度结构, log-线性模型拟合

Abstract:

The relationship between culm numbers and yield of forest use for both bamboo shoot and timber use grown in 131 plots in three regions of Sanming, Longyan, and Nanping in Fujian Province, have been investigated and analyzed in this paper. After testing and log-linear simulating, the results showed that the amount of standing bamboo to be suitable for these areas is 2100~2700 culm/hm2, the yield of bamboo forest will amount to 23.1~32.7t/hm2.
