摘要
通过对三明、龙岩、南平 3个地区的 1 31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2 1 0 0～ 2 70 0株 /hm2 ,竹林产量可达 2 3 .1～ 32 .7t/hm2 。
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/hm^2,the yield of bamboo forest will amount to 23.1～32.7t/hm^2.
