林分模拟径阶株数法确定小班蓄积的试验

Using a model of diameter distribution of forest to determine the subcompartment stock

利用数学模拟方法对小班林木径阶株数分布和小班蓄积量进行了模拟试验,结果表明:模拟法与标准地实测法差异不显著,且模拟法具有实用性强、生产使用方便、能充分发挥计算机的优越性等特点,可以快速模拟出林分的直径分布,为林业调查提供了快捷有效的技术手段。

The diameter distribution of forest and subcompartmeut stock were determined by a mathematical stimulation. The results showed： there were no significant differences between the calculated and measured values. Furthermore, the model was practical and convenient, which could stimulate diameter distribution of the trees quickly, and provide an effective technology for the forest investigation.
