| 摘 要： | 通过对桉树人工林106块标准地和242株样木进行调查,在前人工作的基础上提出一元材积的通用模型V=a+bDc+eDf和V=aDb(c+eD)fDg,模拟效果优于一般的方程,经检验适用,可用于林业生产实践。利用该方程编制的桉树一元材积表,误差小,可在森林调查中应用,能满足林业生产上的精度要求。

| Abstract: | Through investigating 106 standard plots and 242 sample trees in the plantations of Eucalyptus,several standing volume equations were used to fit and compare,then a standing volume table of Eucalyptus was worked out.Based on the previous works,two general models for one single volume have been put forward as follow:V=a bD~c eD~f and V=aD~b(c eD)~fD~g.The results were better than the normal equations in the analogue practice.The two new equations were proved to be applicable,and could be applied in the forest production and practice.The table basing on the equation of V=a bD~c eD~f could be applied in the forest investigation.Meanwhile its error was small.It could meet the precision demand in the forestry production. |
