摘  要:
以923株国外松为编表样木,选用5种数学模型为一元材积的候选模型,利用非线性麦夸特迭代求解法确定各模型参数、剩余标准差、相关系数等,确定最优模型为:V=0.000 130 0 d2.435 6;以103株独立的验表样木进行总相对误差和F(0,1)检验,检验结果能满足林业生产材积估算误差要求,因此该表可为林业生产实践提供参考。

摘  要:
In 923 tree pine abroad for coding table like wood,a candidate model using 5 kinds of mathematical models for unitary volume,using the nonlinear Marquardt iterative method to determine the parameters of the model,the residual standard deviation,correlation coefficient and so on,to determine the optimal model: V = 0. 000 130 0d2. 435 6; in 103 tree example wood experience independent of the total relative error and F( 0,1) test,the test results can meet the requirements offorestry production volume estimation error. This table can provide reference for the forestry production practice.
