应用1988年的调查资料,对1978年编制的刺槐、杨树一元材积表及平均形数法计算林分蓄积的适用性检验结果证明:刺槐一元材积表尚可继续使用,杨树一元材积表精度较低,已不适用;平均形数法可以取得与二元材积表大体相同的精度。建议编制新的杨树一元材积表,并在林分调查中推广应用平均形数法。 According to the survey data of 1988, the applicability test of calculating the stock volume of the locusts, the poplar single-volume table and the average number-of-shape method prepared in 1978 shows that the locust table of the locust tree can still be used continuously, the accuracy of the poplar one- Lower, not applicable; average shape method can be obtained with the binary volume table roughly the same accuracy. It is suggested that a new poplar monoculture volume chart should be compiled and popularized and applied to the average forest type survey.
