摘要: 以湖南省会同县杉木人工林为研究对象,对杉木伐倒木区分段数n与其材积v、平均实验形数fε的相关关系进行了分析,利用回归分析法建立了伐倒木区分段数n与平均实验形数fε的相关关系最优模型为公式。通过区分段数n与平均实验形数fε的相关关系散点图,指出最佳适宜段数nc=6。检验结果表明:模型精度高,适用性强,可为确定杉木伐倒木区分求积法的最佳适宜段数提供理论依据。

关键词: 杉木人工林, 区分求积法, 平均实验形数, 精度, 最佳适宜段数

Abstract: Cunninghamia lanceolata plantation which growed in Huitong of Hunan province was taken as research object,the relations between the sectional segments n of fallen trees,the volume v and the mean experimental form factors fε were analyzed.Regression method was used to establish an optimal regression model about sectional segments n and the mean experimental form factors fε.The optimal regression model is 公式.Through the scatter diagram of the sectional segments n and the mean experimental form factors fε,the optimal feasible sectional segments ncis six.The results showed that the model′s precision was high and usability was powerful,which provides theoretical basis for finding the optimal feasible sectional segments .

Key words: cunninghamia lanceolata plantation, sectional measurement, mean experimental form factors, precision, optimal feasible sectional segments
