摘要：【目的】通过构建栎属Quercus单木生长模型,分析栎树生长特征,为栎属植物质量精准提升、结构优化与合理经营提供依据。【方法】汇总整理栎属3个树种(槲栎Q.aliena、麻栎Q.acutissima、栓皮栎Q.variabilis)解析木各阶段生长量信息,分析栎树单木树高、材积、胸径生长特征;选取4个理论生长方程、1个经验方程及3个胸径处树皮厚度方程拟合并检验栎树单木的树高、材积、胸径与树皮厚度,优选出适应性最强、稳定性最高的模型。【结果】①各栎树单木生长过程符合一般林木生长规律:在前40~50 a树高与胸径生长速度较快,之后随着平均生长量和连年生长量的降低逐渐减小;材积各生长量始终保持随树龄的增大而增加的趋势。②栎树模型拟合结果为:树高拟合最优模型多为逻辑斯蒂(Logistic)模型,材积拟合最优模型多为坎派兹(Compertz)模型,胸径拟合最优模型多为修正威布尔(Weibull modified)模型。③气候对栎树生长影响的结果表明:气候差异导致山西省和河南省槲栎生长发生明显差异。④树皮厚度拟合最优模型为双对数模型和二元一次线性模型。【结论】树高模型对栎树生长拟合效果最佳,实际意义较强;槲栎对气候敏感性较强。图5表4参23。
[Objective]This study,with the construction of a growth model and the analysis of the growth pattern of Quercus,is aimed to provide reference for accurate quality improvement,structure optimization and rational management of Quercus.[Method]First,with the original data of trunk analysis of three species of Quercus(Q.aliena,Q.acutissima and Q.variabilis)at each period collected,an investigation was conducted of the growth pattern of tree height,volume and diameter at breast height(DBH).Then,four theoretical growth equations,one empirical growth equation and three bark thickness equations were selected for the fitting and testing of the growth process of the height,volume,DBH and bark thickness of the wood so as to find out the most suitable tree growth model.[Result](1)The single tree growth process of Quercus accorded with the generally regular pattern of forest growth,with the growth of height and DBH being faster in the first 40?50 years and then slowing down with the decrease of average growth and annual growth while the tree volume kept increasing with the increase of tree age;(2)As was shown in model fitting results,the optimal growth equation of the height was the Logistic equation,the optimal growth equation of the volume was the Compertz equation whereas the optimal growth equation of the DBH was the Weibull modified equation;(3)As for the impact of climate on Quercus growth,climate variation led to significant differences of Q.aliena growth as was shown in those growing in Shanxi Province and Henan Province respectively;(4)The optimal bark thickness fitting model was Binary linear model.[Conclusion]The tree height equation,with strong fitting effect on Quercus growth,has strong practical significance and Q.aliena is more sensitive to climate.[Ch,5 fig.4 tab.23 ref.]
