摘要/Abstract

摘要：

林木生长方程是描述树种(组)各调查因子总生长量随年龄生长变化规律的数学模型,已广泛应用于估算单木树高、材积、林分蓄积等。以森林资源二类清查数据为基础,以小班为单位,针对辽西(北)地区的油松和刺槐人工林,通过7种典型的树高生长理论方程,分别拟合其在不同立地条件下的树高生长过程。结果表明;7种方程均能较好地模拟树高的生长过程,其中又以Korf方程和Logistic方程为优,拟合效果最好;在拟合过程中,渐近参数a和形状参数b,c受立地类型的影响均较大;通过对拟合方程进行检验,方程估算值与真实值之间并无显著差异,说明拟合方程能够准确地预测树高的生长过程。在此基础上,进一步对油松和刺槐的树高生长进行研究,发现:地形和坡向对油松的生长影响较大,山洼地和侵蚀沟中油松生长最好,阴坡半阴坡又好于阳坡半阳坡;刺槐则在阳坡半阳坡生长优于阴坡半阴坡。这为辽西(北)地区立地质量的评价和人工林的合理经营提供了参考依据。

Abstract:

Tree growth equations which were models for describing each of trees growth factors changing with ages have been used widely for evaluating tree height,volume,and so on. This study selected 7 typical tree growth equations to simulate tree growth process under different forestland sites for Pinus tabilaeformis and Robinia pseudoacacia plantations,respectively,which were based on forest inventory data and sub-compartments. Results showed that all 7 equations could simulate tree growth process,in which Korf and Logistic equations were better than others. Parameters a,b and c were effected significantly by forestland site. In addition,these equations were tested and could be used for predicting tree growth accurately. Then,both trees growth of Pinus tabilaeformis and Robinia pseudoacacia were simulated and it implied that Pinus tabilaeformis grew well under schattenseite and Robinia pseudoacacia grew well in this place with no sunny slope. For the western Liaoning (north) area of site quality evaluation and plantation of reasonable management,this provides a scientific reference.

Key words: western (north) Liaoning, Pinus tabulieformis plantation, Robinia pseudoacacia plantation, tree height growth models
