本文根据树干解析资料,应用灰色系统理论模型,对太行山刺槐水保林的生长进行了预测分析,并建立了树高、胸径和材积总生长量,平均生长量和连年生长量的预测模型。预测分析的结果表明,GM(1,1)模型精度比较理想,而Verhulst预测模型误差较大。并根据树干解析资料,分析了刺槐水保林的速生期。 Based on the analytical data of the trunk and the gray system theory model, the prediction of the growth of the R. pseudoacacia forest in the Taihang Mountains was carried out. The prediction models of total growth, average growth and annual growth of tree height, DBH and volume were established. The results of predictive analysis show that the GM (1,1) model is more accurate and the Verhulst model has larger errors. Based on the analysis data of trunk, the quick-growing period of acacia water-conserving forest was analyzed.
