摘　　要：选择1年生刺槐为造林树种,通过对造林地3～6月土壤平均含水率与当年刺槐造林成活率的回归分析,建立了二者间的线性回归方程,该方程相关系数R=0.988。同时应用该方程建立了刺槐造林成活率平均值(Y-)的预测模型,模型验证结果表明,该模型具有较强的预测能力,预测准确性较高,可应用于林业生产实践,为春季刺槐造林提供参考依据。In this experiment one-year Robinia pseudoacaci was selected as afforesting tree.Through regression analysis among mean soil moistures from March to June and one-year Robinia pseudoacacia afforesting survival rate,linear regression equation was established and the related coefficient was up to 0.988 .The equation was used for establishment of predictive model on mean afforesting survival rate of Robinia pseudoacacia ().After being verified the model was considered to have strong predictive ability and very accurate in prediction.It could be applied to forestry production so as to provide some reference for afforesting with Robinia pseudoacaci in spring.
