摘　　要：采用带状样地法在黄冕林场中划分4个区域,通过不同模型对4个区域的黑荆树的树高与胸径进行回程分析,选出适用于不同范围的回归方程,回归方程达到极显著水平(P<0.01),估计精确度均在94%以上,所建方程可用于计算黑荆树高及其林分平均高。Four regions were divided in Huangmian Forest Farm by strip sample method. Return analysis of height and DBH of Acacia mearnsii was made in four regions by four different models. The return equa-tions which were suitable for different regions were selected. When return equations reached to extremely significant level（P〈0.01）,the estimated accuracy reached above 94%,which could be used to calculate tree height of Acacia mearnsii and average height of stands.
