摘　　要：应用全球定位系统(GPS)完成对桉树资源的野外数据调查,采用多种林木直径结构模型对不同地区、不同坡位人工林桉树胸径的分布状况进行拟合分析。结果表明,威布尔分布模型较好地表达了各地区桉树的直径分布结构,拟合效果最好,并分析其直径结构特征,为科学地进行桉树人工林定向培育提供可靠的理论依据。Based on the investigated data using GPS, different diameter models of trees were used to fit the distribution of eucalyptus plantations in different regions and different slopes. The results showed that Weibull distribution model was the best one among the several models. And it analyzed the structure characteristics of diameter as well. It provided a reliable theoretical basis for carrying out scientific oriented cultivation of eucalyptus plantations.
