| 摘 要： | 以杨树人工林为研究对象，利用5种分布模型分析杨树人工林直径和树高的分布。结果表明：威布尔分布描述杨树人工林直径、树高分布效果最好；同时结合树高曲线，利用胸径威布尔分布导出树高分布，并通过卡方检验。 |

| Abstract： | In the paper, the poplar plantation was taken as the study objects, and 5 distribution models were used to fit diameter and height distribution of the poplar plantation. The results showed that Weibull distribution model was the best one to describe the diameter and height distribution of the poplar plantation. With the model of the relations between diameter and height, the Weibull diameter distribution was used to export height distribution, and the results was passed by Chi-square test. |
