| 摘 要： | 作者提出的变型Ｗｅｉｂｕｌｌ分布模型是以Ｗｅｉｂｕｌｌ分布密度函数为基础，进行适当变换形成的４参数分布模型。用该模型对海南省热带山地雨林的林分结构规律进行研究，结果表明，该模型具有灵活性强、适应性广的特点，对异龄林和同龄林皆适用，并能提高模型参数的估计精度。同时本研究改善了ｘ＾２检验模型拟合适度的稳定性，取得了较好的模拟效果。

| Abstract: | The improved Weibull distribution model with 4 parameters mentioned in this paper is based on the standard Weibull distribution. According to the research on the stand structure of the tropical mountainous rain forest of Hainan province, the more satisfied simulating results are obtained. The research shows that the model has a wide application to even-aged stands and uneven-aged stands, with a higher estimate precision. |
