| 摘 要： | 应用非线性科学中的分形几何理论，以三峡库区一移民安置示范区次生柏木林为对象，研究该群落中物种在中、小尺度上水平分布格局的分形特征，主要应用计盒维数计算群落中一些重要物种分布格局的分维值，如柏木为１ ．５８８ ，地枇杷为１ ．６１７ ，莎草为１ ．６２７ ．得到的结果与用经典群落分析方法所得结果相符，表明分维计算在本研究中是一种有效的手段；对一些物种分布分维值的进一步分析还能说明人类活动对物种分布格局或空间占有程度的影响

| Abstract: | Based on the fractal geometrical theories in nonlinear science, the fractal characteristics of distribution patterns of some major plant species in the secondary Cupressus funebris forest in the Three Gorges region were studied at middle and small scales. The box dimensions of distribution patterns of some important species were calculated. For example, the dimensions of Cupressus funebris, Ficus tikoua , and Cyperus spp. were 1.588, 1.617 and 1.627, respectively. The results tallied with those coming from classic analysis, which showed that fractal dimension is a valuable measure in this research. Further analysis of the dimensions could also illustrate the influence of human activities on species distribution patterns. |
