| 摘 要： | 运用典范对应分析(CCA)方法分析了地形对火地塘林区主要森林景观类型分布格局的影响;同时引入每个样本的空间坐标,定量分离了地形、空间及其交互作用等因素对景观格局总体变异的影响。研究结果表明,地形、空间及其交互作用解释的植被结构变异分别为4.465%,15.659%和3.78%,总共解释了全部植被结构变异的23.906%,尚有76.094%的变异不能得到解释。

| Abstract: | The influence of terrain on the forest landscape pattern in Huoditang forest region was studied by the method of canonical correspondence analysis ordination, At the same time,the influence of topographical factors ,spatial factors and their interaction on the total variance of Landscape pattern were quantitatively partitioned. The results suggested that the contribution of the 3 asepects was 4.465%, 15. 659% and 3.78% respectively. The total variance explained were 23. 906% by the topography and 76. 094% of the variance were not interpreted yet. |
