| 摘 要： | 利用辽河源自然保护区森林资源二类清查数据,在ArcGIS软件和CANOCO for Windows 4.5软件的支持下,采用网格样方的采样方法运用典范对应分析(CCA)法,对冀北辽河源自然保护区的森林景观要素空间分布与环境因子的关系进行了分析研究。结果表明:(1)森林景观总体表现为人工林分布在低海拔地区,天然林分布在高海拔地区,与CCA排序图上的分布一致。Monte Carlo检验结果表明海拔、坡度是影响森林景观格局分异的主要环境因子。(2)在保护区内,坡向、郁闭度和土壤厚度对森林景观类型的空间分布的影响力极为有限,海拔是控制景观要素空间分布格局的主要因素,其次是坡度,二者间接控制水、热条件,影响林分树种的分布,进而影响森林景观格局。

| Abstract: | Based on the data from the second class investigation of forest resources in the Liaoheyuan River Natural Reserve, grid quadrats sampling and CCA(canonical correspondence analysis) were used to analyze the relationship between the spatial distribution of forest landscapes in the Liaohe yuan River Natural Reserve and its environmental factors. (1) Overall performance of the forest landscapes is that the plantations are located in low-lying areas and natural forests, in high altitudes, which is the same as the distribution of the CCA ordination diagram. Monte Carlo test results show that elevation and slope are the main environmental factors affecting the differentiation of forest landscape patterns. (2) In the Natural Reserve, aspect, canopy density and soil thickness have very limited influence on the spatial distribution of forest landscape elements, and elevation is found to be the main factor to control the spatial distribution of forest landscape elements, followed by slope. Both indirectly control water, hot conditions affecting the distribution of stand species, thereby affecting the forest landscape pattern. |
