| 摘 要： | 根据北京山区森林资源调查二类数据,在ArcGIS的支持下,采用网格样方的采样方法,进行典范对应分析(CCA),对北京山区的森林景观格局与环境因子关系进行了分析研究。结果表明,在北京山区,坡向、坡位和土壤厚度与森林景观类型的空间分布相关性较低,森林景观类型的空间格局更多地受到海拔和坡度的影响,海拔是控制森林景观类型空间分布的主要因素,其次是坡度;森林景观在总体上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,这与景观类型在CCA排序图上的分布一致。

| Abstract: | According to the survey data of forest resources in Beijing mountainous areas by CCA analysis,the relationships between distribution of forest landscape patterns and environment factors were analyzed with the help of ArcGIS.Results showed that in Beijing mountainous areas,exposure,position,and soil thickness were not the dominant factors controlling landscape pattern.The first impact factor of the landscape distribution pattern was elevation and the second was slope.Distribution of plantation was in low altitude,while the distribution of natural forest was in high altitude.This was the same as the distribution of the landscape type in the CCA diagram. |
