影响无量山自然保护区及其周边森林分布的主要空间因子分析

Analysis of Main Spatial Factors of Impacting Forest Distribution in Wuliangshan National Nature Reserve and Its Adjacent Area

利用层次分析法(Analytic Hierarchy Process),对影响云南无量山国家级自然保护区及其周边地区森林分布的空间分异因子进行了分析。结果表明:土壤中、坡位中、土壤厚、坡位上、斜陡坡、半阳坡和半阴坡是影响无量山自然保护区及其周边地区森林分布的主要空间因子。此结果与无量山自然保护区及其周边地区森林沿空间因子的分布情况相一致,说明主要空间因子的确定是合理的。

Using analytic hierarchy process, the main spatial elements of impacting forest distribution in Wuliangshan national nature reserve and its adjacent area in Yunnan Province were analyzed. The results showed that medium soil, the slope position center, thick soil, the slope position top, the steep slope, the half sunning slope and the half shading slope are the main spatial elements. The results were accordant with the distribution of spatial elements in Wuliangshan national nature reserve and its adjacent area, which indicated that the determination of main spatial elements was reasonable.
