针对哈溪保护站森林群落脆弱性特点,采用主成分分析方法确定各评价因子权重,建立了基于主成分的脆弱性评价综合模型。借鉴波士顿矩阵评价方法对森林群落因子脆弱性进行评价,采用上述模型对保护区哈溪各森林群落脆弱性进行了评价,结果表明:哈溪各种森林群落脆弱度由小到大排序为:云杉+红桦、云杉、云杉+山杨、红桦、云杉+圆柏、红桦+云杉、圆柏+云杉、山杨、红桦+圆柏、圆柏。
According to the characteristics of forest community vulnerability in Haxi Protection Station, the weight of each evaluation factor is determined by principal component analysis, and the comprehensive model of vulnerability assessment based on principal component is established. Using the method of Boston Matrix Evaluation to evaluate the vulnerability of forest community factors, the above model was used to evaluate the vulnerability of Haxi forest communities in the protected areas. The results showed that the vulnerability of various forest communities in Haxi ranked as follows: Fir + red birch, spruce, spruce + aspen, red birch, spruce + Sabina, red birch + spruce, Sabina + spruce, aspen, birch + Sabina, juniper.
