摘要
在对森林生态系统健康评价方法广泛研究的基础上,建立了森林生态系统健康评价的模糊层次分析模型。利用32块样地数据,运用标准差法确定评价指标的权重,采用模糊数学方法对宝天曼自然保护区森林生态系统的健康进行综合评价。结果表明,宝天曼自然保护区森林生态系统健康整体处于次健康状态,海拔是影响森林生态系统健康的主要因子。
The fuzzy analytical hierarchy model for the assessment of forest ecosystem health was established based on a widespread investigation of different methods.The model was appliced in the comprehensive evaluation on the health of ecosystem in Baotianman Nature Reserve by using the data collected from 32 sampling plots.The results showed the forest ecosystem in the reserve was inferiorly healthy,and altitude was the main factor that influenced the forest ecosystem health.
