摘要
以森林资源二类调查数据为评价依据,构建八达岭国家森林公园森林健康评价指标体系,运用层次分析法确定各指标的权重,并采用模糊综合评判法对森林健康等级进行评价。结果表明:从评价指标权重来看,树种组成、群落层次结构、林分蓄积量、郁闭度、腐殖质厚度等5个指标对八达岭国家森林资源质量影响较大,5个指标权重之和占总权重的80.8%;北京八达岭国家森林健康等级为中等,属于亚健康状态。亟需采取措施提高园区森林的生物多样性和群落层次结构稳定性,使森林向健康的方向发展。
Based on the forest inventory data ,the forest assessment indicator system for Badaling National Forest Park was built , the index-weight was determined with analytic hierarchy process;using fuzzy comprehensive evaluation ,the forest health ordination was evaluated, takeing three scenic spot of Badaling National Forest Park for example .The results showed that ,Badaling National Forest Park belonged to the middle level ,belongs to sub-health state,it is urgent to take effective actions of forest resources management to improve species diversity and construction of forest community ,to make the forest to develop in the healthy way .
