摘　　要：[目的]森林健康评价是进行森林管理的依据,开展森林健康评价能够为实现森林可持续经营目标提供一定理论基础。[方法]以太行山南麓广泛分布的侧柏人工林、栓皮栎人工林和刺槐人工林为研究对象,综合使用主成分分析法、聚类分析法和判别分析法3种多元统计分析方法,选择林分生产力、立地条件、群落结构、稳定性与可持续能力4个一级指标和21个二级指标构成森林健康评价体系,对其森林健康状态进行评价。[结果]树高、胸径、土壤全K含量、森林火险指数是影响研究区森林健康的主要因子,其主成分因子载荷均大于0.6;在所调查的17块样地中,8个样地森林健康等级为“健康”或“亚健康”(占比和为47.0%),侧柏、栓皮栎和刺槐人工林相应森林健康等级占比和分别是60.0%,33.4%和50.0%,9块样地森林等级为“中健康”或“不健康”(占比和为53.0%),侧柏、栓皮栎和刺槐人工林相应森林健康等级占比和分别是40.0%,66.7%和50.0%。[结论]整体上看,研究区侧柏和刺槐人工林林分健康状况良好,栓皮栎人工林健康状况较差。[Objective] Forest health assessment is the basis for forest management.The aims of this study are to conduct forest health assessment,and to provide a certain theoretical basis for achieving sustainable forest management goals.[Methods] This study focused on the widely distributed plantations of Platycladus orientalis,Quercus variabilis,and Robinia pseudoacacia in the southern foothills of the Taihang Mountains.Principal component analysis,cluster analysis,and discriminant analysis were used.Stand productivity,site conditions,community organizational structure,stability and sustainability were selected to evaluate the forest health status,which composed of 21 secondary indicators.[Results] Tree height,diameter at breast height,total soil K content and forest fire risk index were the main factors affecting forest health in the study area.Their principal component factor loadings were all greater than 0.6.Among the 17 surveyed plots,8 plots had a forest health level of ‘healthy' or ‘sub healthy'(accounting for 47.0% of the total),while the corresponding forest health levels of Platycladus orientalis,Quercus variabilis,and Robinia pseudoacacia plantations were 60.0%,33.4%,and 50.0%,respectively.The forest health levels of 9 plots were ‘medium healthy' or ‘unhealthy'(accounting for 53.0% of the total),and the corresponding forest health levels of Platycladus orientalis,Quercus variabilis,and Robinia pseudoacacia plantations were 40.0%,66.7%,and 50.0%,respectively.[Conclusion] Overall,the health status of Platycladus orientalis and Robinia pseudoacacia plantations in the research area is good,while the health status of Quercus variabilis plantations is poor.
