摘  要：
通过对火地塘林区锐齿栎林实地调查,在分析影响锐齿栎林健康主要因素的基础上,以科学性、可行性、代表性原则,按照生产力、结构、干扰和服务功能4类指标分类评价,并通过敏感性分析,最终从52个调查指标中筛选出21个代表性指标,建立了锐齿栎林健康评价指标体系,对锐齿栎林健康状况评价。结果显示:调查的30个锐齿栎林地中,40%的锐齿栎林地处于不健康状态,27%的林地处于亚健康状态,只有33%的林地处于健康状态。以权重大小得出:林地当年凋落量、生物多样性、人为干扰程度、抗火性能4个指标是影响锐齿栎林健康的重要指标。结合样地调查发现,处于不健康状态的林地主要表现为林分结构单一、抵抗力差、种群优势度下降,人为盗伐现象严重等。为改善和促进锐齿栎林向健康状态生长提供理论依据。

摘  要：
Health situations of Quercus aliena var.acuterrata forest in Huoditang were assessed.The key factors related to the forest health were analyzed.Based the scientific,feasible,and representative principles,21 indices which were classified as productivity,structure,interference,and service function indicators were selected by sensitivity analysis from 52 indicators used in the field investigation.An index system for the assessment was established,and was applied to the practical assessment.Within 30 sampling plots,only 33% were in healthy state,40% were unhealthy,and 27% plots were in sub-health.Weight analysis demonstrated that 4 indices were the key factors for the forest health: annual litter production,biodiversity,degree of human disturbance,and fire resistance.Causes which resulted in the unhealthy state of the forest were simplicity in forest structure,poor resistance to diseases,decline of population dominance,and illegal cuttings.Aiming to solve these problems,it was suggested some appropriate management measures should be taken by relative administrations to improve the status in forest health.
