摘要:
 提出一套具有科学性、合理性、实用性的次生林健康评价指标体系,为客观评价次生林健康状况提供参考依据。根据试验地概况及二类调查数据,采用专家咨询法对指标进行筛选,构建了金钩岭林场杨桦次生林健康评价指标体系;使用层次分析法赋予指标权重,确定指标阈值,对试验地912个小班进行森林健康评价。结果表明:不健康小班占总评面积0.76%,亚健康小班占80.49%,健康小班占18.75%,没有疾病和优质的小班。金钩岭林场杨桦次生林主要处于亚健康状态,可通过及时确定影响健康等级主导因子,加以经营和管理林分,提高林分的健康水平。
Abstract:
 A scientific,rational,and practical health assessment index system for secondary forests were established to provide a reference for the objective evaluation.The experiment was conducted in Jingouling Forest Farm,Jilin Province,China.The general health status of 912 polar-birch secondary stands in the farm was assessed.Based on data of the second type of forest resources survey,factors for the assessment were screen by the method of expert consultation,and then they were weighed by analytic hierarchy process to get threshold values.The results showed that 0.76% of total assessment areas were unhealthy,80.49% were sub-healthy,and 18.75% were healthy.No high quality or disease-free stands were found,indicating that the secondary forests in the farm were in a sub-healthy condition.To improve the health situation,dominant factors should be determined to guide the further management of the stands.
