摘　　要：采用相关分析法和专家咨询法构建林分级森林健康评价指标体系,包括生产力指标、稳定性指标和生态功能指标3个方面9个指标10个亚指标,提出了利用树种组成系数计算混交度的新方法,使用层次分析法分林种赋予准则层指标权重值,利用模糊评价法对长白山金沟岭林场进行了分林种的林分级森林健康评价。结果表明,金沟岭林场用材林总体处于亚健康状态,占用材林总面积的56.4%。防护林总体处于健康状态,占防护林总面积的66.3%。因此,需加强用材林林分抚育,从而使其达到合理的林分结构并使其经济效益最大化。Based on correlation analysis and Delphi method, this paper established forest health assessment indication system for different forest classification including 3 aspects such as productivity, stability and ecological function, 9 indexes and 10 sub-indexes, and put up a new method using tree species composition coefficient to calculate mingling degree. Authors assigned different weight value to rule hierarchy indications by analytic hierarchy process, and assessed the forest health of Jingoul- ing forest farm under different forest categories by Fuzzy evaluation method. The result indicated that timber forests in sub-health condition were account for 56.4% of total timber forests area, and the timber forests were in sub-health on the whole ; meanwhile, protection forests in health condition were account for 66. 3% of total protection forests area, and proportion forests were in health on the whole. Appro- priate tending measures should be taken to improve the forest structure of timber forest, so as to gain the optimum economic effect.
