摘　　要：开展森林健康评价及经营活动,首先应明确什么样的森林是健康的,怎样的结构保障了功能的健康,从而通过森林结构来调控功能,实现整个林分的健康。文章在分析健康标准内涵的基础上,结合锐齿栎林实际情况,从结构指标(群落垂直结构、水平结构、树种组成结构、年龄结构、林下植物种多样性)和功能指标(幼苗更新密度、病虫害比例、火险等级、干扰强度)两个方面阐述了锐齿栎林健康分级标准,同时以秦岭火地塘林区具代表性的锐齿栎林进行检验。结果表明,该健康标准能够客观地揭示锐齿栎林之间的健康差异,具有一定的科学性、可操作性和适用性。Before carrying out forest health measures, it is necessary to know which forests are healthy, and what kind of forest structure has kept the functional health, then we can realize the forest health by adjusting the structures. Based on the analysis of the connotation of health standards, combining with the actual situa- tion of Quercus aliena var. acuterrata forest, this article initially proposed healthy Q. aliena var. forest grading standard indicators from the structure （vertical struc- ture of community level structure, species composition, structure, age structure, understory plants species diversity） and function indicators （Q. aliena var. seed- ling regeneration density, the proportion of pests and diseases, fire danger rating interference intensity）, then chose some typical Q. aliena var. forest in Huoditang of Qinglin Mountain to test the feasibility of this criteria. The result showed that the healthy assessment criteria could reveal the health difference of Q. aliena var. for- est objectively, and provided references for further health monitor, assessment and forest management.
