摘　　要：利用昆虫进行森林生态系统健康评价的研究中存在指示物选取、调查时间选择、取样和结果分析四个关键环节,本文对国内外此类研究中存在的相关问题进行总结和讨论。根据文献资料总结了选取昆虫指示物的标准;不同昆虫类群在选择调查时间的季节上要适当,调查时间长度要能够完整反映所研究昆虫类群的种群数量变动周期;取样时要重视林冠层;在结果分析中,要注意区分人为干扰和自然因素的作用。Indicator selecting, investigation season anti ouratlon, specimen collection and results analy-sis are crucial parts when indicator insects are used to evaluate the forest ecosystem health. The related issues in the studies were discussed. According to the literature, the criterions of the insect indicator se- lection were summarized, and some suggestions were also brought up. The appropriate investigation sea- sons are different with different insect species, and duration should be long enough to reflect the periodi- cal fluctuation of the target insects. Canopy should be paid much attention in the field investigation. The imoacts of human activities and natural factors should be distinguished in the results analysis.
