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。
There are four key aspects in the study of forest ecosystem health assessment using insects, such as selection of indicators, selection of survey time, sampling and analysis of results. This paper summarizes and discusses the related problems in this kind of research both at home and abroad. According to the literature, the criteria for selecting insect indicators are summarized. The different insect groups should be appropriate in the season of choosing survey time, and the length of investigation time should fully reflect the variation cycle of population quantity of the insect groups studied. The sampling should pay attention to canopy layer. In the analysis of the results, attention should be paid to the distinction between human interference and natural factors.
