Abstract

Indicator values are becoming an increasingly popular tool in basic and applied botanical research: more than 55 original phytoindication systems, including about 200 optimal and range scales for various environmental factors, are known. This paper describes seven methods for calculating the phytoindication optimum of a taxonomical list: averaging with weighting by indicators of the taxon’s participation (cover, frequency, and activity) and the degree of ecological tolerance amplitude breadth. Optimum and interval indices of ecological consensus are proposed for a quantitative assessment of the level of ecological homogeneity of plant communities and floras. The distinguishing ability of the described methods of environmental calculation and consensus indices were critically compared and assessed in the environmental analysis module of the IBIS 7.2 botanical information system using data from Bashkiria and the Southern Urals at the level of phytocoenoses assigned to four communities and their coenofloras. The possible fields of further use of the results in phytocoenology and floristics are described.

在生物多样性分析中使用指标值的方法学方面

摘要

指标值正在成为基础和应用植物研究中越来越流行的工具：已知超过55种原始植物指示系统，其中包括约200种针对各种环境因素的最佳和范围尺度。本文介绍了用于计算分类列表最佳植物适应症的七种方法：使用分类单元参与度（覆盖度，频率和活动度）和生态耐受性幅度广度的指标加权平均。提出了生态共识的最佳指标和区间指标，以定量评估植物群落和植物区系的生态均匀性。在IBIS 7的环境分析模块中，对上述环境计算方法和共识指标的区分能力进行了严格的比较和评估。2植物信息系统，使用来自Bashkiria和Southern Urals的数据，并分配给四个社区及其共生植物，进行了植物亲和性分析。描述了在植物美容学和植物学中进一步使用结果的可能领域。
