Abstract

We suggested and tested a method of quantitative estimation of heterogeneity of the ground vegetation cover using the Euclidean distance. We have demonstrated the wave nature of the vegetation, which dialectically combines discreteness (quantization) and continuum. We selected quanta of vegetation, carried out the calculation of quantized levels, the degree of heterogeneity and continuity of vegetation. The comparison of indicators of heterogeneity of forest communities held on the example of different green-moss pine forests — widespread in the taiga zone community. We selected different types of quantization depending on size, number and contrast of plant quanta. It is revealed that the heterogeneity of the living ground cover is most strongly influenced by the following factors: ecotopic (lowering of microrelief) and coenotopic (crown of firs, relationships between herb-shrub and moss species).
