The results of studying of a spatial variation of ecomorphic structures of soil mesofauna of artificial forest-park planting by methods OMI- and the RLQ-analysis are presented. First two axes of the OMI-analysis have been found to describe 95,23% of inertia that is quite enough, for the description of differentiation of mesofauna ecological niches on investigated range in space of the first two axes. The significant marginality average value (OMI=5,15) ð=0,01 represents communities that testifies to an important role of the selected variables of environment for structurization of community of soil mesofauna. Result of the RLQ-analysis and the subsequent cluster procedures have been revealed three key functional groups of mesopedobionts and the role of edafic factors in their spatial variation have been established.
