For vegetation characteristics, six statistically significant principal components were identified. The principal component analysis of the edaphic parameters revealed four statistically significant principal components. Alpha diversity, or the number of species on average at each sample point is 4.3. In the soil of the studied polygon, 38 species of soil invertebrates were identified, which characterizes the gamma diversity. The study site comprises 1.0 ha of deciduous woodland bordered by an area of herbaceous cover within the ravine. The research polygon was laid in the forest within the Orlova ravine (48✣1’13 “N, 34✤8”15 “E). The research was conducted in the ‘Dnipro-Orils’kiy’ Nature Reserve (Ukraine). The multinomial diversity model (MDM) is a method for relating the Shannon diversity to ecological factors. The article presents the results of evaluation of the role of edaphic and vegetation factors on beta diversity of soil macrofauna by means of the MDM-approach.
