Landscape-ecological analysis of taxonomic diversity and structure of soil invertebrates’ community in the geosystems of the Hamar-Daban Region was carried out on the main levels: local (biogeocenotic), topological (facies) and regional. The paper considers regularities of transformation of communities’ structure in landscape-zonal range under the influence of natural conditions: phytocenotic (peculiarities of vegetation), edaphical and climatic (hydrothermal regime of the soil) and anthropogenic factors. On the models groups: Сarabidae, Staphylinidae, Elateridae, Formicidae altitudinal changes of community' structure have been traced; in all landscape-high-rise complexes (in species composition and abundance of species) was revealed forest preference. The main trend of changes in taxonomic diversity of invertebrate’s communities is a decrease in the species number in the gradient of an increase of climate aridity, and strengthening of the hypothermal character and anthropogenic pressure. Peculiarities of structures invertebrate’s communities and their changes due to the climate change and anthropogenic impacts can serve as one of diagnostic criteria of soil conditions and can be used for estimation of landscapes’ transformation and monitoring.
