- Аннотация: The resistance of ground ecosystems to climatic influences is largely determined by the soil cover condition, where the organogenic horizon (ground litter) plays a crucial role. The interaction between vegetative waste and micro- and meso-organisms is regulated by temperature, humidity, physicochemical parameters of the environment, which altogether form an ecological niche of such an organogenic horizon. This paper aims to analyze the formation of ground organogenic horizons in various combinations of bio-climatic factors (ecological niches) and hence identify their association with soil-phytocenotic communities – various ground ecosystems. The study used the following methods: expert assessments, mapping, geographic forecasting, mathematical methods (correlation, dispersion, regression analysis, information-statistical method for assessing the intercomponent conjugacy of phenomena and factors), taxonomic method for categorizing the ground ecological niches. The quantitative parameters of soil-climatic factors (amount of ground litter, t/ha, active temperatures above 10 °C, precipitation ratio, redox potential, mV) that affect formation and development of ground organic horizons, were assessed. Four types of ecological niches formed in various ecosystems of the Earth were identified. The findings can be useful for a comparative analysis of the functioning of various ground ecosystems, the choice of methods for their rehabilitation and forecasting of their evolution in changing climate.
