The purpose of the work is to develop the principles and methods of spatial ecology as a scientific basis for the protection of biological and landscape diversity, of the restoration of soil fertility under conditions of intensive agricultural production and land reclamation. For the first time the spatial patterns of living organisms were established on reclaimed technozems; the algorithm describing the spatial variability of point objects and testing hypotheses on the nature of causal relationships that generate it were developed; a system of ecogeographical predictors of living organisms' ecological niche at a landscape level was created; the correlation between the theory of ecological niche and the theory of neutrality is shown to explain the organization of communities; the technique of estimating of the soil mesofauna spatial variability was developed; bioindicators of quality and negative properties of agrozems were substantiated. Methodological approaches for determination and estimation of population spatial variation at a level of biogeocoenosis were scientifically grounded; the system of ecogeographic indicators was substantiated on the basis of the Earth remote sensing data as the ecological niche markers at a landscape level. The scientific basis for restoration of biotic potential allowed to achieve successful development of organic agriculture in the country. The ecologization of agro-industrial production led to an increase in the internal consumer market for organic products to EUR 33 million. An important marker of the efficiency of modern technologies to restore the biotic potential of agro-ecosystems is that in 2018 the export of organic products amounted to 104 million euros and is constantly increasing. This provided Ukraine with the 4th place among all world countries in terms of export volumes of organic agricultural products to the EU with 8.2 % of total imports. National and world analogues of such a cycle of scientific works are absent.
