Annotation:  The article is a logical continuation of the article, which presented a comprehensive assessment of the natural nuclei of local ecosomes of the Aleksandrovsky district (Donetsk region) in terms of their biological and ecosystem diversity, as well as their biocentric-network spatial structure. In this article, we estimate the potential migration links between local natural nuclei on the basis of the gravitational model of the similarity of the constituent geotopes of these nuclei. Based on the degree of similarity of the geotop structure of natural nuclei, the migration potential between them is determined, based on which spatial clusters of natural nuclei of the 1st, 2nd and 3rd orders are identified. It is concluded that natural nuclei forming clusters with a high level of migration potential, as well as their associations (clusters of the 2nd and higher order), should be given special attention in terms of environmental positions. And taking into account the concentration of these clusters in the hydrological network of the district, it is necessary to create PAs on each 1st and / or 2nd order watercourse at the expense of their natural nuclei with great environmental significance and a high degree of migration potential.

Keywords:  ecological networks, natural cores, migration potential, ecocorridors.
