【 摘 要 】

The studied plantation is a post-mining sites of Kursk magnetic anomaly located in the northeastern part of Belgorod region in a iron-mining district of European part of Russia. The objects of this study are afforested external slope heaps produced by iron open-pit mine in Gubkin. Research work focused on 13-years old pure stands of birch (Betula pendula), sea buckthorn (Hippóphae rhamnoides), locust tree (Robinia pseudoacacia), oleaster (Elaeágnus angustifólia) and grey alder (Alnus incana) growing on the different substrates. Soil physical and chemicals properties of substrates were analyzed and forest litter stocks were calculated in different slope parts. Substrate quality varied considerably. Forest litter stock depends on site characteristics, tree species and substrate. Study results show that vegetation is the important factor facilitating soil development, the impact of forest litter stock that the surface structure determined is higher with such N-fixing tree species as alder, locust tree and oleaster.
