Optimization of technogenic landscapes of the Crimea. Report 1. Quarries and pits

Abstract

The main forms of anthropogenic relief formation (defensive ditches, mounds, canals, quarries, dumps, etc.) from the Neolithic to the present, which were marked by the presence of 152 abandoned and 137 active quarries on the territory of the peninsula, are considered. The basic principles and approaches to the reclamation of anthropogenic landforms are stated. Improvement options should be determined by the specific conditions of the technogenic landscape, as well as the suitability of the quarry for the intended use and the possibility of its transformation and, of course, the need of the ecosystem and society for an optimized object of the proposed type. The versions of optimization of open-pit workings during dry and wet rock excavation are considered. It is noted that in conditions of water shortage, preference should be given to the creation of reservoirs at the place of workings. The basic requirements for reclamation for agricultural and forest lands, the formation of sozological reserves by the formation of artificial reservoirs for various purposes: a reservoir to maintain ecological balance and preserve biological diversity (landscape-ecosystem function), a reservoir as a recreation area (recreational function), a reservoir as a source of drinking water (hydrological function), a reservoir for fish farming, including professional fishing (economic function). Possible approaches to optimization of quarries are discussed. An assortment of plant species suitable for creating coastal communities with a coastal protection function is presented.
