The development of the extractive industry leads to the increase in the number of quarries on the territory of the Crimean peninsula and, as a consequence, to the increase of the area occupied by the disturbed lands requiring recultivation. The reclamation of such land plots on the basis of creating the necessary conditions for the development of regenerative successions of zonal vegetation on them and ultimately the formation of soils is much cheaper for land users. Therefore, studies of the rates of soil formation, including using the methods of mathematical modeling of the processes of formation of the humus horizon of the soil over time, have become relevant. Calculation of the economic efficiency of reclamation of the disturbed lands has been carried out for the Alexandrovskoye saw- limestone field in the Chernomorsky region of the Republic of Crimea. The assessment has been carried out within the framework of two models: mining engineering with further self-overgrowing of the reclaimed land plots under pastures and integrational, including both mining engineering and biological stages with possible carrying out a number of agrotechnical works on further improvement of pastures, based on the calculation of the cost-effectiveness indicator. This indicator is based on the selection of the best options for remediation work at the minimum value of the integral operational and investment costs and takes into account the effect of the time factor. The calculation results have shown that, in terms of cost-effectiveness, it is more rational to use the mining engineering model with further self-overgrowing of the sites to be reclaimed when it comes to the reclaiming of the disturbed lands of the Alexandrovskoye quarry.

The most important task of the economic theory is to develop an adequate anti-monopoly policy and create a competitive environment in the industry market. For the modern economic conditions of the Crimea, the development of competitive relations and the containment of restrictive practices have most clearly been implemented in the mining and construction industry, which has a good production base, a wide market and sufficient information. Moderate level of concentration of the capital in the industry of production of construction and mineral raw materials in the conditions of the presence in its mining enterprises economic profit leads to the conclusion that modernization and innovatization of technical and technological base of the industry and increase of the scale of production are possible only through the development of the competitive environment, influencing the institutional component.

The Herakleian Peninsula has a unique geographical location and a long history of development. The methods of historical and geographical research of this territory have been considered. The historical landscapes development dynamics research of the Peninsula has been conducted with the use of cartographic material, satellite images interpretation and a field observations of the territory within the selected time slices. Map analysis of the economic subsystem of the anthropogenic landscapes of the Herakleian Peninsula has been made. Areas of the South -Western and North-Eastern parts of the Peninsula which preserve the historical features of the modern land use formation have been singled out with regard to the specifics of the arrangement of land allotments (klers) in the ancient system of agriculture.

The article sets forth a generalized understanding of economies of scale in agrarian production as a complex integrative phenomenon, implemented in a unity of three components-the intra-branch scale effect in agrarian production, the quality effect, the number of enterprises and the effect of their average scale production. The author's translogarithmic model of economies of scale and the approach to its optimization have been proposed. Specific, potential determinants of the high cost of agricultural products based on the assessment of trends in economies of scale and the level of technological efficiency in the specialized Crimean production units have been established. A parametric analysis of the economies of scale in the model of factor-resource potential has been constructed in the framework of the boundary stochastic function of agrarian production in order to ensure an adequate level of technological efficiency. The ways of increasing of the branch effectiveness and technological efficiency of the agrarian formations of Crimea have been proposed. 1. Introduction
