Abstract. In Russia, including in the Volgograd region, abnormal weather conditions (extreme droughts, dry winds, dust storms, spring floods, hurricane rains) destabilize agricultural production, lead to the degradation of agricultural land. This creates the prerequisites for the restoration and further development of the land reclamation of problem areas, including field-protective afforestation. In the conditions of transition to market relations, the financial support of forest reclamation projects requires the accuracy and reliability of the estimate and design documentation, an important part of which is to determine the scope and structure of the costs of creating protective forest plantations as capital construction objects. These data serve as the basis for calculating the effectiveness of forest land reclamation of arable lands in general. The article gives the estimated cost of creating shelterbelts (windbreak and runoff-regulating) forest belts in modern prices, adequate to the natural and climatic conditions of the Volgograd region. Dynamics of costs for field arrangement by forest belt systems is given depending on the method of their production (sowing, planting), the projected level of protective forest cover of forests, biotechnological features of plantations, and orographic conditions of the agrarian landscape. It is established that the main factor affecting the amount of costs is the protective wooded land. In deflation-dangerous agrolandscapes, it is determined by the natural zone and the protection of fields, erosion- dangerous – the natural zone and locality incline. So, the estimated cost of creating 1 hectare of windbreak and runoff-regulating forest belts on the non-washed soils is 96–115 thousand rubles, on washed-away soils it is 15–28 % lower. Specific capital intensity of forest reclamation arrangement of 1 hectare of deflation- dangerous agrolandscapes equals 2.1–8.9 thousand rubles, erosion-dangerous (together with the simplest hydro-constructions) – 2.4–5.4 thousand rubles per 1 ha of forest reclaimed land.
Keywords: soil deflation and erosion, windbreak and runoff-regulating forest belts, natural zone, protective wooded, locality incline, range of breeds, cost, economic evaluation.
