Abstract
The purpose. To evaluate potential productivity of agricultural lands on the basis of method of model simulation of conditions of water-land-use in view of probable climate fluctuations within the limits of Kahovsk and Chaplinsk areas of Kherson oblast for justification of restoration and development of irrgi ation in these terrains. Methods. Analytical, statistical, imitating (simulation), method of system analysis. Results. As a result of typification of the pilot terrain typological ranges with homogeneous soil-climatic conditions are allocated. Simulation of potential productivity of lands on each typological range is executed by means of dynamic model of production process WOFOST on an instance of corn. The assessment of productivity of lands is based on results of simulation of the built scripts of water-land-use with various natural-economic conditions. Conclusions. The method of simulation of scripts of water- land-use has allowed to note various factors of influence on formation of potential productivity of lands on an instance of corn for grain under different natural-economic conditions, and also to select economic and ecologically safety alternative of restoring irrigation.

Key words: typification of terrain, simulation, potential yielding ability of corn, productivity of lands, scripts of waterland-use
