Abstract

Research objective is justification of the meliorative modes at complex arrangement of reservoirs of a steppe zone of the Western Bashkortostan on the basis of references and results of researches. The common modern situation of territories of Russia including the Republic of Bashkortostan, it is characterized by rather intense ecological state. Reservoirs of a steppe zone possess the lowest degree of ecological stability. One of paths of increase in their ecological stability are complex arrangement which one of the main receptions pro- vides carrying out water managements with keeping of the indicators demanded for this zone meliorative the modes. Justification of the meliorative modes at complex arrangement of reservoirs is executed on the basis of model operation of functioning of reservoirs of a steppe zone of the Western Bashkortostan according to the Catena program. By results of model operation of functioning of reservoirs of a steppe zone in the Catena program recommen- dations for reservoirs of a steppe zone are developed. On them the regular irrigation of all fatsias is recommended. To carry out waterings with preirrigation humidity 0,72 PPV.  Drainage the superakvalnykh of fatsias with norms to  1,9 m is recommended. The relative efficiency of reservoirs as a result of water managements will increase by 3,3 times. Change of components of a local drain after melioration in all groups the favorable.
