The article discusses aspects of developing an algorithm for flood zones modeling using modern geographic information technologies in the area of the river near the town Petrovsk. The integrated approach to the flood zones modeling of different hydrological magnitude is considered. As a result of the developed algorithm application, flood risk areas with different probabilities (1, 5, 25 and 50%) with an indication of the depth of flooding are identified.

The issue of spatial planning includes the subject of taxonomy. It seems that it is necessary to switch to the practice of planning, in addition to the meso-level (subject of the Russian Federation), at two taxonomic levels: the macroregion and the economic microdistrict. To do this, the article identifies the main properties of these formations. On the example of the Volga-Ural macroregion the properties of integrity, complementarity and connectivity are analyzed.
