METHODS OF URBAN ORGANIZATION AND REGENERATION OF RIVER ECOSYSTEMS OF POLISYA

Rivers of Ukraine are divided into 3 types: Polissya, mountain and rivers dissected valleys. The attention this article is paid to the analysis natural features river ecosystems reasons factors their degradation. Methods town-planning organization regeneration coastal territories Polissya-type urban suburban zones offered. current state Polissya considered, degradation made. Proposals have been made for planning areas in areas.
 weakly expressed wide valleys with a significant width floodplain. height small (about 1 m), which contributes frequent flooding waterlogging. In channels, mostly composed sand, strands common. curved areas, ravines formed, convex spit. speed flow insignificant 0.2-0.3 m / s. water clear brownish tinge due presence swamp water. do not dry up. There relatively few aquatic air-water vegetation rivers. forest cover 20-40%; there share wetlands reclaimed areas. dominated by coniferous mixed forests pine birch on sandy loamy soils, chernovshnyak swampy soils terraced depressions.
 largest Pripyat Desna; Berezina Sozh somewhat inferior them. Most lowland belongs basin River, originates within Volyn region, then passes territory Belarus again Ukraine. Desna second level River.
 near Russian city Yelnya. has fairly floodplain most parts proximity mouth Kiev determines health recreational function area Desna. Desnianska main source supply Kyiv. characterized depth cut-offs intakes, gradual transition from intensively floodplains terraces low watersheds. ravine-beam relief geomorphological expressiveness ecosystem naturally balanced formation - disturbance directly affects riverbed. Maintaining (optimal) functioning its catchment helps increase self-cleaning capabilities minimize impact extreme situations, including low-water years. Any measures preservation or reconstruction valley should be aimed at reproduction complexes, originally characteristic landscape.
 order maintain, preserve, protect restore ecological balance, take account number wetlands, plants. ecosystems. dominance landscape direction will help maintain key maintaining purity stability
