WATER SOIL EROSION IN RIGHT-BANK UKRAINIAN FOREST-STEPPE ZONE

Problem Statement and Purpose. A water soil erosion is one of the most important ecological problems world because in result it cover completely destroys not able to renew for a long time. In opinion dr. Montgomery D., loses agricultural soils even limited lifetime ancient civilizations same problem closely touches today human being. Following information scientists 1970-s, about 430 million ha lands were destroyed different countries erosion. Annual product on our planet equal 5–7 ha. Ukraine at end first decade 2000s following National report (2010) square eroded equaled 15.954 or 38.4 per cent their common territory including 12.940 arable 39.9 cent. On average approximately 15 t/ha/year. Thereby purpose study spatial distributed quantitative assessment intensity right-bank forest-steppe zone definition squares with rates load considering present climate changes land use peculiarities. Data &Methods. For estimation wash off three typical slope plots (К1-р, К2-р, К3-р) used. The are situated within Educational Scientific Stationary Odesa I. Mechnikov University that Podilsk district north part region. This south hills Podolska upland zone. parts small valleys slopes which annual plowed up used growing profit-making crops – wheat, corn, barley sunflower. No any scientifically based crop rotation uses there least last twenty years. physical statistical model accumulation was as working consideringthe peculiarities cultivation anti-erosion properties. developed Department Physical geography, Nature Management Geoinformation Technology realized GIS‑package PCRaster (Utrecht University, Netherlands). Results. demonstrates very high rate degradation obviously representative territories Ukraine. Areas more than 20 t/ha/year 23–27 less 2 where equals restoration third all lands. values К1-р, К3-р 14.2; 26.3 14.8 respectively. However, these above ones obtained earlier, but some less. due decreasing snow melting spring connected global warming. But simultaneously hydrometeorological conditions rainstorm have change. And essential has happened only 15–20 huge significant areas (about lands) evidence economic worth commonly. Applying protection well influence plowing great (6–7° more) using them row without leads catastrophic increasing danger. Such need be exclude up.
