On example of the river basin Kashkadarya are choose representational plots with the help of GPS and is realized sampling in 55 points. Laboratory analysis allows revealing some regularity and work out GIS - heavy metals of the region. Also are provided for developing of the technical decision is provided on sanitation of soils. Key words: heavy metals, system "water-soil", representational plots, land sanitation, excavation, desalinization and readjustment soils, GIS technology Introduction On the monitoring of Nature protection The studying of heavy metals in soils, committee of the Republic of Uzbekistan is underground and surface waters concerned installed excess possible standards (the Bul- with many scientists Johansson K., Anders- letin board.
