Abstract. We have carried out computer reference images to geographic coordinates, saved in a separate layer and is combined with a layer of digitized topographic maps. Determining the level of degradation was carried out by the statistical average values of phototone image, and take into account the range set for each type of soil (sand) in the evaluated areas.

Technology phytomeliorative works was determined taking into account the characteristics of sites, their technical condition, degradation, elevation, transportprojekte and is contained in the schemas working draft.

On the technological scheme was carried out a manual landing on the medium and krupnoblochnyh the Sands with a height of sand ridges, dunes, barchan chains of 3–7 meters or more, with deep hollows blowing netratarpana difficult terrain, danger of tipping aggregates and forestry machines. In case of manual planting, the layout of the seedlings (seedlings) Calligonum (5,0 ´1,5)–1 333 m/ha. Manual stop of Calligonum is protected by the decomposition along the length of the landing roll of reeds. Device ordinary protections of a cane will serve for protection from blowing and drifting sand of the seedlings after planting and during vegetation and their rooting.

The ordinary protection device made of reeds prevents the sand drift seedlings after planting, in the period of early vegetation and rooting and contributes to the accumulation and preservation of moisture in the thick sand root zone during the vegetation period. This all eventually led to increase the survival rate of Calligonum and its development.

Key words: manual planting saplings of Calligonum, manual planting of seedlings, exposed shifting Sands, cartographic and aerospace monitoring, degradation of agricultural lands in arid zone.
