Abstract: The main factors of dust storms rise are recurrence of strong winds and vast area of dust emission sites, where the latter is the subject of change. During the last decades owing to the crisis situation in the Aral region the total area of dust emission sites increased significantly because of the shrinking of the Aral Sea and consequent drying of its exposed bottom and deltaic areas of Amudarya and Syrdarya Rivers (Orlovsky et al 2004). The Aral Sea problem has formed by the relations between humanity and nature and human attitude without affection by seeking to development to the environment. During the one generation life the Aral Sea had already dried and there is a desert instead of it. Under conditions of the Aral Sea ecological crisis, natural ecosystems within a 400 km radius of the seashore have undergone transformations. In region of Aral Sea crisis cause many problems depends and affects each other. In my research I point out one problem in this region dust storms and dust transfer. The aim of this research approach is to analyses spatial and temporal distribution of dust deposition in the southern Aral Sea region. Dust occurrence and its effects lead to the modification of the mineral structures of the arable land. Productive soils are degraded and salinized the agricultural productivity is decreasing. study the influence of negative chemical elements in soil.
