The present research paper deals with the reasons leading to land of the Steppe which include over -grazing and shrubs cutting for fuel more over soil erodibility wich is caused by the week structure and light texture of the soil s of the Steppe. As a result wind erosion become a prevailing process in the Steppe .This phenomenon was remarkably accelerated during the last decade. The result of this research paper also presented detailed analysis for frequance appearance of the dust storms according to the months and years its relationship with - drought and area of eroded soils in the eastern Syrian Badia.

The results showed numbers of dust storms during 1984 to 2009 were at the end of spring and beganing autaum. The results elso indicated that the dust storms were associated with drought cycle occurred in Syria especially during 1987,(1999-2000),(2008 2009). It was noticed that amount 115 dusted dyas.

In 1991 year, out of this number 27 dyas were in june month .However, in 2008 year ,There were 74 storms during that the visibility was 100m, it was shown that the amount of dust carried with storm on 31/4/2011 was 35.5 million tones. The Hot Spots of the dust storms appearance were noted in the middle of the Syrian Badia and especially in the cultivated area , for Example , AL Rasafa steppe and AL-Qasser Alher alshargy and AL-nasseria Plains.

يتناول البحث تحديد العوامل الأرضية والمناخية المسببة لظهور العواصف الغبارية في شرق البادية السورية وارتباطها بالإدارات الخاطئة لهذه الأراضي والمرتبطة بفلاحة أراضي المراعي الطبيعية في البادية وغياب برامج إدارة المراعي.
