المستخلص

El-Qasr Village is considered one of the villages of El-Dakhla Depression that are most affected by sand dunes, which are characterized by continuous dynamic activity, particularly with the increase in human intervention represented, in turn, in the increase in the areas of cultivated lands. This change has a significant role in affecting its soil mechanically and chemically. This has been tracked by studying the movement rates of sand dunes, and their morphometric and morphological characteristics, as well as the factors affecting them, whether physical or human, which led to a decrease in their numbers and area. Furthermore, the study monitors the agricultural expansion along with the correlation between the dynamics of sand dunes and cultivated lands, which was reflected on their characteristics and capability, using the Land Evaluation program. Accordingly, suitable means were identified so as to increase its capability, and choose the best crops that are suitable for cultivation and that have a significant economic return in the region.
     تعد قرية القصر من أکثر قرى منخفض الداخلة تأثرًا بالکثبان الرملية والتي تتسم بنشاط ديناميکي مستمر وخاصةً مع زيادة التدخل البشري والمتمثل في زيادة مساحات الأراضي الزراعية، وکان لهذا التغير دورًا مهمًا في تأثر خصائص تربتها ميکانيکيًا وکيميائيًا، وتم تتبع ذلک عن طريق دراسة معدلات حرکة الکثبان الرملية وخصائصها المورفوومترية والمورفولوجية والعوامل المؤثرة فيها، سواء الطبيعية أو البشرية والتي أدت إلى انخفاض أعدادها ومساحتها، ورصد التوسع الزراعي والعلاقة الارتباطية بين ديناميکية الکثبان الرملية والأراضي الزراعية، والذي انعکس على خصائصها وقدرتها الإنتاجية وذلک باستخدام برنامج Land evaluation، وبناءً عليه تم تحديد الوسائل المناسبة لزيادة قدرتها الإنتاجية واختيار أفضل المحاصيل التي تتناسب زراعتها ولها عائد اقتصادي مهم بالمنطقة.
