هدف الدراسة: تهدف هذه الدراسة إلى تقييم التأثير الجيومورفولوجي غير المباشر للإنسان الناتج من التخييم في صحراء دولة الكويت على كثافة نبات الثندى. المنهج: وظفت عدة منهجيات في هذه الدراسة؛ مثل استخدام اسلوب الجمع الميداني للبيانات وذلك من خلال تقسيم مناطق المخيمات إلى شبكة من المربعات المتساوية، ومن ثم استخدام جهاز اختراق التربة المحمول لتسجيل قراءات انضغاط التربة، بالإضافة إلى أسلوب العد لحصر عدد نبات الثندى، وفي النهاية أجري تحليل للبيانات التي جمعت إحصائياً. النتائج: وجد أن انضغاط التربة في المواقع التي لا يوجد فيها مخيمات أقل بكثير من مواقع التخييم، وأن كثافة نبات الثندى أكبر بكثير في المواقع التي لا يوجد فيها مخيمات مقارنة مع مواقع التخييم؛ أما بالنسبة لعدد المربعات في كل مخيم، فقد وجد أن غالبية مربعات الشبكة تحتوي على كثافة عالية من نبات الثندى في المواقع التي لا يوجد فيها مخيمات وذلك على عكس مواقع التخييم. وباستخدام معادلة الانحدار اللوجيستي، وجد أن هناك علاقة عكسية ما بين انضغاط التربة ودرجة كثافة نبات الثندى. الخاتمة: اتضح من نتائج الدراسة أن التخييم يعتبر أحد أسباب انضغاط التربة، الذي يؤثر بشكل سلبي على كثافة نبات الثندى في صحراء الكويت.
