چکیده

این مطالعه به منظور بررسی اثر تغییر کاربری اراضی و موقعیت زمین‌نما بر برخی از ویژگی‌های خاک در بخشی از اراضی تپه ماهوری شهرستان یاسوج انجام گرفت. در این منطقه از سه کاربری جنگل طبیعی، جنگل تخریب شده و زراعت دیم و در هر کاربری از سه کلاس شیب 10-0، 20-10 و 30-20 درصد و در هر کلاس از 5 نقطه به صورت تصادفی، جمعاً در 45 نقطه از عمق 10-0 سانتی متری انجام گرفت. نتایج نشان داد که میانگین ماده آلی در کاربری جنگل طبیعی (8/5 درصد) به طور معنی‌داری (01/0 p
