Abstrak
Maqolada Sangzorsoy havzasida tuproq eroziya jarayonlarini geoaxborot tizimlari va zamonaviy empirik modellardan foydalangan holda kompleks baholash natijalari keltirilgan. Tadqiqotda relyef, tuproq qoplami, iqlim omillari, o‘simlik qoplami va eroziya darajasiga ta’sir ko‘rsatadigan antropogen bosimlar tahlil qilindi. Miqdoriy baholash uchun masofaviy zondlash ma’lumotlari va raqamli relyef modeli bilan integratsiyalangan RUSLE modelining modifikatsiyasi qo‘llanildi. Eroziya jarayonlarining fazoviy qonuniyatlari aniqlanib, yuqori xavfli hududlar belgilandi. Tuproq barqarorligini oshirish va degradatsiyani kamaytirish bo‘yicha ilmiy asoslangan choralar taklif etilgan.
