Abstract
Ushbu maqolada Shimoli-g‘arbiy Qizilqum cho‘l ekotizimlarida o‘simliklar qoplamining 2000–2025-yillar oralig‘idagi fazoviy-vaqt dinamikasi geoaxborot tizimlari (GAT) va masofadan zondlash texnologiyalari asosida baholangan. Tadqiqotda o‘simliklar qoplamining holati va o‘zgarish tendensiyalarini aniqlash uchun NDVI, SAVI va MSAVI vegetatsiya indekslaridan foydalanilgan. Indekslarning vaqt bo‘yicha o‘zgarishi chiziqli regressiya asosida tahlil qilinib, trendning statistik ahamiyati p-qiymat va R² ko‘rsatkichlari orqali baholangan. Natijalarga ko‘ra, NDVI qiymati 2000-yildagi −0,731 dan 2025-yilda −0,989 gacha pasaygan va ushbu pasayish statistik jihatdan yuqori ahamiyatga ega bo‘lgan (p=3,38×10⁻⁸; R²=0,726). SAVI qiymati −0,427 dan −0,503 gacha pasayib, trend statistik jihatdan ahamiyatli bo‘lgan (p=0,00684; R²=0,267). MSAVI bo‘yicha esa −0,381 dan −0,423 gacha pasayish kuzatilgan, biroq trend statistik jihatdan barqaror bo‘lmagan (p=0,157; R²=0,082). Fazoviy tahlil o‘simliklar qoplamidagi o‘zgarishlarning asosan lokal va mozaik xarakterga ega ekanligini ko‘rsatdi. Tadqiqot natijalari Shimoli-g‘arbiy Qizilqum cho‘l ekotizimlarida o‘simliklar qoplamining holati va dinamikasini monitoring qilishda GAT va masofadan zondlash texnologiyalaridan kompleks foydalanish samarali ekanligini ko‘rsatadi.
