Abstract
Sirdaryo viloyati O‘zbekistonning muhim qishloq xo‘jaligi hududlaridan biri bo‘lib, sug‘oriladigan yerlarda vegetatsiya qoplamining mavsumiy o‘zgarishlari va NDVI (Normalized Difference Vegetation Index) indeksi GIS va masofadan zondlash texnologiyalari yordamida o‘rganildi. Landsat 8/9 sun’iy yo‘ldosh tasvirlari asosida 2024 yil 24 mart va 30 iyul kunlari uchun vegetatsiya holati tahlil qilindi. Natijalar bahor davrida past NDVI qiymatlari (asosan <0.1, vegetatsiya dormansi) va yozda yuqori qiymatlar (0.4 gacha, faol o‘sish) o‘rtasidagi sezilarli o‘zgarishlarni ko‘rsatdi. Bu o‘zgarishlar sug‘orish sikli, tuproq sho‘rlanishi va suv taqchilligiga bog‘liq. Tadqiqot masofadan zondlashning vegetatsiya monitoringidagi samaradorligini ta’kidlaydi va barqaror qishloq xo‘jaligi strategiyalarini ishlab chiqishga hissa qo‘shadi. Ushbu ish PhD dissertatsiyasi va Scopus/Web of Science jurnallarida chop etish uchun moslashtirilgan.References
