SIRDARYO DARYOSI HAVZASI SUV RESURSLARI BILAN TA’MINLANGANLIKNING MAKON-VAQT O‘ZGARISHINI GEOAXBOROT TIZIMLARI ASOSIDA BAHOLASH
Abstract
Maqolada Sirdaryo daryosi havzasi uchun iqlimiy, gidrologik, suv xo‘jaligi va fazoviy ma’lumotlarni yagona tizimga birlashtiruvchi geoaxborot ma’lumotlar bazasini shakllantirish metodikasi va uning asosida suv resurslari bilan ta’minlanganlikning makon-vaqt o‘zgarishini baholash natijalari bayon etilgan. Ma’lumotlar bazasi uchta vaqt blokiga ajratilib, har bir qiymatga kelib chiqish holatini ko‘rsatuvchi belgi biriktirildi; raqamli relyef modeli asosida subhavzalar ajratildi va ArcGIS Pro muhitida 2000, 2005, 2010, 2015, 2020 va 2025-yillar uchun yagona sinf chegaralariga ega besh darajali ta’minlanganlik xaritalari tuzildi. Ta’minlanganlik tog‘li yuqori oqimdan quyi oqim tomon izchil pasayishi, 2010 va 2015-yillarda qulay zonalar kengaygani, 2020-yilda esa past va juda past ta’minlanganlik zonalari quyi oqimdan o‘rta oqim tomon siljigani aniqlandi. Eng o‘zgaruvchan hudud o‘rta oqimdagi sug‘oriladigan yerlar, eng zaif hudud esa quyi oqim ekani ko‘rsatildi.
