ИҚЛИМ ЎЗГАРИШИ ШАРОИТИДА ЭТАЛОН ЭВАПОТРАНСПИРАЦИЯНИ ҲИСОБЛАШ: УСУЛЛАР ТАҚҚОСЛАНИШИ ВА АМАЛИЙ ЁНДАШУВЛАР

Ушбу тадқиқотда иқлим ўзгариши шароитида эталон эвапотранспирацияни (ET₀) баҳолаш усулларининг самарадорлиги ва аниқлиги комплекс тарзда таҳлил қилинди. Тадқиқотда Харгривз, Турк, Блэни–Криддл ҳамда Пенман–Монтейт (FAO-56) усуллари, шунингдек сунъий йўлдош маълумотларига асосланган Manna иловаси натижалари ўзаро таққосланди. Таҳлиллар 2021–2023 йиллар давомида Тошкент вилояти Ўрта Чирчиқ туманида жойлашган Туябоғиз метеорологик станцияси маълумотлари асосида амалга оширилди. Усуллар ҳисоблаш аниқлиги, талаб этиладиган маълумотлар ҳажми ҳамда маҳаллий арид иқлим шароитида қўллаш имкониятлари бўйича баҳоланди. Натижаларга кўра, PM-CROPWAT усули бўйича вегетация давридаги эталон эвапотранспирация миқдори 935,68 мм ни ташкил этди, Manna иловаси эса 706,60 мм қийматни кўрсатди (фарқ −24,5%). Харгривз ва Турк усуллари мос равишда +87% ва +77% даражада юқори баҳолашни кўрсатди. Manna ва CROPWAT натижалари ўртасидаги корреляция коэффициенти R²=0,913 бўлиб, бу улар ўртасида юқори боғлиқлик мавжудлигини кўрсатади. Тадқиқот натижалари шуни кўрсатадики, FAO CROPWAT 8.0 дастури эталон эвапотранспирацияни ҳисоблаш ва суғориш режимларини режалаштиришда самарали инструмент ҳисобланади. Олинган натижалар сув ресурсларидан оқилона фойдаланиш ва замонавий суғориш тизимларини оптимал бошқариш учун муҳим амалий аҳамиятга эга.
