Mazkur tadqiqot ishi Farg‘ona vodiysi florasidagi Euphorbia turkum turlarining ekomintaqalar va balandlik mintaqalari bo‘yicha tarqalishini o‘rganishga qaratilgan. Euphorbia L. turkumi tarkibidagi 27 turning ekomintaqalar bo‘yicha tahlili natijalariga ko‘ra Hisor-Oloy ochiq o‘rmonzor, Oloy-G‘arbiy Tyan Shan dasht hamda Pomir-Oloy cho‘l va tundra ekomintaqalari turkum turlari uchun optimal ekologik muhit ekanligi aniqlangan bo‘lsa, balandlik mintaqalari bo‘yicha tahlil turkum turlari uchun adir, tog‘ va yaylov balandlik mintaqalari qulay muhit ekanligi aniqlandi.

This research work is aimed at studying the distribution of species of the genus Euphorbia in the flora of the Fergana Valley by ecoregions and altitudinal zones. According to the results of the analysis of the 27 species of the genus Euphorbia L. by ecoregions, it was established that the Hisor-Oloy open woodland, the Oloy-Western Tian Shan steppe and the Pomir-Oloy desert and tundra ecoregions are the optimal ecological environment for the species of this genus, while the analysis by altitudinal zones showed that the foothill (adir), mountain and pasture zones are a favourable environment for the species of the genus.

Целью данной исследовательской работы является изучение распространения видов рода Euphorbia L. во флоре Ферганской долины по экорегионам и высотным градиентам. Анализ 27 видов рода Euphorbia по экорегионам показал, что оптимальными экологическими средами для видов этого рода являются Гиссаро-Алайский редколесье, Алайская степь Западного Тянь-Шаня и Памиро-Алайская пустошь и тундра, а анализ высотных градиентов показал, что предгорные, горные и высотные градиенты пастбищных территорий.
