Abstract
Mazkur maqolada O‘zbekiston Respublikasi Qizil kitobining so‘nggi 2019-yildagi nashriga kiritilgan Asteraceae oilasi vakillarining tarqalishi, ekologik xususiyatlari va muhofaza holati tahlil qilindi. Tadqiqot obyekti sifatida oilaning 17 turkumiga mansub 43 ta kamyob, endem va yo‘qolib ketish xavfi ostidagi turi o‘rganildi. Natijalarga ko‘ra, o‘rganilgan turlarning aksariyati tor arealli va ekologik jihatdan cheklangan muhitlarga moslashgan bo‘lib, ularning asosiy qismi 1-, 2- va 3-toifalarga mansub ekanligi aniqlandi. Shuningdek, ayrim turlar uchun muhofaza choralarining yetarli darajada ishlab chiqilmaganligi qayd etildi. Tahlil jarayonida turlar soni va arealining qisqarishiga sabab bo‘layotgan asosiy xavf omillari sifatida chorva mollarining nazoratsiz boqilishi, yerlarning qishloq xo‘jaligi ehtiyojlari uchun o‘zlashtirilishi, dorivor o‘simlik sifatida nooqilona va me’yoridan ortiq yig‘ib olinishi, texnogen ta’sirlar hamda iqlim o‘zgarishi bilan bog‘liq omillar ajratib ko‘rsatildi. Bundan tashqari, 8 ta tur bo‘yicha asosiy xavf omillari aniqlanmaganligi va ularning ekologik holati yetarli darajada o‘rganilmaganligi qayd etildi.References
