Mazkur tadqiqotda Namangan viloyati suv havzalarida shakllanuvchi Cyanophyta florasining ekologik-tuzilmaviy xususiyatlari hamda uning suv ekotizimlari funksional holatidagi ahamiyati ilmiy adabiyotlar va hududning tabiiy-ekologik sharoitlari asosida tahlil qilindi. Cyanophyta vakillarining turli tipdagi suv obyektlarida tarqalishi, ekologik guruhlanishi, planktonik, bentik va perifiton jamoalar tarkibidagi ishtiroki hamda ularning muhit omillariga munosabati ko‘rib chiqildi. Tahlil natijalari Cyanophyta florasining shakllanishi suv havzasining gidrologik rejimi, yorug‘lik sharoiti, termik holati, suvning kimyoviy tarkibi va biogen elementlar bilan ta’minlanganlik darajasi bilan uzviy bog‘liqligini ko‘rsatadi. Ayniqsa, azot va fosfor birikmalarining suv muhitida ortiqcha to‘planishi, suv almashinuvi intensivligining pasayishi va qulay termik sharoitlar ayrim sianobakterial taksonlarning jamoada ustunlik qilishiga zamin yaratishi mumkin. Cyanophyta vakillarining birlamchi produtsentlikdagi ishtiroki, biogen elementlar aylanishidagi funksional roli hamda trofik holat o‘zgarishlariga javob reaksiyasi ularni suv ekotizimlarining ekologik holatini baholashda istiqbolli biologik komponent sifatida tavsiflaydi. Namangan viloyati suv havzalarida Cyanophyta florasini o‘rganish hududiy algofloristik xilma-xillikni aniqlash, ekologik jarayonlarni tavsiflash va kelgusida ilmiy asoslangan bioindikatsion monitoring tizimini shakllantirish uchun muhim nazariy va amaliy ahamiyatga ega.
