Tasks of the master's thesis: to determine and analyze the taxonomic composition of diatom algae of water bodies of Chirchik city;
- Determination of seasonal succession of diatom algae of city water bodies;
-Determination of quantitative changes in the composition and biomass of diatom algae of city water bodies;
- To study the dominant species and ecological groups of diatom algae in urban water bodies.
Scientific novelty of the research: The species composition of diatom algae in natural and artificial water bodies in Chirchik was studied for the first time, and during scientific research, 2 classes, 4 orders, 4 orders, 10 families, 32 genera and 200 species of diatom algae were found. type was identified. Information on ecological groups of diatom algae of water bodies of Chirchik city was obtained and analyzed. Seasonal succession and dominant species of diatom algae in water bodies of Chirchik city were determined. Information on the amount of diatom algae in the city's reservoirs and their seasonal succession was obtained.

Biologik xilma - xillik Yer biosferasining muhim sifatlaridan biri hisoblanganligi tufayli unga zarar yetkazishning oldini olish va to‘xtatish uchun tirik organizmlar, xususan, suvo‘tlari, ularning tarqalishi, rivojlanishi, shuniningdek, tarkibi haqidagi bilimlarimizni kengaytirishimiz zarur. Suvo‘tlari tabiatda keng tarqalgan bo‘lib, ulardan nihoyatda ko‘p biomassa hosil bo‘ladi. Uning kimyoviy tarkibi har xil bo‘lganligi sababli inson va hayvonlar hayotida katta rol o‘ynaydi. Suvo‘tlari xalq xo‘jaligining turli soxalarida keng qo‘llanilib, sanoat uchun muhim xom- ashyolardan biri hisoblanadi. Dunyo bo‘yicha suv havzalari algoflorasi olimlar tomonida o‘rganilib kelinmoqda. Ularning ma'lumotlariga qaraganda Sitnik, Ibar daryolarida 112 (Urosevik, 1991), Limay daryosida 15 (Guarrera, Echenique, 1991), Samborambon daryosida 132 (Claps, 1991), Kolima daryosida 934 (Xaritonov, 1991), Dnestr daryosida 707 (Zubku, 1980), Yenisey daryosida 633 (Levadnaya, 1986), Ob, Irtish daryolarida 338 (Naumenko, 1985), Irtish daryosida 297 (Valiyeva, 1975) suvo‘tlarining tur va tur xillari mavjudligi bayon etilgan.
