The article provides data on the inventory of the biological diversity of algae flora in water bodies of Southern Kyrgyzstan and its sustainable development. During 1998-2005, 2019-2023, we conducted a study of the biological diversity of algae flora in reservoirs of southern Kyrgyzstan, such as the Akbuury River and its tributaries, the Papan Reservoir, the Naryn and Kara-Darya rivers, hot springs, the Isfayramsay, Isfara, Shakhimardansay, Sokh , Aravansay, Naukatsai rivers, and also studied the flora algae of rice fields, fish ponds, treatment facilities, Aravanakbuurynsky, Otuzadyr, Yakkalyk, Jupas, Kayirma canals and others, which are located in three regions of Osh, Jalalabad and Batkent regions of Southern Kyrgyzstan. The results of the study show that in these studied years, when inventorying the algae flora of the reservoirs of southern Kyrgyzstan, 697 species, variations and forms of algae were discovered. During 1970-1995, B. Karimov studied the algae flora of reservoirs of southern Kyrgyzstan such as the Gulcha River, thermal springs, lakes Kulun, Karasuu, Sary-Chelek, ponds of the Uzgen fish farm, the basin of the Karadarya, Kara-Unkur, Karasuu, Akbuura rivers, as well the Kyrgyz-Ata, Abshirsai basins, the Kyzylsuu and Kurshab river basins, the Naiman and Turtkul reservoirs, as a result of the author’s research, 665 species, variations and forms of algae were discovered. For the first time, we combined the results of these two works - ours and the work of B. Karimova and compiled a general comparative floristic list of algae in the reservoirs of southern Kyrgyzstan. As a result of the inventory, it was found that 850 species, variations and forms of algae are common in the water bodies of southern Kyrgyzstan, of which the dominant leading divisions in terms of quantity are Bacillariophyta, which has 464 species, variations and forms of algae, followed by the subdominant divisions - Chlorophyta (177), Cyanophyta (165), in other divisions of algae the number of species is very scarce (Euglenophyta - 12, Xanthophyta - 10, Chrysophyta - 7, Pyrrophyta and Rhodophyta - 6 each, Charophyta - 3). To preserve the natural riches of the algae flora of water bodies and their sustainable development, it is recommended to protect water bodies from incoming contaminated wastewater containing toxic chemicals.
