Subjects of research: vegetation types of Zaamin basin. Purpose of work: to investigate phytocenological variety and areal spreading of vegetation types of Zaamin basin and to conduct a modern map of the region. Methods of research: traditional field-routing, geobotanical and cosmic imagery methods. The results obtained and their novelty: phytocenological variety of Zaamin basin has for the first time been investigated and 6 types, 9 subtypes, 19 cenotypes, 27 formations, 85 associations have been revealed in 4 zones. 5 associations in the basin were newly described. The map of vegetation cover of Zaamin basin in large scales (M 1:200000) and multi-level definition have been developed. 36 topological and anthropogenetic modifications and degree of decreasing have been shown by indexes (А, В, C). 516 types belonging to 249 subtypes and 61 families have been registered. Practical value: results of these investigations can be used in planning of preparing meadow, plant and forest raw materials, reconstructing endangered plant types and protecting the genfond of the region under investigation. Degree of embed and economic affectivity«The map of Vegetation Types of Zaamin basin» (M 1:200000) and developed recommendations were given to the Dzhizak province of the State Committee of the Nature Protection (act № 1396, 12.12.2011) and Geoinformcadastre state unitary organization of Land resources, geodesy, cartography and state cadastre of Republic of Uzbekistan (act № 2, 6.03.2012).
