Зональность озер Алтая

Аннотация

Zondity of lakes in the Altai region is determined by 1) their genetic links with river erosion, 2) vertical zonality of glacial-nival and frosty-Solitluction belts of mountains, 3) layering of ancient planation-surfaces, 4) the type of plain .lakes: base for inner off-flow or lake without outlet. From mountains towards plains periglacial lakes are changed to fluvio-erosional ones, oligotrophic to mesotrophic and eutrophic lakes, freshwater to brackish- and salt-water lakes.
