The height of the terrain is from 1100 to 4100 m above sea level. In addition to rivers, there are 19 glaciers and 8 small lakes on the territory of the Aksu-Zhabagly Reserve.
The soils are characterized by vertical zonation: in the alpine belt (3000— 4000 m above sea level), soils are fragmentary, in the subalpine (2000— 3000 m), dark—colored subalpine soils are common, in the forest meadow (1200-2000 m) — brown, in the foothills (below 1200 m) - gray-brown, gradually turning into typical sierozem soil.
