The basic theme and subject of researches are reclaimed agrolandscapes of low reaches of the Syr Daria of Kazakhstan which are characterized by the unsatisfactory ecological-reclamation state. The aim of the researches is to analyze and assess the ecological-reclamation state of anthropogenically polluted lands of the Syr Daria lower reaches for substantiation and development of urgent measures on reducing a negative influence and improvement of the ecological situation in this region. The result of the fulfilled work is the survey of the researches on the analysis of the revealed reasons of worsening of the ecological-reclamation state of the irrigated lands of the South of Kazakhstan. On the basis of the data of the reclamation cadastre there is given an assessment of the present state of the lands of the Syr Daria lower reaches and developed principal directions on improvement of the ecological-reclamation condition of anthropogenically broken lands. Researches in the natural complex «Akuum» of the Zhalagashsky region of the Kzyl-Ordinskaya area showed that a large territory is occupied by the lands with a medium and very high salinization degree of a meter thickness of aeration zone. There is noted an evident reduction of lands with a ground water table < 5,0 m, extension of lands with a not too deep bedding of water table (< 2,0 m), increase of areas with mineralization of ground water > 3,0 g/l and decrease of areas with mineralization < 1,0 g/l. On the basis of the performed analysis and fulfilled researches of the territory of the southern Kazakhstan there are discovered priority directions on improvement of the ecological-reclamation state of the lands of the Syr Daria lower reaches.
