Opis:
This study provides original data on the impact of human activity on vegetation under the specific conditions of the Kastanozem from the Kostanay region (northern Kazakhstan). Radical changes in land use are provoking deposition in vegetation. The question remains whether natural vegetation will return or whether a different type of vegetation will be created under the specific conditions of the Kastanozems soils. The evaluation of vegetation took place in the fields that were abandoned in different time horizons. Height, cover, biomass weight and species composition of vegetation were monitored. The vegetation of abandoned fields is characterized by low species diversity. Succession runs from annual species to a stage where perennial dicotyledonous species with a deep root system dominate. Spontaneous vegetation leaves a sufficient amount of biomass on the soil surface, which assumes that the land will be protected from undesirable phenomena such as erosion and desertification processes.

Opis:
The article provides a comparative analysis of the flora and endemism of the western and eastern part of the KetpenTemerlik range in Kazakhstan and China, which is the eastern tip of the Northern Tian Shan. The flora of the entire Ketpen-Temerlik range includes 1890 species of vascular plants belonging to 593 genera and 120 families. In the western part of the ridge (in Kazakhstan), 1747 species were identified, belonging to 585 genera and 111 families and in the eastern part (in China), 1673 species belonging to 577 genera and 117 families. Angiosperms make up 98.4% of the ridge flora, 80.0% of which are dicotyledonous and 18.5% are monocotyledonous. The analysis of the largest flora families of the entire Ketpen-Temerlik range allowed us to identify 28 of the largest families by the largest number of species. The families with the largest number of species are Asteraceae (308 species), Poaceae (166), Fabaceae (133), Brassicaceae (105), Caryophyllaceae (93), Rosaceae (90), Lamiaceae (81), Chenopodiaceae (75), Ranunculaceae (74) and Scrophulariaceae (57). The major genera are Astragalus (43 species), Artemisia (38), Taraxacum (34), Carex (33), Allium (33), Potentilla (31), Ranunculus (22), Oxytropis (21), Veronica (20), Poa (18), and Saussurea (18).

Opis:
This paper presents an assessment of changes in maximum flow values (maximum discharge, m3/s) of the spring flood caused by human activities on the rivers Zhayyk, Ilek and Tobyl. Statistical characteristics of the maximum discharge of the spring flood of these rivers for the period of 1940-2012, 1938-2012, before and after the construction of the reservoirs, as well as for the long-term period of supervision were analyzed based on the actual as well as restored data. The values of the maximum discharge of the spring flood of various provisions were calculated. The total integrated curves of the maximum discharge of the spring flood were constructed.
