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:
The paper considers the approaches and possibilities of using two types of simulation: the species distribution model and the ecological niche model. The study aimed to simulate favorable habitats and the potential spread of non-gregarious locust pests in North Kazakhstan based on satellite and ground data for preventive measures. The MaxEnt software was used to conduct the simulation. According to the species distribution model, high indicators of the habitat are predicted in the Pavlodar and Kostanay regions, on 69.9–100% of the studied territory. With the simulation of ecological niches for non-gregarious locust pests, the following class boundaries were determined for the transition from quantitative to qualitative indicators from I (85–100%) to IV (0–50%), which indicates the zones of the probability of pest attack from a higher indicator to a lower one. According to the fundamental model, high indicators of the area of pest occurrence, that is, zones I and II, are located in the central and northern parts of the Pavlodar region. Here, the probability of non-gregarious locust occurrence of zone I and II with a ratio of 1:1 is observed in a slightly arid, moderately warm agro-climatic zone. In the southern part of the Kostanay region, the simulation predicts the probability of occurrence on zones I and II with a ratio of 1:2 in the moderately arid warm agro-climatic zone of this region. In the southern and southeastern parts of the Akmola region, the model predicts the probability of occurrence in zones I and II with a ratio of 1:3 in a slightly humid, moderately warm agro-climatic zone of the region. The considered species distribution model can be used as a modern tool for long-term forecasting of the spread of non-gregarious locust pests since it takes into account the peculiarities of the agricultural landscape. The fundamental niche model can be used in a long-term population forecast since it focuses more on the theoretical conditions of pest habitats.

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.

Opis:
The West Kazakhstan region of the Republic of Kazakhstan occupies an area equal to 151,339 km2. In the land structure, 69.7% of the area is occupied by agricultural land. The region has great prospects for the development of the livestock industry. However, uneven territorial availability of water resources is a limiting factor in increasing the amount of livestock in the region. The purpose of the study is to monitor underground water sources in the West Kazakhstan region of the Republic of Kazakhstan to assess the zonality of their placement. The boundaries of natural and climatic zones on the territory of the region were laid over the publicly available cartographic materials on the hydrological data of the distribution of groundwater. The water source monitoring was carried out by examining their actual condition in specific geographical locations, including using remote sensing methods, with a further determination of quantitative and qualitative parameters. The paper considers the state and problems of water supply at the pastures in the natural and climatic zones of the West Kazakhstan region. The region is characterized by the use of groundwater in the water supply of pasture lands. Underground springs have a certain zonality in their location, manifest themselves at different depths corresponding to different geological horizons, and differ in a wide variation of water mineralization. In the dry steppe zone, it is recommended to use the aquiferous mid-upper quaternary alluvial, aquiferous upper Pliocene Akchagyl, and aquiferous upper cretaceous Maastricht horizons. The water sources used have depths of up to 120 meters, and the mineralization varies from 0.2 to 9.1 g/dm3. In the semi-desert zone, the upper-quaternary aquiferous marine Khvalynsky and the lower-middle-quaternary aquiferous marine Baku-Khazar horizons are recommended. The water sources used have depths of up to 90 meters, and the mineralization varies from 0.2 to 11.8 g/dm3. The semi-desert zone is characterized by the use of springs with depths up to 80 meters. The mineralization of water in the permeable modern Aeolian horizon is more often low (0.11–0.9 g/dm3) and rarely brackish (1.1–9.36 g/dm3).
