Geoecological zoning of the Republic of Kazakhstan is given. 20 geo-ecological regions are highlighted, including the region 3 with the catastrophic level of environmental destabilization of the natural environment. The main factors of formation of geoecological conditions are natural (geological, climatic, hydrological) and technogenic (especially – industrial, oil, mining) factors. Environmental condition is characterized. Conservation of nature is justified. Considered the regions ecological risk of geosystems of Kazakhstan allow to identify the most important scientific and practical tasks in the field of optimization of natural environment specific natural-anthropogenic geosystems.

Kazakhstan

The environmental situation is becoming more and more important development affecting all spheres of political and economic prosperity of the state. In the third Millennium the world is changing at an increasingly rapid pace, and the joint action of States to protect the environment often lag behind economic and social change. Gradually, the economy of the countries-members of CIS penetrate the environmental standards of developed countries.

General characteristics of the territory

The area of Kazakhstan is 2 724 900 km2. The length from West to East is about 3000 km from the Caspian sea and lower reaches of the Volga to the Altai mountains and China, from North to South and 1700 km from the southern part of the West Siberian plain and the spurs of the Ural mountains to the Tien Shan and the Kyzyl Kum desert. The territory of Kazakhstan lies in the Central and southern latitudes of the temperate zone as far South it comes in a strip, crossing to the subtropics. The total length of the borders of the Republic is 12187 km, including: with the Russian Federation – 6467 km, Uzbekistan – 2300 km, with China – 1460 km, Kyrgyz Republic – 980 km, Turkmenistan – 380 km, on the Caspian sea – 600 km.

Geoecological zoning of the Republic of Kazakhstan

Geoecological zoning of the Republic of Kazakhstan allows to identify regions of the risk of danger of ecological destabilization of the environment, under the environmental risk should understand the likelihood of adverse consequences of any environmental resources (deliberate or accidental, gradual and catastrophic) of anthropogenic changes and factors. Identify areas of environmental risk classification is based on the signs of the degree of environmental stress environment.

Natural geological factors: tectonic faults, neotectonic movements, seismic and geodynamic activity play a large importance for geoecological assessment. Principles and methodology of an integrated geoecological estimation are universal, are applied in regions with the various natural and technogenic conditions, have great value for the environmental management [4–16]. On the territory of Kazakhstan are the following provinces geo-environmental catastrophic and critical levels of interference with the ecological state of the environment [1–3].

The areas with the catastrophic level of ecological destabilization of the environment

1. The waters and dried bottom of the Aral Sea (North Aral province).

The environmental condition. The death of the Aral Sea ecosystem. In 1990, the almost complete cessation of the inflow of river water, lowering of the reservoir 16 m, reducing the water surface area with 66,000 to 26,700 km, increasing the salinity of water from 10 to 46 g/dm3. The formation of a dried out bottom of sea salt desert dust-salt storms take out more than 1 million tons of salt per year.Excess indicators for all components of the environment; pollution of air, water and soil, destruction of biota. Mass human infection due to poor quality of drinking water or lack of it.

Measures for the protection of nature. Restoration of the Aral Sea as geosystems in the previous (1960) settings can not be, because it is the environmental changes become irreversible. This planetary ecological disaster. The solution is only possible on the basis of the International Programme for Saving the Aral Sea. It should be a comprehensive scientific study of the natural and built environment of the entire basin Syr Darya, Amu Darya and the Aral Sea region. The main objective – to stabilize at the present level of the Aral Sea, the division of the waters with the help of cutting the dams on the target reservoirs. Possible transfer of sea water from the Caspian Sea via water pipeline pumping stations; interbasin transfer of the runoff; interbasin transfer of the Ob river runoff in the Central Asian region on the basis of governmental agreements. Priority actions: strict regulation standards of water use and irrigation land drainage water and the increase in releases of river water into the Aral Sea.

In the provinces, as the geo-ecological systems are interconnected natural ingredients creates an opportunity to foresee and avoid or eliminate the adverse environmental impact of human activities [3]. This opens up the possibility of using these geo-environmental recommendations to support both current and future activities in the field of nature protection, allows to calculate the economic effect of environmental work, opens prospects for conservation and transformation of the nature of Kazakhstan.
