Anthropogenic impact on agricultural landscapes of the Akmola region of the Republic of Kazakhstan

The relevance of research topic is confirmed by the presence of environmental problems of steppe land use and the need for its rationalization. The article examines the issues of ecological stability of agrolandscapes of the steppe zone in agricultural circulation and determines environmental and economic damage that occurs when their functioning is disrupted.

The goal is to assess the degree of anthropogenic influence when using agricultural landscapes based on the example of the Akmola region.

The content of research topic determined the choice of the following methods: historical, logical, statistical, system analysis, graphic modeling.

Results - taking into account factors that destabilize the landscape-ecological balance, ecological zoning was carried out in the region, the degree of stability of steppe agricultural landscapes under anthropogenic influence was determined, based on  mathematical model of erosion process,  intensity of washout was calculated, environmental and economic losses arising in connection with violation were indicated, self-regulation of landscapes, environmental protection (antierosion) measures have been developed. The amount of residual flushing after they are carried out characterizes the effectiveness of reducing the water flows.

Conclusions - field agrolandscapes of agricultural enterprises of the Akmola region, specializing in production of crop products, can be classified as anthropogenically disturbed with low degree of environmental stability, which is due to the significant plowing of their territory. One of the main factors of environmental destabilization in steppe agricultural entities is the spread of water erosion on slope arable land, environmental damage from which is confirmed by the loss of soil layer. The proposed measures to support landscape environmental stability can be applied when planning the use of land resources and developing on-farm land management projects
