Development of three-dimensional models of the spread of pollution on agricultural land in industrial cities

Under conditions of excessive anthropogenic pressure on the environment special attention is paid to the ecological state of the soil in Kazakhstan. The quality of soil is the basis for production of environmentally friendly food products, which also provides a more complete transition to the organic use of land resources. The main sources of pollution are mining and metallurgical enterprises that pollute the environment with heavy metals and their compounds. In a light of the current requirements on sustainable development and transition to a circular economy, it’s necessary to create new models of "intelligent" agriculture, based on the use of automated management technologies, ecosystem modeling. The paper substantiates a method to the environmental assessment of agricultural land in industrial cities based on geoinformation modeling processes of the distribution pollutants in the urban environment. The proposed approach will provide a detailed and objective assessment of the environmental situation and will be the basis for the development of various recommendations for protection and rational use of land, including the development of a number of measures to clean up soil and reduce content of pollutants in soil, plants through introduction of a phytoremeditation system, use of natural bentonite clays and other minerals.
