Solution of technological principles of complex analysis of the environment on the basis of GIS technologies and methods of mathematical modeling
The agricultural sector is one of the most important for the economy of Uzbekistan. Uzbekistan is the third largest exporter of cotton in the world. In the agricultural sector, 44 % of the population of the republic are involved. Active anthropogenic environmental impact in order to increase productivity in the agricultural sector was carried out without proper scientific justification. The increased demographic burden on the land has led to the intensification of desertification, salinization of land. Excessive application of chemical fertilizers into the soil, pollution of surface waters, which are often used for drinking and drinking water in rural areas, have led to an increase in the incidence of the population. The above problems indicate the need for a comprehensive analysis of the state of the environment in order to develop the most optimal ways to solve these problems. The paper gives examples of the development of regional zoning maps for various thematic areas. When zoning the territory, a mathematical apparatus developed by the famous mathematician Lotfi A. Zadeh was used. The theory of fuzzy sets makes it possible, on the one hand, to take into account the experience and intuition of researchers in the model, and on the other hand, to find a compromise between the increasing complexity of environmental processes and the requirements for the accuracy of research results. These approaches were used for scoring in solving assigned tasks. In a comprehensive analysis of the state of the environment, the OVERLAY procedure was used. It made it possible to develop an integrated map taking into account the contribution of each of the analyzed thematic areas in accordance with the tasks being solved. The solution of the technological problems of a comprehensive analysis of the territory will contribute to the development of a strategy for the environmentally sustainable socio-economic development of the republic.
