In the context of increasing anthropogenic influence, there is an increasing need for continuous monitoring of land conditions and the development of effective measures for their rational use. To study the state of land in the Astrakhan region, an analysis of the land use structure was carried out,objectively reflecting the current state of industrial, agricultural and other impacts on land. In the region, a system of factors was formed that consider this problem from various aspects. At the same time, it became necessary to create an integral criterion that includes the entire set of local factors with their weight coefficients. The article presents formulas for determining the optimal weight coefficient of the first (most significant) factor, as well as all other criteria. The obtained requirements for the weight coefficients of the relevant factors should be provided in practice with sets of appropriate measures to improve the geoecological situation in the Astrakhan region. For clarity, an example is given that presents a set of factors for assessing the geoecological situation in the region. The factors presented were numbered in descending order of significance and divided into several groups. Based on the results obtained, a map of the integrated land use assessment indicator was compiled, which shows the actual geo-ecological situation for administrative areas. In conclusion, a number of recommended measures are proposed to be carried out to improve the current environmental situation on agricultural lands in the Astrakhan region.
