Popis: The relevance is related to the priority of protection of agricultural land, among which the most important are the especially valuable productive agricultural lands. They are a unique natural phenomenon from scientific and practical point of view, but they are evaluated very formalized. Land properties of this status are considered in geoecological coordinates. The aim of the research is to study the cadastral and geoecological properties of especially valuable productive agricultural lands, their statistical analysis for further land monitoring and protection using the example of the Tomsk region. Objects: 1627 land sites of the Tomsk region. Methods: analytical, cartographic, correlation and regression analysis. Results. The maximum number of plots of the especially valuable productive agricultural lands is in Tomsk (559 pcs.) and Kozhevnikovo (546 pcs.) districts, the most developed in agricultural respect. The largest number of especially valuable productive agricultural lands of high-cost per hectare is concentrated near Krivosheino–Molchanovo and decreases to the west and south. The maximum average value of especially valuable productive agricultural lands cost is noted in Krivosheino and Parabel districts – 7470–8444 rubles/ha. The minimum values of the value of especially valuable productive agricultural land are typical for Kargasok (1105 rubles/ha), Bakchar (1497 rubles/ha) and Tomsk (1623 rubles/ha) districts. The influence of the type of permitted use on the value of especially valuable productive agricultural land and on its size was also revealed. Sections have a complex configuration in 38 % of cases. 22 % of the plots have a configuration that is close to the correct one. The smallest number of plots of especially valuable productive agricultural land is classified as irregular – 9 %. The more correct the shape of the plot, the higher its cost. The largest number of plots of especially valuable productive agricultural land (55 %) has a compactness coefficient value in the range of 1,0–1,5; only 5 % – a compactness coefficient equal to 1. Comparative analysis of the cost of especially valuable productive agricultural land located on plakor, terrace and in the floodplain of the river revealed that floodplain plots have a lower cost compared to plakor and terrace positions. Significant differences in the cost of a hectare were found between the land «Meadow» and «Arable Land». The influence of the type of land on the area of especially valuable productive agricultural land is significantly high. The presence of a road has a significant positive effect on the area of especially valuable productive agricultural land plots. The location relative to the locality also significantly positively affects the area of plots of particularly valuable productive agricultural land, but does not affect its value. There is a positive Spearman correlation coefficient between the area and fragmentation of the site, which indicates an increase in the probability of dividing the site with an increase in its area. The geographical coordinates of the site, expressed in degrees, have little effect on the value of particularly valuable productive agricultural land. There is a noticeable tendency to reduce the cost and area of land plots with increasing latitude in the direction from south to north. The distance from the land plot to regional or regional centers or large settlements does not affect its cost.
