Abstract
The purpose of the study is the spatial analysis of the factors of floodplain ecosystems and the calculation of rational use, through the calculation of technical and economic indicators and the calculation of the economic efficiency of haymaking. The assessment of the economic efficiency of the forage base was obtained based on the study of the grass stand and productivity of hayfields in five key areas of the Ob River floodplain, the study of soil properties, their qualitative characteristics necessary for understanding the soil fertility of floodplain ecosystems, on which land productivity depends. The spatial analysis of the rational use of the floodplain ecosystems of the Ob River was made in a semi-automatic way by decoding the Bing satellite image (the SAS Planet mapping and navigation program) in the Semi-Automatic Classification Plugin module in the QGIS geographic information system, the cartographic material was edited in the MapInfo Professional geographic information system.

The territory of the Khanty-Mansi Autonomous region-Yugra, according to natural and climatic characteristics, belongs to the zone of risky agriculture, this condition creates a low threshold for food security of the district, according to agricultural zoning, the territory belongs to the zone of animal husbandry, this is facilitated by natural conditions, in particular, the floodplain of the Ob River is a "storehouse of fertility", meadows with high productivity are formed here [1, 2]
Summary
The rational use of natural and land resources in the northern territories is complicated by special climatic conditions. The territory of the Khanty-Mansi Autonomous region-Yugra, according to natural and climatic characteristics (located in the taiga zone of the West Siberian Plain), belongs to the zone of risky agriculture, this condition creates a low threshold for food security of the district, according to agricultural zoning, the territory belongs to the zone of animal husbandry, this is facilitated by natural conditions, in particular, the floodplain of the Ob River is a "storehouse of fertility", meadows with high productivity are formed here [1, 2]. The possibility of rational use of floodplain ecosystems of the Ob River is realized through the approach of calculating the economic efficiency of the feed base. The increase in the volume of low-transportable high-quality crop and livestock products of local production partially ensures food security at the regional level. The Ob is based on the basic concepts related to land management, in particular, we operate with the terms forage land, forage base, and in geographical terms, a spatial analysis of the efficiency and rational use of floodplain ecosystems using GIS is made
