The environmental state of lands in the Sargatskiy municipal district of Omsk region

The article deals with some results of the environmental condition of lands in the Sargatka municipal district, located in the central part of Omsk region in the northern forest-steppe zone. The total land area of 373.1 thou ha, including agricultural land - 273.2 thou ha. The soil cover consists of ordinary black earth 44.7 % of the arable land, black earth-meadow - 20.9 %, meadow-black earth - 13.2 %, dark-gray forest soil - 11.0 % and meadow-black earth solonets - 10.2 %. The area of land with a high humus content is 61 997 ha, with an average one - 30 700 ha; with a low one - 8322 ha and 4291 ha have the very low of the one. It was established that in the territory dominated agrolandscape in transition stage of development, constituting 45.1 %, then - the mature ones - 44.7 % and the intensively formed ones - 10.2 % of the arable land. The intensive emerging agrolandscapes and the being in the transition stage of development ones pose a threat risk to agricultural use in mind shows of varying degrees of negative both natural and anthropogenic processes. As a result, we observe the weak environmental tensions in the land area of 24.75 %, the average one - 31.4 % and the strong one - 43.85 %. As a result of that observation were also identified the ecological and economic zones reflecting the degree of suitability of kinds of land for agricultural use. Among them are: the lands suitable for intensive agricultural use without restrictions - 58.67 thou ha; limited suitable for arable land and forage land - 74.41 thou ha; suitable for arable land and grasslands after the improvement - respectively 10.66 thou ha and 93.272 thou ha. The system analysis of the ecological state with using of the ecological stability coefficient and the coefficient of anthropogenic load shows that the area of land is labile stable, due to the high level of plowing and the large forested area. The value of the anthropogenic load coefficient corresponds to the increased anthropogenic load. The author of the article has proposed measures for the recovery of the productive forces of land to improve the ecological situation in the district territory.
