Ecological-hydrological analysis of erosion processes on the key watersheds of Southern Ural steppe was used to determine
the surface runoff as a function of the physico-geographic and anthropogenic conditions, i.e., snow storage and soil moisture
reserves before winter, whose contribution reaches 68–81%. The rate of humus losses in chernozems and dark chestnut soils
was calculated for different periods in accordance with erosion stress and the extent of the economic development of the territory.
Agroecological types of arable lands with different surface runoff characteristics, rates of natural soil formation, and erosionrelated
soil losses are identified. Measures aimed to reduce humus losses in soils are proposed. Relationships between the rates of
soil formation and erosion losses are proposed to be used as ecological-hydrological criterion (index) of soil stability. 相似文献

This paper considers the impact of climatic factors on the forest fire rate in Ilmen State Reserve based on 66 years of direct observation data for 1948–2013. This period was marked by a gradual annual increase in the number of recorded fires in the reserve. The higher fire rate is generally related to lengthening of the fire season and more frequent fires in the spring and summer–early autumn periods. We did not obtain sufficient evidence to verify a relation of the higher fire rate to climate changes. The average monthly and seasonal weather conditions can be involved to explain only some causes of the interannual fire rate variability. The observed changes in some climatic characteristics could have contributed to an increase in the fire rate, while others could have reduced it. 相似文献

An analysis of geoinformation data on the spread of steppe fires is proposed, the areas of which are identified on the basis of a series of Landsat satellite images for 1984–2015. We selected five key sites located in different geographic areas of the Transvolga region and South Ural, covering clusters of the Orenburgskii state nature as well as adjacent agricultural areas. By analyzing the long-term dynamics, we determined a widespread trend of an intensification of steppe fires. Since the mid-1990s till the present, it has manifested itself in a significant increase in the area of occurrence and in recurrence frequency. It has been established that the cause for an intensification of fires in the steppe regions is a significant reduction in agricultural production, accompanied by restoration of vegetation cover on unused lands and accumulation of dry phytomass. It was determined that, given the favorable conditions for the occurrence of fires, the weather and climate factors increased in importance, implying a higher amplitude of fluctuations in the areas of the burnt-over areas, especially in abnormal years. Data on the current frequency of grass fires (both in protected areas and in a large part of agricultural lands) indicate that the vegetation cover and other components of steppe ecosystems are constantly in a state of post-pyrogenic succession. Using an example of one of the sites (the Burtinskaya steppe), a high restorative capacity of tree-shrub areas within the boundaries of the ecotopes occupied by them was revealed. It was noted that the absolute regime of reserve that excludes any economic activities, combined with an intensification of fire phenomena in the adjacent territories, gives rise to an acute fire-hazardous situation. It is pointed out that there is a need to establish a unified system for ecological monitoring of fires. 相似文献
