Basics of the Erosion-hydrological Process Management on Sloping Lands by Formation of Soil Protection Systems of Adaptive Landscape Agriculture
摘要
The subject of this overview and analysis is the result of our own long-term research (over 60 years) and literature data substantiating the conceptual directions, ways, and principles, theoretical and practical provisions for elaborating a highly effective erosion-hydrological process management systems providing erosion-controlled land reclamation. The objective of the study was to develop scientific foundations for the erosion-hydrological process management system based on the adaptive landscape principle of agriculture. The methodological basis of our research was a system of methods used in soil-control land reclamation, soil science, agriculture, hydrology, and other related sciences. Our research was mostly based on the use of the runoff plots. The objects of research were natural and anthropogenic factors of runoff formation in the agrolandscapes of the forest-steppe zone on gray forest soils (Orel region) and steppe zone on ordinary chernozems (Samara region), and light chestnut soils (Volgograd region). It has been found that soil erosion control should be based on the landscape principle of regulating the hydrological regime of the territory and creating systems of adaptive landscape farming. The analysis of theoretical foundations of erosion-hydrological process has allowed us to define the general direction of search for new ways and approaches to solve the problem of soil erosion control and the development of fundamentally new effective anti-erosion techniques and measures, a new approach to assess their role, and the creation of highly effective environmental management systems. The scope of the results is the creation of an erosion-hydrological process management system based on adaptive landscape farming in vast territories of the forest-steppe and steppe zones of the European part of the Russian Federation. When creating erosion-hydrological process management systems on an adaptive landscape basis, it is necessary to rely on the knowledge on formation of landforms and upper parts of sediments, the theory of interaction of meltwater with frozen soil, the law of the limiting runoff factors, and the concept of ice screen formation.
