LANDSCAPE-GEOCHEMICAL BASIS OF DESIGNING THE ECOLOGICAL NETWORK OF AGROLANDSCAPES (CASE STUDY OF A MIDDLE TAIGA LANDSCAPE IN THE ARKHANGELSK OBLAST)
Abstract
Buffer zones within an agrolandscape are designed to isolate the vulnerable objects from undesirable or excessive matter flows, thus becoming mandatory elements of the ecological network. Our hypothesis is that under a certain spatial structure of catena and a certain critical width of a buffer zone the accumulative elements of catena will not be exposed to the polluting lateral flows from cultivated lands. The hypothesis was tested within a cultivated area of the middle taiga landscape in the southern part of the Arkhangelsk oblast. The trends of spatial distribution and migration of chemical elements in the taiga landscape were revealed. Location of the buffer elements of the ecological network for the protection of water bodies and floodplains against the chemical pollution was suggested with particular account of the different types of landscape neighborhood. The deluvial fans along the valley footslopes favor the deposition of the major part of matter washed away from the cultivated steep slopes. The terrace footslopes need an effective biogeochemical barrier which could be provided by tall grass meadows dominated by Filipendula ulmaria. The ecological network should be enforced in the deeply incised gullies with steep slopes
