This paper presents the results of the 10-years observations for the restoration of soil-vegetation cover of oil polluted taiga landscapes of Western Siberia after remediation. The author analyses some indicators of physical and chemical composition, properties of soils, the changes in species composition and correlation of ecological and biomorphological groups of species, and evaluates the changes in plant community methods of ecological bioindication. There has been revealed the influence on the direction of successional changes in environmental factors such as the situation in the macro-and-mesorelief, properties of soil and the composition of the original vegetation. There is an active oil-and-salt spread of contaminants in the soil adjacent parcels and their progressive eutrophication.
The present research considers the problem of covering a
graph with minimal number of trails satisfying the pre-defined local
restrictions. The research is
devoted to the problem of graph covering by minimal number of trails satisfying
some local restrictions. Algotithm of allowed Eulerian cycle construction is
considered. The authors showed that it is possible to
recognize the system of transitions and solve the problem of constructing the
allowable path by linear time. It’s also possible to find allowable Eulerian
cycle for Eulerian graph or to proclaim that such a cycle does not exist by the
time O(｜V(G)｜.｜E(G)｜). All presented algorithms have the software realization.
