ASSESSMENT OF THE BLACK SEA SHELF ECOSYSTEM SUSTAINABILITY WITH MATHEMATICAL SIMULATION METHOD
The system analysis approach has been used for assessment of the sustainability of the marine shelf ecosystem with the method of mathematical modeling on the example of the north-western shelf of the Black Sea, as the most vulnerable part of the sea to the influence of natural and anthropogenic factors. Based on numerical experiments, an analysis of ecosystem risk in dynamic phase space was performed. Results have shown that the ecosystem risk of the Black Sea shelf zone has fluctuated around baseline value over the last decade under the existing influences of natural and anthropogenic factors, but the system approaches an unstable state with an increase of the combined effects of natural and anthropogenic factors. Key-words: system analysis, ecosystem risk, marine ecosystem, mathematical modeling, ecosystem stability, Black Sea.
期刊介绍：
Geographia Technica is a journal devoted to the publication of all papers on all aspects of the use of technical and quantitative methods in geographical research. It aims at presenting its readers with the latest developments in G.I.S technology, mathematical methods applicable to any field of geography, territorial micro-scalar and laboratory experiments, and the latest developments induced by the measurement techniques to the geographical research. Geographia Technica is dedicated to all those who understand that nowadays every field of geography can only be described by specific numerical values, variables both oftime and space which require the sort of numerical analysis only possible with the aid of technical and quantitative methods offered by powerful computers and dedicated software. Our understanding of Geographia Technica expands the concept of technical methods applied to geography to its broadest sense and for that, papers of different interests such as: G.l.S, Spatial Analysis, Remote Sensing, Cartography or Geostatistics as well as papers which, by promoting the above mentioned directions bring a technical approach in the fields of hydrology, climatology, geomorphology, human geography territorial planning are more than welcomed provided they are of sufficient wide interest and relevance.
