Zaimenko N. Scientific principles of structural-functional constraction of artificial biogeocoenogis (in the system Soil-Plant-Soil).

Object of research - the biogeocoenosis models for search of optimum management's mechanisms of physical, chemical and biological parameters of soil and the definition of ways of increase the efficiency of plants with different forms of life. Methods of research are: multivariable approach, system analysis, study of microbiological processes, quantitative estimation of parameters. This thesis dedicates to development of structural-functional basis for detailing of artificial biogeocoenosis and creating of closed cycle in biological systems using recovered materials. The whole of components of this cycle (soil substitutes with controled parameters, fertilizers with prolong activity, biologically active compounds and plants with different forms of life) were studied. Quantitative and qualitative criteria of fibrous soil substitutes were determined. The detailed analysis of physico-chamical, microbiological, ecologo- physiological, biochemical and biophysical processes in artificial ecosystems formation w as made. The features of growth and development of higher plants in the limits of artificially formed biogeocoenosis were studied under the conditions of simulated microgravity, weighlessness and in the hermetically sealed boxes. The mechanisms of their selfcontrol were determined. The system Soil-Plant-Soil was described in the meaning of dynamics of the surroundings and plants interaction. Information-resourse models were developed for finding the main principles of ecosystem formation. The application spheres are ecology, nature protection, space biotechnologies and training courses.
