GIS BASED MODEL OF QUOTAS REGULATION AND ITS IMPACT ON THE EXTRACTION OF ECOSYSTEMS’ NATURAL RESOURCES AND SOCIAL WELFARE

Abstract

Research goals and objectives: to study ecosystem using GIS based technology to develop valid recommendations forsand extraction from water body. Object of research: ecosystem with natural resources. Subject of research: GIS Based Model of Quotas Regulation and its Impact on the Extraction of Ecosystems’ Natural Resources and Social Welfare. Research methods: optimization methods, GIS methods, differential-equations method, marginal benefit-cost analysis. Results of the research: An example of mathematical model for determining of ecological equilibrium during sand extracting in the ecosystem is developed using Google Maps. The influence of economic activity due to sand extraction on fish fauna is described. The GIS based ecological-economic model is developed on the logistic model basis for establishing regional quotas for extraction of natural resources during economic activity in the South of Ukraine. Regulatory economic mechanism of natural environment is proposed. It implies such quota for sand extraction from water body, which does not lead to deterioration of the quality of the nature environment and stimulate of social welfare’s increasing.
