The St. Petersburg State Polytechnic University analyzed the ecological diversity and state of recreational areas of St. Petersburg and the Leningrad Region on the coast and water area of the Gulf of Finland. Recreational loads, pollution sources, volume and composition of effluents, etc. were determined. The state of small rivers crossed by the Baltic pipeline system in the recreational area of St. Petersburg as sources of potential danger of water pollution by oil products is assessed. Data on the development of energy and fuel transportation system on the coast of the Gulf of Finland (ports, oil and coal terminals, energy facilities, etc.) and their impact on the environment are systematized. nd a comprehensive ecological assessment of the state of water areas in the zones of energy transportation flows requires processing and analysis of a large volume of information materials. For this purpose, information-analytical database (DB) "Recreational water use" is created. The database is relational, created on the basis of standard MS Office package in Access software environment and consists of a number of related tables (characteristics of recreational potential, anthropogenic loads, objects of fuel and energy complex, etc.) for assessment and forecasting of the state of recreational water areas.
