Разработка геоинформационной системы мониторинга воспроизводства населения России

Abstract

In the last decades of the XX–XXI centuries. in Russia, the nature of the formation of the population as a whole in the country and in its regions in particular has changed. During the post-Soviet period, the country is undergoing a deep demographic crisis, depopulation processes have been actively developed. In this regard, it becomes relevant to conduct a study on monitoring the reproduction of the Russian population. Monitoring based on geographic information systems has a number of advantages in processing and interpreting a large array of spatial data. The article shows the experience of creating a conceptual scheme of a geoinformation monitoring system, methods of geoinformation modeling, formation of the structure of a spatial database, a necessary element of geoinformation monitoring. The conceptual scheme of the geoinformation monitoring system is based on the development of a geoinformation modeling technique, the creation of a spatial data base and the formation of a geoinformation monitoring structure. The creation of a geoinformation monitoring system is supposed to be based on the Esri ArcGis Online platform, a database management system (DBMS)—PostgreSQL 10. The geoinformation modeling technique used in the work includes the creation of a spatial database, building models in geoinformation systems, and analyzing the results of geomodeling. For geomodeling and the subsequent creation of maps, a number of the most common methods and methods are used: typological, the method of cartographic anamorphic images, the method of qualitative and quantitative background, methods of areas, cartograms, ranges of values, the method of movement of arrows, etc. The spatial database is a subsystem for geoinformation monitoring of regional features of the reproduction of the Russian population and is designed to collect, organize, store and update data. The possibilities of geoinformation systems for monitoring the reproduction of the Russian population, methods and methods of modeling in geoinformation systems are considered. As a result, a database of spatial data “Reproduction of the population in Russia” was created and a series of spatio-temporal models was built. The trends in the reproduction of the population of the post-Soviet period are analyzed with the identification of the main periods in the transformation of the reproduction of the population, a typology of regions is carried out, taking into account the ratio of natural and migration growth and their contribution to the dynamics of the total population.
