Dynamics of settlement and population of Anabar district: spatial analysis using GIS technologies

Abstract

The subject of the study is the location and population of the Anabar ulus in dynamics. The purpose of the study is to study the dynamics of the number and settlement of the population of the area under consideration using GIS technologies. The author conducted a study based on archival, statistical and cartographic sources. Verification of the reconstruction of the settlement network was carried out during field research in Anabarsky ulus in September 2020. The results of the work are presented by thematic layers in the GIS developed by the author, reflecting the dynamics of settlement from 1926 to 2020. The attribute tables contain data on the population, information about the location of settlements. В The novelty of the study consists in the reconstruction of the settlement of the population of the Anabar district from 1926-2020 on the basis of multi-time maps and census data. It is established that as a result of the policy of transferring the nomadic population to a sedentary lifestyle and the enlargement of farms carried out during the Soviet period, there was a decrease in the number of settlements, while an increase in the population of settlements is traced. The compiled maps demonstrate a decrease in the area of population settlement in the territory of the studied area. A number of research sources are being introduced into scientific circulation for the first time and are used in the analysis of the settlement and population of the studied area.
