The study of changes in the land fund balance to manage the sustainable spatial development of the developed and developing territories in Russia

Abstract

The analysis of changes in the land fund balance reflects the implementation of the scientific paradigm – “minimum initial information - maximum valid generalizations”. Active indicators, namely the shares of different types of land in the composition of certain land categories from the total area of a certain land category should be a priority. In 2011-2017, the share of settlement lands in the total land fund in the Russian Federation increased from 1.15% to 1.19%, industrial and other special-purpose lands - from 0.99% to 1.02%, which corresponds to modern Russian ideas about the spatial, but extensive, development of territories. The rate of change in the shares of different lands from the area of lands of different categories, %/year, is proposed to use an integrating estimated indicator for the spatial development of territories. The share of agricultural lands in the Russian Federation was increasing in the composition of settlement and industrial lands at a rate of 0.03%/year, which indicates their degradation. The share of forest lands decreased in the composition of industrial lands (-0.09%/ year). These lands served as a “source” of new farming lands for agricultural lands. In the settlement and industrial lands, the share of building land was increasing (0.06%/year), while the share of land under roads was decreasing (from -0.03 to -0.05%/year) due to their unbalanced development. Disturbed lands also need their intensive reclamation.

Application of the algorithm for calculating the boundaries of built-up areas from satellite images to calculating the areas of flooded land and the environmental potential of the territories of settlements

“…As the cornerstone of the work, a meaningful analysis of the seasonal decline in the value of the environmental potential (hereinafter-EFP) of the territory of the cities of Khabarovsk, Komsomolskon-Amur, Amursk, the villages of Troitskoye and Yelabuga, caused by periodic flooding of lands, was carried out. The principles and calculation algorithms for calculating the EFP were described earlier [5,6,10], the initial value of the regional specific EFP of the territory was taken as 800 points/m 2 ; the results are summarized in Tables 7 and 8.…”
