STATISTICAL ANALYSIS AND INTERPRETATION OF THE HYPSOMETRIC UNIFORMITY (NON-UNIFORMITY) FOR THE REALIZATION OF THE GEOSPHERE MODEL OF STABILITY OF GEOSYSTEMS IN DAGHESTAN

Aim. In order to introduce the geosphere sustainability model of geosystems in the territory of the Republic of Dagestan, we conducted a statistical analysis and interpretation using a hypsometric analysis of the territory based on a detailed study of the relief morphology using mathematical statistics and visualization methods.

Methods. The morphological structure of the territory is determined using the method of planimetry at given intervals of heights according to a hypsometric map to a scale of 1: 1,000,000; morphometric analysis of the territory was carried out using a greater number of altitudinal gradations at predetermined border intervals above 500 m of height; hypsometric map was visualized using MapInfo Pro GIS.

Results and discussion. As a result of the research, it was revealed that the main argument regarding which the energy indicators of the productivity and stability of geosystems are transformed is the relief in its hypsometric characteristics. The numerical values of the variance of the variability confirm the significant hypsometric non-uniformity of the territory. Comparing the obtained results, we conclude that the maximum uniformity (minimum of diversity) is achieved when the entire area belongs to one height gradation, therefore, , and the minimum uniformity (maximum of diversity) corresponds to the uniformity index 1 , that is, when the areas occupied by all gradations of heights are equal, the value is . From this it follows that the hypsometric diversity (non-uniformity) of the territory of Dagestan is close to the maximum value.

Conclusion. The findings of the study were used to implement the previously proposed energy model and the stability of geosystems in the preparation of ecological certificate in a number of districts of Dagestan, since the obtained quantitative estimates of the territory hypsometry are necessary as background indicators for the energy projects being developed and stability limits of the geosystems of particular regions and the entire republic.
