Abstract

We consider the estimated stability classifications (model-classifications of the integrated stability assessment) to assess the potential stability of the terrestrial landscape to changes in the parameters of the natural regime (potential stability) based on the developed landscape potential stability index. At the first stage, assessment parameters and stability classes are introduced (I-minimum, II-below average, III-average, IV-above average, V-maximum). For each class, the left and right boundaries of the parameter change are specified. At the second stage, the indicators are normalized on all scales, taking into account the type of connection of the parameter with stability (direct, inverse) and the degree of linearity (nonlinearity) of the connection. At the third stage, the problem of choosing weights (priorities) for estimation is solved. At the fourth stage, the form of the integral indicator is introduced (the sum of the normalized values of the characteristics taken with their weight). The estimated scale of the integral indicator is calculated based on the totality of all characteristics. At the final stage, the approbation of the approach is considered using the example of calculating the integral indicators of potential stability for several different landscapes. The role of the number of initial parameters and their weight in the calculations of integral stability indicators is revealed. A stability assessment is carried out for 5 landscapes of the territory of Russia, using the example of the Novgorod region (Priilmenskaya lowland), the Republic of Bashkortostan, the Ufa Plateau, the Lembolovskaya Upland of the Leningrad Region, and the Arctic landscapes of Franz Josef Land. The Arctic landscapes are the most unstable in terms of the integral stability index (class II, stability is below average), the remaining landscapes are assigned to classes III-IV (medium-stable - stability is above average), taking into account proximity to the left, right border of the class or its middle. The prospects for further research are outlined.
