ТИПОЛОГИЧЕСКОЕ ГЕОМОРФОЛОГИЧЕСКОЕ РАЙОНИРОВАНИЕ ЗАПАДНО-СИБИРСКОЙ РАВНИНЫ
2015
The numerous geomorphologic regionalizations of the West-Siberian plain are based on different and often lax principles and have less in common. The authors suggest a new approach to typological regionalization using the k-means clustering of the space cells, which are small (20' x 30') in comparison with the whole territory. Each cell is characterized by a set of geomorphic, exodynamic, tectomc and physiographic parameters. Two sets including 9 and 14 parameters were used in this work and different numbers of clusters for each set were obtained. The resulting maps show the spatial differentiation of the West-Siberian plain in respect to given set of parameters: from the major features brought out by 2-3 clusters to detailed characteristics apparent at 10-12 clusters. The geomorphologic types thus obtained may be combined into hierarchical system by subsequent tree clustering.
