| Popis: | When referring to environmental diversity, the components (the variety of ecological systems and species, the genetic diversity, and the heterogeneity of anthropized and anthropic systems) vary at different spatial scales. This study proposes a method for assessing the latter component, based on a correlation between its spatial levels and the territorial statistical units. Consequently, Shannon-Wiener's informational entropy index, its associated measure of evenness, and Simpson's measure of dominance are used to characterize three components of the ethno-cultural diversity in Romania: ethnic, religious, and territorial. The results indicate that the three components exhibit lower values than natural systems, suggesting the possibility of assimilating them to young systems, and display a heterogeneous spatial distribution varying in time and across components influenced by administrative and political changes, which seem to control anthropic systems. |
