The salt-dome landscape genesis: paradoxes of rational nature management

Abstract

The paper considers regional peculiarities of the use of natural resource potential of landscape geosystems formed in the course of halokinesis. Parameters of stability of salt-dome geosystems to anthropogenic influence resulting from the interaction of geodynamic processes and physical-geographical conditions are estimated. A method to evaluate the stability of landscape geosystems formed by salt-dome processes to anthropogenic transformation is offered. Accounting of volume of underground natural resources management connected, mainly, with salt rock extraction is significant. Excess of the total square of all forms of nature management under an area of the landscape geosystem formed by salt diapir, represented as the coefficient of nature management (CNM), acts as trigger risk. There are regularities of transforming the natural management structure in the regional models on the examples of basins: the Caspian-Cis-Urals, Trans-Carpathian, the Catalan, and Mexican. Within landscape geosystems having a salt-dome origin, the indicator of the coefficient of nature management can show as balanced geosystems, despite the development of subsurface resource management (Avery Island) or being in crisis geoecological situation (Iletskiy dome), so experienced anthropogenic catastrophes of different types (Jefferson Island, the Solotvinskiy dome). Principals of safe subsurface resource management and rational recreational-touristic use within salt structures of open kinds were developed.
