Econetwork sustainability under desertification pressure in deltaic ecosystems of arid regionsN.Mamutov, P.Reymov, M.Reymov, V.Statov, Ya.Khudaybergenov Karakalpak State University Transformation of the deltaic and riparian ecosystems in the arid regions is a great challenge for the environment protection and biodiversity conservation. There is a set of impacts that causes tremendous changes in ecosystem functions, including anthropic pressure, desertification, soil erosion and drought.  To preserve vulnerable and unique plant communities and habitat for endangered species one need to manage land use with a especial emphasis to support existing econetwork. We mad an analysis of the main components of this econetwork for the Northern part of Amudarya delta and every part of the ecosytem could be presented as a separate compartment with specific edaphic parameters, spatial location and site-specific interaction with other components of the ecosystem. The model is compatible with satellite imaging after calculation of spectral indexes to correct input data. This model had been arranged as dynamic map with joined geoinformatic tools for spatial analysis and expert support. This conception develops idea of geoecologic map as a base for a spatial decision support system, combining snapshot of the ecosystem and a scheme of a feedback and interactions between part of the natural complex. The model can forecast changes in a spatial structure of the deltaic ecosystems for the various  climatic and watering scenarios.
