Mathematical modeling of processes in atmosphere and hydrosphere

Landscape genesis is totality of a transformations assayed by a geographical system from rise until supersede it other geosystem, as well as landscape genesis is historical process of a Earth landscape geosphere evolution, process of development all a diversity of species, genus, groups, types and other subdivisions of landscapes. Both these of aspect of disclose of earth landscape geosphere transformation we mast study in unity and interconditionality. The examined aria limits by plain section of walleyes of Amudaria in west, Syrdaria in east, Zeravshan in south and Aral Sea in a north. On the basis of our perennial aerospace and terrestrial researches of processes landscape genesis, dimensions on landscape maps made on miscellaneous terms, confrontation of maps and the constructions on them of matrixes of the areas of transitions between geosystems with miscellaneous ecological modes (hydromorphic, hygromorphic, mesomorphic, halomorphic, xeromorphic, anthropogenic) for the season 1950-2000 years were designed by us spatial balance models landscape genesis of investigated region. The modelling was made for different test area of region (delta of Amu Darya, Cis-Aral region, Kizil Kum, Golodnaya steppe), and then for plains of Interstream area of Middle Asia as a whole. The analysis of the built models results in a conclusion that landscape genesis on Interstream area of Middle Asia in the season 1950-2000 years in a general view showed as replacement hydro-, hygro- and mesomorphic geosystems of a halo- and xeromorphic, that characterizes him as a progressing anthropogenic desertification.
