Abstract


Until the present time the sufficient amount of the methods and ways of the estimation of the modern processes of morphogenesis has been used. Basically, all these methods are reduced to describe the morphometric features, the velocities of the displacement of debris down the slope, or, for some of them, the volume created by their forms. Even if we can have full quantitative features dynamic, it's not always possible using them, to compare the modern morphogenesis rates, even if made by same process. The modern exogenic processes matching is possible when one "universal" factor is used, which allows to fully value the morphogenesis efficiency and define its relationship with modern climatic change. This factor characterizes the following: the total volume of the material moved at the time of development of the process; the relief form, created as a result of its actions; the determination of the specific value of the volume material, transformed by process on unit area territory. Furthermore, this factor allows calculating the denudation rates in different natural complex, which are provided one or group of the processes, as well as will allow defining energy stability of the relief and its response on modern climatic change. At present, the use of the energy approach to describe denudation processes in geomorhosystem has not got the proper development. However, the development of the scientific interest to this direction gave significant impulse for development of these methodologies of the energy analysis. It is shown by concrete facts that measurement of energy efficiency of geomorphological processes in quantitative units - a Joule - allows to reveal not only the main point of this process, but also enables to compare it with any others. Such approach enables the matching of efficiency of the operating the genetically different systems, as well as change in their dynamics, connected with fluctuations of the energy amount entering into the system from the environment.
