Landscape-Geophysical Foundations for Geosystem Monitoring of the Environment

The hydroclimatic block of regional landscape connections is represented by a fairly complex information model. The low representativeness of the known atmospheric humidity factors for ecological-geographical analysis of local natural complexes has been shown. A new geophysical parameter has been introduced, the edaphic humidity factor, which more accurately represents the diversity of states of topo-ecosystems and their mixed response to background climatic signals. The method of calculation of this factor has also been introduced. It was possible to significantly expand the methodological basis for assessing the ratios of heat and moisture, which made it possible to use this criterion much more efficiently to identify the local diversity of hydrothermal structures of ecosystems both for their initial state and at all stages of the forecast. The edaphic moisture coefficient characterizes a fairly wide variety of the initial states of forest hydro-edaphotopes and the trajectories of their response to background climatic changes. This confirms the fundamental possibility of predicting functional changes in topo-ecosystems under the influence of climatic signals through hydro-edaphotopes as a leading transmission link. The dynamics of forest ecosystems of the Volga River basin have been predicted based on changes in their hydro-edaphotopes under the expected global warming (according to the global climate prediction model HadCM3).
