Climate change and changing landscape a comparative evaluation on Chinese and Hungarian sample areas

Abstract

The effects of globalisation are becoming obvious not only in the world economy but in natural processes as well. Increase of deterioration of natural conditions result in more and more decrease of land and water resources. Some experts even suggest that the changing climate of the next several decades can result in the transformation of the natural landscape. Human activities, global and regional changes of climate and land use destroy the ecological environment, which also make the service function of the local ecosystem damaged constantly. We can improve ecological security of an area through regional land use pattern opti-mizing. The physical geographical consequences of aridification might be described through the decrease of ground water level, the change of the biomass quantity and quality. Their spatial and temporal variation may reflect the intensity and strength of degradation. Remote sensing is one of the best tools to follow these processes, applying different databases. Spatial analysis of the gained information may help us to delineate the areas potentially endangered by even a minor climate change.
