摘要

The most important element of sustainable development in the Carpathian Basin is the rational use and conservation of soil resources and ecosystems (the geological strata-soil-water-biota-plant-near surface atmosphere continuum), maintaining their favourable "quality" and desirable multifunctionality. The natural conditions (climate, water, soil and biological resources) of the Carpathian Basin are generally favourable for rainfed biomass production (LANG et al., 1983; VARALLYAY et al, 1985). These conditions, however, show extremely high, irregular, consequently hardly predictable spatial and temporal variability, often extremes, and sensitively react to various natural or human-induced stresses. The main ecological constraints are: 1. Soil degradation processes. 2. Extreme moisture regime: simultaneous hazard of flood, waterlogging, over-moistening and drought sensitivity. 3. Unfavourable changes in the biogeochemical cycles of elements, especially of plant nutrients and environmental pollutants.
