Determining changes and flows in European landscapes 1990-2000 using CORINE land cover data

摘要

The CORINE land cover (CLC) data derived from satellite images for the period of the 1990s and 2000 (+/- one year) provide information about land cover changes for a substantial part of Europe. Availability of these data can contribute to new approaches to the assessment of the European landscape, for instance in the context of environmental and economic accounting, diversity, modelling of its properties, etc. These possibilities are given by the fact that land cover reflects the biophysical state of the real landscape. The paper contains information about frequency and areas of CLC and their changes in the period 1990-2000, but above all in the processes - flows (LCF) that take place in the European landscape. Results of statistical analysis and maps demonstrate the frequency and rate (by two values: one above and another below the mean LCF rates) of the following processes: urbanisation (LCF1), intensification of agriculture (LCF2), extensification of agriculture (LCF3), afforestation (LCF4), deforestation (LCF5) and construction of water bodies (LCF6). LCF1 was most conspicuous in the Netherlands (2.1% of total country's area), LCF2 in Ireland (3.3%), LCF3 in the Czech Republic (over 3.5%), LCF4 in Portugal (over 4%), LCF5 in Portugal (over 3.5%) and LCF6 in the Netherlands and Slovakia (over 0.1%). The overall area of identified land cover changes in 24 European countries in the period 1990-2000 was around 88,000 km super(2) which equals 2.5% of their total area. Details presented concerning the LCF frequency and rate will certainly contribute to the overall awareness and anticipation of possible developments in the European landscape.
