complexity, landscape, fluctuation, evolution, synoptic analysis, river landscape

The rapid acceleration of global changes in all spheres of human life requires implementation of holistic, integrative approaches. The aim of this paper is to outline the main ideas concerning the complexity theory in general as well as in landscape investigation. A system is said to be complex when the whole cannot be fully understood by analysing its components. Such systems usually do not move in a continuous and linear progression from the simpler to the more complex type, but they leap by the sudden emergence of successive levels of organization, towards strange attractors. The evolution of any landscape, as complex, open and self-organized system, can be explained by using synoptic analysis, where the global laws are considered in their geographical and temporal context. This approach is applied here to the problem of land cover evolution of the riverine landscape in the suburban area of Bratislava. Generally, the landcape of a river reach as an inundation area represents a space of conflicts between urban development and the flood regime of a large river. We recognized ten land cover categories of floodplain. The evolution of the area (1949-2004) can be divided into three evolutionary phases-fluctuations and we identified nine types of initiators/attractors. The modern evolution of the land cover pattern in the study area resulted in changes of geo-and biodiversity and increase of the landscape complexity.

CORINE land cover, land cover change, computer aided visual interpretation, statistical data, Slovakia

The paper brings the results of a synoptic analysis and assessment of land cover changes in Slovakia in the period 1970-1990-2000 by application CORINE land cover data layers: CLC70, CLC90 and CLC2000, derived by application of visual interpretation and computer aided visual interpretation of LANDSAT MSS, TM and ETM images. The relationship between the CLC data and the national statistics is also analysed. In the 1970-1990 period, a total 315,600 ha of land cover changed in Slovakia with the most intensive changes observed in the agricultural landscape. The changes that took place in the 1990-2000 decade were less extensive: 207,006 ha of land cover changes (with pronounced changes in forest landscape). Land cover data and the corresponding changes in Slovakia identified under CLC projects are characterized, apart from spatial precision, by compatibility and comparability at the European level.

sustainable development, protected areas, regional development, landscape connectivity, Tatra region

The mission of protected areas is to protect and conserve the most valuable parts of the landscape. The aim of the paper is to identify and analyse the context between the structure of the protected areas system and sustainable development protected areas dimensions (landscape/environmental, social/economic, institutional/manage-rial) in the area studied via selected criteria and indicators. Both – protected areas system and sustainable development concept have their own parameters, qualities, structure, dimensions and they are mutually overlapping in many different aspects. While protected areas are sets of material units with high natural and environmental value which is more or less strictly defined, sustainable development is a partly virtual system of concepts based on various sometimes ambiguous aims and priorities.

quality of life, intra-urban structure, urban change, Bratislava

Central to the interest in quality of life (QOL) in this paper is research into the relationship between people and their everyday urban environments. The paper explains the geographical approach to research into urban quality of life in the city of Bratislava. Two exemplar case studies are employed to illustrate the application of the multidimensional geographical perspective in a changing real urban context. The first case study analyses the situation in the 1980s, while the second one concentrates on living conditions in the city at the beginning of 21st century. This study shows that in spite of some similarities there has been some shift in the quality of life in the intra-urban structure of Bratislava since 1980.

population age structure, ageing from top, ageing from bottom, districts of the Slovak Republic, cluster analysis, hexagonal diagram

The population ageing process comprises the changes of age structure, which are indicated by the decrease in the number and proportion of children in the population and increase in the number and proportion of the higher age population categories. The main aim of the article is to analyse the time and regional aspects of population ageing in the Slovak Republic. The changes of the population age structure in Slovakia over time are evaluated in the years 1900-2005. Regional analysis of this process is oriented to the population ageing in Slovak districts. Using the 2001 census data the regional types of ageing structure are identified by cluster analysis. The relative ageing intensity in Slovak districts between the 1991 and 2001 census is presented by using a hexagonal diagram.

postsocialism, urban dynamics, morphological structure, functional structure, Slovakia

Post-socialist urban development in the case study of the Slovakia’s capital city is considered from an integrating generalizing perspective. The purpose of this paper is to propose a descriptive model of the spatiotemporally differentiated urban change, a potential base for further research. Such a model should have the ability to reflect a complex network of interdependencies between various wide and narrow partial processes discussed in literature. A cyclic expression of the urban dynamics linking its elements in the urban social and material environment serves as a basis for identification of a hypothetical footprint typology. In the scheme, the footprints of the most visible processes are connected to actual morphological types and sub-periods of transition. An exact testing of the spatiotemporal hypothesis is left in this paper for later stages of research.
