landscape potencial, prediction, DTM, GIS, radiance, plant communities, secondary succession, Devínska Kobyla

This work focuses on evaluating the potential for the preservation of the xerotherm vegetation communities in the National Natural Reserve area on Devínska Kobyla. It is important to understand the topoclimatic differences of thermal and hygric characteristics with regard to this relationship. In this work, we use me-thods of quantitative planar estimations of the topoclimatic characteristics, calculations of insolation dynamics from a digital terrain model (DTM). The final evaluation includes geomorphometric fields – elevation and the derived characteristics. A model that quantifies the potential for xerotherm vegetation preservation was created. The model is based on analysis of the relationship between various types of quantitatively defined geoecological subjects and dynamics of vegetation change which were derived from a chronological sequence of aerial photographs. This model can be considered a definitive product of the research ready to be employed in the management of this valuable site.

car ownership, daily mobility, Poland, commuting

The purpose of the paper is to assess the interrelations between mass car ownership development, increase of daily spatial mobility and the potential spatial consequences of these phenomena in Poland in the period 1995-2005. There has been a purposeful selection of twelve county-level units, in which a survey has been conducted. The sample consisted of 1,372 respondents classified on purpose into car owners and non-owners. The respondents were asked to specify the distance, frequency and transport means, used in trips, associated with various forms of daily activity in the years 1995 and 2005. They were also asked about the vehicles they owned and their annual mileage. The analysis confirmed the existence of an interrelation between the development of car ownership and daily spatial mobility. It can also be indirectly assumed that in the case of the smaller centres the increase of the number of passenger cars was partly forced by the increasing mobility in the domain of job commuting. With respect to other forms of daily mobility (e.g. shopping) it was exactly car ownership that enabled extension of the length of trips undertaken. The overall increase of mobility in the period 1995-2005 was significant, but not immense. Concerning factors of the increase, the influence of changes of place of residence concerned mainly large centres (rapid suburbanization processes). In other towns key importance ought, instead, to be assigned to the change of trip destinations. Generally, the development of car ownership strengthened the regional and subregional centres at the cost of the local ones. This is most visible in the analysed towns of the broadly understood Western Poland.

environmental research, environmental geography, sustainability and quality of life, geography, Institute of Geography SAS

The article deals with the environmentally oriented research provided in the Slovak geography and landscape ecology with a special emphasis on the Institute of Geography SAS. Such kind of research started in Slovakia in mid 1970-ies and is related to names like Emil Mazúr, Ján Urbánek and Ján Drdoš. Step by step it has been developed as well as differentiated to several research streams: from theoretical studies, through the investigation of global, macro-regional, national, regional, and local environmental problems, following natural risks and hazards investigations, strategic environment assessment, environmental planning and policy to questions of perception and values of the environment as well as the understanding of the environmental quality as an important component of the sustainability and quality of life. Individual research streams as well as selected results are introduced in the article. Finally, the author thinks about perspectives of such kind of research at the Institute of Geography SAS.

quality of life, basic housing infrastructure

The aim of the article was to analyse territorial differences in the housing infrastructure as an indicator of quality of life and subsequently to set the analysis into the context of change of the quoted characteristics on the national levels in the interval between the two national censuses of 1991 and 2001, as well as to compare the relevant situation in Slovakia and in some neighbouring countries. This analysis is based on objective indicators of the basic housing infrastructure sorted out from the 2001 Census. Seven indicators were chosen: gas supply, water main, sewage, hot water, central heating, bathroom or shower, and flush toilet availability. Subsequently, the index of the basic housing infrastructure was computed for 72 territorial units. Cartograms contain the result. The basic housing infrastructure quality is higher in big cities, urbanized and industrialized districts in the western and north-western parts of the country. It is lower in the rural districts of the eastern and north-eastern parts.
