Regional Inequalities of Age Structure in the Light of Different Demographic Behaviour in the Czech Republic. – Geografie – Sborník ČGS, 104, 1, pp. 13 – 23 (1999). – The article deals with the influence of regionally different women’s fertility on the changing age structure of Czech districts in 1990s. Long term regional differences of the age structure and their consequences are analysed as well as differences of reproductive behaviour and new demographic trends under the recently changed social and economic conditions. The changing nature of some other demographic phenomena as induced abortions or illegitimate births is also discussed. As fertility rate and abortion rate have dramatically dropped since 1992, Czech Republic can now be treated as a developed European country in this respect; the share of children born out of wedlock remains relatively low so far. The current natality trends will soon result in ageing of population in all Czech regions.
Key words: age structure – total fertility rate – reproduction – regional differences. BLAŽEK Jiří:
Regional Development Theories: A Vicious Circle? – Geografie – Sborník ČGS, 104, 3, pp. 141 – 160 (1999). – The recent upsurge of interest in regional development issues in the Czech Republic is hindered by lack of understanding of the recent progress in regional development theories. This article provides a comparative analysis of the main theories. Several basic parameters are identified in each theory by means of which the regional development theories are classified into several groups and briefly discussed.
Key words: regional development theories – classification – critique. ČAPEK Richard, FORSTOVÁ Jana:
Analysis of the Distortion Characterization Q on the Basis of Eckert’s Projections. – Geografie – Sborník ČGS, 104, 4, pp. 243 – 256 (1999). – Distortion characterization Q is calculated as a ratio of the area with acceptable distortion in the map to the Earth surface. The sequence of 100 projections arranged by Q where area distortion limit is Kmax = 1,5 Kmin and angular distortion limit 2ωmax = 40°, was published by Čapek (1997). In this paper 25 different combinations of distortion limits are used for deriving Q. New 25 sequences of Eckert’s projections are analysed afterwards.
Key words: distortion – projection evaluation – Eckert’s projections. ČERMÁK Zdeněk:

This community of reemigrants began to return to their mother country in 1991 when also humanitarian aid programme was launched. The analysis is based on a questionnaire survey within the resettlers, experience and databases of state institutions and non-governmental organizations. How the resettlers adjust their lives to conditions in the Czech Republic and which factors influence most the migration/integration policies in the Czech Republic is formulated in the conclusion.
Key words: migration – Volhynian Czechs – integration – adaptation – multiculturalism. KAŇOK Jaromír:
Cartogram and Cartodiagram – Determination of Objective Scale. – Geografie – Sborník ČGS, 104, 4, pp. 268 – 281 (1999). – On thematic maps created on computers mistakes often appear, because specialists in informatics who lack the fundamental knowledge of thematic cartography usually make mistakes. One of the most frequent mistakes arises when creating scales of cartograms and cartodiagrams. Cartogram is a map with partial territorial units, to which statistical data (relative values) mostly of geographical character are illustrated by areaway. Cartodiagram is a map with partial territorial units, in which the statistic data (absolute values) mostly of the geographic character are demonstrated by diagrams. The following procedure should be kept: numeration of occurrence of the phenomenon in regular intervals; determination of the distribution; eventual testing; creation of scale according to the character of frequency division; choice of suitable colours, rasters; arranging of resulting cartograms or cartodiagram.
Key words: thematic cartography – cartogram – cartodiagram – scale – terminology. KOLEJKA Jaromír, LIPSKÝ Zdeněk:
Maps of present landscape. – Geografie – Sborník ČGS, 104, 3, pp. 161 – 175 (1999). – The landscape mapping and the landscape map compilation is relatively an indeveloped branch of the modern cartography. The multiparameter maps of natural and present landscapes are based on the analytic data integration and the systematic presentation. The two-layer maps of present landscape consist obligatorly both of the overlayed natural background map and land use map. Three examples of the map creation at different scales were discussed.
Key words: landscape mapping – geoecological maps – mapping methodology. KONEČNÝ Milan, VOŽENÍLEK Vít:
Trends in Cartography. – Geografie – Sborník ČGS, 104, 4, pp. 221 – 230 (1999). – The end of the 20th century is often labelled as the era of rapid development of information technologies. Nevertheless, maps still rank among chief and most important sources of land information. New technologies include the latest achievements of computer science and telecommunications and allow to link much attribute information to spatial data. New cartographical products emerge. The paper examines the main recent trends within cartography in this stage of development. All trends influence cartographical education, too.
Key words: cartography – distance mapping – GIS – cartographical education. KŘÍŽEK Marek:

Selected aspects of the ethnic border research. – Geografie – Sborník ČGS, 104, 1, pp. 1 – 12 (1999). – The article deals with the Czech/Polish ethnic border. All municipalities at the Czech/Polish transition zone have been examined in various years between 1804 and 1991. Each municipality has then been allocated to one of four categories. Results include a new delimitation of the Czech/Polish ethnic transition zone which underwent certain changes over the past 100 years in the Teschen region. It has developed from a relatively narrow strip in early 19th century into a broader area which covers almost whole of the ethnically mixed Teschen region.
Key words: ethnic border – Czech/Polish transition zone – nationality. STEHLÍK Jiří:
Modelling the subsurface flow component in the runoff recession phase by means of a linear and non-linear reservoir model. – Geografie – Sborník ČGS, 104, 3, pp. 176 – 187 (1999). – The paper deals with the time variability of the subsurface water storage depletion. The analysis was done for the small experimental basin in the Jizera Mts, Czech Republic. The research was focused on the hydrograph falling limbs – recession curves – which were selected from daily runoff series using various selection criteria. These criteria include a requirement that a curve should represent subsurface flow which is not augmented by surface runoff. The selected measured recession curves are modelled by means of the exponential and hyperbolical law of depletion. The time variability of the recession curves is quantified by the variability of the modelled recession parameters. 22 variables representing antecedent climate and runoff conditions as well as the conditions during the recession period were defined for the examination of possible causing factors of the recession curve time variability. The correlation analysis and the multivariate statistical methods were applied.
Key words: Recession curve – water storage – correlation analysis – multivariate statistics. VOŽENÍLEK Vít:
