    Opis:
    Problems of the retention capacity of the landscape and related runoff conditions are at present, at the time of the occurrence of frequent storm floods, a topical problem. Our research was aimed at the evaluation of effects of physical-geographical factors on hydrological conditions of the Fryšávka River drainage area occurring in the southern part of the Žďárské vrchy CHKO (Žďárské Hills Protected Landscape Area) depending on the current position of the landscape cover. Preparation and analyses of source data were carried out in ArcGIS 9.2 in the ArcView software product by means of the set of integrated software applications ArcMap, ArcCatalog and ArcToolbox. To determine hydrological conditions at the absence of hydrometric observations a method was used of numbers of runoff curves CN in a modification of the DesQ-MAXQ deterministic episode model. Based on hydrological characteristics, potential retention was monitored as well as the volume of flood wave, concentration time and peak discharge. Hydrological modelling was carried out on a design storm precipitation with the return period of 100 years. The significance of physical-geographical factors affecting the landscape retention capacity and runoff conditions was quantified by the statistical method of multiple regression and correlation analysis on the set of 95 partial drainage areas of the studied region. The analyses were carried out using the UNISTAT system. The method makes possible to select independent variables by gradual steps from most important down to least important. Finally, using the step linear regression, a certain number of independent variables was selected mostly affecting the size of a respective dependent variable together with the quantification of their operation through regression coefficients. Results achieved could be used at the implementation of preventive measures resulting in increasing the retention capacity of partial drainage areas, which served for the registration of major runoffs from a unit area.

    Opis:
    This paper examines the changes in stocks of water in clay soils against precipitation and changes in the groundwater table. The study was conducted during the summer period (May-September) in 2001 and 2002. According to the Kaczorowska` s criteria (1962) the year 2001 was very wet, and the 2002 – average. In 2001, ground water table was at a depth of 0 to 190 cm below ground surface level, and in 2002, from 50 cm to 150 cm below the surface. Water storages in the root zone (0-35 cm) developed in 2001 at the level of 100 to 125 mm, in 2002, from 88 mm to 122 mm.

    Opis:
    A comparative analysis, using the classification tree method, of typically agritourism and agriculturally inactive farms has been conducted in this paper. An interview questionnaire, carried out on 78 farms, has been applied as a research tool.According to the research, typically agritourism farms evaluated the quality of their own services more positively. However, these factors did not influence the improvement of offer standards. Perhaps they had to invest more often in the development of farms rather than focus on improving the sanitary and hygiene infrastructure. The residential buildings may have not been adapted to undergo redevelopment in that respect. Agriculturally inactive households rarely broadened their knowledge in order to improve accommodation conditions. They had higher standards regardless of the level of hosts' qualifications. Presumably, hosts who focus mainly on agritourism are more likely to improve accommodation conditions. They basically do not have to pay expenses that would be incurred by agricultural activity. The application of the classification tree method has allowed to observe that high self-evaluation of services provided does not always have to result in better sanitary equipment of rooms or possession of living rooms. The method has made it possible to present the examined factors in a simple graphical manner, thus allowing to notice differences between typically agritourism farms and agriculturally inactive farms.
