Comparison of two areas with different level of intensity of agricultural exploitation as concerns the ecosystem services
 KUNT, Lukáš
The aim of this thesis is to evaluate two localities with different intensity of agricultural use in terms of ecosystem services provided by nature habitats. In connection with the evaluation of the sites is in the works documented incidence size seminatural habitats, natural calculated value of the studied area using Biotope Vaulation Method (Seják et al., 2003) Application MapoMat developed by the Agency for Nature Conservation and Landscape. The value of ecosystem services is determined through expert analysis by replacement cost. There were differences in the value of ecosystem services important habitats between conventional and organic farming at localities 1 and 4. Natural habitat value conventionally used the site has a 2.53 milKč compared to the organic farming locality where the value was estimated at 194.6 milKč, In this context that the value of ecosystem services locations 1 shows a value of 4438.96 milesCZKyear-1 compared to location 4, calling shows a value of 7905.01 milesCZKyear-1. On this basis, were statistically significant differences in both localities in terms of the frequency of diversity factors examined specimens of ground beetles are examined diversity index P <0001.

Impact of the intensive agriculture on the ecological functions of the landscape
 MACH, Michal
This aim of this thesis was to compare the value of ecological functions of two areas with different intensity of the agricultural management. The expert methods of Seják et al. (2003, 2010) were used for the calculation of the ecological value of the area and of the value of ecosystem services. The BVM (Biotope Valuation Method) was used for the calculation of the ecological value. The Replacement Cost method was used for the calculation of the value of ecosystem services. The following services were evaluated: the flood-protective, production of the above-ground biomass, retention of the nutrients, support of biodiversity, production of oxygen, climatical service, and support of small water cycle. The rate of tillage was used as the indicator of the intensity of the agricultural management (25 % for the area I and 83 % for the area II), which corresponded to the proportion of natural biotops (60 biotops with total area of 108 ha in area I and 35 biotops with total area of 34 ha in area II).
