Posouzení změn erozního ohrožení pozemků v delším časovém horizontu
PICKA, Patrik
The diploma thesis on Comparison of erosion threat to land over a longer period of time aimed to assess and evaluate erosion in a defined time period, namely from 1938 to the current state. The area under consideration was the cadastral area of Kostelec located in the district of České Budějovice near Hluboká nad Vltavou. The work was divided into several parts. The first part was a literature review, in which we deal with the history of the social organization in the Czech Republic du-ring the period under study, we also deal with the issue of erosion and protection against it and last but not least with the land-use regulations. In the second part of the qualifying work we describe the site of interest and deal with the calculation of erosion shear in six periods, namely 1938, 1952, 1964, 1968, 1995 and the present. Soil loss was calculated using the USLE equation of Wischmeier and Smith (1978) and two see-ding practices were used. The first seeding practice was used for the earlier period namely 1938-196 and the second for 1995 and present. The results of the soil loss calculations were summarized and compared and then evaluated. The results showed that land consolidation and appropriate seeding techniques have the effect of reducing soil erosion shear and these practices should be considered. With this knowledge, erosion can be brought under control and to acceptable levels.

The causes and consequences of the farmland fragmentation
Janovská, Vratislava ; Sklenička, Petr (advisor) ; Karel, Karel (referee)
Fragmented ownership of agricultural land is currently a very actual topic in the Czech Republic but also abroad. The research studies were developed in collaboration with the research team at the Faculty of Environment Sciences, Department of Land Use and Improvement, led by Professor Petr Sklenička. This research is solving problems related to the impact of agricultural land use on the spatial structure of agricultural land, fragmentation, and homogenization. Scientific studies that are part of this doctoral thesis emerged progressively and are logically linked.
