The effect of sand mining on model groups of organisms (vascluar plants, beetles, amphibians and birds) was studied in South Bohemia. The studies were made in the next biotopes by model area sand pit Roudná II southern from Planá nad Lužnicí: unforested area (after mining), forest (on recultivated plots and seminatural forest) and water biotopes (depressions after mining). The next characteristics of biodiversity were determined: the diversity of communites, the frequency of protected, rare and vulnerable species. The protected species occur mainly in amphibians and birds. The suitable recultivation measures were proposed on the base of biodiversity studies.

This diploma paper researches ecological damage and recultivations before and after 1990. It follows the legislation progress and the financial funding concerning this area, endowment policy and abroad approaches comparism. It is focused on distinct opinions relating to human caused environmental damage slicking. The operative part describes one of the largest middle Europe dump recultivation -- Radovesická dump.

Populiariausias atliekų valdymo metodas ne tik pasaulyje, bet ir Lietuvoje vis dar išlieka atliekų deponavimas sąvartynuose. Lietuvoje, 2009 metų duomenimis, sąvartynuose buvo pašalinta 90,6 % atliekų. Šiame darbe trumpai aptariama atliekų sąvartynų įrengimo, bei sąvartyno lauko uždengimo tvarka ir rekomendacijos. Aptariami keturiuose uždarytuose Kauno rajono sąvartynuose (Digrių, Gaižėnėlių, Miškinių ir Ilgakiemio) atlikti uždengiamojo sluoksnio būklės tyrimai. Remiantis gautais tyrimų duomenimis daromos išvados apie sąvartynų būklę. Gauti rezultatai rodo, jog ne visi sąvartynai rekultivuojami laikantis taisyklių ir rekomendacijų. Kadangi pastaraisiais dešimtmečiais labai susirūpinta švarios aplinkos išsaugojimu, ekologija ir aplinkos taršos mažinimu, aktualus klausimas išlieka tinkamas atliekų tvarkymas, sąvartynų tinklo optimizavimas (taip pat visiškas jų atsisakymas, dėl valstybių politikos kitaip tvarkyti atliekas, pavyzdžiui, jas deginant), Lietuvoje svarbus klausimas yra senų ir nebenaudojamų savartynų uždarymas. Reikia pasirinkti tinkamą sąvartyno uždarymo būdą, kadangi blogai rekultivuotas sąvartynas, gali sukelti didelę ekologinę katastrofą. / The most popular method of waste management not only in the world, but also in Lithuania, remains depositing waste in landfills. In Lithuania (according to the 2009 data) 90.6% of waste was deposited at the landfills. This work discusses the installation of the landfill, the procedures and recommendations of creating the final landfill covers. There was performed a research on four closed landfills in Kaunas district (Digriai, Gaižėnėliai, Miškiniai and Ilgakiemis) to find out the condition of landfill’s cover layer. According to the findings, conclusions about the condition of these landfills are made. The results show that not all landfills undergo recultivation in accordance with the rules and guidelines. Preservation of the clean environment, ecology and reduction of the environmental pollution is the major concern for the last decades and the most relevant question remains the proper waste management, optimization of the landfill network (as well as the complete abandonment of the landfills, because of different waste management policies, such as incineration). Still, Lithuania has to deal with old and disused landfills, so the proper way to close the landfill must be chosen, because poorly recultivated landfill can cause large ecological catastrophe.

This thesis is focused on natural elements in the microregion Bechynsko,it describes and localizes geohazards (ecological hazards) and natural risks, It designs solutions for elimination of this problems. Designed management of this area leads to sustainable development and it is outlined on the basis of the own SWOT anylyze. In the end of my work I prepared sample case studies which are focused on special geohazards and natural risks and I suggest suitable landscape management and its recultivation.

This thesis pursues amphibian biotop preferences in locations where moldavites were quarried in the past. Field work took place in two localities near Trhové Sviny. The first one is situated near the village of Slavče where an illegal extraction still occures,.The second locality is found by the village of Dobrkovská Lhotka. This locality was partially recultivated in 2010. The aim of this work was to establish which factors do influence different amphibian species in the both studied locations. There were found five various species of amphibians near the village of Slavče: the Common frog (Rana temporaria), the Edible frog (Pelophylax kl. esculentus), the European fire-bellied toad (Bombina bombina), the European tree frog (Hyla arborea) and the Common toad (Bufo bufo). The results were statistically evaluated. Based on them it was established that the Common frog prefers the herb layer, the European Fire-bellied toad prefers semi shaded medium sized pools that do not dry up. The European tree frog and the Edible frog prefer large areas of pools and ponds. More over the edible frog demands ponds that are partially overgrown. The Common toad was represented only with one single individual. Therefore a statistical analasys could not be executed. The whole locality is negatively influenced by local inhabitants who gather here manure and organic waste from their gardens. On locality located near to Dobrkovská Lhotka was transformed from a mining landscape to a pond and three pools. All amphibian species that lived in the locality before reclamation were still present here. Occurrence of Common spadefoot (Pelobates fuscus) was confirmed by the unique finding of a tadpole. Statistical evaluation was not conducted due to the small number and variability of monitored sites.

I monitored the chemical parameters of surface waters in wetlands and watercourses in the vicinity of Lake Medard (newly filled residual pit after brown coal mining). The characteristics of surface waters were described by means of their physical, chemical and biological indicators. The values obtained were compared with normal surface waters in the Czech Republic. I also assessed water quality and determined eutrophication. The chemical composition was compared in space and time. The most important finding is the high variability of waters in a relatively small area. Another is that the examined surface waters do not usually exhibit the typical characteristics of acid mine waters. The locations of interest are characterized by high levels of dissolved solids in water. High concentrations of sulphates are the most problematic of the found anions. In the case of cations, the following dissolved metals had high concentrations: Na, Ca, Mg, Zn, Mn and Fe.

The thesis deals with drawing up the business plan for a newly planned tourism atractivity in Most -- miniature park of the old town of Most, "MiniMost". Its aim is to assess the economic independence of this atractivity, respectively its dependence on the financial support of the town of Most. For this purpose the demand analysis was carried out in form of questionnaire survey in the partner miniature park Klein-Erzgebirge in Saxony and professional excursion around the Most region with students of the University of Economics in Prague. The competition analysis is used to assess the future position of the miniature park MiniMost on the tourism market.

The thesis is based on the recurring proposal to create a main axis Výstaviště (Anthropos) — Mendelovo náměstí — Nádraží. Foundations for the proposal are revised conceptual materials based on architectural design public tender „ Mendlovo náměstí, Urbanisticko – architektonická vyzvaná jednofázová ideová soutěž “ and architectural study created by Kuba & Pilař architekti s.r.o. The objective of the thesis is to complete important urbanistic axis and recultivation, reformalization and reconstruction of the structure and substance of the city and related public space. The task is to create a solution of given area near Mendlovo máměstí with emphasis on representative character, correlation with existing degraded city structure and objects related with in the form of renewal, modification and completion of the current block with mainly commercial and residential function and character corresponding to its central location.

Marek Spěšný - abstract This thesis has the nature of a survey report of a specific area. The task was to localize with the help of microgravimetry anomalous places in an area of a by-pass road construction, where subsurface inhomogeneities may possibly exist due to subsurface and surface historical mining of ceramic clay. The gravimetrical measurements were carried out with a relative gravimeter Scintrex model CG-5 AUTOGRAV. After the first stage of the gravimetrical measurements and following two weeks of recultivation works our assignment was to verify the success of the first measurements by the means of repeated microgravimetric control measurements. The results from both stages of measurement were processed into a 4D gravimetrical form. The results of the 4D gravimetry displayed that contrary to the expectations, the measured gravity of most of the area of interest decreased as much as by 30 ?Gal. We conclude that this is due to the drainage of injected material beyond the recultivated mining area, which washed and carried away a portion of the existing material. Our proposition was also supported by results of repeated leveling, which discovered subsidence of the road at times by up to 3 centimeters.
