Master's thesis

Optimalizace využití území povodí Čebovského potoka ve vztahu k erozi

Abstract:

Vyskum v DP sa zameriava na najdenie optimalneho vyuzivania krjiny v skumanej lokalite. Optimalizacia bola dosiahnuta statistickymi metodami. Vysledok priklada doraz na materialny prejav krajiny, ale sucastne berie ohlad aj na nematerialne potreby spolocnosti. K nematerialnym potrebam spolocnosti sa pristupovalo ako k limitom jednotlivych moznosti vyuzivania krajiny, hlavne erozie, pretoze zmena vyuzivania krajiny moze dramaticky ovplyvnit prave tento fenomen. Enviromentalny aspekt je obsiahnuty vo viacerych castiach a je mu venovany dostatocny priestor nielen pri limitoch ochrany prirody a podzemnych vod. Zakladom je nesposobit nezvratne neziaduce zmeny v krajine. Vzhladom na komplexnost ponuky na trhu, socioekonomickej situacie, ktoru viacero autorov nezahrnulo do svojho vyskumu sa v diplomovej praci kladol doraz na vyriesenie tejto problematiky taktiez. To som sa pokusil vyriesit volnejsim vysledkom riesenia problematiky, ktory by vyhovoval zmenam na trhu. Takze vysledna optimalizacia je zalozena na moznych zmenach v doterajsom vyuzivani vzhladom na zmenu hospodarskej situacie a to viacucelovou moznostou vyuzitia arealov.

Abstract:

Land use changes may dramatically enhance erosion risk. The research of the diploma thesis is dealing with finding the optimal land use in the research area. Land use optimalization has been found by using advanced statistic methods. The result has been evaluated with emphasis on material natural resources as well as with consideration to non-material needs of society. The non-material needs are presented by limitation of some kinds of land use by erosion. The environmental issue is covered by some results and conclusion of the research. The main aim is the best and optimal use of natural resources without any irreversible impact to the environment for ensuring the needs of the society. The first part is about the theoretical background of the land use optimalization. The second part is dealing first with theoretical basis of erosion and realizing the implementation of RUSLE and USPED models in the area. It outputs partial results, which are the limitation areas for the individual categories. The important part of this part is the terrain research and monitoring the erosion in the area. It makes possible to check the result of the erosion simulation. The third part is focused on sampling and static process of the data. The sampling is based on long term development of the land use in the similar areas. The statistic methods are to compare the difference between the values of factors determining the land use and the differences inside the values for all factors. The p-value is not only the decision border, it is a scaling tool too. The limit values are given by 6σ rule for normal distribution or by median and distribution calculations. The fourth part represents the way of making the synthesis, the main result in a form of map. The last part is the presentation of the results, description of its characteristic features and conclusions.
