A usability of remote sensing for evaluation of economic impact of drought
FRANKOVÁ, Lenka
Drought is a natural phenomenon which has got an important influence on human economic activity and other areas of human life. This work, based on literary sources, summarizes current available information about the issue of drought. The work is primarily focused on agricultural problems with drought in the Czech republic but summarizes even the ohter problems of drought, for example sociological impacts. There is also a perspective given to the generally used methods for studying and evaluation of drought. Considering the relation of drought to water stress of plants and vegetative covering the problems are also summarized. Besides the evaluation of drought and related problems, the work deals with the question of the possibility of usage of technology for remonte sensing the Earth in evaluation of drought and water stress of vegetative covering which may be the indicator of the drought. There are discussed possibilities of usage optical and thermal methods. The problem of drought is duscussed in broad context of ecological function of the landscape. Potencial human influence on drought is duscussed.

Analysis of current condition, revision and testing of new procedures during the formation of structural elements TSES selected cadastral areas Novohradsko.
SÍČOVÁ, Petra
Territorial system of ecological stability is artificial, interlinked set of natural and altered similar to natural ecosystems that sustain the natural balance. In selected area Novohradsko was approved plan TSES already a decade ago. This study revises the area according to the standard method that is based on biological evaluation. During updating natural segment of area are being tested and used the new procedures, which include the functional aspects of the landscape. Specifically, they are based on physico-chemical evaluation. Data from the mapping of the defined area were processed and analyzed using GIS tools. The method of the functional aspects of landscapes can usefully complement the standard methodology with the objective identification of optimal functional and dysfunctional areas, which are an alternative to the segments of the skeleton of ecological stability.
