Contribution to differentiation of small Moravian and Silesian towns from the point of biogeography and geoecology
Lacina, Jan
This entry differentiate according to 6 indicator set of 128 small cities and their surroundings. Indicators: fytogeography region, vegetation belt, part of woods inside of circle 4 km from town centre, ecological constancy coefficient, conservation and landscapes meaning, actual landuse types.
Biogeographical differentiation of landscape on geobiocoenological approach and its utilization for landscape planning
Buček, A. ; Lacina, Jan
One the method of landscape research is biogeographical differentiation on geobiocoenological approach, founded on differentiation of ecological conditions and comparison of natural (potential) and actual status of vegetation. This approach was used during the assesing of the big civil egineering projects impacts to landscape and also it is scientific base for methodical procedure of systems of ecological stability delimitation.
Contribution to the changes and evaluation of vegetation on landslides and to the problematic of their phytoindication
Lacina, Jan
Relationships between landslides and vegetation cover were studied in Moravian part of Western Carpathian Mountains on selected plots which were affected by landslides evoked by extreme floods in July 1997. It was founded that landslides rises under various vegetation formation – forestal and non-forestal as well. Landslides change ecological conditions for vegetation markedly. A number of species are bounded to landslides, e.g. Equisetum telmateia, which is possible to identify like landslides guides, don’t like phytoindicators.
Changes of the geobiocoen and skeleton of the ecological stability in mining landscape
Lacina, Jan
Anthropogenic disturbances in Ostrava-Karviná mining district cause very significant changes of ecotopes. Actual vegetation reacts on the changes. Frequently, conditions of potential vegetation are changed as well. Even in disturbed landscape has arisen many perspective anthropogenic conditioned biotopes.
Biogeographical research of the effects of antropogenous and natural disturbances
Lacina, Jan
Biogeographical research at the Institute of Geonics of the Academy of Sciences of the Czech Republic is presently focused to impacts of catastrophic factors (floods, landslides) and anthropogenic disturbances of mining activities in vegetation. Changes of biotopes are investigated on flood river basin of Bečva river, on landslides in Western Carpathians and on landscapes changed by mining activities in Ostrava vicinity and Bohemian-Moravian uplands.
Succession in the flood beds of Moravian rivers on example of Bečva a Desná
Lacina, Jan
In flood river basins of alluvium of the Bečva and Desná rivers was found research transects after catastrophic flood in July of 1997 and natural succession was investigated on new ecotopes. Present results shows that succession is dependent on location of biotopes in the face of current active river flow.
Biodiversity changes and cultural landscape character changes during the 20th century on model Tišnov catastre
Lacina, Jan
In the example of cadastre of small Moravian town of Tišnov, which developed without influences of significant natural and anthropogenic disturbances, was found that during the 20th century was residential area 5 times enlarged, but number of inhabitants increased just 2,7 times. CA 50 species of plants and 20 species of animal were lost. Landscape character of garden town was also significantly changed.
Schizophrenia of aesthetically perceptive landscape ecologist
Lacina, Jan
Landscape character is partially subjective and author using perceptions of artists during the perception of the landscape character. Author proposes own method of evaluation of attractiveness of landscape character in result.
Monitoring of landscape changes in surrounding of Rožná induced by uranium mining and milling
Hrádek, Mojmír ; Lacina, Jan
In the paper first results of landscape monitoring in surrounding of Rožná subjected with uranium mining and milling. Landscape monitoring was concentrated to development of the surficial landforms, vegetation and fauna and relationships of runoff condition to erosion.
