Ecological consequences connected with sealing of soils in Prague periphery influenced by higway D1
Polická, Petra ; Šefrna, Luděk (advisor) ; Bláhová, Štěpánka (referee)
Sealing of soils in the city fringe is currently reaching a range, which we have never seen in the past. Cities are spreading, commercial development along important highways is rising and hectares of the fertile soils are diseppearing under the tons of concrete, asphalt and other artificial surfaces. The negative consequences of the loss of this important nature resource on the environment and lanscape balance are obvious. Impervious surfaces are the main reason of the run off changes, of the changes in the matter exchange between ekosystems and of the loss of a lot of important soil functions. The landscape is being homogenized and its fragmentation is rising. This work warns against irresponsible sealing of fertile agricultural soils surroundings the highway D1 in the periphery of Prague. Two thirds of sealed soils belong to the first classes of soil protection (luvisols), which can be built up only exceptionally. Contemporary legislative in the Czech Republic is visibly poor and it is necessary to accept more efficient control instruments.
