    Spatial Analysis of Watersheds - A Case Study From Czech Republic

  • Original language description

    Digitised ortho-photomaps of 1995 (1: 10 000 scale) and other spatial data were utilized for studies on land use interpretation and characterisation of three watersheds of Southern Moravia, Czech Republic. The major land uses identified in watersheds are: Vseminka -- forests (48.2%), meadows and pastures (24.2%) and arable lands (9.3%); Frystak- forests (45.4%), arable lands (37.1%) and meadows and pastures (6.1%); Drevnice- forests (81%), meadows pastures (9%) and arable lands (2.7%). From topographical analysis of a digital elevation model in Vseminka, it was found that about 33% of the area falls in 5-10% slopes, while 29% and 18% of the area falls in 10-15% and 15-20% slope ranges respectively. From the analysis of Drevnice watershed, about 36% ofthe area was in the 10-15% slope category, 22% was in the 5-10% category, 21% in the 15-20% category, and 12% in the 20-24% slope category respectively. In Frystak watershed, the major landscapes (35% of the area) had slopes in the range

    Prostorová analýza povodí -- případová studie z České republiky

  • Czech description

    Na základě digitalizovaných ortofotomap a dalších geoprostorových dat byly zjištovány charakteristiky využití území tří povodí s rozdílnou úrovní lesnatosti. Jednalo se o povodí Dřevnice (lesy 81%, louky a pastviny 9%, orná půda 2.7%), Všemínky (lesy 48.2%, louky a pastviny 24.2%, orná půda 9.3%) a Fryštáku (lesy 45.4%, orná půda 37.1%, louky a pastviny 6.1%). Při časové analýze povodí Všemínka v intervalu let 1965 a1997 byla zjištěna značná změna v kategoriích orná půda a louky a pastviny, indikující úbytek orné půdy a její přeměnu v louky a pastviny.
