Váchal, J.: Typology and landscape structuralization 169• Primary ecological stability degreeTo each delimitated GES according to its code is joined the primary ecologicalstability degree according to the table.Culture GES Primary ecological Community type CharacteristicsTypestability degreex x x x xThe primary ecological stability degree is multiplied by parameters whichexpressed the deviation form the normal state of the culture. Then the resultantprimary ecological stability degree is noted.Corrective parameters:1. pasture influence2. agricultural activities influence3. wetting4. vegetation origin ifluence5. vegetation function6. vegetation connectivity7. the age of revitalization measurements8. secondary diffused green lay-out• Soil unitsThe attribute table is supplemented with the informations about soil units. Inthe case when the soil unit’s borders are not the same as the borders of GES,the GES is consequently divided into more parts according to it.• Zones A,B,C,DAccording to the resultant primary ecological stability degree the GES are dividedinto particular bioecological zones by this rule:Bioecological zone The resultant primary ecological stability degreeBioecological zone The resultant primary ecological stability degreeA 8,1 - 10B 6,1 - 8C 3,1 - 6D 0 - 3This segmentation enable in ArcGIS interface colouring of particular GESaccording to the zones and so it enables visual interpretation of ecocritical linesA-C, A-D, B-D in the map. The ecocritical lines are not delimitated alongthe roads, because the roads are in their principle unstable and they can’t bestabilized.
