CHANGES IN SCATTERED GREENERY IN SELECTED AREA IN THE CZECH REPUBLIC FROM 1953 TO 2014

Abstract. The Land Cover of the Czech landscape could change several times. Reconstructing Land Cover and especially greenery in the past is important for today’s use of the landscape. Two periods were chosen to track changes in scattered greenery, the years 1953 and 2014. The source of information was an historical orthophotomap supplemented with a Military Topographic Map and an orthophotomap supplemented by terrain mapping. The software ArcMap and GuidosToolbox were used. The greenery was highlighted and manually converted to a vector format.

The total area of the monitored territory is 2,190 hectares. In 1953, greenery took up 102 ha and 90 individual green areas were identified here. In 2014, greenery took up 222 ha and it was divided into 113 individual areas. In 1953 the perimeter of all green areas was 41,537 meters; in 2014 the perimeter of all green areas was 89,974 meters. There are two apparent trends here. The first is the simplification of shapes as a result of large-scale management; the second is the formation of a large length of linear greenery and small width with a large perimeter.

The shape of the surface is linked to the area and perimeter. In 1953 this parameter was on average 1.87, and in 2014 the average value was 2.58. Comparing the results of the distance analysis of Label Objects using the GuidosToolbox software found that virtually all green areas were classified differently in 1953 and 2014. The results are completely different and further analysis makes no sense.
