Abstrakt
The analysis of the geographical and historical structure of the flora of different
biotopes and the anthropogenic indices are of cognitive significance in the process of
transformation of communities. Differentiated biotopes (exploited sand and gravel pits, fallows,
arable fields, warm slopes, shrubs, alleys, midfield ponds and midfield meadows, forest
habitats, shoulders of forest roads and car parks adjacent to forests) in the area of the south
western part of Nizina Szczecińska (Szczecin Lowland) and the western part of Pojezierze
Drawskie (Drawsko Lakeland) were taken into consideration in the studies. Apart from these
biotopes the results of Chmiel's studies concerning NE Wielkopolska, the protected areas:
nature reserves, landscape parks, ecological utilized areas and non-protected areas were used.
In the flora of the studied biotopes indigenous species dominate species of non-native origin
and among spontaneophytes more abundent are synenthropic spontaneophytes (apophytes).
Among anthropophytes the most frequently represented are archeophytes, whereas
keneophytes occur much more rarely. The smallest transformation of the flora is observed in
protected areas of NE Wielkopolska (N = 34.1%) and within the range of such biotopes as
midfield ponds and midfield alleys (N = 32.9–33.3%) and in forest habitats of Western
Pomerania (N = 30.8–31.8%). Within the area of exploited pits the largest indices of proper
synanthropization were recorded. The Sw indices are the largest for the flora of the pits (Sw
varies from 78.9 to 94.1%), approximate values of proper synanthropization were also
determined for fallows and the largest - for arable fields (Sw = 91.3–98.2%). The lowest values
of proper synanthropization, not exceeding 60%, were characteristic of the flora of NE
Wielkopolska, of midfield ponds, midfield meadows and forest habitats (Sw indices are the
lowest and they vary from 35.9 to 45.0%). The index of potential synanthropization of the flora is
larger by 25–33% of the Sw value in all the biotopes. The values of proper apophytization (Apw)
and potential apophytization (App) of the flora are similar in the flora of the studied biotopes to
the indices of synanthropization and their values are smaller by 25–33%. The largest indices of
archeophytization (Ar = 30.8−35.7%) are achieved by the flora of arable fields and fallows,
slightly smaller (15.8−18.9%) − by the flora of the pits, the index of the remaining biotopes
(forest habitats, shrubs, alleys, midfield ponds and midfield meadows) does not exceed 10%.
The contribution of kenophytes to the flora of the studied biotopes is very slight. It is confirmed
by very small indices of kenophytization.
