The ecological network joints biodiversity centers into the integrated spatial system
with the ecological corridors as the connecting link of biodiversity conservation spots and
species migration (Yatsentyuk, 2012). Moreover, the vegetation in this area is highly
fragmented with the pronounced synantropization processes as well as in other regions of
Ukraine. The main materials were obtained in field research during the vegetation season of
2013–2017 in Vinnytsia region. For the analysis of phytobiotes, the traditional methods of
field research of the synanthropic flora.
Among the selected synanthropic species apophytes were represented by 120 species in
the Dniestrovsky ecocorridor. The anthropophytes (adventive species) are represented by 98,
species in the respective eco corridor. We have shown that apophytes are mostly represented
by 73 species of hemiapophytes (33.4 %) and 47 species of evapophytes (21.5 %).
Archeophytes head the group classified by the time of entry in anthropogenically transformed
phytocoenoses of the connecting areas (23.4 %). Kenophytes are represented by 44 species
(20.2 %) and euchenophytes – the smallest group – only by 3 species (1.4 %). By the mean of
the distribution, 65 species of acolyutophytes (29.9 %), 28 species of ergasiophytes (12.8 %)
as well as 5 species of xenophytes (2.3 %) were registered. The input of individual historical
and geographical flora groups is used for the evaluation of parameters characterizing
anthropogenic changes in the flora of a certain area. Five indices – synanthropization (IS),
apophytization (IAp), anthropophyzation (IAn), archeophytization (IAr), and kenophytization
(IKn) – were used to determine the degree of anthropogenic transformation of the flora.
The Dniester submeridional ecocorridor has the highest synanthropization index (IS)
value of 37.6 %, which indicates the sufficient flora transformation and the significant
anthropogenic pressure on phytobiota. This is primarily due to the increased areas of the
ploughed fields as well as the possible entry of the synanthropic plant species by railway
tracks. Apophytization index reflects the input of aboriginal species in the vegetation of
anthropogenically transformed ecotopes. IAp was 20.7 % in Dniestrovsky eco corridor.
Anthropophyzation index characterizes the role of invasions of adventitious plants in the flora
synantropization. IAn was 16.03 %. Archeophytization index represents the input of the
species with high naturalization degree entered Ukraine before the 15 century. The
th
background value was 8.8 % in Dniestrovsky. Kenophytization index reflects the intensity of
invasions from the 15 to the 20 centuries. Relatively low values – 3.3 % respectively – show
th
th
the minor role of the kenophytes in the synantropy of the flora of the studied ecocorridors.
The results demonstrate the presence it has been established that the synanthropic flora
of the anthropogenically transformed phytocoenoses was formed under the influence of
aboriginal flora, and now the apophytization prevail over the adventization.
