The idea of sustainable development
in the Świdnik planning documents in context
of the city natural system shaping principles
. In
accordance with the concept of sustainable de
-
velopment, contemporary trends in the develop
-
ment of urban environmental systems involve
the following steps: indicating areas performing
environmental functions, maintaining connec
-
tions between them, connecting these areas with
the regional ones and subsequently with national
systems of ecological structures. Completing
these steps is the only way to preserve the su
-
stainability of ecological structures and their self-
-regulating capacities, which is pivotal for con
-
ditions in cities that tend to change dynamically.
This article covers the important topic of the
sustainable development of the city’s natural
system on the example of town Świdnik, SE
Poland. In complexes of the space usage, using
the Braun-Blanquet method from 1964, were
made 248 floristic censuses. Studies have shown
that the largest part of the study area is occupied
by synanthropic of association habitats (ruderal
and segetal). The greatest floristic and phytoso
-
ciological diversity was observed in the indu
-
stry and transport complex. In the multi-family
large-panel complex, which can be described as
a phytosociological poverty complex, the num
-
ber of species is the lowest. Research has shown
that the Świdnik area is poor in valuable and rare
plant species, which is significantly influenced
by the transformation of the natural environment
in favour of technical elements. The most valu
-
able phytocoenosis patches found in the areas
are those from the
Molinio-Arrhenatheretea
and
Artemisietea vulgaris
classes which create co
-
lourful carpets, attractive from both the visual and
environmental point of view as they constitute
a useful base for pollinators. Subsequently, the
results of research were compared with the cur
-
rently applicable legal documents on them (local,
voivodship, national). The research allows to indi
-
cate the conflicts in shaping the cultural landscape
and allows to formulate suggestions for the future
strategy of supporting the existing heterogeneous
ecological system of the city.
