Objective
Compare the spatial pattern of green spaces for five cities in the same region (Flanders, northern part
of Belgium) with a similar historical development: is the spatial pattern of green spaces generalizable?

GSs
are the key to the
provision of
ESs
within urban
areas.
Methodology steps:
• Creation of a buffer;
• Determination of the position
of the centroïd of each green
space;
• Use of landscape indices.
The provision of
ESs
depends on the spatial
pattern of the
GSs
.
The spatial pattern of
GSs
depends on the (1) region (2)
degree/mode of
urbanization.
Characterization of urban
gradient helps to link pattern
with process in urban
ecological studies.
Few existing studies focus
on the comparison of the
GSs
between cities in the
same region.
