Structure and Pattern
About
structure
In
this unit we usually refer to structure, but in other sources you will
find that pattern is used to refer to the same thing.
There
are two levels of landscape structure:
- landscape
components, the units within a landscape that are determined
by the physical or natural environment
and
- landscape
elements, the units within a landscape that are determined by
human influences (Ruzicka
et al., 1978)
Why
look at structure
We need to consider landscape structure so we can:
- understand
the three elements of structure (patches, matrix and corridors) and
the way they form patterns in the landscape
- be
able to quantify those elements (indices, scale of analysis)
The
configuration and spatial distribution of landscape features influences
human and other animal use of the land, so it is important to use landscape
ecological concepts and GIS technology for environmental management.
If
the spatial arrangement of landscape features are not considered when
setting up a GIS to solve an environmental problem of an inappropriate
model could be developed
