ABSTRACT: Study on landscape spatial pattern in the
center of Chengdu City is based on the Landsat-8 image by using 3S technique
and spatial pattern analysis software Fragstats 3.3. The results showed that
there covered an area of 193.92 km2 in the center of Chengdu City. 55.24% of
the total area was made up of buildings, covering an area of 107.12 km2, and
the overall landscape of impervious ground-based. There were 22,666 patches;
29.67% of the patches were roads. The human interference of buildings, roads
and green space was a maximum; fragmentation of the highest was green space.
The fragmentation of overall urban landscape was high; the diversity was low; the
value of Shannon’s diversity index was 0.63; the value of Shannon’s evenness
index was 0.70. All kinds of landscape distribution were not balanced, and lack
of connectivity. This research puts important reference for creating good urban
landscape space and restoring the natural ecological environment in the
western regions of China.
