Table 4. Matrices of land use/cover
During 1979-2003, results showed that agriculture, barren
and forestry decreased strongly while urban area, shrub and
water body increased, notably the raising of urban area. Table
4(a) indicated that the expansion of urban area was the most
dramatic changes in the region, which was the result of
promptly growing up of economic after applying “DOI MOI”
policy. Based on statistic, 4585.41ha of urbanized area in this
period was calculated, which was nearly as large as the
coverage of urban area in 1979, thus representing an increase
changes in Danang city, Vietnam in hectares
of 73%. Analysing the component of the conversion of growth in
urban area, 42.6% was converted from forestry, 25.3% from
barren and 22.3% from shrub. The coverage of water body
between 1979 and 2003 was significant difference because of the
construction of two new reservoirs in study area. In second period,
from 2003 to 2009, urban area was the only one which
continuously increased, whereas the other classes decreased.
Statistic from Table 4(b) showed the amount of urbanized area as
6428.7ha. The increase of urban area could be represented
as 59%
