2. The evolution of Shanghai’s space
According to the comparison of green coverage index based on the evidence
of the aerial photographs of 1964 and 1981, the general trends of the changing
of green coverage are:
-
There is little change in the low-coverage districts but substantial change
in the high- and moderate-coverage districts;
-
The green coverage in downtown (garden residential districts) districts
with original high green coverage decreased, but the coverage of the originally
low green-covered districts (factory and shack dweller districts) increased
a little;
-
0utside the downtown area, the green coverage of the moderately green-covered
districts (new dwelling districts) shows both negative and positive changing
trends.
It is worth mentioning that of all the kinds of green land, special green
land decreased very unexpectedly. In the 154 km2 downtown area, a large
part of the decreased green land of 2.034 sq km from 1964-1984 is special
green land. For example, in Huashan Road, special green land has reduced
by 10 times (table 21). These lands were mainly used as profit-making buildings
such as hotels, domicile, dancing halls and bars.

units in Huashan Road
