2. Pollution control and city afforestation
Environmental pollution has basically been controlled. Environmental quality
has been largely improved through expansion of urban gas usage, the introduction
of heat supply networks, afforestation
and environmental management. First, each of the districts in the city
has achieved the accepted standard as "soot
controlled areas" through the following projects: the treatment of key
pollution sources such as metallurgical, steel and forging factories; a
project to provide central heating, which has the capacity to heat 8 million
m2; and the removal of more than 100 boilers from service. As
a result, the quality of air has been improved throughout the city. Second,
the northern sewage treatment factory, on which construction was started
in 1994, now has a daily treatment capacity is 400 thousand tons. Together
with the construction of a sewage processing factory in Shenyang City,
the total quantity of pollutants from sewage has declined. In addition,
the requirement for enterprises to treat sewage and apply for pollutant
discharge permits, and the simultaneous reconstruction and improvement
of the 370 sewage processing units in the city have contributed noticeable
to the decline in pollution. Third, combined with the reconstruction of
old property, more than 100 enterprises that were adversely affecting local
residents have been moved and incorporated; thus 70 noise-controlled areas
totalling almost 30 km2 have been formed, directly benefiting
1 million people.
A preliminary urban green system has been established, and the capacity
for cleaning up the environment is gradually improving. The rate of introducing
urban green cover has reached 27 per cent compared with 22 per cent in
1990, while the per capita green land area is 4.23 m2. Shenyang
thus has better ecological environment and living conditions than ever
before.
