Figure 6. The number of demolished and newly built Hutong
In Figure6, the number of newly built Hutong is much less
than the demolished Hutong. In the case of demolished Hutong,
three periods decrease acutely, respectively 1949-1965,
1990-2003 and 2003-2005.
4) Analyze to the transition of Hutong
length decreased by 14%.
From 2005 to 2007, the number of Hutong decreased by 19
(1%), decreased by 7 km (2%). These numbers are much less
than the numbers of Hutong from 2003 to 2005. The decreasing
trend had been hold back effectively, due to the appropriately
protection to Hutong as cultural heritage by the government of
Beijing.

2) Hutong inside of the protection regions of history and
culture
The transition of Hutong from 1949 to 2007 has significant
relationship with the transition of Beijing. During 58 years from
1949 to 2007, widely housebreaking and construction has taken
place in Beijing, so Hutong had been changed enormously.
From 1949 to 1965, during 16 years, the number of Hutong
decreased by 691 (22%), while the length of Hutong only
decreased by 45km (6%), these data indicates, most of the
transition in this period are rename to Hutong for the case of
unite, a few Hutong has been demolished. In fact, in 1965, the
government has renamed the Hutong on a large scale.
From 1965 to 1980, both of the number and the length of
Hutong keep steadiness. From 1980 to 1990, economic and
society reformation is on the initial stages, Hutong keep
steadiness, too.
From 1990 to 2003, during 13 years , along with the further
reformation of economic and society, a large number of unsafe
houses were broken up, the number of Hutong decreased by 683
(30%) acutely, the length decreased by 201km (30%).
From 2003 to 2005, Hutong keep on decreasing, during 2 years,
the number of Hutong decreased by 175 (11%), the length
decreased by 68km (14%). Some Hutong has demolished
partially, that’s why the number decreased by 11% while the
There are 25 protection regions of history and culture [13 ] in the
imperial city in 2001, .and more 5 added in 2004. Now, there
are 30 regions in the imperial city.
