27 cities in the Songhua River basin had flood control requirements
and there were about 13 million people at the end of 1997. The main
flood control cities had 10, such as Harbin, Changchun and other
cities. There were 9 million and 38 thousand people. Some cities were
included in the national key flood control city by the state, such as
Harbin, Changchun, Jilin, Qiqihar and Jiamusi. Table 1-6 was related
to the major flood control cities. Now the main flood control measures
for the main flood control cities were the levees, but the standard
of levee flood control was low. It could be seen that 9 cities hadn’t
reached the flood control standard.
The standard of flood control in the main cities was relatively low in
the Songhua River basin. There were 10 main flood control cities that
were Harbin, Changchun, Jilin, Songyuan, Daqing, Qiqihar, Yichun, Mudanjiang,
Jiamusi and Ulanhot, 5 of which were the national key flood control city,
such as Harbin, Changchun, Jilin, Qiqihar and Jiamusi.
