Researches also show that in Jiaozhou Bay the total area of wetlands decreas ed obviously from 1988 to
2005[18]. Since 1988, the east of Jiaozhou Bay (the four downtown districts in Qingdao) is largely
occupied by artificial buildings. And in 1997, as the construction of Jiaozhou Bay Expressway, the whole
beach almost entirely disappeared. The southwest side of Jiaozhou Bay (Huangdao) is a large proportion
of artificial reclamation area, and the land is fully connected to Huangdao in 2005.
The resulting effect is that the tidal volume of Jiaozhou Bay continues to decline, and the selfpurification
capacity is reduced, while water pollution is increasing in every year. Experts [17] points out
that, if the reclamation is allowed to continue, and which leads to the reduce of sea area, in the near future,
Qingdao Port will become a dead port because of sediment deposition, and the economic advantages of
Qingdao will the no longer exist. To some extent, pollution can be controlled, but the ecological and
environmental impact of reclamation cannot be restored. Therefore, it is of great practical significance to
evaluate on the impact of the reclamation in Jiaozhou Bay.
