Abstract: Climate changes and urbanization are two main factors making human beings more vulnerable to disasters, and the two factors superimpose with each other in urban agglomeration. Furthermore, population, industry and infrastructure are highly centralized in urban agglomerations, which would become the high-risk areas being vulnerable to disasters and easily suffering great losses. Five urban agglomerations in the coastal region of China have strong economic strength and are important engines for driving economic and social development. On the other hand, they are located in the interaction area of land and sea, and suffer from the double impacts of sea and land disasters. Moreover, the disaster-bearing bodies of five urban agglomerations are too big, and accordingly they easily suffer great losses under the background of climate changes. For the reason mentioned above, national related departments should fully realize the urgency of coping with the impacts of climate changes on urban agglomerations in the coastal region, put forward coping strategies as soon as possible, and take into account the impacts and adaptive measures in socio-economic development plans of the coastal urban areas.

Key words: climate change, sea level rise, urban agglomeration, coastal region
