| Zusammenfassung |
| Being bordered by the South China Sea and with long coastline,
the coastal zone of Guangdong Province is often under severe risk
of storm surges, as one of a few regions in China which is seriously
threatened by storm surges. This article systematically analyzes the
vulnerability factors of storm surges in the coastal area of Guangdong (from
Yangjing to Shanwei). Five vulnerability assessment indicators of
hazard-bearing bodies are proposed, which are social economic index, land
use index, eco-environmental index, coastal construction index, and
disaster-bearing capability index. Then storm surge vulnerability assessment
index system in the coastal area of Guangdong is established. Additionally,
the international general mode about coastal vulnerability assessment is
improved, and the vulnerability evolution model of storm surges in the
coastal area of Guangdong is constructed. Using ArcGIS, the vulnerability
zoning map of storm surges in the study region is drawn. Results show that
there is the highest degree of storm surge vulnerability in Zhuhai, Panyu,
and Taishan; second in Zhongshan, Dongguan, Huiyang, and Haifeng; third in
Jiangmen, Shanwei, Yangjiang, and Yangdong; fourth in Baoan, Kaiping, and
Enping; and lowest in Guangzhou, Shunde, Shenzhen, and Longgang. This study on
the risk of storm surges in these coastal cities can guide the land use of
coastal cities in the future, and provide scientific advice for the
government to prevent and mitigate the storm surge disasters. It has
important theoretical and practical significance. |
