Abstract:The coastline of Beibu Gulf Economic Zone (BGEZ) was covered by variety of ecological sensitivity coastlines, which include natural protected areas, aquatic resource protection areas, scenic areas and aquaculture sites. They are widely distributed in the whole coastal areas of Guangxi, coast areas of Leizhou Peninsular in Guangdong, and the west coast of Hainan. All these coastlines are very sensitivity to port development, which will encroach or put much pressure on these areas. In order to minimize the impact of port development on coastlines, sensitivity coastlines need to be categorized and strictly controlled for policy decision and management. Based on digitalized maps and overlay analysis, the sensitivity of coastline was assessed and classified. These kinds of coastlines were further compared with those that were planned for port development in the corresponding plans. The results show that 13.7% of planned port coastlines were overlapped with sensitivity coastlines, with 14.8%, 11%, and 20% in Guangdong, Guangxi, and Hainan, respectively. In order to better protect the sensitivity coastlines, it was recommended that the overlapped coastlines in the corresponding port plans should be readjusted or cancelled. And the total length of port coastline should be controlled in 502 km, with 185.7 km, 238.7 km, and 77.3 km in Guangdong, Guangxi, and Hainan, respectively. It is also suggested that port development priority area should be given to Zhanjiang Port, Fangcheng Port, and Yangpu Port in Beibu Gulf Economic Zone.
