摘　　要：北部湾经济区沿海分布各类自然保护区划、水产资源保护区、风景旅游名胜区、水产养殖基地等,生态敏感岸线较多,需要控制港口岸线发展对这些生态敏感岸线的占用或影响.根据海洋功能区划、海域生态敏感性要素等规划与资料,确定生态敏感性岸线等级,并数字化获取生态敏感性岸线空间分布.对数字化后港口规划岸线与生态敏感性岸线进行空间叠加分析.结果发现:沿海规划港口利用岸线中有约13.7%占用生态敏感岸线中禁止开发岸线和旅游岸线、增殖区岸线等限制开发岸线,其中广东片区、广西片区和海南片区分别为14.8%、11%和20%;建议对此部分规划港口岸线进行调整或取消,调整后港口利用海岸线总长不超过502km,其中广东片区、广西片区和海南片区分别为185.7,238.7,77.3km.建议在避开生态敏感岸线的前提下,重点开发湛江港、防城港以及洋浦港等港口岸线.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.
