摘　　要：基于广西海域红树林、珊瑚礁、海草床等生境数据,在系统保护规划理论框架下,利用Marxan软件构建了广西海域优先保护格局以识别保护空缺。结果表明:广西海域优先保护区集中在三娘湾、合浦、涠洲岛海域,部分区域游离在现有保护体系外。与广西海洋生态红线对比,保护空缺主要分布在沿岸滩涂分布区、红树林分布区和涠洲岛珊瑚礁分布区。本研究首次基于系统保护规划理论,研究了广西海域优先保护格局,为广西海域的保护规划管理提供了科学性建议。The sea area of Guangxi provides important habitat for the biodiversity maintenance of mangrove,coral reef,white dolphin and so on.Based on the data of mangroves,coral reefs,seagrass beds,beaches,wetlands,turtles,amphioxus,white dolphins and germplasm resources,the Marxan software was used to build the priority protection pattern of Guangxi sea area and identify the protection gaps.The results show that the priority reserves in Guangxi are concentrated in Sanniang Bay,Hepu and Weizhou Island,and some areas are not included in the existing protection system.Compared with the marine ecological red line in Guangxi,the protection gaps are mainly distributed in the coastal beach area,mangrove area and coralreef area of Weizhou Island.Based on thetheory of systematicprotection planning,thispaperstudied thepriority protection pattern ofGuangxi sea area for the firsttime,providing scientific suggestions for the protection planning and managementthere.
