摘　　要：海洋是个复杂的生态系统,快速有效识别海洋保护区保护对象的现状稳定性和受损情况是开展保护和恢复工作的基础。以海州湾保护区为例,根据其重点保护的海岛海岸地貌的自然特征,构建了基于赋存特征、影响因素、灾害背景和人工干预的4类13个指标的地貌类型保护对象脆弱性评价指标体系。参考国内外已有研究,综合确定各指标等级判定标准。评价结果显示,秦山岛、竹岛、龙汪河口沙咀、连岛北侧沙滩的脆弱性综合指数分别为0.58、0.62、0.48、0.58,脆弱性等级分别属于相对稳定、稳定、相对稳定、相对稳定,较为客观反映了各个保护对象的现状。构建的地貌类型保护对象的评价模型和指标判定标准可应用于海洋特殊地貌景观的保护与管理。The ocean was a complex ecosystem. Rapid and effective identification of the current status of protected areas were the basic work for conservation and rehabilitation efforts. This study was based on Haizhouwan national marine park, a national marine protected area in Jiangsu. According to the natural features of the landforms, a neritic land- form vulnerability index system was established, including four indices and 13 factors. The indices consisted of the occurrence characteristics, the influence factors, the disaster background and the human intervention. With the comprehensive consideration of the existing research results, the factors valuation criteria were established for the assessment of landform vulnerability. This study conducted analytic hierarchy process for the assessment results, so as to get the vulnerability index of Qinshan Lsland, Bamboo Lsland, the Longwang estuary spit, and the north shoreline of Lian Is- land, which were 0. 58,0. 62,0. 48,0. 58, respectively. The stability of Bamboo Island was the best, which objectively reflected the current situation of each protected object. The results of the study can provide references to the protection and management of special landscape. The evaluation model and index criteria could be applied to other protected landforms.
