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 oceans are complex ecosystems. The rapid and effective identification of the status quo and damage of the protected areas of marine protected areas is the basis for conservation and restoration efforts. Taking the Haizhouwan Reserve as an example, according to the natural features of its key protected land and sea coasts, the vulnerability assessment of landform protection objects based on four types of 13 indicators including occurrence features, influencing factors, disaster background and human intervention was established Indicator system. Reference to existing research at home and abroad, comprehensively determine the level of each indicator to determine the standard. The evaluation results show that the comprehensive vulnerability indices of Qinshang Island, Zhudao Island, Shaowu, Longwang Estuary and the northern beach of Lian Island are 0.58, 0.62, 0.48 and 0.58, respectively. The vulnerability grades belong to relatively stable, stable and relatively stable, respectively Stable, objectively reflects the status quo of each object of protection. The evaluation model and the criteria for determining the type of geomorphic protected objects can be applied to the protection and management of the special marine landscape.
