Abstract：
Increasing shipping pressure (SP) deteriorates offshore habitats of large mobile species (LMS) and invalidates marine conservation systems, while the threat of SP to the survival of LMS is not well understood. Here, for the 16 endangered LMS in the western Yellow Sea, we quantified their habitat quality in specific sea areas and conservation capacity of marine protected areas (MPAs) under SP, based on AIS (Automatic Identification System) data and an overlay analysis method for SP surfaces and LMS habitats. Results indicate that three specific sea areas have partially lost habitat function, and their MPA networks have also lost 66.7 %, 59.1 %, and 9.2 % of conservation capacity, respectively. To prevent the continued degradation and extinction of endangered LMS, urgent rescue efforts are needed. This study highlights the importance of monitoring offshore shipping pressure and LMS habitat quality, and the findings contribute to the adjustment of marine spatial planning and LMS protection strategies.
摘要：
不断增加的航运压力（SP）恶化了大型流动物种（LMS）的海上栖息地，并使海洋保护系统失效。而SP对LMS生存的威胁尚不清楚。这里,黄海西部16个濒临灭绝的LMS，我们根据SP量化了它们在特定海域的栖息地质量和海洋保护区（MPA）的保护能力，基于AIS（自动识别系统）数据和SP表面和LMS栖息地的叠加分析方法。结果表明，三个特定海域的栖息地功能部分丧失，他们的MPA网络也损失了66.7%，59.1%,和9.2%的保护能力，分别。为了防止濒临灭绝的LMS继续退化和灭绝，需要紧急救援。这项研究强调了监测海上航运压力和LMS栖息地质量的重要性，研究结果有助于海洋空间规划和LMS保护策略的调整。
