管理和养护世界海洋需要综合关于人类活动的分布和强度及其对海洋生态系统影响的重叠的空间数据。我们开发了一个特定于生态系统的多尺度空间模型，以综合20个海洋生态系统的17个人为生态变化驱动因素的全球数据集。我们的分析表明，没有一个地区是不受人类影响的，很大一部分(41%)受到多个司机的强烈影响。然而，人类影响相对较小的大片地区仍然存在，特别是在两极附近。分析过程和产生的地图为区域和全球努力分配养护资源、实施基于生态系统的管理以及为海洋空间规划、教育和基础研究提供信息提供了灵活的工具。
The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem- specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction ( 41%) is strongly affected by multiple drivers. However, large areas of relatively little human impact remain, particularly near the poles. The analytical process and resulting maps provide flexible tools for regional and global efforts to allocate conservation resources; to implement ecosystem- based management; and to inform marine spatial planning, education, and basic research.
