全世界海洋沃茨受到影响海洋生态系统的人类活动日益增加的压力。欧盟的若干指令要求评估海洋环境状况;特别是《海洋战略框架指令》对人类活动的管理采用生态系统办法。在这方面，以标准化和可比的方式绘制压力图是评估人类压力的空间格局、时间变化和生态影响的关键步骤。在MSFD中，直接影响海底的压力源之一是物理损失（PL）压力，代表海洋生境的永久或长期改变。本研究的主要目的是提出一种方法来估计的空间范围内的初步评估阶段的MSFD的框架PL压力。此外，考虑到与PL相关的人类活动导致底栖生境的丧失，并且地中海的特点是敏感和受保护的生境，如生物基质MSFD，PL压力的分布与海底生境的分布重叠，以估计生物基质的丧失。这项研究是一个有用的工具，建立PL压力的基线条件，比较未来的条件，并评估不同的管理方案。此外，它还可以将压力趋于积累的领域确定为“热点”，以便在今后的影响分析中予以重点关注，并确定压力源很少的领域。
All over the world marine waters are under increasing pressure from human activities affecting marine ecosystems. Several EU Directives require assessment of the condition of marine environments; in particular the Marine Strategy Framework Directive (MSFD) applies an ecosystem approach to the management of human activities. In this context, the mapping of pressures in a standardized and comparable way is a critical step to assess the spatial pattern, the temporal change and the ecological impacts of human pressures. Within the MSFD, one of the stressors directly affecting the seafloor is the Physical Loss (PL) pressure, representing the permanent or long-term alteration of marine habitats. The main purpose of this study was to propose a method to estimate the spatial extent of PL pressure in the framework of the Initial Assessment phase of the MSFD. Furthermore, considering that human activities PL-related cause the loss of benthic habitats, and that the Mediterranean sea is characterized by sensitive and protected habitats such as the biogenic substrates sensu MSFD, the distribution of PL pressure was overlaid with the distribution of the seabed habitats to estimate the loss of biogenic substrates. This study represents a useful tool for establishing the baseline condition for PL pressure, to compare future conditions and to evaluate different management scenarios. Moreover, it allows identification of the areas where pressure tends to accumulate as ‘hot spots’ on which to focus in future impact analyses and the areas where few stressors are present.
