Human activities are altering natural areas worldwide. While our ability to map these activities at fine scales is improving, a simplistic binary characterization of habitat and non‐habitat with a focus on change in habitat extent has dominated conservation assessments across different spatial scales. Here, we provide a metric that captures both habitat loss, quality and fragmentation effects which, when combined, we call intactness. We identify nine categories of intactness of the world's terrestrial ecoregions based on changes in intactness across a 16‐year period. We found that highly impacted and degraded categories are predominant (74%) and just 6% of ecoregions are on improving trajectories. It is essential that management of degrading processes be targeted in international agendas in order to ensure that Earth's remaining intact ecosystems are effectively conserved and restored in order to achieve effective conservation outcomes.

生态区域完整性的重大损失凸显了采取全球协调行动的紧迫性

人类活动正在改变世界范围内的自然区域。尽管我们在精细尺度上绘制这些活动的能力正在提高，但生境和非生境的简单二元表征（着重于生境范围的变化）主导了不同空间尺度上的保护评估。在这里，我们提供了一个指标，该指标可同时反映栖息地的丧失，质量和碎片化的影响，将它们结合起来称为完整性。我们根据16年期间的完整性变化，确定了世界陆地生态区域的9种完整性。我们发现，受到高度影响和退化的类别占主要地位（74％），而只有6％的生态区正在改善轨道。至关重要的是，必须将降级过程的管理作为国际议程的目标，以确保地球的安全。
