荒野地区的定义是没有工业规模活动和其他人类压力造成重大生物物理干扰的地区,对于保护生物多样性和维持支撑地球生命支持系统的关键生态过程至关重要。尽管它们很重要,但荒野地区正在迅速地被侵蚀,变得支离破碎。在这里,我们提出了最新的全球陆地荒野地区,这是必不可少的监测其范围内的变化,并积极规划保护干预措施,以确保其保存时间上的相互比较的地图。使用1993年和2009年人类对自然环境的压力地图,我们将荒野确定为所有连续面积> 10,000平方公里的“无压力”土地。这些地方可能在自然状态下运作,代表了全球最完整的栖息地。然后,我们根据公认的“最后的荒野”方法创建了一个具有区域代表性的荒野地图;该方法确定了地球60个地理区域中人类压力最低的10%区域,并确定了10个最大的连续区域,沿着所有连续区域> 10,000平方公里。
Wilderness areas, defined as areas free of industrial scale activities and other human pressures which result in significant biophysical disturbance, are important for biodiversity conservation and sustaining the key ecological processes underpinning planetary life-support systems. Despite their importance, wilderness areas are being rapidly eroded in extent and fragmented. Here we present the most up-to-date temporally inter-comparable maps of global terrestrial wilderness areas, which are essential for monitoring changes in their extent, and for proactively planning conservation interventions to ensure their preservation. Using maps of human pressure on the natural environment for 1993 and 2009, we identified wilderness as all ‘pressure free’ lands with a contiguous area >10,000 km2. These places are likely operating in a natural state and represent the most intact habitats globally. We then created a regionally representative map of wilderness following the well-established ‘Last of the Wild’ methodology; which identifies the 10% area with the lowest human pressure within each of Earth’s 60 biogeographic realms, and identifies the ten largest contiguous areas, along with all contiguous areas >10,000 km2.
