了解土地退化和恢复的程度对于指导土地利用政策和管理是必要的，但众所周知，目前可用的土地质量评估是不够的。在这里，我们展示了首次基于统计应用整合科学和当地知识的新方法进行国家评估的结果。在美国 10,000 多个地块完成的定性观察表明，虽然土壤退化仍然是一个问题，但生物完整性的丧失更为广泛。在同一地点收集的定量土壤和植被数据支持评估，并作为监测政策和管理举措（包括应对气候变化）有效性的基线。这些结果提供了支持土地管理者和政策制定者战略决策所需的信息。
An understanding of the extent of land degradation and recovery is necessary to guide land-use policy and management, yet currently available land-quality assessments are widely known to be inadequate. Here, we present the results of the first statistically based application of a new approach to national assessments that integrates scientific and local knowledge. Qualitative observations completed at over 10 000 plots in the United States showed that while soil degradation remains an issue, loss of biotic integrity is more wide-spread. Quantitative soil and vegetation data collected at the same locations support the assessments and serve as a baseline for monitoring the effectiveness of policy and management initiatives, including responses to climate change. These results provide the information necessary to support strategic decisions by land managers and policy makers.
