Dramatic land use change in China affects ecosystem degradation and restoration. Identifying the evolving role of land use in ecosystem degradation and restoration in China is essential for sustainable land policy making. However, it is not clear how land use affects ecosystem degradation and restoration over time. Here, we used the revised benefit transfer approach and spatial statistics based on land use data to determine the evolving role that land use plays in ecosystem degradation and restoration in China during 2000-2020. The study results pointed out that the deterioration of the forestland ecosystem during the study period was the main reason for ecosystem degradation, while the conversion of arable land to forestland was the main cause for ecosystem restoration. Every 1% increase of land use intensity in the periods 2000-2005, 2005-2010, 2010-2015, and 2015-2020 resulted in -1.754%, 0.697%, 1.098%, and -0.058% of the changes in ecosystem services, respectively. This study provided important policy implications for future sustainable land use management in China.
中国剧烈的土地利用变化影响着生态系统的退化和恢复。确定土地利用在中国生态系统退化和恢复中的演变作用，对于可持续土地政策的制定至关重要。然而，目前尚不清楚土地利用如何随时间影响生态系统的退化和恢复。在这里，我们使用修正后的效益转移方法和基于土地利用数据的空间统计方法，来确定在 2000-2020 年间，土地利用在中国生态系统退化和恢复中扮演的演变角色。研究结果指出，在研究期间，林地生态系统的恶化是生态系统退化的主要原因，而耕地向林地的转化是生态系统恢复的主要原因。在 2000-2005 年、2005-2010 年、2010-2015 年和 2015-2020 年期间，土地利用强度每增加 1%，生态系统服务的变化分别为-1.754%、0.697%、1.098%和-0.058%。本研究为中国未来可持续土地利用管理提供了重要的政策启示。
