荒漠化造成的半干旱和干旱生态系统的退化可以说是这些地区可持续性的主要障碍之一。近几十年来，毛乌素沙漠的生态环境发生了严重的退化，这使得荒漠化空间格局的定量化成为一个重要的研究课题。我们分析了从1986年到2015年的七个时期的荒漠化动态，重点关注五个生态系统服务，包括土壤保持，保水，净初级生产力（NPP），作物生产力和畜牧生产力，所有这些都是在2015年评估的。此外，我们还研究了生态系统服务如何相互关联以及如何受到荒漠化的影响。从研究中得出三个主要结论。首先，在1986年至2015年期间，研究区域的东部经历了全面改善，而西部的荒漠化首先增加，然后扭转了趋势。第二，显着的协同关系，观察三个调节服务（土壤保持，保水，净初级生产力）和两个供应服务（作物生产力和畜牧生产力）。不同类型的生态系统服务之间的强关系，发现只有作物生产力和净初级生产力。第三，在应对日益严重的荒漠化，三个调节服务表现出单调递减的趋势，而两个供应服务遵循驼峰形的响应。
Degradation of semi-arid and arid ecosystems due to desertification is arguably one of the main obstacles for sustainability in those regions. In recent decades, the Mu Us Desert in China has experienced such ecological degradation making quantification of spatial patterns of desertification in this area an important research topic. We analyzed desertification dynamics for seven periods from 1986 to 2015 and focused on five ecosystem services including soil conservation, water retention, net primary productivity (NPP), crop productivity, and livestock productivity, all assessed for 2015. Furthermore, we examined how ecosystem services relate to each other and are impacted by desertification. Three major conclusions are drawn from the study. First, the eastern part of the study area experienced overall improvement while desertification in the west first increased and then reversed its trend during those periods between 1986 and 2015. Second, significant synergistic relationships are observed for three regulating services (soil conservation, water retention, NPP) and two provisioning services (crop productivity and livestock productivity). Strong relationships across different types of ecosystem services were found only between crop productivity and NPP. Third, in response to increasing desertification, the three regulating services exhibit a monotonically decreasing trend, while the two provisioning services follow a hump-shaped response.
