生态系统服务功能作为人类社会赖以生存的物质基础和自然资源，对生态系统的可持续发展起着至关重要的作用。土地用途的改变可以显著改变生态系统服务的提供。由于自然因素和人为因素的影响，我国北方农牧交错带土地利用结构在过去几十年中经历了复杂的变化。因此，客观评价北方农牧交错带生态系统服务价值损失，为可持续发展决策和政策评估提供科学依据具有重要意义。然而，在生态系统服务方面，只有少数的整体性研究考虑了农业区和牧区作为控制，以评估时空变化的农牧交错带。在这项研究中，我们定量评估了1980年至2015年之间农牧交错带与农业区和牧区相比的ESV损失。结果如下：（1）农牧交错带土地转化的主要特征是大面积的草地转化为耕地，其土地转化密度显著高于农区和牧区;（2）在空间尺度上，农牧交错带生态系统价值损失大于农区和牧区而在时间尺度上，其丢失顺序为：1990-2000 > 1980-1990 > 2000-2015;农牧交错带生态系统价值损失较大，主要是由于草地转化为耕地，耕地变为未利用地，草地变为建成区。虽然在1990年代末实施保护政策后，这些土地转换受到遏制，但有向牧区扩展的趋势。因此，我们认为人为干扰是农牧交错带生态恶化的主要原因。该研究为限制人类活动提供了措施，并为ESV在可持续发展中的应用提供了前景。
As the material base and natural resources of human society, ecosystem services play an essential role in the sustainable development of the ecosystem. Land-use conversions can remarkably alter the provision of ecosystem services. Owing to natural factors and human interventions, the land-use structure has undergone complex changes over the past few decades in the agro-pastoral ecotone of Northern China. Hence, objectively evaluating the losses of ecosystem service values (ESVs) in the agro-pastoral ecotone of Northern China and accordingly implementing decision-making and policy evaluation for sustainable development is remarkably important. However, in terms of ecosystem services, only few holistic studies have considered the agricultural zone and pastoral area as controls to assess the spatiotemporal variation in the agro-pastoral ecotone. In this study, we quantitatively evaluated the losses of ESVs in the agro-pastoral ecotone compared to those in the agricultural zone and pastoral area on a macro-scale between 1980 and 2015. The results were as follows: (1) the main characteristic of land conversions was that large areas of grassland were converted into cultivated lands in the agro-pastoral ecotone, and its density of land conversions was remarkably higher than that in the agricultural zone and pastoral area; (2) on the spatial scale, the agro-pastoral ecotone lost more ESVs than the agricultural zone and pastoral area (P< 0.05); in contrast, on the temporal scale, the losses were noted in the following order: 1990–2000 > 1980–1990 > 2000–2015; and (3) the agro-pastoral ecotone lost more ESVs, mainly owing to three land conversions, which were grassland transformation into cultivated land, cultivated land transformation into unused lands, and grassland transformation into built-up areas. Although these land conversions were curbed after the implementation of protection policies at the end of the 1990s, they had a tendency to expand to the pastoral area. Therefore, we think that human interference is the main cause of ecological deterioration in the agro-pastoral ecotone. This study provides measures for restricting human activities and a perspective for the application of ESVs in sustainable development.
