近几十年来，受气候变化和人类活动的影响，中国北方农牧交错带土地利用格局发生了复杂的变化，可能危及生态系统服务功能的提供。因此，为了可持续的土地管理，应该评价和监测生态系统服务。基于Landsat TM/ETM数据，对1980—2015年农牧交错带3个区域的生态系统服务价值（ESV）损失进行了定量评价。结果表明：(1)农牧交错带土地转化的主要特征是草地大面积转化为耕地；(2)在空间尺度上，农牧交错带的ESV损失呈东北向西南方向的“倾斜面”，且农牧交错带东北段的ESV损失大于中部和西北部（p < 0.05），时间尺度上的ESV损失顺序为1990 ~ 2000年bbb、1980 ~ 1990年bbb、2000 ~ 2015年bbb；(3)农牧交错带ESV损失较大，主要是由于草地向耕地转化、草地向未利用地转化、草地向建成区转化、耕地向建成区转化4种类型的土地转化所致；(4)虽然在20世纪90年代末实施保护政策后，这些土地利用得到了遏制，但由于降水减少和气温升高，未来农牧交错带将面临更加严峻的形势；(5) 1990-2015年，人口增长的总体动态过程逐渐向人口稀少的牧区扩展。因此，我们认为人为干预是农牧交错带生态恶化的主要原因。该研究为全面认识土地利用变化的生态环境效应的区域差异提供了参考，有助于客观评价中国北方农牧交错带生态文明建设。
Being subject to climate change and human intervention, the land-use pattern in the agro-pastoral ecotone of Northern China has undergone complex changes over the past few decades, which may jeopardize the provision of ecosystem services. Thus, for sustainable land management, ecosystem services should be evaluated and monitored. In this study, based on Landsat TM/ETM data, we quantitatively evaluated the losses of ecosystem service values (ESV) in three sections of the agro-pastoral ecotone from 1980–2015. The results were as follows: (1) the main characteristic of the land conversions was that a large area of grassland was converted into cultivated land in the agro-pastoral ecotone; (2) on the spatial scale, the ESV losses of the agro-pastoral ecotone can be called an “inclined surface” in the direction of the northeast to southwest, and the northeastern section of the agro-pastoral ecotone lost more ESV than the middle and northwest sections (p < 0.05), on the temporal scale, the order of losses was 1990–2000 > 1980–1990 > 2000–2015; (3) the agro-pastoral ecotone lost more ESV, which was mainly due to four kinds of land conversion, which were grassland that was transformed into cultivated land, grassland transformed into unused land, grassland transformed into built-up areas, and cultivated land transformed into built-up areas; (4) although these land conversions were curbed after the implementation of protection policies at the end of the 1990s, due to reduced precipitation and increasing temperatures, the agro-pastoral ecotone will face a more severe situation in the future; and, (5) during the period of 1990–2015, the overall dynamic processes of increasing population gradually expanded to the sparsely populated pastoral area. Therefore, we believe that human interventions are the main cause of ecological deterioration in the agro-pastoral ecotone. This study provides references for fully understanding the regional differences in the ecological and environmental effects of land use change and it helps to objectively evaluate ecological civilization construction in the agro-pastoral ecotone of Northern China.
