摘　　要：在自然因素和人类活动的共同作用下,生态系统格局和质量都发生变化,而生态系统格局和质量的变化直接影响生态系统服务和人类福祉。锡林郭勒盟位于内蒙古中部地区,是京津冀地区的重要生态安全屏障,也是主要的畜产品供应地,研究锡林郭勒盟生态格局演变及驱动因素对于构建内蒙古北方生态安全屏障有重要意义。本研究利用遥感影像,通过分析2000和2015年生态系统类型和质量的变化,探讨资源开发、城市化发展、政策实施等多重因素对生态系统格局演变的作用。研究结果表明:2000-2015年间锡林郭勒盟生态系统质量整体好转,草地生态系统质量中东部地区提高最为明显;草地、灌丛、城镇、裸地、湿地、森林、矿区面积有所增加,农田、沙地、水域面积有所减少;锡林郭勒盟生态系统格局和质量受到人为和自然因素的共同影响,其中,与降水正相关,与温度负相关。GDP与采矿用地显著正相关,退耕还草政策促使农田向草原转移。The pattern and quality of ecosystems would change due to the coupling effects of natural and human activities,and their changes would directly affect ecosystem services and human well-being.Located in the central region of Inner Mongolia,Xilingol League is an important ecological security barrier for the Beijing-Tianjin-Hebei region and is also a major source of livestock products.It is of great significance to study the evolution and driving factors of the ecological pattern of the Xilingol League to build an ecological security barrier in northern Inner Mongolia.In this study,the remote sensing image was used to analyze the changes in ecosystem types and quality of 2000 and 2015 and analyzed the effects of multiple factors included resource development,urbanization development,and policy implementation on the evolution of the ecosystem in Xilingol League.Results showed that the overall quality of the ecosystem in the Xilingol League was improved in 2000-2015,and the quality of grassland ecosystems improved most in the middle and eastern regions.The area of grasslands,shrubs,towns,bare land,wetlands,forests,and mining areas showed an increasing trend,but the area of farmland,sand,and water showed a decreasing trend.The pattern and quality of the ecosystem in the Xilingol League were affected by the interaction of human and natural factors,which had a positive relationship with precipitation while correlated negatively with temperature.There was a positive correlation between the GDP and mining area ecosystem,and the policy of returning farmland to grassland had prompted the transfer of farmland to grassland.
