摘　　要：掌握沙区人地系统可持续性状态和发展趋势,对于科学防沙治沙、促进区域协调发展十分重要。本研究选择毛乌素沙地乌审旗、浑善达克沙地正蓝旗和科尔沁沙地奈曼旗为研究区,构建包括人类活动强度、资源-能源状态恶化、环境污染程度和调控能力等4个维度的人地系统可持续性综合评价指标体系,采用组合赋权-TOPSIS和三角模型相结合的方法评估2000—2020年研究区人地系统可持续性水平和发展趋势。结果表明:(1)2000—2020年,内蒙古沙区人地系统可持续性总体呈现向好趋势,空间异质性明显;(2)从子系统变化特征看,各区人类活动强度指数总体呈波动上升趋势,资源-能源状态恶化指数和环境污染程度指数呈波动下降趋势,调控能力指数呈明显上升趋势;(3)从综合可持续性演变看,乌审旗呈现出从不可持续向强可持续发展,生态反应从极差到好;正蓝旗和奈曼旗呈现为从不可持续向一般可持续发展,生态反应从差到中等。随着社会经济的发展和生态治理力度的加大,内蒙古各沙地正积极探索绿色发展之路,但人类社会经济发展与资源能源利用、生态环境保护之间的平衡仍面临挑战,需要针对不同主导因素的人地系统进行差异化管理,以促进区域可持续发展。Grasping the sustainability status and development trend of the human-land system is very important to promote the regional sustainability.In this study,Wushen Banner in the Mu Us Sandy Land,Zhenglan Banner in the Otindag Sandy Land,Naiman Banner in the Horqin Sandy Land were selected as study areas.This research constructed a comprehensive evaluation index system including four aspects of the intensity of human activity,the deterioration of resource-energy status,the degree of environmental pollution and the regulatory capability.The portfolio empowerment-technique for order preference by similarity to ideal solution and a triangular model were used to assess the sustainability level and development trend of the human-earth system during the period of 2000-2020.The results showed that:(1)It is evident that there is considerable spatial variation in the sustainability of human-land systems in the sandy areas of Inner Mongolia.However,the overall trend is one of improvement.(2)The characteristics of the subsystem changes indicate an overall fluctuating upward trend in the intensity of human activities in the study area from 2000 to 2020.This is evidenced by the fluctuating downward trend in the deterioration of the state of resources-energy and the degree of environmental pollution,as well as the ability to regulate and control the index,which showed an obvious upward trend.(3)From the perspective of overall sustainability,the Wushen banner demonstrated a notable shift from unsustainable practices to a more environmentally conscious approach,exhibiting a significant improvement in sustainability and ecological reflection from 2000 to 2020.Similarly,the Zhenglan and Naiman banners displayed a transition from unsustainable activities to a more sustainable and environmentally conscious path,with a notable advancement in sustainability and ecological reflection from 2000 to 2020.With the development of social economy and the increase of ecological governance,Sandy places in Inner Mongolia are actively exploring the ro
