摘　　要：研究土地利用多功能与多维贫困的耦合关系是开展土地扶贫的有益探索,对巩固脱贫成果和有效衔接乡村振兴战略更具有重要的理论和实践意义。因此,本文以云南省南涧彝族自治县80个行政村为研究对象,构建土地利用多功能与多维贫困耦合度和耦合协调模型,分析2014—2018年土地利用多功能与多维贫困及空间格局特征,探究两者耦合关系及耦合协调发展的时空特征,并划分耦合协调发展类型。结果显示:①研究区2014—2018年土地利用多功能与脱贫发展指数提升较快,空间分布差异性明显,土地利用多功能呈现“一主两副”的空间格局特征,脱贫发展水平空间分布以县城为中心向外延逐渐降低,且北部地区高于南部地区。②研究区2014—2018年土地利用多功能与多维贫困耦合度和耦合协调度的等级提升明显,耦合度从以低度耦合、中度耦合为主提升为以中度耦合、较高耦合为主,耦合协调度从以中度失调为主提升至以轻度失调和初级协调为主;耦合度和耦合协调度空间分布关联性较强,呈现从东北部向西南部递减的布局特征,局部地区形成了新的集聚中心。③研究区2014—2018年土地利用多功能与多维贫困耦合关系的空间分布存在显著的正相关性,空间集聚水平逐渐提升。④耦合协调发展类型包括土地利用多功能滞后型、多维贫困滞后型和同步型3种类型,其中同步型是研究区的主要类型,从2014年的同步滞后型提升为2018年的同步协调型。土地利用多功能滞后型的行政村数量呈增长趋势;多维贫困滞后型的行政村数量呈减少趋势。最后,根据土地利用多功能与多维贫困耦合协调发展类型,针对性地提出解决措施。The study of the coupling relationship between multi-functionality of land use and multi-dimensional poverty is not only a useful exploration of promoting land reform,but also has theoretical and practical significance for consolidating the achievements of poverty reduction and effectively linking up with the rural revitalization strategy.Therefore,with 80 administrative villages in Nanjian Yi Autonomous County of Yunnan Province as the research object,this paper established a model of coupling coordination degree between multi-functionality of land use and multi-dimensional poverty.After analyzing the spatial pattern of multi-functionality of land use and multi-dimensional poverty during the period from 2014 to 2018,it probed into their coupling relationship as well as the spatio-temporal characteristics of coupling coordination development.Meanwhile,it classified the types of coupling coordinated development.The results indicated that:①The comprehensive development level of multi-functionality of land use and the effect of poverty alleviation in the study area improved rapidly from 2014 to 2018,with obvious diversity in spatial distribution.The multi-functionality of land use was characterized by a spatial pattern of‘one center and two sub-centers’.The spatial distribution of the effect of poverty alleviation gradually decreased outwards from the county town as the center,showing a pattern of higher in the north and lower in the south.②The coupling degree and coordination degree between multi-functionality of land use and multi-dimensional poverty in the study area were significantly improved from 2014 to 2018.The coupling degree increased from low and moderate degree of coupling to moderate and high degree of coupling,and the coupling coordination degree improved from moderate imbalance to mild imbalance and primary degree of coordination.There was a strong correlation in the spatial distribution of coupling degree and coordination degree,both of which presented a layout characteristic of decreasing fr
