摘　　要：为了缓解快速城镇化发展中建设用地和农用地的争地矛盾,促进经济建设和农业之间的协调发展,综合运用耦合协调模型、空间自相关模型,以湖南省109个区(县、市)为研究对象,分析了2010—2016年农用地集约利用水平与建设用地规模的时空演变特征及其协调关系。结果表明:(1)农用地集约利用水平和建设用地规模的全局空间自相关Moran′s I指数均为正且有上升趋势,在空间上具有高、低值集聚分布的正相关特征;(2)湘西和湘中南大多数区(县、市)建设用地规模和农用地集约利用水平的耦合协调度小于0.4,呈非耦合协调状态,但2010—2016年向好趋势明显,衡阳市发展迅速;(3)各个区(县、市)在不同的经济、社会发展条件和自然因素影响下形成不同的建设用地规模和农用地集约利用水平,未来要进一步因地制宜采取措施,促进协调发展。In order to alleviate the contradiction between construction land and agricultural land in the process of rapid urbanization development,and promote the coordinated development level between economic construction and agriculture,109 districts(counties and cities)in Hunan Province were used as the research samples.Based on the coupling coordination model and spatial autocorrelation model,the spatiotemporal evolution characteristics and coordination relationship between the intensive utilization level of agricultural land and the scale of construction land in 2010—2016 were analyzed.The results showed that:(1)the global spatial autocorrelation Moran′s I index of agricultural land intensive utilization level and construction land scale was positive and upward trend,which had positive correlation characteristics in spatial distribution;(2)the coupling coordination degree of the scale of construction land and the intensive utilization level of agricultural land in most districts(counties and cities)in western Hunan and central and southern Hunan was less than 0.4,which was in a non-coupled coordination state,but the positive trend was obvious between 2016 and 2010,and the Hengyang City developed rapidly;(3)social and economic conditions and natural factors affected the spatial layout of construction land scale and intensive use of agricultural land,and measures should be taken to promote coordinated development in line with local conditions.
