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.
