摘　　要：从土地利用集约化和生态化的内涵出发,构建了土地利用集约化和生态化评价的指标体系,对陕西省及其10个地市的土地利用集约化和生态化水平进行了评价,并利用耦合协调度模型和障碍度模型分析了两者协调发展的状况及其主要障碍因子。结果表明:(1)2000—2019年,陕西省及其10个地市的土地利用集约化、生态化水平及两者之间的耦合协调度呈现增长的趋势,集约化水平的增长速度快于生态化水平;2012年以后,土地利用集约化水平普遍高于生态化水平;(2)土地利用集约化与生态化的协调度在各个时期均有明显的空间差异性,2019年西安市和渭南市的耦合协调度最高,为中级协调,其他8个地市均为初级协调,未来还有很大的提升空间;(3)影响土地利用集约化的障碍度整体上表现为土地经济效益>土地利用强度>可持续利用程度>土地投入水平,土地利用强度的障碍度大幅提高,土地经济效益的障碍度则大幅下降,而影响土地利用生态化的障碍度表现为污染治理>环境质量>污染控制>污染现状,其中污染治理和污染控制的障碍度呈波动下降的趋势,而污染现状和环境质量的障碍度则呈波动上升的趋势。Based on the connotation of land intensive use and ecological use,an evaluation index system of land intensive use and ecological use was constructed to evaluate the level of land intensive use and ecological use in Shaanxi Province and 10 prefectural cities,and the coordinated development of the two and the main obstacle factors were analyzed by coupling coordination degree model and obstacle degree model.The results showed that:(1)From 2000 to 2019,the land use intensification,ecological level and their coupling coordination degree showed an increasing trend in Shaanxi Province and 10 prefectural cities.The growth rate of the land use intensification was faster than that of the ecological level,and the intensive level was generally higher than the ecological level after 2012.(2)The coordination degree of land use intensification and ecology had obvious spatial difference in each period.In 2019,Xi’an City and Weinan City had the highest coupling coordination degree,which was intermediate coordination,while the other 8 prefectural cities were primary coordination.There is still a lot of room for improvement in the future.(3)The obstacle degree affecting land intensive use was presented as land economic benefit>land use intensity>sustainable use degree>land input level.The obstacle degree of land use degree increased significantly while the obstacle degree of land economic benefit decreased significantly.The obstacles to ecological land use was presented as pollution control>environmental quality>pollution control>pollution status,among which the obstacle degree of pollution control and pollution control decreased,while the obstacle degree of pollution status and environmental quality increased.
