摘要
[目的]探究陕西省耕地利用生态效率与城镇化进程的耦合协调关系,为陕西省城镇化开发和耕地保护相关政策制定提供理论依据。[方法]基于陕西省2005—2019年各县域面板数据,建立耕地利用生态效率评价指标体系和城镇化发展水平评价指标体系,测算县域单元耕地利用生态效率及城镇化水平,采用耦合协调度模型探索两者间的耦合协调关系,利用空间自相关方法分析各县域单元耕地利用生态效率和城镇化发展的空间格局演化特征。[结果]2005—2019年陕西省耕地利用生态效率水平由0.765下降至0.684,但整体耕地利用生态效率值相对较高,且县域间存在空间差异性,各区县耕地利用生态效率以团块状聚集,陕北、关中和陕南地区间差异随时间逐渐缩小;2005—2019年陕西省综合城镇化水平提高了198.24%,整体呈“中部高、南北低”的分布态势,关中地区是人口城镇化、经济城镇化、土地城镇化的核心区域,变化速率整体表现为:经济城镇化>人口城镇化>土地城镇化;2005—2019年,陕西省县域单元耕地利用生态效率与城镇化耦合度等级主要处于低水平耦合向拮抗耦合过渡阶段,25%的区县耦合度有所提高;2005—2019年,陕西省城镇化与耕地利用生态效率耦合协调类型以轻度失调、濒临失调和勉强协调3个等级为主。研究期内初级协调、勉强协调的区县数量不断增加,整体发展态势不断向好。耦合协调度在空间上表现出较强的正相关性,但在局部空间聚集性上存在明显内部差异。[结论]2005—2019年陕西省城镇化与耕地利用生态效率的耦合协调关系整体呈变好趋势,未来陕西省应制定差异化的经济发展政策,有序推进城镇化发展,同时优化区域发展空间布局,加快形成区域良性互动格局。
[Objective]The coupled and coordination relationship between the ecological efficiency of cultivated land use and the urbanization process in Shaanxi Province was explored in order to provide a theoretical basis for the formulation of policies related to urbanization development and cultivated land protection in Shaanxi Province.[Methods]Based on the panel data of each county in Shaanxi Province from 2005 to 2019,we established system of ecological efficiency of cultivated land use and the evaluation index system of urbanization process,the ecological efficiency and urbanization level of county-level unit farmland use were measured,the coupling coordination degree model was used to explore the coupling coordination relationship between the two,and the spatial autocorrelation method was used to analyze the spatial pattern evolution characteristics of each county-level unit farmland use ecological efficiency and urbanization development.[Results]The level of ecological efficiency of cultivated land use in Shaanxi Province decreased from 0.765 in 2005 to 0.684 in 2019,but the overall ecological efficiency value of cultivated land use was relatively high and there was spatial variability among counties.The ecological efficiency of cultivated land use in each district and county clustered in clusters,and the differences between northern Shaanxi,central Shaanxi and southern Shaanxi gradually decreased over time.The overall urbanization level in Shaanxi Province had increased by 198.24%from 2005 to 2019,with an overall distribution trend of‘high in the central part and low in the north and south’,with the central Shaanxi being the core area for population urbanization,economic urbanization and land urbanization,and the overall rate of change followed the order:economic urbanization>population urbanization>land urbanization.The level of coupling between the ecological efficiency of cultivated land use and urbanization in county units in Shaanxi Province was mainly in the transition stage from low-level coupling to an
