摘要以山东省为例,利用有序聚类方法,基于数据原本特征将时间区间科学地划分为5个时间阶段,从不同的行政级别、用地结构的尺度,运用脱钩指数模型,分析2000—2016年城市建设用地扩张与非农经济增长之间的脱钩状态。结果表明:(1)2000—2016年山东省非农经济密度变化特征在时间序列上表现为明显的5个阶段。(2)从全省尺度看,弱脱钩状态是主要的脱钩关系,用地效率较高;从行政区划尺度看,地级市和县级城市的脱钩状态变化趋势类似,强脱钩城市数增加和扩张负脱钩城市数减少的趋势,表现为用地与经济的耦合关系趋于良好。(3)从用地结构看,不同用地结构扩张与非农经济增长之间的脱钩关系出现多样化的趋势,不同用地在不同发展阶段的增长量不同。脱钩状态与土地和经济政策息息相关,加强用地管控,提高城市化水平,是优化用地与经济之间耦合关系的关键。 Taking Shandong Province as a study area and based on the improved orderly cluster analysis method,this paper divides into five stages from 2000 to 2016.It calculates the decoupling coefficient by the decoupling method and analyzes the decoupling states between urban land expansion and nonagricultural economy growth in Shandong Province based on two scales,namely,administrative level and land structure.It is found that:1)The decoupling relationship between the expansion of urban construction land and nonagricultural economy growth showed five stages in Shandong Province in 2000-2016.2)At provincial scale,the weak decoupling is the main state,the land efficiency is high.At the administrative level,it showed similar trend of decoupling state in prefecture-level and county-level cities,which is the increasement of cities with strong decoupling and the decrease of cities with negative decoupling.It implied that the decoupling relationship between urban construction land and nonagricultural economy is to be good.3)At land structure scale,the decoupling relationship between urban construction land and nonagricultural economy is diversity.The growth of different land structure is different at the different stage.The decoupling state is related to land and economy policies.It put forwards that the government of Shandong should improve urbanization level and control the expansion of land.
