摘　　要：经济转型背景下把握土地利用结构状况旨在为协调区域经济建设质量与用地结构优化关系提供依据。运用信息熵和SSM模型分析了2005—2016年南京市土地利用结构时空格局差异,并构建了经济计量模型探讨驱动因素。结果表明:(1)根据信息熵动态演变规律发现,南京市土地利用结构信息熵具有明显阶段性,2005—2009年为持续增长期(无序),2010—2012年为持续下降期(有序),2013—2016年为波动上升期(无序);(2)对信息熵、均衡度和优势度总体分析表明,受信息熵变动趋势影响,研究期内南京市土地利用结构均衡度呈上升—下降—上升趋势,优势度与之相反,其中农用地结构为无序—有序趋势,建设用地结构为有序—无序趋势;(3)不同地类空间演变上,农用地和其他用地均属衰减性结构,其中耕地和牧草地具有显著的挤出效应;建设用地基本为增长性结构,其中城乡建设用地和交通水利用地具有明显的补给效应;(4)南京市“四大片区”不同地类竞争力具有显著的空间差异,主城区为中值区—低值区状态,江北新区和近郊区为中高值区—高值区状态,远郊区处于高值区状态;(5)南京市土地利用结构时空格局演变状况主要受土地资源禀赋、经济发展水平、产业结构调整和土地管理政策因素的影响。Study on regional land use structure is to provide a basis for coordinating the relationship between the quality of regional economic construction and the optimization of land use structure under the background of economic transformation.This paper used information entropy model and SSM model to analyze the difference of spatiotemporal pattern of land use structure in Nanjing City from 2005 to 2016,and build econometric model to discuss its diving factors.The results show that:(1)according to the general dynamic evolution rule of information entropy,information entropy of land use structure in Nanjing City had obvious periodicity and it showed that the period from 2005 to 2009 was a continuous growth period(disordered),the period from 2010 to 2012 was a continuous decline period(orderly),and the period from 2013 to 2016 was a fluctuation uplift period(disordered);(2)the general analysis of information entropy,equilibrium degree and superiority degree showed that the equilibrium degree of land use structure in Nanjing City presented the trend of‘increase—decrease—increase’and superiority degree was the opposite,among which the agricultural land structure was the evolution trend of‘disordered—orderly’,while the construction land structure was the evolution trend of‘orderly—disorderly’;(3)from the evolution of different geodetic spaces,agricultural land and other land belonged to attenuation structure,among which cultivated land and grassland had a significant crowding-out effect;construction land basically belonged to growth structure,among which land for urban and rural construction and for transportation and water conservancy showed the significant supply effect;(4)the competition of different land use type in‘four areas’of Nanjing City showed the significant difference in space configuration,that was the main urban area was in state of‘middle value zone—low value zone’,Jiangbei New Area and the near suburbs were in state of‘middle-high value zone—high value zone’,and the far s
