【摘要】 城市产业是在城市产业结构转型和城市用地演化的相互作用中实现的,城市的产业结构转型是一个从量变到质变的过程,而城市用地形态和布局的发展却具有相对滞后性。因此,为了给产业结构转型提供空间支撑,必须探究城市产业与土地资源结构、形态的内在联系和演变规律,才能优化土地配置,对城市用地结构做出预先调控。本文以“深莞惠”经济圈作为研究区,通过研究区1990、1999、2005和2008年的Landsat TM/ETM和SPOT5遥感影像数据以及统计数据,提取土地利用信息和社会经济统计信息,对城市用地扩展速度和扩展强度、信息熵、城市紧凑度及格网自相关系数进行定量计算,对比分析“深莞惠”经济圈三城市18年间城市用地的演变;进而从产业发展阶段、土地经济密度、耕地占用与经济增长的脱钩关系三方面分析研究区城市用地与产业发展的关系。结果表明:“深莞惠”经济圈内三个城市用地的演变都反映了产业政策的调整过程,而城市用地形态格局对产业发展也有影响。1990到1999年是深圳和东莞外延式扩展最快的阶段,土地信息熵均在1999年达到了最高,深圳带状聚集发展的结构形成,城市紧凑度跨越式进入更紧凑阶段,东莞则呈现“低、小、散”,1999年格网自相关系数≥4级的区域深圳占80%,东莞仅占29%,而惠州为34%,由于重大项目带动和有序的规划,使惠州形成块状发展的良好趋势。1999到2005年,深圳和东莞的土地信息熵递减,说明建设用地占主导的“完全城市化”发展趋势明显,东莞“由线连片”格局形成,城市紧凑度也进入更为紧凑的阶段,格网自相关系数≥4级的面积比重提高到72%。2005年以后,随着“双转移”战略的实施,惠州产业用地呈现“遍地开花”局面,城市紧凑度趋于松散,格网自相关系数≥4级的面积比重从前一阶段的55%下降到48%。由于东莞在一定时期内城市形态分散,导致土地经济密度长期低于深圳和惠州,2004年后随城市用地形态的聚集才稳步提高。深圳、东莞、惠州的耕地占用与经济增长脱钩率的最低值分别在1998、2002、2005年,都是在进入工业化后期,第二产业的比重超过50%,第三产业的比重超过30%,第二产业内部轻工业与重工业的比重相对均衡的阶段出现;但东莞的城市用地破碎形态导致脱钩关系不稳定,且以相对脱钩为主。在“深莞惠”经济圈内,东莞的发展轨迹和方向朝着“深圳模式”迈进,深圳对东莞、惠州具有示范和拉动作用,“深莞惠”经济圈的一体化融合有利于缓解用地容量限制,但需注意防止产业同构化倾向等问题。“深莞惠”经济圈揭示的城市用地演化与产业发展的关系及其量化指标,可供珠三角及其他城市群作参比。更多还原

【Abstract】 Urban industry realizes in the interaction process of urban industrial restructuring and the urban land evolution. Urban industrial structure transformation is a change process from quantitative to qualitative, while the development of urban land morphology and layout is relatively lagging behind. Thus, in order to provide the spatial support to industrial structure transformation, must explore the internal connection and evolution regularity with industry and land resource structure, which can optimize the land configuration and then adjust the urban land structure in advance.In this paper, ShenGuanHui Economic Circle is the study area. Based on the remote sensing data from Landsat TM/ETM and SPOT5 remote sensing image in 1990,1999,2005 and 2008and statistical data, extracted the land use information and socio-economic statistical information in Shenzhen Dongguan and Huizhou. Through quantitative evaluated the urban expansion rate and intensity, the information entropy, urban compactness and grid autocorrelation coefficient of the cities, comparatively analyses the evolution process of ShenGuanHui Economic Circle during the 18 years. Then, from industrial development stage, land economic density and the decoupling relationship of cultivated land occupation and economic growth, analyzed the relationship between the urban land evolution and industrial development. The results indicated: from 1990 to 1999, is the fastest expansion stage in Shenzhen and Dongguan, the land information entropy both achieved the peak in 1999. In Shenzhen, the urban land formed into ribbon development structure, city compactness leaped onto the more compactness stage, whereas Dongguan had the problems of "low, small and scattered". The region of grid autocorrelation coefficient≥4 level in 1999, Shenzhen was accounted for 80%, Dongguan was only 29%, while Huizhou was 34%.Due to the drive of significant project and orderly planning, Huizhou has formed into block pattern and positive development trend. Form 1999 to 2005, the land information entropy decreased in Shenzhen and Dongguan, indicated the construction land occupied the dominant position and all developed toward the direction of“urbanization completely”.Dongguan formed the pattern of“from line linking up into a stretch”, urban compactness also entered into the more compactness stage, the region of grid autocorrelation coefficient≥4 level was increased to 72%. With the implementation of the "double shift" strategy since 2005, industrial development shows“blossom everywhere”situation in Huizhou, urban compactness tended to loose. The region of grid autocorrelation coefficient≥4 level declined from 55% in the previous stage to 48%. Owing to the urban morphology fragmentary in Dongguan in a certain period, leaded to the land economic density was lower than Shenzhen and Huizhou for a long time, it increased steadily until with the urban land shape’s accumulation in 2004. The minimum value of decoupling rate in cultivated land occupation and economic growth separately in 1998, 2002 and 2005, all appeared in the industrialization later period, the second industry’s proportion surpasses 50%, the tertiary industry proportion surpasses 30%, in the second industrial interior light industry and the heavy industry proportion is relatively balanced. But the urban land morphology fragmentary dead to the decoupling relationship was instability, and with the relative decoupling primarily. In ShenGuanHui Economic Circle, Dongguan’s development path and the direction, also made great strides toward“Shenzhen pattern”, Shenzhen played a demonstration and leading role to Dongguan and Huizhou. The integration of ShenGuanHui Economic Circle will help alleviate capacity limitation. but must pay attention to prevent the industrial isomorphism tendency. The relationship and the quantitative indicators which the urban land evolution and industrial development revealed, may make a reference to Pearl River Delta and other urban clusters.更多还原
