The role of money in China’s urban production: the local property industry in Qujing,a fourth-tier city     

Thierry Theurillat 《Urban geography》2017,38(6):834-860

What has made the urbanization of capital possible in China since the late 1990s? A major strand of literature in urban geography has pointed out land as the main trigger of urbanization. Scholars have highlighted the empowerment of local governments and their subsequent role in implementing China’s national urbanization objectives because of substantial revenues from the commodification of land. Other scholars have looked beyond the supply side, emphasizing the role of demand in stimulating urban development in China. In terms of demand, the speculative rationale of urban households aided land and property development during the 2000s, when property became a main alternative financial asset. However, this still raises the question of how urban production is financed. Based on a case study of the fourth-tier city of Qujing, in Yunnan province, this article investigates the financing of urban production from the perspective of the development industry. For the time being, little is known about how these companies finance their operations.  相似文献   

Physical Properties and their Relationship to Texture and Consolidation Effects in Pliocene-Quaternary Sediments from Madeira Abyssal Plain     

D. Casas  G. Ercilla  J. Baraza  B. Coakley 《Marine Georesources & Geotechnology》2006,24(4):265-286

Multi-sensor core logger data and index properties were measured onboard the JOIDES resolution during ODP Leg 157 and compared with grain size distribution and carbonate contents measured in the on-shore laboratory. Cored sediments are similar in grain size, but very variable in carbonate content. Magnetic susceptibility clearly defines the volcanic turbidite layers, whereas GRAPE density and acoustic velocity help to define the coarser (silty) bases of some organic or calcareous turbidite layers. Index properties are mostly controlled by consolidation effects.  相似文献   

基于语义的多细节层次3维房产模型   总被引：5，自引：2，他引：3  

朱庆  胡明远 《测绘学报》2008,37(4):0-520

针对2维房产管理中的产权重叠、表达不完全和建筑物室内外一体化管理难题,在综合分析3维房产数据的对象类型及其应用特性的基础上,从概念层次提出了一种基于语义的多细节层次3维房产模型。该模型通过空间与产权的语义描述,对3维房产管理对象间的多细节层次关系进行一体化表达,特别是实现了对建筑物内部的房产空间关系表达,有利于明晰内部空间(户)的产权划分及各房产对象间的产权关联,为建立产权明晰与室内外综合管理的真3维房产应用提供了理论依据。  相似文献

阿尔金北缘大平沟韧-脆性变形带特征   总被引：3，自引：2，他引：1

大平沟韧-脆性变形带出露于紧邻阿尔金北缘断裂北侧的新太古界达格拉格布拉克群钾长片麻岩中,与阿尔金走滑断裂索尔库里段相距约50km。总体呈东西向展布,高角度向南倾斜,倾角65～85°。次级变形带呈北西西向-东西向波状起伏延伸。单个次级变形带规模一般长数百米,宽数十米。变形带内岩石的线理、面理构造发育,石英、钾长石矿物粒内变形效应明显,同构造变形的新生矿物绢云母比较发育。变形性质为韧-脆性压扭性构造变形,发育糜棱岩系列岩石,特别是含钾长石残斑的绢云母石英质糜棱岩最为常见。变形岩石组构显示石英以底面和近于底面滑移的方式发生变形,反映出是中-低温条件(250～350℃);有限应变测量显示岩石变形强度中等,应变椭球轴比为2.9～4.8;变形运动学特点为右行逆冲,变形主压应力方向为北北西向,最大差应力为59～61MPa。结合区域构造演化,作者认为该韧-脆性变形带是发生于早古生代板块碰撞的大地构造背景条件下,并反映了板块碰撞过程中基底岩块的变形特点。  相似文献   

三峡库区秭归县膨胀土研究     

张加桂  曲永新  余祖湛 《水文地质工程地质》2008,35(1):28-31

秭归县膨胀土是继在三峡库区巫山县、奉节县和兴山县发现膨胀土之后发现的又一处膨胀土,从而揭示了三峡库区膨胀土的地域性。秭归县膨胀土与三峡其他地方的膨胀土一样发育于特殊的地质环境内,具有坡洪积成因和较均一土体结构。土的膨胀性主要取决于其中的蒙脱石,测试表明有效蒙脱石含量达18.67%,以中等混层比的伊利石/蒙脱石(I/S)混层矿物形式存在。土具有高塑限、高液限和低抗剪强度。判别表明,它达到了国内外膨胀土标准和界限。  相似文献

3D Property Modeling of Void Ratio by Cokriging   总被引：2，自引：0，他引：2

Void ratio measures compactness of ground soil in geotechnical engineering. When samples are collected in certain area for mapping void ratios, other relevant types of properties such as water content may be also analyzed. To map the spatial distribution of void ratio in the area based on these types of point, observation data interpolation is often needed. Owing to the variance of sampling density along the horizontal and vertical directions, special consideration is required to handle anisotropy of estimator. 3D property modeling aims at predicting the overall distribution of property values from limited samples, and geostatistical method can he employed naturally here because they help to minimize the mean square error of estimation. To construct 3D property model of void ratio, cokriging was used considering its mutual correlation with water content, which is another important soil parameter. Moreover, K-D tree was adopted to organize the samples to accelerate neighbor query in 3D space during the above modeling process. At last, spatial configuration of void ratio distribution in an engineering body was modeled through 3D visualization, which provides important information for civil engineering purpose.  相似文献
