南京都市圈空间相互作用时空演变分析

利用改进引力模型并结合GIS 方法,分析2000 年以来南京都市圈县域尺度空间相互作用的时空演变,探讨圈域发展的问题与对策。结论如下：南京都市圈县市空间联系强度不断增强,南京主城与其它县市相互作用强度最高,其次为沿江各县市间、地级市主城区与其郊县间,南京、扬州、镇江、马鞍山等所辖县市间出现了联系强度较高的网络,有一体化发展趋势;历年县市潜力值都由最高峰的南京主城区为中心向四周递减,呈圈层式结构,在向外扩展过程中存在空间变异性,高潜力区沿江伸展,随着圈域内其它地区的发展,单一核心的结构开始发生变化;最后总结都市圈发展过程,提出圈域一体化发展的政策、交通、产业措施。     

北京城市空间认知的影响因素分析

城市空间认知影响因素分析与认知空间格局研究具有同等的重要性。论文基于北京城市空间认知调查问卷数据,引入居民属性等16个变量,利用二值Logistic回归方法,提炼出23个认知地点整体以及交通节点、商场、休闲地三种类型地点的认知影响因素。发现:第一,不同类型地点的认知率影响因素存在异同,其中,存在职住变更是最为显著的共性因子。第二,各类地点中的显著影响因子对认知率的作用大小有明显差异,年龄46-55岁变量是23地点认知率的最重要影响因素,交通节点和商场认知率最重要的影响因素为就业内城四区,而就业地与休闲地距离小于等于6km变量对休闲地认知率的影响最大。第三,各类模型中的影响因素类型不同且影响程度有很大差异,故具有不同属性信息组合的居民认知率不同。     

港口体系演化的影响因素及驱动机制分析

区域港口体系的结构和层次是不断变化的,根据各港口功能和作用的大小不同的变化,港口体系演化变现为集中化发展和分散化发展两种趋势。影响港口体系演化的因素很多,具体可归纳为技术进步因素、区位因素、航运市场因素、政策和政治因素四类。在集装箱革命之前,区位因素是影响港口体系结构的主要因素,而集装箱化之后,新技术的应用、航运市场在港口体系层次变化中的作用越来越明显。政策和政治因素是港口体系发展的背景因素,其影响力一直较大。最后通过构建港口体系动力模型,详细阐述了各个因素对港口体系演化的影响过程和驱动机制,分析了不同因素对于港口体系集中化和分散化发展的促进和阻碍作用。     

差异分权与多元碎化:大都市边缘地区城镇化空间模式研究——基于武汉市蔡甸区的实证

大都市边缘地区是大都市经济增长与空间拓展的主要地域,也是分权化治理最为复杂的区域。大都市边缘地区往往针对不同主体采取不同模式的分权化来调整其空间治理结构以适应发展需求。本文构建从分权化治理到城镇化空间的逻辑框架,从大都市边缘地区"差异分权"的空间治理格局入手,落脚在"多元碎化"的城镇化空间模式上,进而对从空间治理的"差异分权"到城镇化空间模式的"多元碎化"间的制度逻辑进行了解析,认为差异分权格局是当前大都市区边缘地区城镇化空间模式多元碎化的直接诱因,因此新型城镇化迫切需要从治理结构上予以破解。     

Sources and composition of fluids associated with fluorite deposits of Asturias (N Spain)

The fluorite deposits of Asturias (northern Iberian Peninsula) are hosted by rocks of Permo‐Triassic and Palaeozoic age. Fluid inclusions in ore and gangue minerals show homogenization temperatures from 80 to 170°C and the presence of two types of fluids: an H₂O–NaCl low‐salinity fluid (<8 eq. wt% NaCl) and an H₂O–NaCl–CaCl₂ fluid (7–13 wt% NaCl and 11–14 wt% CaCl₂). The low salinity and the Cl/Br and Na/Br ratios (Cl/Br_molar 100–700 and Na/Br_molar 20–700) are consistent with an evaporated sea water origin of this fluid. The other end‐member of the mixture was highly saline brine with high Cl/Br and Na/Br ratios (Cl/Br_molar 700–13 000 and Na/Br_molar 700–11 000) generated after dissolution of Triassic age evaporites. LA‐ICP‐MS analyses of fluid inclusions in fluorite reveal higher Zn, Pb and Ba contents in the high‐salinity fluids (160–500, 90–170, 320–480 p.p.m. respectively) than in the low‐salinity fluid (75–230, 25–150 and 100–300 p.p.m. respectively). The metal content of the fluids appears to decrease from E to W, from Berbes to La Collada and to Villabona. The source of F is probably related to leaching of volcanic rocks of Permian age. Brines circulated along faults into the Palaeozoic basement. Evaporated sea water was present in permeable rocks and faults along or above the unconformity between the Permo‐Triassic sediments and the Palaeozoic basement. Mineralization formed when the deep brines mixed with the surficial fluids in carbonates, breccias and fractures resulting in the formation of veins and stratabound bodies of fluorite, barite, calcite, dolomite and quartz and minor amounts of sulphides. Fluid movement and mineralization occurred between Late Triassic and Late Jurassic times, probably associated with rifting events related to the opening of the Atlantic Ocean. This model is also consistent with the geodynamic setting of other fluorite‐rich districts in Europe.     

Gender and emergent water governance: comparative overview of neoliberalized natures and gender dimensions of privatization,devolution and marketization

This article provides a critical reading of some of the gendered dimensions of emergent water governance regimes, specifically those related to the privatization, marketization and devolution of water resources management. After first providing an overview of recent nature–society contributions related to neoliberalization processes, the article comparatively evaluates insights with respect to the gender dimensions of recent shifts in water governance. I make several arguments at the intersection of relevant literatures. First, there is a need for gender theorists interested in water resources and nature–society debates to engage more with issues, theories and processes associated with neoliberalization. Second, there is a need for more attention to gender, feminist theory and approaches to inequality and socio-spatial difference in discussions of neoliberalized natures. Third, reading these literatures together reveals that there is a need to be self-reflexive and critical of elements of the gender and water literature that implicitly endorse foundational elements of the neoliberal turn in resource governance. Finally, there are particularities with respect to gender theory and politics, and water materialities that hold importance for understanding recent water governance shifts in the broader context of political and economic changes associated with neoliberalization.     

应对公共危机的法律规治初探

应对公共危机,法律虽然不是万能的,但法律的作用是不可替代的。对应急行政行为进行法律规治,既是依法行政的必然要求,也是由应急行政行为的特殊性所决定的。     

高斌《南河图说》与乾隆首次南巡研究

雍正年间黄河河政管理制度的变化,推动了清代黄河图绘制内容和机制的变化;而康熙年间张鹏翮所绘河渠水利图集的内容和形式,也影响了乾隆年间江南黄运河图集的编绘。海内外分别收藏有以江南黄河、运河、洪泽湖、淮河工程为主题的河渠水利图集一"南河图说",经考证均为乾隆十五年(1750年)江南河臣高斌、张师载等人在乾隆帝首次南巡的背景下绘制呈送的定本、副本或后人摹绘本。《南河图说》既是河督高斌反映河情、陈述治河政见、彰显治河政绩的工具,也是乾隆帝确定南巡路线、了解河务、进行河政决策的重要依据。《南河图说》的绘制、呈奏和运用在很大程度上确定了乾隆首次南巡的模式,对研究乾隆南巡和乾隆朝河政运作具有重要价值。     

Branded cities: outdoor advertising,urban governance,and the outdoor media landscape

Abstract: In many cities both rich and poor, new forms of outdoor advertising are emerging with potentially significant implications for the nature of the urban public realm. Public–private partnerships for advertising‐funded provision of basic items of urban infrastructure such as bus shelters, street signs and public telephones have grown as a result of structural changes in the advertising industry and shifts towards neoliberal forms of urban governance. This article critically interrogates the implications of these new outdoor advertising arrangements for the urban public realm, and argues that they have potentially harmful consequences for the accessibility and diversity of the outdoor media landscape. It then proposes three strategies for the democratisation of that landscape. These strategies are not premised on an outright rejection of outdoor advertising, but rather seek to contest the monopolistic capture of outdoor media by public–private partnerships involving urban authorities and outdoor advertising companies.     

“A World Class City of Your Own!”: Civic Governmentality in Chennai,India

Abstract: This paper utilizes a critical governmentality approach to theorize the processes through which urban elites become stakeholders in the “world‐class city”. Through a case study of public consultations for urban development plans in Chennai, India, the paper explores the technologies that produce urban actors who “participate” in urban governance. Key to these technologies is a discourse of participation that privileges and normalizes citizens as urban stakeholders. The paper contributes to current explorations into the technologies of inclusion that are central to an emerging civic governmentality in South Asia. In Chennai this civic governmentality engages various segments of civil society in processes of urban governance through the mechanism of public consultation. It is through these public consultations that elites come to exert influence over urban plans and consolidate a vision and desire for the world‐class city.
