以南京市“一主三副”住宅小区为研究单元,运用GIS中的渔网（Fishnet）分析和探索性空间数据分析（ESDA）对“一主三副”住宅租金的空间分布进行模拟和估计,并利用地理探测器模型从住宅小区的区位特征、建筑特征和邻里特征3个方面探究住宅租金空间分异的影响机制。结果表明：① 南京市住宅租金总体呈上升趋势,空间上表现出主城向副城递减的中心外围模式,住宅租金空间结构逐渐由单核向双核发展,且住宅租金存在显著的空间异质性;② 住宅租金呈现出明显的空间正相关性和区域集聚性,热点区自内城核心区至副城趋于弱化,冷热点空间格局呈圈层结构;③ 交通位势和中心位势是对一主三副住宅租金解释力最大的因素,商务配套、金融设施和住宅房龄的解释力次之,特征因素对主城副城租金的影响强度各异。     

FORMATION MECHANISM AND SPATIAL PATTERN OF URBAN AGGLOMERATION IN CENTRAL JILIN OF CHINA

1 INTRODUCTION Urban agglomeration researches originated from the concern about the city cluster in the developed areas of western countries. The modern researches have been extended to the specific areas. HALL (2001) summa- rized the generality and difference of urban metropoli- tans in Europe, and analyzed the spatial structure of dif- ferent areas. NAUDE and KRUGELL (2003) analyzed the spatial development of urban agglomeration in South Africa, and thought that the size of the p…     

基于历史卫星遥感影像对城区空间形态演变的研究——以山东省潍坊市为例

基于潍坊市近50年来历史遥感影像,通过人机结合的方式,对历史影像进行中心城区范围提取,并开展面积变化、扩张速度和扩张强度、紧凑度、分形维数、重心迁移等相关指数的统计分析,发现潍坊市中心城区扩张的历史演变规律。通过提取水系、道路等城市发展相关要素,分析对其历史变化情况进行专题分析,以此为城市发展和规划提供数据和决策支撑。研究发现,潍坊市中心城区的空间形态演变规律初期向东侧发展,与寒亭区、坊子区形成三角状星型结构。后发展形成东西一体相连的单中心城区结构,最终形成潍坊市中心城区东西、南北十字结构。

Daqing is a mining city that was set up on wetland by exploiting and processing petroleum.This paper points out that net-group urban system is the optimization mode for Daqing urban spatial structure through analyzing and appraising the present situation,characteristics,advantages and disadvantages of Daqing spatial structure.And the best way of optimizing Daqing urban spatial structure is to adopt sustainable development strategy,establish the coordinated grade structure of urban system,construct developed towns net system,prefect the function structure of the towns at all levels,make full use of resources and strengthen environmental protection.Spatial structure of Daqing must be according-ly adjusted in order to adapt to the transformation of future economy types and functions.Bsded on the foundation of keep-ing net group,the development should be from disperse to moderate centralization in order to give prominence to the multi-function of the central city.Constructing ruralizing city should be the future goal of Daqing City.     

武汉市中心城区住宅价格空间分布格局及其影响因素研究

利用网页爬虫技术从安居客网站抓取了武汉市中心城区2016年7月共3 188个小区的平均房价数据。运用GIS空间分析方法和GWR模型对武汉市中心城区房价空间分布模式及其影响因素进行探讨。研究发现武汉市中心城区的房价具有聚类分布特征;新盘房价与片区位置(汉口、武昌、汉阳)、环线位置(内环、二环、中环)、距湖泊距离、距商圈距离、小区附近学校个数显著相关;楚河汉街商圈对二手房房价的影响力度高于其他商圈,东湖和沙湖对二手房房价的影响效应也很显著。     

禹城市农村居民点空间分布模式和景观格局

以禹城市农村居民点为研究对象,基于禹城市2000和2017年遥感影像解译数据,综合运用GIS、景观生态学及统计学理论与方法,分析了2000年与2017年禹城市乡村聚落的景观格局指数和空间演变特征。结果表明:禹城市两个时期农村居民点在空间分布特征上存在显著差异,与2000年相比,2017年禹城市农村居民点分布更加聚集;从聚集程度来看,禹城市农村居民点聚集的态势不够显著,这与禹城市当地的自然环境有密切的关系;禹城市农村居民点总体用地规模和数量虽然在减少,但部分居民点用地规模增加明显,居民点有集聚发展的态势,同时禹城市农村居民点斑块形态由复杂化向规则化转变。     

基于位置签到数据的城市空间分析与可视化

微博签到是一种典型的基于位置的社交服务,反映出社交用户与城市公共空间的互动,海量的社交位置签到数据为城市研究提供了全新的视角。本文基于香港、深圳两个城市2014年1月至2015年1月时间段内的新浪微博签到数据,从签到数据空间特性、旅游热点分布和居民活动空间3个方面对城市空间进行了综合分析:空间相关性分析结果表明签到事件在城市空间的分布具有明显的聚集性,并根据空间扫描统计结果依次标识出签到事件高值聚集区;针对旅游类签到数据分析发现两城市旅游关注度的时间变化趋势一致且峰值与我国假期时间分布相吻合,旅游热点主要分布于城市中心地带;以签到事件的规模、强度和集聚程度作为居民活动的表征分析城市活动空间特征,结果表明居民活动的核心圈层受到传统行政区划影响但分布已初步呈现"多心开敞"的空间形态。     

近20年烟台主城区土地利用变化特征与驱动分析

以TM影像为基本数据源,结合土地利用现状图和土地详查数据,分析了烟台主城区1992年以来土地利用空间扩张特征与机制,以能够更好地对城市进行科学规划控制,促进城市经济协调发展。通过对1992年及2013年TM遥感影像进行处理分析,结合烟台市的社会经济统计数据,得出结论：烟台市1992年到2013年城市空间扩张向西面及沿海方向发展;城市建筑用地面积增加较多,耕地和水域面积则呈减小趋势。影响城市土地利用空间扩张的驱动因子主要是经济发展、人口增长、产业结构、交通发展及国家政策等,其中经济发展和人口增长是促进烟台城市土地利用空间扩张的主要因素。

Suburbanization and subcentering of population in Beijing metropolitan area: A nonparametric analysis

This study focuses on the suburbanization and subcentering of population and examines the nature of spatial restructuring in terms of the population distribution in the Beijing metropolitan area.Instead of the classic density function approach,we employ the nonparametric analysis to characterize the spatial pattern of population densities in the Beijing metropolitan area and identify the suburban subcenters.Our findings suggest that the population has spread with rapid urban growth in the Beijing metropolitan area,and the compact urban form has been replaced by a more dispersed polycentric spatial distribution.However,compared with the decentralization of western cities,the spatial extent of the decentralization of population in the Beijing metropolitan area is quite limited.The rapid growth of population in the near suburbs has expedited the sprawl of the central city,with a larger central agglomeration of population dominating the metropolitan area.In this sense,the spatial pattern of the Beijing metropolitan area is still characterized by the continuous compactness.However,our findings do provide the evidence that the city has been turning to a polycentric structure.We find significant population subcenters have emerged in the suburbs of Beijing since the 1980s.But the polycentricity emerged in the Beijing metropolitan area is very different by nature from that observed in Western cities.The subcenters emerged are adherent to the development scheme planned for the city,so it can be referred to as the so called ’planned polycentricity’.

基于夜光遥感和小区POI的住宅发展与经济增长的空间耦合研究

针对城市住宅业发展与其经济增长之间的单向或双向因果关系问题,有关学者利用宏观统计分析的方法得到了不同的结论。本文通过构建二者的时空数据集,在城市内部微观层面上剖析了二者的耦合联系及其空间差异性,以期在细尺度上解释二者之间的关系。本文选取郑州市作为研究区,提出了一种基于夜光遥感数据的GDP空间化估算方法,进而生成GDP时空数据集;基于住宅小区POI点数据对城市住宅进行空间密度估计,得到住宅小区的时空分布数据集;最后对GDP和住宅建设密度进行了空间互相关分析,探究住宅发展与经济增长像元尺度上的共变趋势。结果表明：与前人的宏观研究论断不同,耦合分析结果显示住宅业发展与经济增长之间的关系在城市内部具有空间差异性,两者既存在相互影响的区域,也存在无相关的区域;耦合协调关系极显著的区域约占两成,且主要位于市属区和县域中心区;耦合不显著和不相关的区域超过七成,大部分位于市属县域。     

Influencing factors for formation of urban and rural spatial structure in metropolis fringe area—Taking Shuangliu County of Chengdu in China as a case

With rapid urbanization process, the pace of urban sprawl has been quickened and most metropolises have experienced expansions in leaps and bounds in suburbanization, which has greatly changed the urban and rural spatial structure of the metropolis fringe area. In this paper, Shuangliu County is taken as a case, since it is a typical fringe area of Chengdu Metropolis. Based on Landsat TM images of Chengdu City and Shuangliu County obtained in 1985, 2000 and 2004, characteristics of urban and rural spatial structure in Shuangliu County were analyzed, such as core-periphery spatial structure and some obvious integration trends. Then the influencing factors for the formation of urban and rural spatial structure were identified, including some natural, social, economic and political factors. According to the discussion of this paper, Shuangliu County is undergoing a key transition and reform period. Its formation of urban and rural spatial structure was affected not only by such common factors as the location, natural background, industrial transition, migration, etc., but also by some unique factors such as city planning and policy guidance, which played an important role in accelerating its uneven spatial structure. The understanding of the role of the influencing factors would be useful for carrying out spatial management and development planning of metropolis fringe area.

World cities and international organizations: Political global-city status of Chinese cities

In this study, the authors use a political perspective to explore the relative global status of cities in China. Two questions are addressed. Firstly, by using international organizations as the subjects and quantitative analysis of the spatial distribution of their offices, the overall position of Chinese cities in the global distribution of international organizations is estimated. The results show that 22 Chi- nese cities are involved in international political affairs. Beijing, Shanghai and Guangzhou dominate these activities and have high po- litical global-city status. Secondly, through qualitative analysis of Guangzhou City, the authors explore how its status as a center for intemational organizations has been shaped in recent years. The locational decision-making process is analyzed and the factors are demonstrated at both national and city scales. The definition of international organizations as used in this study refers not only to those supranational bodies that have the ability to manage relations across states （such as the European Union）, but also those in- ter-governmental organizations （IGOs）, international non-governmental organizations （INGOs） and diplomatic representatives and delegations that today also manage and regulate relations between and among states.     

中国古典叙事文学的时空叙事数字模型研究——以《李娃传》为例

文学制图作为一种再现文学空间的文学地理研究方法,能将历时性叙事与共时性空间进行相互映射,但是过往的实践案例往往受限于单一的研究视角,忽略了二者内部的整体性互动关系及其与外部时空的联系。为了促使文本中的线性叙事与并置空间作为整体概念而服务于当代的文学制图实践活动,本文依据巴赫金文学时空体中的历史时空、文本时空和读者时空的概念提出了一个叙事时空数字模型,并以唐传奇小说《李娃传》为文学制图实践案例,可视化再现了这个以唐长安为中心的爱情故事。在融合了计算叙事和地理叙事研究路径的基础上,本文对叙事文本所蕴含的顺序的、多维的和背景性的信息,进行了语义提取、语义的时空循环映射和“时间—时空—空间”的叙事再现,从而呈现叙事的语言线性、体验性和意义性的特征。该模型以开放的和可对话的框架帮助当代人理解古典文学叙事及其地方性历史语境,同时将拓展从宏观、微观的角度以沉浸式方式对地方（place）进行叙事的潜力。
