The author, comparing growth histories of East and West Siberian cities of over 50,000 population through regression and cluster analysis techniques, develops a number of city typologies based on magnitude of population growth, economic specialization, and social infrastructure. It is argued that such typologies are useful in planning because they identify types of cities experiencing similar growth conditions and instances where cities have changed from one type of situation to another. Although the study is limited to 1926-1986, it addresses economic and social components of Siberian urban growth relevant to the interpretation of preliminary results of the 1989 census (translated by H. L. Haslett, Leamington Spa, UK).  相似文献

中部地区典型煤炭城市接续产业响应模式分析及比较   总被引:1,自引:0,他引:1  
在煤炭城市转型的基础上采取适宜的转型路径和适当的响应模式,是煤炭城市实现可持续发展的必须条件。本文基于产业生命周期发展理论,在确定中部地区典型煤炭城市接续产业的前提下,利用SOFM模型,将中部地区典型煤炭城市发展接续产业响应模式进行了系统分类,并确定了具体的四类响应模式及相应阶段的特征,最后针对城市煤炭城市接续产业响应模式提出了相应的政策建议。  相似文献

中部地区城乡收入两极分化程度分析及其时空特征变化   总被引:1,自引:0,他引:1  
陈斐  俞彤晖  王海萍 《人文地理》2012,27(5):104-109
ER型指数测算表明,中部地区88个地市(州)城乡居民收入两极分化程度存在明显的时空变化和地区分异;根据2000年、2009年各地市ER指数值,分别将88个地市分为四大类型区,根据2000-2009年各地市ER指数值的变化情况,将88个地市又分为三类地市,综合分析2000-2009年中部地区城乡收入两极分化程度的时空特征变化。分析结果显示:2000-2009年,中部地区城乡收入两极分化程度越来越严重,绝大多数地市的城乡收入极化程度变化呈现出加速上升或一般化上升趋势,各省城乡居民收入两极分化程度也有很大差别;城乡收入极化程度各类型区的空间分布情况发生了明显的变化,各省收入极化程度变化不同类型区的分布存在明显的差异。  相似文献

In Tibetan areas, prior to the Democratic Reform (1959-1960), there were over 2,700 monasteries, and the population of monks and nuns totaled about 110,000, accounting for 10 percent of the total Tibetan population (1.2 million).  相似文献

This paper examines the role of urban social movements in shaping the built environment. It is based on empirical work undertaken in two relatively small towns, Darwin and Alice Springs, located in the Northern Territory of Australia. This approach has furnished the opportunity to undertake a true comparative study of the role of social movements in what ostensibly appear to be relatively simple urban locations situated in similar local, national and global circumstances, across the same time-period. In particular, the investigation sets out to examine the contrasting success/failure of social movements to coalesce around the problem of housing provision. The early sections of the paper review various conceptual issues related to the empirical investigation and try to arrive at a usable definition of ‘urban social movement’.  相似文献

ABSTRACT. We propose a mixed fixed and random coefficients framework for regional modeling. The framework allows the presence of both the region-specific effects and commonality of responses across regions. Bayes solutions for estimating parameters of interest and for generating predictions are derived. Within a Bayesian framework a predictive density approach to evaluate the impact of changes is suggested. We apply the methodology to evaluate the impact of new rate structures on Ontario regional demand for electricity.  相似文献

空间溢出对产业集群形成发展具有重要意义。但空间溢出对生产性服务业集群的影响机制并不清楚。本文基于1 km×1 km网格和2013年广州市中心区--天河区的企业经济普查数据,采用空间数据分析技术,识别生产性服务业集群,分析集群特征,探测集群溢出类型。结果发现:①生产性服务业集群区位指向大城市中心区的核心地域,具有五种集群类型分异,空间呈不完全耦合。②生产性服务业集群空间规模受Jocobs型和MAR型两种溢出调控,在MAR型溢出作用下的集群空间规模相对较小。③信息服务业集群的溢出为负效应说明溢出作为一种潜在利益,在转化为集群优势的过程中存在过滤效应。  相似文献

华北平原农村居民点演变及社会经济影响因素分析   总被引:8,自引:0,他引:8  
杨勇  邓祥征  吴锋  陈彤 《人文地理》2019,34(2):116-124
基于遥感图像分类解译数据,利用位序-规模模型、洛伦兹曲线、景观指数,定量识别了2000-2015年华北平原农村居民点空间分布、规模与形态演变特征,分析了社会经济因素的驱动机制。结果表明:华北平原农村居民点南-北方向呈显著的空间分异与集聚特征,密度分布呈现南密北疏的态势,与面积规模分布存在局域负相关;农村居民点景观指数显示出密度增大、形状更加规则、斑块面积差异增大、斑块间邻近距离不断缩短的变化特征;总人口数量和乡村户数等对农村居民点用地扩张具有促进作用,乡村常住人口、乡村从业人员数量等的作用为负。  相似文献

This paper presents the body analyses of 70 sherds of ceramics made in north China during the Late Tang and Northern Song dynasties (c. AD 80–1200). The major types represented are Ding, Xing and Cizhou-type wares. The analyses were obtained by atomic absorption spectrometry, giving information on nine major and minor constituents. These have been used to differentiate chemically between the major kiln sites in the north, with the aid of multivariate computer analysis. This has demonstrated that there are differing chemical characteristics associated with these kilns, but the study is hampered by the lack of authentic material from controlled excavations of the kiln sites.  相似文献
