再论中国城市的职能分类

在回顾中国城市职能分类的研究,总结前人工作的经验和教训的基础上,首次采用城市劳动力结构资料,得出比较符合实际的、能与国际接轨的全国综合性城市职能分类。将1990年465个城市分为4个大类、14个职能亚类和47个职能组,同时对城市职能分类的若干理论和方法论进行阐述,分类结果有广泛的认识价值和应用价值。     

珠江三角洲中小城市大气环境规划初探

分析中小城市大气环境规划的特点，采用总量控制和总量控制指导下的Ａ－Ｐ值法研究广东顺德市大气环境规划问题：用总量控制Ａ值法从宏观上控制区域总允许排放量，再用Ｐ值法控制每个单源的排放，通过影响系数研究工业区的布局方案，从而给出顺德市区域大气污染物允许排放量的典型分析和最大允许排放量的合理布局规划，指导未来污染源的选址、排放高度和排放量的确定。     

我国资源型城市产业转型的环境学思考——以甘肃省金昌市为例

 我国资源型城市的环境问题普遍比一般城市严重.在实现城市和产业转型的过程中，必须将环境问题纳入其转型战略中。本文以甘肃省“镍都”金昌市为例，分析了资源型城市产业转型中的环境制约因素，转型战略中应关注的环境保护和生态恢复等问题，提出了金昌市在产业转型中可以采取的缓解环境危机、生态恢复和循环经济的措施。     

Influence of seismicity parameter uncertainty on seismic hazard estimation of cities and towns

Introduction In his Doctor thesis, PAN (2000) has roughly studied some about the influence of parameter uncertainty on seismic hazard analysis. The aim of this paper is especially to study the uncertainty influence extent of seismic hazard analysis result in a spot, owing to the uncertainty of seismicity parameters induced by variational statistical time ranges of various statistical regions in the whole country. The authors have inquired into the uncertain extents of influence of seismic p…

Seismogenic Origin of the Ancient Avdat Ruins,Negev Desert,Israel

The present communication addresses the potential use of damage features, observed in the ancient ruins of the Avdat archeological site (Negev Desert, Israel) as a tool to identify the seismic origin of the destruction there and roughly to determine the direction of seismic wave propagation. This revised version was published online in June 2006 with corrections to the Cover Date.     

The changing distribution of incomes in Dutch cities: myth and reality

Segregation is a central concept in the debate on urban issues, both in scientific literature and in society in general. The process of globalisation is particularly expected to increase polarisation and segregation in cities, resulting in the emergence of ‘ghettos’ or – as they are called in the Netherlands – ‘income neighbourhoods’. This paper tries to judge the situation in Dutch cities by studying changes over time; by looking at segregation within cities as well as between cities and the wider metropolitan area; and by comparing socio-economic differences with socio-cultural and socio-demographic characteristics. The analysis shows that the empirical facts are quite different from the ongoing debate. It establishes that socio-economic segregation is more moderate than segregation with respect to the other two dimensions. Contrary to suggestions from the vernacular debate, segregation within cities is scarcely increasing, but between cities and the surrounding area it is rising with respect to all three dimensions.
