书法景观的文化地理浅释

书法地理学作为一门新兴的文化地理学的分支,它的基本理论研究对象之一便是书法景观。从文化地理学的角度出发,探讨了书法景观的概念,书法景观的分类。指出其构成除了自然因素以外,还应包括人文景观中的可视性因素、可悟性因素和氛围。书法景观是自然景观人文景观的统一体。     

浅析数字摄影测量在1∶500地形图测绘中的应用

数字摄影测量,应用计算机技术、数字影像处理、影像匹配、模式识别等理论与方法,以计算机视觉代替人眼的立体观测,其产品与中间数据的记录以及处理的原始资料均是数字的,较之常规的(传统的)数字产品的生产方法,具有自动化程度高、速度快、成果多样化等优点。两次外业和两次内业,是∶地形图数字摄影测量的主要作业流程,第二次外业调绘作为1500数字摄影测量的主要外业工作与常规调绘方法有一定的区别。∶地形图数字摄影测量适合于1500大面积数字化测图。

European capital cities as political frontiers

The capital is the centre of the established order but it always had to accept a relatively uncontrollable world of individuals redefining urban space in their own way or pioneering new means of support. As their existence is both a political nuisance and a foreshadowing of institutional changes (sometimes revolutionary) of nation-wide importance, I call such ways of life political frontiers. One may wonder what will become of political frontiers in the information society (or postmodern society) that, apart from borderless, has been described as society without a centre as well. Actually information society is the prototype of a frontier society with self-responsible groups and individuals. However, capitals – even stripped of their governmental functions – may offer a symbolical environment (a condensation of space and time) that precisely satisfies the wants of those who wish to politicise a way of life. Niches for pioneering behaviour may get dispersed over a wider territory but new types of political activity will gravitate to the capital even if the capital's official political status has dwindled.

文中论述和分析了网格、空间信息网格和地图上的格网等概念。在分析目前WebGIS的主要关键技术及实际功能和效果的基础上,从软件和数据两个方面分析了目前WebGIS存在的问题及其原因。针对目前WebGIS对于网格技术的不适应性,提出了关于基于多智能代理的网格地理信息系统的思考,论述了代理、移动代理和智能代理及其优势,给出了系统的体系结构,并对系统客户端、服务器及其智能代理技术进行了说明,研究了系统中移动代理的设计、迁移机制、巡回路线规划和通信机制等。最后给出了初步的结论和讨论意见。     

数字城市地理空间信息公共平台的设计

数字城市建设的目的是实现城市各种信息的数字化共享,地理空间信息是数字城市建设的基础信息,如何实现数字城市地理空间信息的共享是数字城市建设过程中的基本问题。在以往的数字城市建设中,地理信息往往作为城市某些职能部门的“私有”信息,其共享性得不到保证,严重影响了数字城市建设。地理空间信息公共平台的设计目的是实现地理信息共享。阐述的公共平台的系统设计主要分为公共基础空间数据库的建立、地理空间信息共享环境的设计以及地理空间信息公共技术平台设计3个方面的内容。

A Network Model for Dispersion of Communicable Diseases

The spread of communicable diseases through a population is an intrinsic spatial and temporal process. This paper presents an individual‐based analytical framework for modeling the spatial and temporal heterogeneity in the disease transmission. The framework specifies a network model structure and six associated parameters. These parameters describe the properties of nodes, the properties of links, and the topology of the network. Through this model structure and associated parameters, this framework allows the representation of discrete individuals, individualized interactions, and interaction patterns in a network of human contact. The explicit representation of the spatial distribution and mobility of individuals in particular facilitates the modeling of spatial heterogeneity in the disease transmission.     

A multi-equation spatial econometric model,with application to EU manufacturing productivity growth

A multi-equation spatial econometric model is used to explain variations across EU regions in manufacturing productivity growth based on recent theoretical developments in urban economics and economic geography. The paper shows that temporal and spatial parameter homogeneity is an unrealistic assumption, contrary to what is typically assumed in the literature. Constraints are imposed on parameters across time periods and between core and peripheral regions of the EU, with the significant loss of fit providing overwhelming evidence of parameter heterogeneity, although the final model does highlight increasing returns to scale, which is a central feature of contemporary theory.
