基于全球500强在华投资数据,研究了汽车产业跨国公司在华功能区位。随着汽车产业跨国公司在华功能不断拓展,不同功能的空间分离已非常明显;服务功能主要集中在北京、上海,而生产功能则对上海、天津、重庆、广州等城市具有更强的偏好。条件逻辑模型的研究结果表明,集聚经济和制度约束是影响汽车产业跨国公司在华不同功能区位选择的重要因素...     

全息位置地图研究

位置信息服务是当代社会发展的一个重要方向,以位置为基础,将相关信息关联和分析,为潜在用户提供知识层次关于表达对象的全方位的信息,实现地理位置概念应用的飞跃。本文在地理位置与位置地图概念分析的基础上,进一步论述了语义位置、位置感知与位置计算的内涵,提出了全息位置地图的新概念,探讨了全息位置地图的主要研究内容和发展方向。     

厦门台企空间分布及区位选择分析

厦门是台商投资大陆最早和影响较大的城市之一.通过对厦门1 016条台企及其类型统计,并计算其地理集中指数;结合调查问卷和GIS技术,进行台企空间特征和台商投资厦门区位分析.研究结果表明:厦门的台企在空间分布上呈现岛内密集并逐渐向岛外迁移的趋势;在产业类型上以制造业为主,但其地理集中指数低于服务业;从台商投资区位选择角度分析,影响厦门台企分布的主要区位因子是市场、政策和环境,但近年来也面临着地区竞争和其他诸多不确定因素的制约,使得台企向厦门周边和其他地区迁移.     

基于位置感知设备的人类移动研究综述

每个人在地理空间内的移动看似随机而没有规律,然而一个较大规模人群的移动却隐藏着特定的模式。为了研究某些地理问题,如交通、疾病传播等,可以从个体行为出发,在地理信息系统的支持下,发现人类移动模式,并构筑基于个体的模拟模型,从而建立微观和宏观之间的桥梁,并支持相应的决策过程。信息通讯技术的发展,一方面改变了人们的空间行为模式,另一方面使得基于位置感知设备获取海量人类移动数据成为可能。近年来,上述研究一直是地理信息科学及相关领域的热点,该文对此进行了总结和评述。     

多粒度的人群移动模拟通用模型及其应用

人群的移动模拟应用广泛,但为不同时空尺度模拟需求开发不同的模拟系统十分困难和繁琐。该文设计了一种人群的空间移动模型(GMPM),GMPM具有多粒度特性,可应用于不同的领域,满足不同空间尺度、时间尺度的人群移动模拟需求;同时,GMPM又是一种通用开发模型原型,基于GMPM可以构造针对不同应用领域的人群空间移动模拟模型。最后,介绍了不同时空尺度人群移动模拟应用案例。     

城市实时交通监测中关键路口的选择

本文利用图论中的顶点覆盖算法和GIS中的网络分析技术，对非嵌入式传感器在路网中的最优定位问题，即关键路口点的选择问题进行了探讨。其目的在于选择最少的路口点而覆盖最大的路网范围，从而最大限度地掌握交通流在路网上的分布和变化。由于顶点覆盖是一个NP完全问题，本文将采用一个启发式算法，并在一个模拟的路网结构上进行解算。     

An analysis on location factors affecting the spatial distribution of Shanghai land values

With a technique of GIS(Geographical Information System) and a method of multiple linear regression analysis, the spatial distribution of Shanghai land values and its relationship with some location factors are examined in this paper. The database of land values consists of 166 land parcels leased during 1993–1994. The land value map shows that the spatial distribution of Shanghai land values has some distinct spatial features. Firstly, the highest land value areas are located along Nanjing Road, Huaihai Road and the Bund. Secondly, there is no conspicuous peak land value intersection within the CBD(Central Business District). Finally, The land values of Pudong are much lower than those of Puxi. The regression model between Shanghai land values and the selected location factors shows that Nanjing Road is the first important location factor affecting the spatial distribution of the land values, the city center is the second one and Huaihai Road is the third one. The Bund, the regional shopping centers and the transportation nodes have little influence on the land values. This relationship between Shanghai land values and the location factors is determined by the distribution of commercial activities, the characteristics of the CBD and the spatial form of the city.
