Land use patterns can be viewed as a reflection of various factors including zoning regulations and environmental and social influences. To understand the effects of these factors, late twentieth century land use data for Kamakura City, Japan were analysed in relation to zoning regulations and geomorphological influences using geographic information systems techniques. Kamakura is a typical example of an Asian historic city experiencing the pressures of recent urbanisation. Statistical analyses, including principal component analysis, were employed to identify factors affecting changes in major land use patterns over time and space. The rapid increase in population and government regulation in the 1970s led to the construction of low-rise buildings in piedmont areas. However, topography and conservation activities limited construction to areas with slope angles below about 10°. In the late 1980s and early 1990s, the area of vacant land on the urban lowlands increased due to the large increases in land value during the Japanese Bubble Economy phase. Land use intensified in most urban areas, although hilly areas were still characterised by low-rise buildings. Although urban sprawl has occurred in many cities in Asia, this has been limited in Kamakura because of strong land use regulation and conservation activities. However, the city has experienced high-rise development in its urban lowlands. 相似文献

武汉都市圈经济联系时空演变特征分析 总被引:16,自引:0,他引:16
城市化、信息化、工业化进程的不断加速,城市群体化现象的大量涌现,使得以特大城市为核心的都市圈经济联系及其复杂性成为当前地理学研究的前沿与中心。基于经济联系发展与空间结构演替的共轭关系,通过相关统计资料统计分析,从城市化、交通化、工业化、信息化、服务产业化五方面归纳了建国来武汉都市圈经济联系的发展历程:波动发展阶段(1949-1965年)、停滞不前阶段(1966-1978年)、快速发展阶段(1979-1989年)、全面发展阶段(1990年至今);从经济联系作用的交通扩展与功能集散角度分析了武汉都市圈地域结构形态演变特征,揭示出武汉都市圈经济联系空间结构在城市扩展方向上呈现孤立-向心-离心-圈状-轴向变化,在空间形态上则表现为块状-星状-组群-圈状-带状演替,并对其未来高级形态--中部都市带发展提出空间组织构想。 相似文献

上海市传统产业的地域转移研究--基于国际大都市建设的新思路 总被引:3,自引:1,他引:2
国际大都市的产业结构特征与上海市传统产业结构的现实,决定了上海市建设国际大都市目标的实现有赖于传统产业顺利实现地域转移。根据传统产业的区域转移理论和区位进入理论的Hayter模型,在全球生产一体化和中国进入开放经济发展新阶段的背景下,上海市传统产业的地域转移有两种空间取向:国内转移和国际扩张。国内转移有扩展转移和等级扩散两种途径,移出产业的选择要依据上海产业重构的要求和产业优势状况确定。国际扩张是对外开放新阶段的重大举措,根据上海的实际,提出三种国际空间扩张策略和境外投资的区域多元化战略。 相似文献
