产业结构高度化对城市生产性空间的影响研究   总被引：1，自引：0，他引：1  

陈有川  孙博  尹宏玲 《地域研究与开发》2009,28(2)

以产业结构升级的主要途径--产业结构高度化为切入点,在分析产业结构高度化实现的两种方式,即产业结构横向高级化和产业结构纵向高级化的基础上,仅以空间经济为视角,运用阿隆索(W.Alonso)的竞标地租理论,分析了产业结构横向高级化、产业结构纵向高级化分别对城市工业和服务提供空间的影响,指出了城市生产性空间布局的演变有其内在规律性,以及违背产业发展规律而强行重组城市空间的危害性.只有根据产业结构高度化的实现方式并结合产业类型,有针对性地提供发展空间才有助于社会经济发展.  相似文献   

干旱区工业共生网络优化研究——以新疆石河子市为例   总被引：1，自引：0，他引：1  

冯琳  孙宝生 《干旱区地理》2009,32(6)

立足资源和环境约束,对干旱区工业共生过程中链条的设计、水资源的优化利用进行了定性探讨,提出两个观点:干旱区需在确定支柱产业和重点行业的基础上再进行纵向主导产业链与横向耦合共生链的设计;通过促进农业节水用于工业、工业共生反哺农业、提高工业重复用水率来解决工业用水不足的矛盾。继而运用模糊数学建立了多目标模糊优化模型,对共生网络的优化进行了定量研究。所建模型以共生网络经济效益、社会效益、资源效益和环境效益的综合最优作为目标函数,以非线性的相对优属度作为权重系数,将资源瓶颈、环境污染排放总量控制目标等作为约束条件,来求解多目标问题,既科学表达了共生系统的复杂性,又充分体现了工业共生追求经济-环境双赢的内涵。实例应用则表明以上思路、模型与方法具有理论价值和实践意义。  相似文献

经济危机背景下对我国专业化产业区的反思——重温意大利式产业区的价值     

王缉慈  刘譞 《地域研究与开发》2009,28(3)

在该文中,产业区是指从事同一生产过程不同阶段的生产和服务活动的专业化的中小企业组成特色的地方系统.在过去的10年中,我国专业化产业区和意大利式产业区的相似性已经被广泛关注.但是,我国的大量产业区因其非创新性的大批量制造而难以走出"低端道路"的困局,遭受经济危机的冲击.该文重温了意大利产业区模式.以新的视角探讨其核心价值,指出产业社区的文化根基以及持续创新的工业设计是其发展的动力源泉.在危机影响下变化的市场环境中,将大规模定制的生产模式引入产业区研究,并通过对比我国产业区与意大利式产业区,提出以设计为中心、加强技术创新与服务创新的产业区发展战略.  相似文献

基于耦合模型的中国能源生产与消费预测及其环境响应(英文)     

李强  任志远 《地理学报(英文版)》2012,22(1):93-109

The paper presents the prediction of total energy production and consumption in all provinces and autonomous regions as well as determination of the variation of gravity center of the energy production, consumption and total discharge of industrial waste water, gas and residue of China via the energy and environmental quality data from 1978 to 2009 in China by use of GM(1,1) model and gravity center model, based on which the paper also analyzes the dynamic variation in regional difference in energy production, consumption and environmental quality and their relationship. The results are shown as follows. 1) The gravity center of energy production is gradually moving southwestward and the entire movement track approxi-mates to linear variation, indicating that the difference of energy production between the east and west, south and north is narrowing to a certain extent, with the difference between the east and the west narrowing faster than that between the south and the north. 2) The gravity center of energy consumption is moving southwestward with perceptible fluctuation, of which the gravity center position from 2000 to 2005 was relatively stable, with slight annual position variation, indicating that the growth rates of all provinces and autonomous regions are basically the same. 3) The gravity center of the total discharge of industrial waste water, gas and residue is characterized by fluctuation in longitude and latitude to a certain degree. But, it shows a southwestward trend on the whole. 4) There are common ground and discrepancy in the variation track of the gravity center of the energy production & consumption of China, and the comparative analysis of the gravity center of them and that of total discharge of industrial waste water, gas and residue shows that the environmental quality level is closely associated with the energy production and consumption (especially the energy consumption), indicating that the environment cost in economy of energy is higher in China.  相似文献

It is essential to establish the water resources exploitation and utilization planning,which is mainly based on recognizing and forecasting the water consumed structure rationally and scientifically.During the past 30 years(1980-2009),mean annual precipitation and total water resource of Beijing have decreased by 6.89% and 31.37% compared with those perennial values,respectively,while total water consumption during the same period reached pinnacle historically.Accordingly,it is of great significance for the harmony between socio-economic development and environmental development.Based on analyzing total water consumption,agricultural,industrial,domestic and environmental water consumption,and evolution of water consumed structure,further driving forces of evolution of total water consumption and water consumed structure are revealed systematically.Prediction and discussion are achieved for evolution of total water consumption,water consumed structure,and supply-demand situation of water resource in the near future of Beijing using Time Series Forecasting Method.The purpose of the endeavor of this paper is to provide scientific basis for the harmonious development between socio-economy and water resources,for the establishment of rational strategic planning of water resources,and for the social sustainable development of Beijing with scientific bases.  相似文献   

INDUSTRIAL HERITAGE AND PLACE IDENTITY IN SPAIN: FROM MONUMENTS TO LANDSCAPES*     

PAZ BENITO DEL POZO  PABLO ALONSO GONZÁLEZ 《Geographical review》2012,102(4):446-464

In Spain, the birth of interest in the nation's industrial heritage dates from the 1980s and occurred alongside the process of deindustrialization. Policies concerning derelict industrial sites have shifted gradually from destruction to preservation, rehabilitation, and enhancement, and industrial heritage enhancement projects are now widespread in the country. However, a clear mismatching has arisen between institutional and academic initiatives and local communities, which exhibit widespread disinterest in or even rejection of industrial remains. This problematic situation can be related to the utilization of industrial heritage as an economic resource without paying much attention to its connections with memory and identity. Also, the mismatching is due to a positivist approach to industrial heritage whereby the monument and the museum are prioritized. We argue that projects which consider industrial remains as part of cultural landscapes might shorten the gap between the institutional and economic side of industrial heritage and its identity‐building and popular facets.  相似文献
