热力景观在城市生态规划中的应用

本文在引入城市热力景观这一概念来综合反映城市生态环境的基础上,阐述了一种以城市热力景观为背景对城市进行规划的方法:利用生态廊道的传输作用、切割作用、防护作用,以廊道为纽带,以水、路、风、林等贯通性廊道对城市生态环境进行疏导,使生态效应由线向面扩展,用线网结构沟通,从而形成城市生态的优化机制。     

中部地区城市群空间范围界定

对中部地区城市群的认识,目前主要有三城市群说、四城市群说、五城市群说、六城市群说等几种观点,且中部地区各城市群的概念、空间范围差异很大。对中部地区城市群的空间特征进行科学分析,为合理布局城市群发展空间、优化城市群空间结构和形成中部崛起的城市群带动机制提供参考依据。

服务经济下北京城市空间结构的转型

城市空间结构是城市经济结构和城市社会结构的空间投影,城市经济结构的变化必然促进城市空间结构的转型。新中国成立后,几乎所有的中国城市都经历了由服务性城市向生产性城市的转型。改革开放以来,特别是1990年代的城市改革,使城市在区域中的中心功能地位得到强化,部分城市开始从生产性城市向服务性城市转型,服务经济快速增长,城市空间结构也经历了空间重组和功能转移。本研究运用北京市1949-2010年第三产业各部门增加值数据和主要时段第三产业用地空间布局状况,从产业链、产业支撑、产业融合和服务外包四种服务经济发展模式入手,分析了服务经济作为城市空间结构转型的内在机制和空间演化趋势。     

From Supply Chains to Supply Ecosystems: Implications for Strategic Sourcing Research and Practice

Traditionally, sourcing decisions such as what to buy and from whom to buy it were viewed as clerical in nature. Today, however, many executives view sourcing decisions as strategic and these decisions are being made from more prominent positions within firms. Indeed, over time more companies are embracing the concept of strategic sourcing—making acquisition decisions with the intent of creating value and achieving a competitive advantage. In this article, we introduce the Special Topic Forum articles on strategic sourcing and performance. Each offers important implications for strategic sourcing research and practice. An overall implication is that some traditional supply chains appear to be giving way to supply ecosystems, which represent a set of interdependent and coordinated organizations that share common adaptive challenges and that collectively shape the creation and nurturing of a sourcing base that contributes to competitive advantage and superior performance. We offer several theoretical perspectives that hold promise for explaining supply ecosystem functioning and outcomes. In terms of practice, firms need to adapt their strategic sourcing to this evolution or run the risk of being weakened.

Tree farms: Driving forces and regional patterns in the global expansion of forest plantations

People have planted trees in rural places with increasing frequency during the past two decades, but the circumstances in which they plant and the social forces inducing them to plant remain unclear. While forests that produce wood for industrial uses comprise an increasing number of the plantations, most of the growth has occurred in Asia where plantations that produce wood for local consumption remain important. Explanations for these trends take economic, political, and human ecological forms. Growth in urban and global markets for forest products, coupled with rural to urban migration, may spur the conversion of fields into tree farms. Government programs also stimulate tree planting. These programs occur frequently in nations with high population densities. Quantitative, cross-national analyses suggest that these forces combine in regionally distinctive ways to promote the expansion of forest plantations. In Africa and Asia plantations have expanded most rapidly in nations with densely populated rural districts, rural to urban migration, and government policies that promote tree planting. In the Americas and Oceania plantations have expanded rapidly in countries with relatively stable rural populations, low densities, and extensive tracts of land in pasture. If, as anticipated, the growing concern with global warming spurs further expansion in forest plantations in an effort to sequester carbon, questions about their social and ecological effects should become more pressing.
