中国与美国西部平均构造剪应力值的比较

提出了一种估计一个地区平均构造剪应力值的方法．用这种方法，选取哈佛大学公布的1977～1999年共15 993次地震的矩张量数据，估计了美国西部19个地区、中国和邻区43个地区(每个地区为1010范围)的平均环境剪应力值．结果表明，美国西部南加州西部海域和南加州应力最高，达13.7和12.0 MPa，然后向北、向南和向东逐渐递减，但最小也达8.7 MPa，是最高值的63%．中国新疆西北部地区和西藏察隅地区应力水平最高，达17.2和12.9 MPa，比美国高．中国的华北、云南、四川、台湾和美国南加州的应力水平差不多．中国南北地震带的应力水平为13 MPa左右，比南加州略高．两个重要地区的平均剪应力值分布图，提供了地学的基本数据．这些结果可为研究地震活动的大背景提供依据，对研究强地面运动参数(如峰值加速度及反应谱等)的衰减关系也是有用的．      

天津市地震经济损失模型和生命损失模型的预测研究

文中主要探讨了由地震引起的天津市经济损失和生命损失的预测问题。首先阐述了天津市震害预测的 5个背景特点 :建筑物特点、地质条件特点、建筑场地划分特点、基本设防烈度特点以及地震烈度衰减关系特点 ,根据这 5个特点将天津市划分为含有 7种建筑结构形式的 4个区域的震害预测模式。在此基础上 ,分析了天津市地震经济损失模型和生命损失模型 ,考虑了时间因素 ,然后与1976年唐山大地震的实际震害结果进行了对比及修正 ,给出了天津市 4个区域的建筑物地震经济损失率模型、社会财富损失率模型和建筑物毁坏率模型 ,并给出了计算天津市建筑物地震经济损失、天津市国内生产总值GDP地震经济损失和天津市地震生命损失的表达式 ;最后 ,将天津市地区划分为2 85 8个震害评估单元 ,以近百年来在天津市区域内曾经发生的最大地震作为假想地震 ,预测分析了天津市建筑物地震经济损失分布和地震生命损失分布结果     

新时期我国区域经济地理学发展问题初探

我国新时期的区域经济地理学在取得全面发展的同时，在理论体系，研究方法和实践领域等方面还需要进一步的发展，文章根据学习和实践区域经济地理学的体会，初步提出基础理论和应用理论，思维方法和技术方法等方面发展见解，并指出区域创新系统和国际经济技术合作等学科应注意拓展的重要实践领域，最后提出我国区域经济地理学科发展的建议。     

河南经济技术开发区发展前景与对策

文章阐述了经济技术开发区在区域经济发展过程中的作用。根据河南省经济技术开发区的发展现状和存在的问题，分析了加入WTO后开发区所面临的机遇和挑战，并在此基础上从开发区环境营造，运行机制，筹资方式，产业发展，城市建设等方面提出了加快河南省经济技术开发区发展的对策。     

新疆城市化与经济发展协调性分析

从新疆自20世纪80年代以来城市化水平与经济发展水平、产业结构的变化的吻合度或偏离度，来论述新疆的城市化水平是否与经济发展相协调，求证新疆城市化与经济发展水平之间的相关关系，并预测城市化率；剖析新疆城市化滞后于经济发展的原因，提出新疆正处于城市化由初期向快速发展期的过渡阶段，加快城市化的关键是推进工业化。     

远东热点:朝鲜半岛形势分析

朝鲜半岛独特的地理位置，无论对周边的中，俄，日三国，还是对大洋彼岸的美国都具有十分重要的地缘战略意义。如果说这里是四大国利益相互交错的唯一地区，那么解决朝鲜半岛问题便不仅取决于半岛内部北，南双方的互动关系，而且取决于四大四的立场及东北亚政治地理格局的演变态势。近年来随着朝鲜北，南双方首脑的成功会晤，朝鲜半岛的和平统一进程迈出了实质性步伐。但由于朝鲜半岛问题牵涉面广，影响因素复杂，从而使半岛的和平统一进程出现了一波三折的复杂局面，本文从政治地理学角度对半岛形势进行了分析。供关心朝鲜半岛局势的同仁参考。     

Pauperizing the pastoral periphery: the marginalization of herding communities in the world's dry lands

Environmental degradation and other socio-economic problems are too often discerned in contemporary pastoral systems in the wake of global economic change. This paper identifies cases where pastoral people respond to external pressures and opportunities in positive ways and adapt to changes. We hope that by doing this a framework of pastoral adaptations can be developed. The first part of this paper focuses on impacts of global economic change, which are mostly negative in nature. Through an extensive literature search in geography, anthropology, range management, and development field, the second part introduces cases that we categorize as positive adaptations.     

The Permeable City: Toronto's Spatial Shift at the Turn of the Millennium

This article presents an analysis of the relationship between urban governance restructuring, and global, national, and local action through a case study of the Toronto city‐region. The Toronto city‐region recently underwent a massive reorganization of its governance structures, functions, and jurisdictional boundaries. This restructuring raises questions about why these changes occurred at this particular juncture in the region's history. Why did the city that had always been known in the academic and political discourse as the “city that works” stop “working”? What global and national forces might have accounted for such a radical restructuring? And what did local action contribute? These questions are explored in both historical and contemporary contexts by drawing on insights from regulation theory, urban regime theory, and an analysis of Canada's changing fiscal federalism. This approach informs the role that institutions — regardless of their origin or territorial scope — play in sustaining a local accumulation system, and how this “local” accumulation grounds a national regulatory mode and regime of accumulation. The approach also explores the relationship between regime and regulation theories in the context of policy formation and institution building. The study concludes that the current policy set is incapable of resolving the region's crisis tendencies. Notwithstanding external forces, the current policy set is not inevitable. Globalization does not predetermine all spatial‐economic outcomes.
