Introduction At the end of last century, the Committee of International Decade for Natural Disaster Re-duction had called on evaluating the ability reducing earthquake disasters of cities. However, since efficient method to assess earthquake loss of cities does not exist, the proposition did not come true. In 1994, China government put forward that the cities with dense population or developed economy and the areas off the seashore should have the ability to resist earthquake (M=6). Un-dou…  相似文献   

Study on evaluation of cities’ ability reducing earthquake disasters

Cities’ ability reducing earthquake disasters is a complex system involving numerous factors, moreover the research on evaluating cities’ ability reducing earthquake disasters relates to multi-subject, such as earthquake science, social science, economical science and so on. In this paper, firstly, the conception of cities’ ability reducing earthquake disasters is presented, and the ability could be evaluated with three basic elements — the possible seismic casualty and economic loss during the future earthquakes that are likely to occur in the city and its surroundings and time required for recovery after earthquake; based upon these three basic elements, a framework, which consists of six main components, for evaluating city’s ability reducing earthquake disasters is proposed; then the statistical relations between the index system and the ratio of seismic casualty, the ratio of economic loss and recovery time are gained utilizing the cities’ prediction results of earthquake disasters which were made during the ninth five-year plan; at last, the method defining the comprehensive index of cities’ ability reducing earthquake disasters is presented. Thus the relatively comprehensive theory frame is set up. The frame can evaluate cities’ ability reducing earthquake disasters absolutely and quantitatively and consequently instruct the decision-making on reducing cities’ earthquake disasters loss.

当代俄罗斯经济区划研究   总被引：1，自引：0，他引：1  

王殿华 《世界地理研究》2004,13(3):37-42

前苏联是世界最早研究经济区并进行经济区划实践的国家。在当代俄罗斯市场经济的转型时期，其经济区划具有新的背景、结构和原则。随着俄罗斯集权化的巩固和联邦化的发展，如何在全国范围内合理布局生产力，改善联邦各主体原有的经济部门和地域结构，使不同水平的区域综合发展，并表现其鲜明的市场专业化水平，进行科学的经济区划是俄罗斯经济地理所面临的主要任务。本文通过对俄罗斯经济区划的历史回顾及现状分析，提出了其区域发展的现存问题及解决措施。  相似文献   

整合:我国城市群经济持续发展的战略性选择   总被引：7，自引：0，他引：7  

林先扬  陈忠暖 《世界地理研究》2004,13(3):50-57

城市群的存在是区域城市化与城市区域化的重要表现，它作为区域城市化高级阶级的现象，是集聚与扩散共同作用的产物。经济全球化与区域经济一体化必然要求重视和加强城市群经济的发展。我国城市群的发展壮大能极大地提升我国的国家竞争力，对我国经济持续稳定发展意义重大。本文在经济全球化，特别我国成功人世将进一步与世界经济体系接轨的发展背景下，展开探讨我国城市群经济整合机制及模式，寻求城市群的持续高效发展。  相似文献

THE POLITICAL ECONOMY OF FOREST POLICY IN MEXICO AND CHILE     

Eduardo Silva 《Singapore journal of tropical geography》2004,25(3):261-280

Widespread agreement exists on the broad outlines of the concept of sustainable development for developing countries. This calls for a development model capable of meeting basic needs without depleting natural resources at a rate that robs future generations of their use. In this regard, citizen participation is also considered key to legitimise such policy choices. However, there is considerable disagreement over the substance and meaning of the major components of the concept and the relationship between them. This paper argues that positions in policy disputes over the sustainable development of the forest cluster in two distinct approaches: market‐friendly initiatives and grassroots development. Since market economies prevail almost everywhere, the question that is posed concerns the conditions under which the grassroots development approach is included as a significant complement to market‐friendly initiatives. This is a political question, requiring an examination of actors, interests and power resources. The paper thus applies a political economy framework to a paired comparison of Mexico, where grassroots development approaches (community forestry) had notable successes, and Chile, where market‐friendly forest policy crowded out alternatives.  相似文献   

Integrated oil exploration decision systems     

John W. Harbaugh 《Mathematical Geology》1977,9(4):441-449

The fully integrated, analytical decision system can be developed for petroleum exploration. Such a system would use conditional probability estimates of wildcat drilling success, based on biologic variables. These probabilities can be combined with financial analyses to produce Assessments of optimum exploration strategies.This paper was presented at Symposium 116.3, Quantitative Strategy for Exploration, held as part of the 25th International Geological Congress, Sydney, Australia, August 1976.  相似文献   

典型工业化国家SO2排放影响因素分析及其对中国的启示          下载免费PDF全文

李瑞萍  王高尚  王安建  骆建华  耿诺 《地球学报》2010,31(5):749-758

通过美国100年来SO2排放趋势分析, 对比日本、英国的相关数据资料, 发现SO2的排放与能源消费、经济发展、环境政策以及环保技术进步密切相关: 经济结构的转变和能源结构的调整是SO2减排的关键因素, 环保政策和技术进步是SO2减排的主要驱动力。典型国家SO2排放强度曲线均呈倒“U”型, 符合环境库兹涅茨曲线。SO2排放的拐点美国在人均GDP15000美元, 日本和英国在人均GDP9000～10000美元; 三个国家人均SO2排放强度的拐点在人均GDP5000～7000美元, 目前中国已经越过人均SO2排放的顶点。在此基础上本文提出了中国进一步减排SO2的建议。  相似文献
