The Integration of Cooperation Model and Genetic Algorithm     

ZHENGZhaobao 《地球空间信息科学学报》2002,5(1):1-6

In the photogrammetry,some researchers have applied genetic algorithms in aerial image texture classification and reducing hyper-spectrum remote sensing data.Genetic algorithm can rapidly find the solutions which are close to the optimal solution.But it is not easy to find the optimal solution.In order to solve the problem,a cooperative evolution idea integrating genetic algorithm and ant colony algorithm is presented in this paper.On the basis of the advantages of ant colony algorithm,this paper proposes the method integrating genetic algorithms and ant colony algorithm to overcome the drawback of genetic algorithms.Moreover,the paper takes designing texture classification masks of aerial images as an example to illustrate the integration theory and procedures.  相似文献

刘振兴 《地球物理学报》2001,44(4):573-580

地球空间双星探测计划包括两颗小卫星,将分别运行于目前国际上地球空间探测卫星尚未覆盖的近地赤道区和近地极区.双星计划的主要科学目标是用高分辨率的仪器在近地空间的主要活动区探测场和粒子的时空变化;研究磁层亚暴、磁暴和磁层粒子暴的触发机制及磁层空间暴对太阳活动和行星际扰动的响应过程;建立地球空间环境的动态模式.为了实现科学目标,赤道卫星和极区卫星上各载有9台探测仪器.赤道卫星的轨道是:近地点550km,远地点60000km,倾角约2.5°;极区卫星轨道是:近地点350km,远地点25000km,倾角约90°左右.为了使双星计划与欧空局ClusterⅡ相配合,赤道卫星计划于2002年12月发射,极区卫星计划于2003年6月发射.双星计划与ClusterⅡ相配合,可形成地球空间6点探测计划,这将成为21世纪初国际上重要的地球空间探测计划.  相似文献   

Planning issues in the territorial integration of the Korean peninsula     

Won Bae Kim 《GeoJournal》2001,53(1):47-56

The historic summit between the leaders of the two Koreas in June 2000 provided a new opportunity for inter-Korean dialogue. Despite many uncertainties regarding the form and substance of inter-Korean economic cooperation, Korean people believe that inter-Korean economic cooperation will expand and eventually lead to economic and territorial integration of the two Koreas. This essay discusses the progress and issues of inter-Korean economic cooperation including infrastructure development. In particular, the essay examines long-term planning issues surrounding the territorial integration of the Korean peninsula and their implications for balanced development. With the German case of economic integration as a point of reference, the essay points out a few strategic problems involved in inter-Korean economic cooperation and suggests an alternative strategy to achieve balanced development.  相似文献   

90年代我国区域经济合作政策效果分析   总被引：18，自引：5，他引：13  

庞效民 《地理研究》1999,18(3):231-240

通过对90年代以来我国区域经济合作的具体实践进行总结和分析,论证分析我国推动地区经济技术合作政策的合理性和可行性。作者从明确中央政府和地方政府有关地区经济技术合作以及区域经济合作的政策目标出发,深入分析区域合作组织的合作动力机制及其实际进展,对区域经济合作取得的成果与当前区域合作中遇到的障碍和问题进行客观评价,并在此基础上提出有关政策建议。提出区域合作组织的发展只能对中央政府推动地区合作战略目标的实现作局部性贡献;总体而言,我国政府通过提倡地区经济技术合作来解决区域问题的国家地区协调发展战略目标的实现在一定阶段内缺少现实合理性。  相似文献

The Natural Hazards Theme of the International Year of Planet Earth     

Tom Beer 《Natural Hazards》2007,42(3):469-480

The United Nations has declared 2008 to be the International Year of Planet Earth. It is being organised under the auspices of the International Union of Geological Sciences and UNESCO. Planning for the International Year of Planet Earth has consisted of establishing 10 major science themes including Hazards. The Hazards Theme is centred around the following key questions: (1) How have humans altered the geosphere, the biosphere and the landscape, thereby creating long-term changes detrimental to life and the environment and triggering certain hazards, while increasing societal vulnerability to geophysical (geological and hydrometeorological) hazards? (2) What technologies and methodologies are required to assess the vulnerability of people and places to hazards and how might these be used at a variety of spatial scales? (3) How do geophysical hazards compare relative to each other regarding current capabilities for monitoring, prediction and mitigation and what can be done in the short-term to improve these capabilities (4) What barriers exist to the utilisation of risk and vulnerability information by governments (and other entities) for risk and vulnerability reduction policies and planning (including mitigation) from each of the geophysical hazards? Following the 26 December 2004 Indian Ocean Tsunami and the UN World Conference on Disaster Reduction held in Kobe, Japan in January 2005, the International Council for Science (ICSU) decided to establish a major research programme and initiative on Natural and Human Induced Environmental Hazards and Disasters that will co-operate with the Hazards theme of the International Year and continue through to 2011.  相似文献   

集团异化与亚太区域经济合作   总被引：2，自引：1，他引：1  

文云朝 《世界地理研究》1998,(1)

集团异化现象是集团化进程中的一种逆反行为,集中反映在经互会的解体和围绕“赫一伯法”而导致的北美集团成员国之间制裁与反制裁的公开对抗。冷战结束后这种现象异常活跃,而且具有广泛的世界意义。文章阐述了集团异化的概念和当代的集团异化现象和异化效应;分析了集团异化产生的国际背景与内因。作者进而指出,在新的国际形势下,集团异化构成为集团化进程中的一种新现象和新问题,并非偶然;最后探讨了它对于发展亚太区域经济合作的理论意义和现实意义。  相似文献

The economics of boldness: equity,action, and hope     

José Alberto Garibaldi 《Climate Policy》2014,14(1):82-101

Equity is usually interpreted in terms of the concept of justice, such that an equitable share of the atmospheric space is understood in terms of past emissions. This emphasizes the collective nature of sharing the burden of mitigation and the duty to act for those who have emitted the most. An alternative is considered: the aggregate costs and benefits to all Parties that could result from both increasing the level of collective ambition and implementing a climate regime that supports bold actions across all Parties. The regional impacts and carbon flow costs across differentiated scenarios are assessed and it is argued that the majority of developing-country Parties would be better off if a high ambition outcome to which all contributed, but some more than others. Moreover, those with middle or low emissions would have proportionally more to gain (or lose) relative to the level of ambition compared to those that have had higher emissions. The climate regime should be built on the principle of common but differentiated responsibility and respective capabilities (CBDR&RC), in which all act early even if some do much more; one that accounts for justice but does not forget hope.

Policy relevance

Differing interpretations of equity and the principles of the United Nations Framework Convention on Climate Change (UNFCCC) are discussed, with a focus on how these can enhance or hinder collective action. Whilst the climate change negotiations are usually taken as games in which one party gains and another loses, and interactions are dogged by continuous conflict, it is explored instead how negotiation responses can be framed in terms of cooperation. This would emphasize the gains that could be achieved by common but differentiated collective action, which could result in a collective avoidance of impacts. The possibilities that this shift of perspective could bring are explored by comparing costs under global cooperation (or lack of it). It is found that cooperation reduces the total costs for these regions. Thus, thinking in terms of cooperation focuses the options for negotiation on the means and interpretations of the UNFCCC principles that spur action and avoid climate impacts through collective action.  相似文献
