21层大气环流模式IAP AGCM-III的设计及气候数值模拟I.动力框架     

左瑞亭  张铭  张东凌  王爱慧  曾庆存 《大气科学》2004,(5)

设计了IAP (InstituteofAtmosphericPhysics,ChineseAcademyofSciences)AGCM III,对其动力框架作说明和检验 ,时间积分采用改进的非线性迭代法。用Rossby Haurwitz波对框架进行了波型检验、能量检验和波速检验。结果表明 ,非线性迭代 3次的时间积分方案具有较好的稳定性 ,能够有效地抑制短波 ,同时对长波的歪曲较小 ,且时间积分步长可放得较大 ;该框架能够较长时间地保持Rossby Haurwitz 4波波型 ,在积分过程中能够较高精度地保持总有效能量守恒 ;模式计算的Rossby Haurwitz波速为每天西传 1 5个经度 ,这与理伦值很接近。  相似文献

Integrating Environmental Education Into Business Schools' Educational Plans in Finland     

Liisa Rohweder 《GeoJournal》2004,60(2):175-181

Environmental education in business school context has a significant effect on the way companies view environmental problems. Business schools train the future decision makers who can, with their own attitudes and practical actions, influence the contribution of business to the process of ecologically sustainable development. However, several studies show that no systematic thinking has been undertaken within business education as to what the educational prerequisites of the process of ecologically sustainable development are. In this article, I will firstly analyze by means of environmental education how business polytechnics in Finland have taken into consideration ecologically sustainable development. Secondly, I will raise the starting points for the development of the implementation of environmental education as part of the business schools▪ educational plans. Integrating environmental education into the vocational courses is identified as being one of the most effective ways of increasing the effectiveness of environmental education. Thirdly, the emphasis is on identification of barriers of integrating environmental education into the educational plans of business polytechnics. Theoretically, the article is attached to the objectives and learning concepts of environmental education and to educational planning theory in general. The empirical data are based on interviews I conducted 1999–2000 in all Finnish polytechnics offering business education. My article increases theoretical and practical understanding of how environmental education should be implemented in business education and how the current situation could be developed.

Researching the South African tourism and development nexus   总被引：1，自引：0，他引：1  

Gustav Visser  Christian M. Rogerson 《GeoJournal》2004,60(3):201-215

Under apartheid, tourism was essentially anti-developmental in focus and tourism research largely centred on the recreation of white South Africans. Since the 1994 democratic transition tourism has become recognised as an increasingly important sector for South Africa's economy and for achieving the government's goals for reconstruction and development. In this paper a review and critical analysis is presented of the changing directions and foci of tourism scholarship in South Africa. It is shown that South African scholars are beginning to respond to the challenges posed by tourism as a developmental focus.

文化与旅游互动机理探析--以腾冲县旅游发展为例   总被引：1，自引：5，他引：1  

包广静  李春燕  武友德 《云南地理环境研究》2004,16(2):44-47

文化是旅游业发展的灵魂所在，是激发旅游者旅游动机的主要因素之一，文化差异越大，能为旅游业所利用的文化资源也就越多；旅游业的发展又能为文化的发展创造条件，文化与旅游业的发展在多个层面上存在着互动关系。从影响旅游业的文化层面出发，分析了文化与旅游业的相互关系，认为文化与旅游能够实现互动发展，通过腾冲的实证研究，对文化与旅游的互动关系作了进一步说明。  相似文献   

国内旅游文化开发研究综述   总被引：6，自引：0，他引：6  

赵飞  彭华  姚静 《云南地理环境研究》2004,16(2):48-52

旅游文化是一种重要的旅游资源。是旅游地可持续发展的源泉。在旅游地开发过程中，文化事项如何转化为旅游产品，即旅游文化开发是一个极具实际应用价值的研究课题。目前，国内对于旅游文化开发的研究还没有能够形成一个完整的理论研究体系，并且缺少成熟的研究方法，具体到实践中可操作性还比较弱。在查阅了国内近20年中的众多相关研究文献的基础上，试图从应用理论、开发实践、方法探索3个方面对国内的旅游文化开发研究做一个系统的总结。  相似文献   

The Singapore River thematic zone: sustainable tourism in an urban context   总被引：5，自引：0，他引：5  

Victor R Savage  Shirlena Huang  T C Chang 《The Geographical journal》2004,170(3):212-225

This paper explores the concept of sustainable tourism and how it applies to urban destinations such as Singapore. As tourism is an important industry in Singapore, in terms of employment, business activity and an income generator, the Singapore Tourism Board is continuously looking at potential avenues to make Singapore a competitive destination. We examine the use of thematic zones in Singapore as a strategy to achieve its ambition of becoming a tourism capital of the world. By focusing on a case study of the Singapore River thematic zone (one of the 11 thematic zones identified by the Singapore Tourism Board), we assess the viability of thematic zones in ensuring sustainable urban tourism. The paper closes with some theoretical reflections and policy implications arising from our key findings.  相似文献   

亚、欧两大洲自然地理环境结构的整体性和差异性教学初探     

娄昭 《世界地理研究》2004,13(2):109-112

地理环境的结构，是指地理环境各组成要素之间和各组成部分之间相互关系性质的组合，它包括既有联系、又有区别的两个方面，即地理环境结构的整体性和差异性。笔者在亚、欧两洲自然地理数年的教学实践中，从自然环境结构的整体性和差异性特征入手，得出分析、综合、概括归纳和对比研究等方法是学习世界区域地理的主要方法。  相似文献
