成都市城市效应对大气环境的影响

本文利用1979—1981年气象资料用统计方法分析了城市热岛效应对主要气象要素时空分布特征的影响(例如:温度、无霜期、风速、日照、云量、降水量、雷暴、雨日、雾日和土壤温度),结果表明:城市效应对市区大气环境的影响是明显的。     

体育旅游产品消费的文化背景

人们的消费具有社会性,因而具有很强的时代性。在国内外兴起并迅速发展的体育旅游产品是时代的产物,它是休闲时代人们消费的主体产品,是体验经济时代旅游产品的升级换代产品。人们通过消费体育旅游产品,不但能休闲、娱乐、健身、交际,还能发展自己、完善自己、实现自我价值,从而迎合了知识经济时代人们消费的价值观。我国有极其丰富优越的体育旅游资源,关注并开发体育旅游市场是我国旅游业可持续发展的重要战略。     

徽州村落旅游开发初探

村落旅游是我国近年来出现的一种新兴的特种旅游方式,表现出强劲的市场需求态势和良好的发展前景。文章以徽州为对象,对村落旅游的发展条件、市场需求、活动特点进行分析,并对村落旅游的开发、活动组织等方面进行了探讨,旨在为更好地利用区域这一普遍存在的旅游资源,完善区域旅游产品结构,实现区域旅游发展的整体推进提供一些有益的参考。     

城市旅游环境承载力及其旅游资源空间管理

UTECC主要充当控制旅游需求的功能。UTECC的降低最明显的后果就是损害了城市的生态环境质量,紧接着会导致旅游需求的降低。为了实现城市旅游可持续发展,城市的旅游需求不能超过旅游环境承载力。通常对城市旅游资源过度需求的空间管理方法主要有5种。本文在AlanCollins(1999年)研究的基础上提出了城市旅游环境承载力的概念,并借助城市旅游资源过度需求管理方面的理论对如何使用及防止滥用城市旅游环境承载力作了初步研究。     

山东省生物旅游资源及其开发保护

本文对生物旅游资源的概念和山东省生物旅游资源的现状、开发和保护作了初步探讨。生物旅游资源是旅游资源体系的重要组成部分,主要包括植物旅游资源和动物旅游资源两大类。山东省地理位置优越,生态环境多样,因而具有极为丰富的生物旅游资源.突出表现在种类丰富,珍稀种类众多,时空分布格局较好,鸟类、温带花果为其优势资源,具有较高的观赏、游览和科学考察价值。丰富的生物旅游资源在山东的旅游业中占有独特的位置,应该科学、合理地加以开发,开展生态旅游、观鸟旅游、观果、赏花旅游及科学考察旅游,在开发利用的同时,加强保护。     

The impact of global warming on winter tourism and skiing: a regionalised model for Austrian snow conditions

Possible climate change will modify snow-cover depth and change the characteristics of winter tourism and skiing districts. Our model describes seasonal snow-cover depth related to altitude in six Alpine climate regions as the best fit of all snow stations. Data cover 30 winter seasons (November to April values) from 1965 to 1995. We modified the data according to a scenario of temperature and precipitation change (2 °C warming, no precipitation change) and achieve a new simulated snow-cover depth. The indicators MARP (mean altitude of resident population) and MASPSL (mean altitude of starting point of ski lifts) serve as references for “critical altitudes” of Austrian districts. A warming implies a reduction of snow in all districts, but the loss is overproportional in lower altitudes. The direction of economic impacts is clear – income losses and adaptation costs – but magnitude and time frames remain uncertain. Received: 24 February 1999 · Accepted: 15 May 1999     

Sustainable Tourism and the Touristic Ecological Footprint

There is growing interest in ecological footprint analysis in aiding our understanding of societal demands upon the biosphere. Increasingly, attention is being focused on potential new applications of the technique. Tourism is one of the world's largest industries and can play a major part in encouraging more consumerist lifestyles. It is now widely accepted that tourism development may have profound impacts on local environments, and that, consequently, the sustainable development of tourism at destination areas is an important issue. However, sustainable tourism studies rarely look beyond the destination area, and there has been no substantive recognition of the wider ecological footprint of tourism activities. This paper attempts to connect, conceptually, the realms of sustainable tourism and ecological footprint thinking. In so doing, various conceptualisations of the 'touristic ecological footprint' (TEF) are suggested, along with some potential applications. It is argued that primary research should focus on calculating the touristic ecological footprint associated with individual tourism products, throughout the product's life-cycle. As well as bringing another dimension to our understanding of tourism's actual ecological demand, it is also argued that the concept of the touristic ecological footprint may be used to clarify theoretical aspects of the sustainable tourism debate, helping to rejuvenate this debate in the process.

Sustainable Development in Small Island Developing States

This paper explores the status of sustainable development in small island developing states (SIDS), through the presentation of a case study on the Maldives, which is a typical small island developing state in the Central Indian Ocean. At the outset, a brief history of sustainable development as related to SIDS on the international agenda is outlined, starting from Rio to Barbados to Johannesburg. SIDS are expected to face many challenges and constraints in pursuing sustainable development due to their ecological fragility and economic vulnerability. It is the position of this paper that issues related to environmental vulnerability are of the greatest concern. A healthy environment is the basis of all life-support systems, including that of human well-being and socio-economic development. Priority environmental problems are: climate change and sea-level rise, threats to biodiversity, threats to freshwater resources, degradation of coastal environments, pollution, energy and tourism. Among these, climate change and its associated impacts are expected to pose the greatest threat to the environment and therefore to sustainable development. For small islands dependent on fragile marine ecosystems, in particular on coral reefs, for their livelihoods and living space, adverse effects of climate change such as increased frequency of extreme weather events and sea-level rise will exacerbate the challenges they already face. It is concluded that the paper path from Rio to Barbados to Johannesburg has made significant progress. However, much remains to be done at the practical level, particularly by the developed countries in terms of new and additional efforts at financial and technical assistance, to make sustainable development a reality for SIDS.
