会展旅游是当今世界旅游业发展的一个重要方向，是一个蕴涵巨大价值的旅游项目，是都市旅游不可或缺的一部分。中山会展旅游不仅有着良好的区位条件，而且具有持续发展的良好经济环境。但中山会展旅游的宜传、促销力度不够，专业人才匮乏，市场运作不完善，旅游辅助作用有限，同时，面临周边城市的激烈竞争。对此，应把会展旅游作为培育中山旅游的重要动力来认识，加强对会展旅游的宣传推广，提高认识；培养专业人才，建立会展旅游组织；强化特色，准确定位；广泛协作联合，使广州的会展旅游走上可持续发展轨道。  相似文献   

The changing role of hydrogeology in semi-arid southern and eastern Africa     

N. S. Robins  J. Davies  J. L. Farr  R. C. Calow 《Hydrogeology Journal》2006,14(8):1483-1492

Much of southern and eastern Africa is semi-arid and heavily groundwater dependent. Borehole drilling commenced over a hundred years ago with magnetic and electrical resistivity surveys for borehole siting being introduced from 1936. Formalised training of hydrogeologists led in the 1970s to an almost standard approach to hydrogeological investigation and a period of stability followed, during which some major investigations were carried out. A period of decentralisation and fragmentation has since taken place in many parts of southern and eastern Africa, and groundwater monitoring and management are inadequate in many countries. All but six of the 14 SADC (Southern African Development Community) member states reportedly have an adequate monitoring network in place. However, groundwater demand is increasing and hydrogeologists need to promote the use of appropriate methodologies as an essential part of tackling the severe issues now facing the water sector in the region.  相似文献   

Impact of Flood Disasters on Taiwan in the Last Quarter Century     

Wei-Hsien Teng  Ming-Hsi Hsu  Chung-Hsing Wu  Albert S. Chen 《Natural Hazards》2006,37(1-2):191-207

The increasing natural disasters, especially floods during the last quarter century, are raising the economic losses in Taiwan. The most severe hazard in Taiwan is flooding induced by typhoons and storms in summer and autumn. By comparing the rivers around the world, the ones in Taiwan have the steepest slopes, the largest discharge per unit drainage area, and the shortest time of concentrations. Rapid urbanization without proper land uses managements usually worsen the flood problems. Consequently, flood hazards mitigation has become the most essential task for Taiwan to deal with. Although the government keeps improving flood defense structures, the flood damage grows continuously. In this article, possible flood mitigation strategies are identified for coping with complex environmental and social decisions with flood risk involved.  相似文献   

A new approach for the development and management of brackish karst springs     

Athanasios Maramathas 《Hydrogeology Journal》2006,14(7):1360-1366

A new approach to the method of artificial upraising of the water outlet point, for management and development of brackish karst springs, uses the MODKARST model. Brackish karst springs simulation can be used to estimate the necessary upraising of the spring elevation, so that sea-water intrusion is blocked. The consequent freshwater loss to the sea, due to this upraising, can also be estimated. The method has been applied to the periodically brackish karst Almiros spring at Heraklion of Crete, Greece. The spring simulation showed that the sea-water intrusion could be prevented through an artificial upraising of the water-outlet point, realized by the construction of a dam. The exact upraising has been estimated. Freshwater loss to the sea because of this upraising has also been estimated. The model could also be used as a tool for the management of the spring. For example, it was used to assess management options for the spring during the depletion period of the year 1994. The best scenario for the development of the spring during this period has been estimated.  相似文献

HUMBOLDT'S MEXICAN TEXTS AND LANDSCAPES*     

Andrew Sluyter 《Geographical review》2006,96(3):361-381

ABSTRACT. While in New Spain from 1803 to 1804, Alexander von Humboldt interacted with some of its landscapes and the texts that represented them. Analysis of those interactions regarding the Basin of Mexico and the Gulf lowlands demonstrates what purely text‐based studies of the production of places cannot: The contrasting landscape elements and patterns that had emerged over millennia during precolonial times in those two places, their relative degrees of depopulation during the colonial era, and the relative degrees of rigor Humboldt applied to interacting with the resulting landscapes and the texts that represented them greatly affected his representations of those places in his 1811 Essai politique sur le royaume de la Nouvelle‐Espagne. His representations of the precolonial Basin of Mexico as productively developed and of the precolonial Gulf lowlands as pristine have influenced the transformations of those places in the two centuries after New Spain became the Mexican republic through its wars of independence (1810–1821).  相似文献   

Subaltern strategies and development practice: urban water privatization in Ghana   总被引：1，自引：0，他引：1  

IAN YEBOAH 《The Geographical journal》2006,172(1):50-65

This paper is concerned with subaltern actions providing alternatives to development practice. I use Ghana's attempt at urban water privatization to illustrate that Ghana's development practice is characterized by a dependence on foreign sources of capital and expertise that illustrates a psyche and mindset of Eurocentrism associated with the elite and decisionmakers of the country. The rationale for water privatization, the how of privatization, and the anti-development opposition to privatization not only demonstrate this dependency but also the extent to which decisionmakers are willing to sacrifice sovereignty and culturally sensitive ways of doing things, to global capital, in exchange for development funds. In the state's zeal for Western or Occidental development, subalterns in Ghana have devised hybridities that are post-traditional and Oriental in nature to solve their water problems. These development solutions are couched within structures provided to human agency and suggest that development practice should therefore listen to subalterns in terms of how they imagine and solve their problems. The concern with subaltern voices shows the relationship between postcolonial studies and development practice.  相似文献   

Managing sustainable farmed landscape through 'alternative' food networks: a case study from Italy   总被引：1，自引：0，他引：1  

LEWIS HOLLOWAY  ROSIE COX†  LAURA VENN‡  MOYA KNEAFSEY‡  ELIZABETH DOWLER§  HELENA TUOMAINEN§ 《The Geographical journal》2006,172(3):219-229

This paper focuses on a case study of an 'alternative' food network based in the Abruzzo National Park, Italy, to explore how ideas of sustainable farmland management can be expressed through broader understandings of developing networks of care concerned with local economies and societies, high-quality specialist food products, particular 'traditional' farming practices and livestock breeds, as well as the ecology of a farmed landscape. The scheme allows customers, internationally as well as in Italy, to 'adopt' a milking sheep on a large mountain farm. In return, adopters are sent food products from the farm. The adoption scheme is inter-twined with an agri-tourism project which provides accommodation, runs a restaurant and engages in educational activities. The scheme is the result of the individual initiative of its founder, and is associated with a strongly expressed ethical position concerning the value of sustaining valued local rural landscapes and lifestyles, and the importance of 'reconnecting' urban dwellers with rural areas, farming and 'quality' food production. Yet the localness of the scheme is sustained through wider national and international networks: volunteer and paid workers are drawn from several European countries, funding has been acquired from the EU LEADER programme, and internet and transport technologies are essential in connecting with and supplying an international customer base. The broader economy of care instanced in this case study draws attention to a need to develop strategies for sustainable farmland management constructed around wider programmes of social, economic and cultural, as well as environmental, concern.  相似文献   

Spatial practices and imaginaries: Experiences of colonial officers and development professionals     

Uma Kothari 《Singapore journal of tropical geography》2006,27(3):235-253

This paper explores the spatiality of colonial and postcolonial power and discourse as produced, performed and imagined by former British colonial service officers and contemporary UK international development professionals. It focuses on two key aspects of spatial practices. The first addresses the spaces inhabited by these colonial officers and development professionals overseas and how their locatedness, embedded or enclavic, shapes relationships to others. The second explores this distinctive social and spatial distancing through their relationship to, and imagined geographies of, home and away and how these are embodied in their institutional and cultural capital. The paper examines the regularities and consistencies that stand out from numerous individual practices through which both former colonial officers and development professionals negotiate the situations in which they live and work. It also specifies how authoritative management, privilege and distance informs their spatial practices despite changing global contexts and a more diverse composition of those who articulate contemporary relationships between 'first' and 'third' worlds. Finally, the paper suggests that the cultures which travelled over colonial space through being performed by colonial officers have been reworked throughout the postcolonial period, belying epochal historical periodizations that conjure up a clear disjuncture between colonial and development eras.  相似文献
