楼观台森林公园深层生态旅游开发的模式探讨

提出了深层生态旅游开发的概念,构建了一个“两翼对接”模式。在广泛野外调查的基础上,依据上述理念和开发模型,针对楼观台国家森林公园的景观资源特征,对其深层生态旅游开发进行了系统设计。具体而言,重点突出了自然山水、生物景观和道教文化三方面设计,揭示了三大类60个景物的生态文化主题,设计了相应的开发展示模式和游客生态体验方式。其目的在于,提高森林公园生态文化的展示水平和加深旅游者的生态体验。     

基于芬兰经验的我国森林资源型城市的发展研究--以伊春市为例

资源型城市的可持续发展问题一直是学术界的研究热点,但对于森林资源型城市的研究却不多见。本文概括介绍了芬兰的资源和经济发展情况,系统分析了芬兰这样一个以森林起家的经济发达国家的成功经验;并以伊春为例提出了森林资源型城市经济转型和可持续发展可资借鉴的对策和建议。     

20世纪90年代以来中外区域规划研究的对比分析

区域规划是国家政府进行区域管理的重要手段和方式之一。为了落实科学发展观和对区域发展有效宏观调控,区域规划成为国家“十一五”规划的重要内容。本文对比分析了1990年代以来国外区域规划研究的主要进展、以及我国区域规划研究的特点与不足,以期为推动我国当前新一轮区域规划的理论研究和实践创新提供有益启示。     

草原旅游发展的实践及空间格局研究

草原以其辽阔、坦荡的景观以及风土人情构成一类旅游目的地,世界上拥有大片草原的国家都非常重视草原旅游业的发展。我国草原旅游发展也较快,形成了不同空间类型、不同植被景观类型和不同人文与自然结合类型的旅游发展格局,其中又以内蒙古最为突出。但是,由于草原生态系统的脆弱性,决定了草原旅游发展存在脆弱性,因此,在开发中需要更加严格的科学规划和管理。     

发展中山会展旅游的思考

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。     

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

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.     

Impact of Flood Disasters on Taiwan in the Last Quarter Century

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.     

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

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.     

R＆D投入的区位模式与区域经济发展

基于对中国R＆D投入的区位模式的实证检验，从投入一产出绩效的角度认为集中投入的区位模式具有较强的适宜性。利用聚类分析技术，按照R＆D的投入强度和及其对经济的带动效应、科技化效应、产业化效应将中国各省区划分为6类地区，具有代表性的是科技化模式和产业化模式。其中前者适合于技术存置较高的少数地区，而后者具有较强的借鉴意义。
