草原旅游发展的实践及空间格局研究   总被引：6，自引：0，他引：6  

吕君  刘丽梅 《世界地理研究》2006,15(4):100-106

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。  相似文献   

发展中山会展旅游的思考   总被引：2，自引：0，他引：2  

周礼坤  钟国平  江宁进 《云南地理环境研究》2006,18(1):22-25

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   

A Decision Support System for the Evaluation of Eco-engineering Strategies for Slope Protection     

S. B. Mickovski  L. P. H. Van Beek 《Geotechnical and Geological Engineering》2006,24(3):483-498

A decision support system (DSS) has been developed to assist expert and non-expert users in the evaluation and selection of eco-engineering strategies for slope protection. This DSS combines a qualitative hazard assessment of erosion and mass movements with a detailed catalogue of eco-engineering strategies for slope protection of which the suitability is evaluated in relation to the data entered. The slope decision support system (SDSS) is a knowledge based DSS in which knowledge is stored in frames containing rules that can evaluate the available information for a project, stored as project specific information (PSI) in a data file. The advantages of such a system are that it accepts incomplete information and that the qualitative nature of the information does not instil the user with a sense of unjustified exactitude. By its multidisciplinary and progressive nature, the DSS will be of value during the initial stages of an eco-engineering project when data collection and the potential of different eco-engineering strategies are considered. The accent of the output of the DSS is on the application of eco-engineering strategies for slope protection as an environmentally-friendly solution aiding sustainable development. For its acceptance within the engineering community, the DSS needs to prove its predictive capacity. Therefore, its performance has been benchmarked against successful and unsuccessful cases of slope stabilisation using eco-engineering. The target audience and the areas of application of this DSS are reviewed and the strategies for further development in this area suggested.  相似文献

Groundwater study using remote sensing and geographic information systems (GIS) in the central highlands of Eritrea   总被引：3，自引：1，他引：3  

Semere Solomon  Friedrich Quiel 《Hydrogeology Journal》2006,14(6):1029-1041

Remote sensing, evaluation of digital elevation models (DEM), geographic information systems (GIS) and fieldwork techniques were combined to study the groundwater conditions in Eritrea. Remote sensing data were interpreted to produce lithological and lineament maps. DEM was used for lineament and geomorphologic mapping. Field studies permitted the study of structures and correlated them with lineament interpretations. Hydrogeological setting of springs and wells were investigated in the field, from well logs and pumping test data. All thematic layers were integrated and analysed in a GIS. Results show that groundwater occurrence is controlled by lithology, structures and landforms. Highest yields occur in basaltic rocks and are due to primary and secondary porosities. High yielding wells and springs are often related to large lineaments, lineament intersections and corresponding structural features. In metamorphic and igneous intrusive rocks with rugged landforms, groundwater occurs mainly in drainage channels with valley fill deposits. Zones of very good groundwater potential are characteristic for basaltic layers overlying lateritized crystalline rocks, flat topography with dense lineaments and structurally controlled drainage channels with valley fill deposits. The overall results demonstrate that the use of remote sensing and GIS provide potentially powerful tools to study groundwater resources and design a suitable exploration plan.The online version of the original article can be found at  相似文献

Organizational Dynamics of the U.S. Logistics Industry: An Economic Geography Perspective*     

Yuko Aoyama  Samuel Ratick  Guido Schwarz 《The Professional geographer》2006,58(3):327-340

Although the logistics industry provides critical services to all sectors of the economy, few studies exist in economic geography that examine and explain the organizational dynamics of this industry. This article highlights the significance of the logistics industry in contemporary industrialization and argues that an enriched understanding of the interaction between technology and space can be achieved by examining the evolution of an industry that plays a central role in the contemporary economy. We focus on dimensions that are identified as particularly important: organizational, geographic, and risk and security.  相似文献
