区域经济空间集中化的产业成因分析——兼析海南省经济空间集中化问题   总被引：1，自引：0，他引：1  

郑锋 《热带地理》2002,22(4):304-308,314

经济空间集中化起因于产业经济活动在一定空间内聚集并形成大规模的专业化生产，它以区域城市为增长中心，与区域产业结构转变有着密切的关系。经济空间集中化过程大致可以划分为三个与区域产业结构转变有关的经济增长阶段：初级阶段——均衡低速增长；中级阶段——集中快速增长；高级阶段——稳定增长。  相似文献

中国西部山区是我国的水源地及生态屏障，它们的合理开发与保护是西部大开发的基本内容。研究归纳出山地发展的“巴音布鲁克模式”：（1）天鹅及其生境的绝对保护（核心）；（2）建立可持续牧业（主体）；（3）规范和发展旅游业（突破口）；（4）西蒙古土尔扈特传统文化的保护（文化多样性）。中国西部山区的发展模式都可以概括为一个核心（自然保护）三个圈层（与当地主要土地资源相适应的主导产业，与当地特有资源相联系的新兴产业，当地民族文化保护）。这种模式能够充分体现生态优先的思想，同时考虑到促进地区新老经济及文化的发展与保护，符合西部大开发的方针。  相似文献

资源环境与社会经济协调发展探析   总被引：15，自引：2，他引：15  

李胜芬  刘斐 《地域研究与开发》2002,21(1):78-80

文章首先回顾了资源环境与社会经济发展的理论，提出资源环境与社会经济协调发展内涵：一方面，要在资源环境承载力范围内发展社会经济，追求社会经济发展的最大化，另一方面，环境承载力是动态的，要依靠社会经济发展不断提高，这两个方面是相互作用、相互制约的。在此基础上，详细论述了资源环境与社会经济协调发展的内容,并从社会经济发展、资源环境管理等角度探讨了资源环境与社会经济协调发展的政策调控，通过建立节约型国民经济体系、深化资源环境管理，实现区域一体化，以保证资源环境与社会经济协调发展的实现。  相似文献

1 Introduction Soil is not only the major natural resource on which human being depends for the production of food, feed, fiber, renewable energy and raw materials, but also plays a key role in maintaining the complex terrestrial ecosystems and climate systems of this planet. Recent rapid increase in the human population is placing a great strain on the worlds soil resources.

History and necessity: the evolution of soil conservation technology in a Jamaican farming system     

Rebecca J. Kent 《The Geographical journal》2002,168(1):48-56

The soil conservation campaigns that have been a prominent feature of Jamaican agricultural policy since the 1950s are frequently presented as having failed to ameliorate the problem of soil erosion in hillside agriculture. A case study of a small farming community in the Blue Mountains explores the development of the soil conservation practices currently employed by farmers. The use of trash barriers in carrot farming is described and the origins of this technology and its subsequent adaptation are considered. The study concludes that extension interventions and government policy have influenced the development of current soil conservation practices; practices which have their roots in indigenous techniques. Other factors such as the adaptation of trash barriers to suit local conditions and their importance in soil fertility management also play a role in their widespread use in the study area. The study demonstrates that to understand the process of technical change in farming communities, it is necessary to consider a range of factors, external and internal, technical and social, that have over time influenced farmers' decision making.  相似文献   

Luxury Tourism and Regional Economic Development in Mexico   总被引：1，自引：0，他引：1  

Ludger Brenner  Adrin Guillermo Aguilar 《The Professional geographer》2002,54(4):500-520

This article argues that little attention has been paid to the territorial and socioeconomic impact of consumer–service globalization on Third World countries. It specifically examines the economic role of tourism in Mexico and its limited effect on the country's regional development. Despite governmental support in order to enhance economic growth, currency receipts, and employment, tourism contributes less than 5 percent to the gross domestic product, and the majority of tourism–related jobs are precarious and low–skilled. The promotion of luxury resorts in coastal areas has led to highly concentrated and fast–growing enclaves of mainly foreign investment. However, this strategy has failed to stimulate productive links between tourist centers and their hinterlands and has led to large–scale urbanization characterized by a considerable lack of basic services for the resident population.  相似文献
