环境与发展中的南北关系   总被引：1，自引：0，他引：1  

田亚平  徐慧 《世界地理研究》2001,10(1):84-90

在环境与发展的问题上，发达国家与发展中国家之间存在着一种既利益相关又矛盾对立，既有合作又有斗争的相互关系，尤其是围绕温室气体排放和环境贸易问题的合作谈判始终伴随着激烈的南北冲突，作为发展中国家的环境大国，面对环境与发展的国际合作趋势和来自发达国家的挑战，应该采取积极对策，一方面积极开展环境外交，围绕斗争，争取利益，维护主权；另一方面加强环境对策及其理论研究，完善自身环境管理机制，为促进环境与发展的南北合作创造条件。  相似文献

海南省三亚市的生态环境建设     

陈朝辉 《热带地理》2001,21(3):202-206,222

三亚市位于海南岛最南部，具有得天独厚的生态环境优势。近20年来，生态环境建设虽取得初步成效，但问题也较突出，如林业尚存隐患，耕地锐减，水域受蚕食和局部环境恶化，城市绿化美化不足等。生态环境建设面临的任务主要是：合理布局城镇，建设具有经济－生态良性循环的城乡体系；完善林业生态体系建设，建成强有力的陆地生态支柱；保护好水体环境，搞好碧水工程建设；保护耕地、保证农业持续发展；整治环境，提高环境质量。为此必须采取相应措施。  相似文献   

'They don't like girls hanging around there': conflicts over recreational space in rural Northamptonshire     

Faith Tucker  & Hugh Matthews 《Area》2001,33(2):161-168

This paper provides new insights into girls' use of recreational spaces within rural areas. We draw upon data from in-depth discussion work with 10–14 year old girls undertaken in rural Northamptonshire to show how conflict between adults and children, rival groups of children, and boys and girls influences the social ownership of recreational spaces. In contrast to the rural childhood myth, we disclose geographies of anxiety, tension anddisharmony.  相似文献   

Dilemmas of development in Oceania: the political economy of the Tongan agro-export sector     

Donovan Storey  & Warwick E. Murray 《The Geographical journal》2001,167(4):291-304

This article critically engages with the recent diffusion of the orthodox development model in Oceania and highlights some evolving dilemmas. In particular, it explores the social, economic and ecological tensions arising from economic reforms that are exacerbating the fragility of already vulnerable nation-states and communities. In order to illustrate its arguments, a case study of the impacts of agro-export growth in Tonga is presented. Attention is drawn to the socially inequitable and ecologically unsustainable outcomes of rapid growth in this sector. In analyzing the political economy of the squash pumpkin sector, the authors point to the important role that culture plays in mediating and conditioning development outcomes. Reflecting on the Tongan case, it is argued that to better understand the implications of orthodox developmental reform in the region, research must seek to more explicitly incorporate distributional and ethical analysis.  相似文献   

Globalisation, Regionalisation and Local Voices: The Asian Development Bank and Rescaled Politics of Environment in the Mekong Region   总被引：1，自引：0，他引：1  

Philip Hirsch 《Singapore journal of tropical geography》2001,22(3):237-251

Globalisation is manifested in the Mekong Region both through processes and discourses that reflect the ideology of a borderless world allowing easy passage of capital and commodities, and through resistance to such processes in an increasingly transnationalised civil society movement. However, more immediately significant supranational integrative agendas take the form of regionalisation, a process that has received less attention but which raises analogous concerns of re-scaled governance. The Asian Development Bank (ADB) has been a catalysing force for regionalisation amidst a host of regional processes and initiatives; as such it has found itself the object of critique as an institution and through the specific projects it has supported that have impacted on local communities and ecosystems. Meanwhile, local and NGO voices associated with the emergence of a vibrant civil society in Thailand and nascent civil society responses in neighbouring countries have challenged claims on resources made in the name of national development and regional integration.
This paper considers some key issues of re-scaling resource and environmental politics in the Mekong Region, and the extent to which challenges have been recast from national to regional development agendas. Politics of environment are shown to exist as a general rather than exceptional response to the region's development direction, and it is suggested that equitable and sustainable development increasingly needs to address simultaneously the re-scaling and reconfigurations of power in both environmental politics and the "infrapolitics" of environment. The paper is illustrated with case studies of dams in Laos and Thailand.  相似文献   

The impacts of urbanization on soil erosion in the Loess Plateau region   总被引：1，自引：0，他引：1  

SUN Hu  GAN Zhi-mao  YAN Jun-ping 《地理学报》2001,11(3):282-290

The accelerated urbanization has resulted in new soil erosion in the Loess Plateau region since the 1980s. A concept of urban erosion and its impacts on environment are discussed. The experimental studies and field investigations show that those loose silt and earth piles formed by urban construction can be eroded seriously: Under stormy rain, the amount of sediment from steep man-dumped slope is 10.8-12.2 times that of from uncovered slope land; the result of experiments with the wind tunnel also shows that the damage to the surface structure of dry loess can cause serious soil erosion by wind in some cities of the region. Even if in the urban built-up area, there are many loose sandy soil, mud and silt, which are washed into rivers by city’s ground flow in the rainy season. So, anthropogenically induced soil erosion has made soil erosion more serious around the urban areas. And the urban eroded environment has several characteristics such as fragility, complexity, seasonality and quick variability. Urban areas witness a quick economic growth and have more construction projects than rural areas, which brings more intensive changes of environments during a short period of time or adds some new elements to the erosion system. Therefore erosion has experienced more intensive impact by human activities. So, the possible impact of urbanization on erosion environment must be taken into consideration when designing or planning to exploit natural resources or to develop urban areas in the Loess Plateau.  相似文献

许英勤  胡玉昆  马彦华 《干旱区地理》2001,24(4):342-346

随着塔里木河流域进入大规模开发时期，区域开发活动对该流域生态环境的演变产生了重大的影响，虽然绿洲内部产出大幅度增加，但整体生态环境趋向恶化，制约了区域社会经济的可持续发展。以塔里木河中下游尉犁县为例，从分析区域开发活动入手，总结了区域开发对区域生态环境影响的有利与不利方面，进而，讨论了区域生态环境恢复与重建的对策。  相似文献
