The path of urbanization in the People's Republic of China is largely shaped by the nation's industrial development strategies. In the first three decades of socialist construction, and especially after the Sino-Soviet rift at the end of the 1950s, the adoption of strategies of self-reliance had led to urban biased patterns of development. The introduction of economic reforms and the open door policy in 1978 paved the way for and facilitated national economic development. Two issues, which feature significantly in the processes of development in China, are assessed. The first is the relationship between economic development and the protection of arable land. The second is the quest for a coordinated hyper-development in both urban and rural areas. This paper concludes by proposing a sustainable metropolitan development strategy that suits the case of China. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

煤炭是我国的主要能源,也是我国长期以来发展的最重要驱动力,并且在未来很长一段时间内将继续作为我国社会与经济发展的主要能源。但我国长期的煤炭开采活动已经对生态环境造成严重破坏,亟待进行全面生态恢复。目前,我国煤矿生态恢复大多局限于一处或几处矿区这类小尺度范围,缺乏国土空间层面的生态修复规划,相应的生态恢复策略也仍待明确。煤矿生态恢复是一项全国性系统生态工程,应以“借自然之力恢复自然”为理念,以当地生态敏感性问题为依据,以停止破坏自然生态系统并且继续提供生态系统服务为宗旨,以改善矿区人居环境质量为出发点。全国煤矿生态恢复策略的制定基于以下4个方面:第一,以我国植被区划为基础,因地制宜地选择潜在植被类型;第二,计算归一化综合生态敏感性(NIES)用以表征煤矿生态恢复紧迫性,再借助空间自相关性分析判断不同NIES煤矿的聚集关系与模式;第三,对煤矿和当地人口分布情况进行缓冲区分析,得到煤矿生态恢复的获益人口;第四,将煤矿的NIES和煤矿恢复获益人数进行聚类分析,判断煤矿生态恢复的优先区域。综合上述结果,根据我国煤矿的空间分布情况分区域制定相应的生态恢复策略。   相似文献

Carbon verification, which can guarantee the reliability and credibility of greenhouse gas (GHG) emission data, is the most important part of the daily operations of the carbon emission right trading system. Many international institutions, countries and regions have conducted research on and have practiced carbon verification policies and systems. Through comparative analysis of the international carbon verification policies and systems, they can provide experience for Chinese unified national carbon market to start supporting carbon verification. The paper study concludes that (1) carbon verification systems developed by international institutions focus on the scientific level of verification methods; (2) carbon verification policies and systems issued by important countries and regions draw on International Standardization Organization (ISO)14064 standards based on their national conditions and focus on the scientific level and reasonableness of verification methods; (3) major international experience includes complete verification policies and systems, strict standard verification procedures, diversified verification forms and a focus on key emission sources. Based on the differences in China’s carbon emissions characteristics caused by unbalanced regional economic development and the conditions of carbon verification in seven pilot carbon trading areas, this thesis proposes the following suggestions: pushing forward the establishment of carbon verification policies and systems by accelerating legislation on climate changes; facilitating carbon verification in a coordinated manner; regulating key GHG emission sources; establishing and improving supervision on carbon verification; and intensifying international exchanges and cooperation.

Macro government policies are often considered outside the context of their spatial impact. Following recent discussions of the problem, this paper is concerned with a critical review of Canadian Manpower policy in the context of national efficiency, regional equity and their interaction. Thus Manpower policy is analysed with respect to its implications concerning regional development as well as implicit regional policy. It is contended that many of the problems of Manpower policy in the spatial context can be traced back to the implicit theoretical background of Manpower policy; Human Capital theory. A radical critique of Human Capital theory is presented and a brief discussion of the ‘functional’ relationship between regional inequality and national macro-planning is also noted. In general the paper concludes that Manpower and regional policies in Canada tend to be contradictory although more research is needed to analyse the spatial impact of macro-policy which may overwhelm spatial policy and significantly influence the future of the spatial economy.  相似文献

This paper analyzes the current state of water environment protections in China and explores the need for technology imports in this field. Few studies have discussed the import of water environment technologies in China. In particular, there is a lack of research on the competition policies of technology-importing countries. Based on the retrieval and analysis of technology patents in the water environment field, as well as the research on relevant competition policies, this paper indicates that China shall import and learn about related technologies from developed countries, such as the US and the EU. In addition, China ought to pay more attention to relevant EU competition policies. The relationship between water environment protections and EU market competition policies could serve as a reference for green exemption practices in Chinese anti-trust law. Lastly, this paper analyzes China’s relevant competition policy. It is also helpful for potential foreign investors to understand the transparent institutional framework.  相似文献

There is no standard model of transformation for post- socialist countries and each country encounters specific problems rooted in the geographical characteristics of the areas concerned. The human resources are of the greatest importance because it really matters how people (especially the decision-makers) perceive system change and continually reformulate their expectations and strategies; so investigations into the views of people caught up in the transformation can provide a deeper understanding of the background to structural change. Working the national, regional level and local levels in Romania, experts were asked to consider the advantages and disadvantages arising out of the transformation, the most important problems and constraints for future rural development and the policies needed. The paper examines the responses on demographic and social issues. It emerges the most detailed responses were supplied by local-level representatives while respondents at the regional level steered a middle course between the need to address local problems and the prime importance of stimulating the Romanian economy so as to generate resources for welfare programmes (with the latter issue the overriding concern of interviewees at national level). There was general agreement on the importance of foreign investment and European integration for economic development, with local actors taking only small steps in line with the existing opportunities. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

China’s petrochemical industries are playing an important role in China’s economic development. However, the industries consume large amounts of energy and have become primary sources of carbon emission. In this paper, the change in carbon emissions from China’s petrochemical industries between 2000 and 2010 was quantitatively analyzed with the Log-Mean Divisia Index method, which was decomposed into economic output effect, industrial structural effect and technical effect. The results show that economic output effect is the most important factor driving carbon emission growth in China’s petrochemical industries; industrial structural effect has certain decrement effect on carbon emissions; adjustment of industrial structure by developing low-carbon emission industrial sectors may be a better choice for reducing carbon emissions; and the impact of technical effect varies considerably without showing any clear decrement effect trend over the period of year 2000–2010. The biggest challenge is how to make use of these factors to balance the relationship between economic development and carbon emissions. This study will promote a more comprehensive understanding of the inter-relationships of economic development, industrial structural shift, technical effect and carbon emissions in China’s petrochemical industries and is helpful for exploration of relevant strategies to reduce carbon emissions.  相似文献

The sustainable management of China’s rivers is very important to the well-being of both the environment and its people. Yet the country’s rivers are now facing imminent threats from river overexploitation. The deteriorating condition serves as a stark reminder that relevant policies must be revised to ensure their wiser stewardship. In this short critical review, we first briefly stated river development history and various impacts arising from river overexploitation. We then elaborated the issues in river management, which connived numerous behaviors neglecting river degradation happened at all institutional levels. Based on the weakness, we proposed some policy recommendations to sustain China’s rivers and balance river development and conservation. The article concludes by proposing the development of a national river protection law to reinforce integrated river management, improve the implementation of environment impact assessments, and fulfill long-term goals for river conservation and sustainable development.  相似文献

Kenya has been promoting equitable urban and regional development since the 1970s despite the lack of a clearly formulated national urban policy or an urban and regional development policy. A key element of the country’s equitable urban and regional development effort is the promotion of secondary cities that would relieve population pressure in the countryside, help to better integrate the country’s rural and urban economies, help to reduce congestion and improve the quality of life in the metropolitan cities of Nairobi and Mombasa, and help increase the modernization spin-off which urban centers provide to the surrounding rural areas. Using recent census and economic survey data, this paper examines the current state of Kenya’s secondary cities in the context of its urban and regional development strategies. The paper finds that: (1) the country’s urban and regional development strategies have failed to work as planned largely because of insufficient devolution of power and fiscal responsibility to municipal and other local government units, (2) the country’s secondary cities are faced with immense challenges that undermine their ability to live up to expectations, (3) some of these cities have significantly grown economically over the last four decades despite immense challenges, and (4) Nairobi’s dominance of Kenya’s economy continues because of policies that unwittingly concentrate investments there. The paper concludes with strategies that could enhance the country’s urban and regional development programs and, in the process, aid the development of its secondary cities.  相似文献

区域发展地学基础综合研究的意义、进展与任务   总被引:11,自引:0,他引:11  
区域发展问题是一个重大的地学问题。由于背景和驱动力的变化,我国的区域发展正面临着一系列复杂问题;解决这些问题很大程度上依赖于对我国区域发展"地学基础"的深刻认识和研究。这种研究不但具有重大实际意义,也是发展地理科学和深化地球表层系统研究的重要途径。论述了区域发展地学基础综合研究的意义,回顾和评价了国内外在此领域内的研究进展,提出研究的目标和任务。国内外近年来的研究表明,人文与自然要素的交叉和综合研究正在成为区域发展研究的前沿领域。我国在影响区域发展的单要素和多要素研究上取得了丰富的积累,而且地球表层系统中"人地关系"综合研究思想也已经兴起了10多年,但真正的交叉和综合研究还很少。进行我国区域发展地学基础综合研究的目标是阐明我国自然和人文要素的区域分异特征及其与区域发展分异之间的耦合关系,揭示地学因素在各时期影响我国区域发展的综合作用机制。  相似文献
