行政边界区域土地利用与空间发展模式研究——以长株潭结合部为例

以长株潭结合部暮云镇为例,主要采用2004与2010年土地利用数据,从动态变化与多维综合视角,对行政边界区域土地利用与空间发展的特征、机制及问题进行系统分析,在此基础上归纳理论模式。研究表明:①暮云镇土地利用结构由农村型向城镇型快速转变,城镇用地比重年均约增加2个百分点,其中居住、教育科研、交通和工业等用地增加显著;②受主体功能定位、过境通道建设、周边城市辐射差异和规划管理制度变迁等因素影响,暮云镇空间格局与扩张模式快速演变,芙蓉大道沿线新增城镇用地占全镇82.78%,北、中、南区域开发强度分别上升20.95%、7.96%和1.58%,城镇用地平均图斑面积增长2.04倍。③研究区土地利用与空间发展存在诸多阶段性和结构性问题,应加强综合路网建设、公共设施用地供给、建设用地优化布局与集约利用以及生态环境保护。     

旅游减贫与旅游再贫困:旅游发展中不同土地利用方式对贫困人口的影响

旅游发展能否真正减贫以及如何实现减贫应是当前旅游减贫大背景下备受讨论的焦点,并受到了国内外学术界积极关注。然纵观现有研究,对旅游减贫效果的实证探讨及细致剖析尚十分缺乏。本文选取旅游发展中对土地资源的利用作为研究视角,探讨这一过程对贫困人口生存状态的影响。研究以三亚亚龙湾度假区发展对周边两个村庄的土地使用（征用、租用）为例,采用多维贫困概念,探讨旅游发展给两村村民在收入、居住条件、就业及生产方式以及话语权等带来的影响。研究提出了旅游再贫困的概念,意在说明旅游发展在使贫困人口短暂富裕后再次陷入贫困状态的发展现象,是旅游发展之于贫困人口负面影响的一种表征。     

江苏省流动人口分布的格局演变及其驱动因素——基于城乡建设用地的探讨

基于乡镇单元人口普查数据以及相应年份的城乡建设用地数据,运用空间分析和统计分析方法,尝试分析城镇-农村尺度江苏省流动人口分布格局的时空演变特征,并揭示驱动人口流动的动力机制。结果表明：①规模分布特征是具有较长大值右尾部的正偏分布,总体的集聚趋势增强,城镇和乡村集聚流动人口差距变大;②空间呈现高值集聚特征,热点区主要集中在长江以南的城镇,沿江地区流动人口高密度区域逐渐连绵化;③增长变化呈现长江以北地区城镇的流入人口增加、农村的输出人口减少,以及长江以南地区城镇的流入人口快速增加、农村的流入人口普遍增加的特征;④经济发展水平差异、乡镇企业繁荣、交通可达和政策导向是影响江苏省流动人口集聚的四大动力。     

Opportunities and constraints for intensive agriculture in the Hawaiian archipelago prior to European contact

Intensive agricultural systems interact strongly and reciprocally with features of the lands they occupy, and with features of the societies that they support. We modeled the distribution of two forms of pre-European contact intensive agriculture – irrigated pondfields and rain-fed dryland systems – across the Hawaiian archipelago using a GIS approach based on climate, hydrology, topography, substrate age, and soil fertility. Model results closely match the archaeological evidence in defined locations. On a broader scale, we calculate that the youngest island, Hawai'i, could have supported 572 km² of intensive agriculture, 97% as rain-fed dryland field systems, while Kaua'i, the oldest island, could have supported 58 km², all as irrigated wetland systems. Irrigated systems have higher, more reliable yields and lower labor requirements than rain-fed dryland systems, so the total potential yield from Kaua'i (49k metric tons) was almost half that of Hawai'i (97k metric tons), although Kaua'i systems required only 0.05 of the agricultural labor (8400 workers, versus 165,000 on Hawai'i) to produce the crops. We conclude that environmental constraints to intensive agriculture across the archipelago created asymmetric production efficiencies, and therefore varying potentials for agricultural surplus. The implications both for the emergence of complex sociopolitical formations and for anthropogenic transformation of Hawaiian ecosystems are substantial.     

论“朝鲜中华主义”的实与虚

朝鲜后期,北伐论激起朝鲜士大夫小中华意识高度发展,因此有学者将其称为"朝鲜中华主义"。然而从事实来看,朝鲜士大夫虽然有很强的文化自尊意识,但是这种自尊意识是建立在春秋大一统之上的,小中华意识的发展反而使一元的天下观进一步强化,将中华秩序理想化。所以,朝鲜后期小中华意识的发展并不表示朝鲜士大夫以朝鲜为中华之正统或中国之正统,反而继续承认朝鲜为小中华,而在事实上更不证明朝鲜为当时东亚的文化中心国家,所以我们在使用"朝鲜中华主义"概念时尚需仔细斟酌。     

一切能力都是为人民执政——学习十七届四中全会《决定》

所谓党的执政能力,其本质就是为人民服务的本领。一切能力,都是为人民执政;一切能力,都要为人民执政。归根到底,党的执政能力要从人民群众的历史创造中来,要在与群众密切联系的实践中历练,要在严酷的反腐败斗争中提升,最终还要由人民群众来断定。加强党的执政能力建设,意义重大,任务艰巨,过程艰苦。     

领导干部问责制刍议

领导干部问责制是问责制的中心环节和切入点。近年来领导干部问责在实践和制度建设上均取得了进展,但问责主体、问责范围、客体界定、问责程序方面仍有完善的空间。为此,需进行相应的制度建设,以促进领导干部问责制适应现实的需要,并为中国特色问责制度的确立奠定基础。     

论抗日战争时期的云南铜业

抗日战争时期,中国国防用铜量急剧增加,但国土大部沦陷,云南成为抗战军需用铜唯一的供给地。国民政府经济部所属资源委员会与云南省政府共同组建"滇北矿务局","彻底管理"云南铜业,有效整合云南铜矿资源,把云南铜业完全纳入国家军事战略资源的范畴。国民政府在云南采取积极措施,使云南军需铜材产量大幅提升,保证了抗战的铜材需求,有力支持了中国人民的抗日战争。云南铜业的生产规模和技术也在抗战期间得到极大提升,加快了云南矿业现代化发展步伐。     

The Firm and Shaky Ground of Education for Sustainable Development

This paper employs academic and parable forms to evaluate critically the strengths and weaknesses, potentials and lacunae of education for sustainable development (ESD) and other sustainability-related educations. The meteoric rise to prominence of ESD is first briefly reviewed, as is the firm ground it now stands upon as an international and national educational priority. The remainder of the paper explores the shaky ground of ESD: the field's reliance on a goal, sustainable development, which, in its by-and-large continued embrace of the growth principle, is a myopic response to the Earth condition; the field's embrace of an instrumentalist conception of nature when such a conception itself feeds unsustainability; the overly skills/training orientation of ESD and its stunted engagement with a range of key aspects of the human-nature relationship; the failure of ESD to realize its original breadth and promise in its marginalization of the voice of peace, social justice, anti-discriminatory, indigenous and futures educators as well as that of sustainability educators in the South; its adoption of an anachronistic ‘steady state’ conception of nature. Finally, it is suggested that sustainability-related education would be enriched and enlivened by fomenting a dynamic complementarity between notions of transience and sustainability     

From Hawaii to Glasgow: The International Network for Learning and Teaching Geography in Higher Education (INLT) Five Years On

This paper examines and reflects on the activities of the International Network for Learning and Teaching Geography in Higher Education (INLT) from its founding at the Association of American Geographers' Annual Conference in Hawaii in 1999 to the post-International Geographical Congress workshop in Glasgow five years later. It provides a context and introduction to the following six papers, which resulted from the Glasgow workshop. It is suggested that, despite some of the proposals in Hawaii proving over-ambitious, several other projects have emerged and the INLT continues largely to meet the goals and purposes set out in 1999. Although the desire of the INLT to move beyond its Anglo-American and Australasian origins largely remains a challenge to be met, the INLT has established itself as a valuable forum for the geography higher education community to identify and reflect on similarities and differences in national practices, to engage in debate virtually and face-to-face on issues concerned with learning and teaching, and to bring geographers from different countries to work together on educational projects.
