原中央地质调查所、中央研究院地质研究所和资源委员会矿产测勘处都曾为中国地质事业的发展作出过重要贡献。但是,在1949年以前总体地质人员少、部门分散。为解决解放初期矿产资源紧缺和地质人员短缺的矛盾,1950年8月经政务院批准成立了中国地质工作计划指导委员会,及其领导下的矿产地质勘探局、中国科学院地质研究所和古生物研究所,开始了地质界一元化的机构改革。1951年5月7日新成立的3个机构开始运行,在运行初期实行地质研究人员的双重身份制度,即在矿产地质勘探局为技正,在研究所为研究员。1952年6月初步确定了各单位内设机构和人员,同时各专业地质队陆续成立,开始了人员的再次分配。1952年8月地质部成立,矿产地质勘探局,逐步转变为地质部的不同部门,地质研究所和古生物研究所全面接受地质部的领导。原中央地质调查所在这次变革中人员被分散到新成立的3个部门和有关单位,原来的内设机构被彻底分解,事实上被撤销。原中央地质调查所在长期实践中形成了以调查为本、调查与研究紧密相结合的研究风格和特色,在解放初期,不论是矿产地质勘探局还是中科院地质研究所和古生物研究所都围绕国家急需的矿产资源开展工作,都谈不上与中央地质... 相似文献

Adaptive capacity and its assessment 总被引:4,自引:0,他引:4
Nathan L. Engle 《Global Environmental Change》2011,21(2):647-656
This paper reviews the concept of adaptive capacity and various approaches to assessing it, particularly with respect to climate variability and change. I find that adaptive capacity is a relatively under-researched topic within the sustainability science and global change communities, particularly since it is uniquely positioned to improve linkages between vulnerability and resilience research. I identify opportunities for advancing the measurement and characterization of adaptive capacity by combining insights from both vulnerability and resilience frameworks, and I suggest several assessment approaches for possible future development that draw from both frameworks and focus on analyzing the governance, institutions, and management that have helped foster adaptive capacity in light of recent climatic events. 相似文献

Human migration may negatively impact biodiversity and is expected to increase in future, yet the phenomenon remains poorly understood by conservation managers. We conducted a mixed-methods investigation of a contemporary migration of traditional fishers in western Madagascar, a country which has been expanding its protected area system through the establishment of both strict and multiple-use sites, and critically evaluate different models of marine protected area in light of our findings. Interviews with fishers in major destination areas revealed that most migrants come from southwest Madagascar, use non-motorised vessels, and principally target sharks and sea cucumbers. Drivers of the migration include both push and pull factors (i.e. declining resource availability in areas of origin and the continued availability of lucrative resources for export to China). Traditional fisher migrants cause limited social conflict with residents and a number of environmental problems in destination areas: however artisanal fishers with motorised vessels probably represent a greater threat to marine resources than migrants, due to their greater harvesting capacity. We suggest that multiple-use arrangements may be more appropriate than strict protected areas in both source and destination areas, because they integrate the interests of migrants rather than marginalising them: however seascape-scale management provides the best approach for managing the threats and opportunities provided by the migration at the appropriate scale. 相似文献

Political culture is an attractive concept to characterize the specific preferences regarding politics in different political communities. However, it is a blurred concept because of the confusion between patterns of individual values and collective culture at the one hand, and the disputable separation between orientations and practices at the other hand. This contribution explores the potential of Cultural Theory, also called the Theory of Sociocultural Viability, to analyze political culture. This theory postulates the existence of four viable ways of life, which are patterns of social interactions and rationalizations reinforcing each other. Each way of life offers a partial explanation of reality and therefore reaches out for cultural allies who can compensate for its weakness. Such an alliance, generally between two ways of life, can be quite stable and therefore determines to a large degree the nature and the stability of the political institutions of a country. The political culture of a political community can be characterized by the proportion of adherents of each way of life (its regime), and by the predominant alliance of two ways of life. 相似文献

This article broadly positions the successful establishment of the field of French tropical geography in the immediate postwar period against developments stemming from a longer history of French colonial engagement in Africa, Asia and South America, and clarifies the seemingly late timing of, and paradoxes involved in, the creation of a body of French scientific knowledge about the tropics. Colonial scientific research did not develop in France until the end of the nineteenth century. However, the colonial geography appearing at this time did not rely on fieldwork but, rather, catered to the demands of the business class for overseas expansion and to public curiosity. Even while the medical geography of tropical areas and knowledge of tropical soils and ecology progressed greatly between 1900 and 1940, there were still only a few French geographers working in the tropics. With the advent of the Second World War, when “big science” appeared in France and its colonial empire, the number of French geographers involved in tropical research grew rapidly. The field of tropical geography built up by Pierre Gourou was a synthesis of approaches developed in South America, Africa and Indochina. Although it soon came under strong criticism for its pessimistic view of prospects for industrialisation and urbanisation in the tropics, it seduced French geographers because it matched the contemporary interest in zonality and relied on a genre de vie analysis of, typically, rural areas. Thus, the postwar blossoming of tropical geography shaped by Gourou was more a response to various internal dynamics within French geography than an exercise in imperialism. Its demise was not due to the eclipse of French colonialism but, rather, its inability to deal with the modernisation of tropical societies. 相似文献

Forest‐transition theory suggests that economic development eventually leads to forest recovery, but there is great uncertainty about the existence, the characteristics, and the mechanisms of forest transitions that might be occurring under current socioeconomic conditions. A case study in a small region of highland Mexico finds agricultural abandonment and forest regeneration, but also forest degradation due to woodcutting. A discussion locates those findings in the international political economy of agriculture and emigration in Mexico, which are substantially different from the conditions associated with forest recovery in developed countries. Although regional forest transitions are possible in marginal agricultural areas such as that studied here, their environmental implications depend on the evolution of social institutions coordinating rural people's environmental actions. 相似文献
