从辽宁沿海经济带城市土地利用现状入手,选择土地投入水平、土地利用强度、土地利用效益和土地生态利用4个方面的10个评价指标,采用2008年的统计数据,运用层次分析和专家咨询相结合的方法确定了各评价指标的权重,在对评价指标进行无量纲化处理后,利用多因素加权分值法确定城市土地利用集约度。结果表明,研究区土地集约利用程度总体水平不高,区域空间差异较大,因此应进一步加大城市土地利用的挖潜力度,科学规划、合理利用,提高城市土地利用综合效益,提升城市土地集约利用水平。  相似文献

城市土地集约利用的影响因素及用地模式探讨   总被引:2,自引:0,他引:2  
区域发展、城市经济模式、城市集聚规模以及土地市场等因素对城市土地集约利用会产生很大的影响;在上述因素的影响下,产生了密集型城市用地模式和分散型城市用地模式的土地集约利用;不管哪种用地模式下的土地集约利用,都应该具有区域整体视野,采用适度的规模与合理的城市形态,注重土地的投入强度、使用强度以及利用效率,促使城市精明增长和紧凑发展。  相似文献

The primary objective of this paper is to examine changes in the level of output, prices and exports of major export crops resulting from the Structural Adjustment Program (SAP) in Nigeria. THere two main sources of data: the Central Bank of Nigeria (CBN) through its annual reports, Economic and Financial Review, and the Nigerian Federal Office of Statistics (FOS) through its Trade Summaries. Although the SAP led to appreciable increases in output and producer prices, its effects on exports were insignificant. The implications of these for the implementation of the program are explored.  相似文献

This paper aims to analyse and draw together results from similar studies in England, Switzerland and France which investigated farmers’ understanding of soil and compared it with that of scientists, researchers and advisors (collectively called scientists in this analysis). A range of methods were used across the three studies and different theoretical approaches, looking at forms of knowledge, local practice of knowledge production and conceptions of reality, were employed to explain the results. Despite the different contexts, methodologies and theoretical approaches in the three studies, the results reveal similar patterns of difference in farmer and scientist understanding of soil. In the English study, farmers demonstrate a ‘know-how’ form or intuitive working knowledge of soil while advisors rely on scientifically established forms of ‘know-why’ and seek to understand and explain soil processes. Similarly in the Swiss study farmers’ and scientists’ differing perceptions are directed and shaped by their respective aims, methods and context of work. In the French study, farmers and researchers are shown to have different conceptions of soil, they attribute different meaning to the same activities, and use different words and language to describe the same features. In all three studies understanding is shown to be cultural and contextual, as such an integrative theoretical framework is proposed.  相似文献

森林生物多样性评价模型的改进   总被引:3,自引:0,他引:3  
针对2002年的评价模型中的不足,提出了新的改进后的森林生物多样性变化的评价模型,并在我国第六次森林资源清查(1999~2003)资料的基础上,对1973~2003年我国森林生物多样性的变化进行了补充评价。评价结果表明:我国森林生物多样性的压力越来越大,压力指数由1973年的100,上升到2003年的199.10,上升了1.99倍;森林物种多样性总体的下降趋势已有一定幅度的改变,森林物种多样性指数增加了31.12%。森林生态系统多样性和森林生物多样性先逐渐上升,尔后又下降,第六次森林资源清查时又有所恢复,并分别上升了4.67个百分点和17.90个百分点。  相似文献

Abstract

In this paper, two approaches which are characteristic for Research & Development and Marketing departments are compared. First, R&D versus Marketing orientations are explained, then the major differences between them are presented. The integration of both approaches may improve competitive advantage of the food industry. Factors stimulating such integration are presented on the basis of data from real business circumstances. Innovation is regarded as a major source of competitive advantage of company. Therefore, integration in sensory methodology, that is commonly but differently used by R & D and Marketing departments, may contribute to the improvement of innovation practices and successful business performance. Finally, the role of consumer tests, oriented for marketing and product development, is illustrated.  相似文献

Although trust research has been extensive and substantial, the constitution and actual merits of trust in land use planning remain nebulous. What do participants of a local land use planning process actually mean when they say they trust the planning committee? How important is participants’ trust in the planning committee in shaping their perceptions of the planning process and their cooperation in it? To explore the everyday meaning of trust in the specific context of local land use planning, semi-structured interviews with the participants of a local planning project in Switzerland were conducted (n = 9). Based on these results, the constitution and the relevance of trust in the responsible planning committee among a wider circle of participants were assessed (n = 66). The results show that participants trust the planning committee if they perceive its members as competent, honest, open, fair, reliable, reciprocating, respectful and committed. Interestingly, a considerable part of trust in the planning committee hinges explicitly on whether the committee incorporates the personal interests of the participant. Trust is indeed vital to participants’ belief that a meaningful discussion and cooperation with the members of the planning committee is possible. However, trust is neither a guarantee for people's approval of planning decisions nor for their cooperation. One implication of the findings is that in order to evaluate trust-building practice comprehensively, it is necessary to first understand the specific everyday meaning of trust for ‘real people’ in real planning processes.  相似文献

Since the late 1980s, markets involving agricultural land have emerged in the Socialist Republic of Vietnam. One major reason is that collective farms, previously a central feature of the country's political economy, ended. And a major reason for that was villagers' everyday politics gnawed the underpinnings of the collectives until they collapsed. Rural households, for the most part, wanted to farm separately. Today they do. Land is not privatized, however. Farming households have land use rights, not ownership. This tempers markets, as do other conditions arising from contending schools of thought in Vietnam about how land should be used, distributed and regulated.  相似文献

This project was initiated to promote conservation agriculture (CA) in Tanzania so as to improve the food security and rural livelihood of small- and medium-scale farmers through the scaling-up of CA as a sustainable land management (SLM) tool as well as increasing the numbers of SLM-CA farmer field schools (FFS) in communities. The project had two phases from 2004 to 2010. It was funded by a Government of Germany trust fund and implemented by the Food and Agriculture Organization of the United Nations (FAO) and the Ministry of Agriculture in Tanzania. The project pilot districts include Arumeru (Arusha and Meru Councils), Karatu, Babati, Hanang and Moshi districts. CA has been shown to offer positive elements that could contribute to fighting hunger and poverty.  相似文献

The paper proposes a materialist–utopian perspective for explaining the persistence of community in the Andes by drawing upon Lacanian theory and the thought of the Peruvian Marxist José Carlos Mariátegui. What characterizes the Andean comunidad are not notions of belonging and identity, but the existence of a fundamental antagonism (what I call the ‘Real of community’). The argument unfolds ethnographically. Usibamba, a peasant comunidad in the central Peruvian Andes, is known as a highly egalitarian and disciplined comunidad. However, a disjunction exists between deep‐seated aspirations of justice and egalitarianism and the particularistic interests of families and individuals. This disjunction manifests itself in a contradictory, schizophrenic regime of discipline and negotiation that produces ‘split subjects’. Desiring development and the staging of theatrical performances of egalitarianism enables Usibambinos to deal with this disjunction and to present an image of unity and determination. I conclude that the comunidad persists through ‘impossible political acts’ brought about by a residual but growing category of landless comuneros who constitute ‘the part of no part’, the uncounted or unnamed.  相似文献
