在对攀西钒钛磁铁矿的调查基础上,综合考虑地质因素、社会经济效益、技术条件等方面构建攀西钒钛磁铁矿勘查综合评价指标体系,通过层次分析法确定各指标的权重,然后运用综合指数法对36个矿区内的钒钛磁铁矿勘查情况进行综合评价。结果表明,在攀西36个矿区中有10个处于暂不勘查阶段,主要集中在红格地区;17个处于需要勘查阶段,主要集中在红格和攀枝花地区;9个处于急需勘查阶段的矿区,主要集中在白马和太和地区;该评价结果真实反映了攀西地区钒钛磁铁矿勘查的实际情况。  相似文献

矿产资源勘查综合评价,目的在于从投入产出的角度对资源勘查工作的效益进行综合评价,为以后矿产资源合理规划、可持续开发利用以及合理高效监管提供决策依据。运用FAHP法,选取勘查程度、勘查单位储量投入资金、丰度指数、新增查明资源储量等动态、可比性的指标构建综合评价指标体系,建立FAHP模型,采用加权综合法将研究区划分为优、良、中、差4个等级,并对每个等级的矿区勘查效益予以综合评价,提出勘查决策。以攀西26个重点勘查区为实例分析,就研究区6种优势矿种开展研究,综合评价结果显示,雷波、金阳、宁南地区的综合评价指标值较低,符合实际勘查情况,今后应对这些地区勘查加大投入和加强管理,提高勘查成效,争取有新的突破。  相似文献

从矿产资源条件、技术经济条件及环境影响三个方面,构建了资源勘查布局评价指标体系。通过文献、理论及专家调研等多个角度筛选评价指标,然后利用德尔菲法、层次分析法确定指标权重及评价标准,运用单项和综合指标计算法得出各区块的勘查优劣度。在综合地质调查的基础上,以祁漫塔格金属矿集区为例进行了示范评价,矿集区内无不宜部署勘查的区域;有9个优先部署勘查区块,应按照地质找矿新机制的要求,重点优先部署勘查工作;6个可以部署勘查的区块,在着力解决制约因素后,可以部署勘查工作。  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

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

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

Abstract

California is one of the world's largest wine producers, yet it has exported only a small portion of its products. Many US wineries want to pursue opportunities in foreign markets but only a few are actually doing this successfully. Therefore, this study attempts to identify the successful practices of 12 California wineries that have achieved their financial targets and other export goals. A qualitative research design of in-depth interviews was employed. Results indicate that there are 5 major success factors, with the two most important being the foreign partner relationship and top management vision and commitment to exporting.  相似文献

A survey of agribusiness firms identifies characteristics associated with above average starting salary offers in the allied fields of agribusiness, agricultural economics, business, and economics. A complementary survey is made of students at Texas A&M University and University of Georgia. Results show that firms value work experience and leadership experience more than students do, whereas students value raising grade point average and interview preparation more than do firms. Students seeking a firm's maximum starting salary offer will need to enhance academic performance with substantial work experience and leadership experience.  相似文献
