21世纪矿业应向后工业发展势态倾斜--适者生存和可持续发展

“后工业”（post-industry)是知识经济或曰“新经济”的发展时代。这个时代的自然资源和一般劳动力资源,包括矿产资源在国民经济和社会发展中的基础地位逐渐为知识产权、市场网络、信息、创新环境等后天获得性资源,以及为创新人才的新“认知”（recognized intellect,RI)所代替。然而,据矿产资源分布及其成矿既具有一定的全球统一性又有区域的特殊性,以及不同国家（地区）对矿产资源勘查程度的不均衡性,特别是矿业活动与其他产业性质的不同,如何能按不同国家（地区）的具体发展状况,做好21世纪矿业向“后工业”发展势态的倾斜,达到适者生存和矿业可持续发展的目标是当代探讨的重大问题。在概括阐述了21世纪矿业发展势态、矿业活动特点及其自然属性的基础上,提出了矿业可持续发展的地质勘查和矿业活动决策支持系统的模拟,以及对当前紧缺铜矿资源可持续发展的新“认知”。     

安徽矿业循环经济范式初探

安徽是矿产资源大省,要把资源优势转化经济优势,必须运用循环经济的新范式,结合安徽实际,根据科学发展观的要求,实施矿业可持续发展战略。本文还提出了关于用循环经济的理念来促进安徽矿业的几点政策建议。     

土壤污染地球化学标准及等级划分问题讨论

全国多目标区域地球化学调查发现有害元素广泛分布引起极大关注。土壤污染将长期危及生态系统和人类生存安全。制定土壤污染等级标准十分重要。国家土壤环境保护标准体系中,土壤污染等级标准是针对调查发现的污染进行量度划分,土壤环境质量标准是依据污染对环境影响程度确定临界值,土壤污染评价标准是针对存在问题进行科学研究的指标。土壤污染等级采用统一的分级标准,划分为国家级、流域级、省级和地市级。标准制定是一个由局部到全局的认识,又由全局到局部的决策过程。在多目标区域地球化学调查基础上首先制定土壤污染标准及划分污染等级是笔者的主导思想。     

地质公园建设在旅游发展中的作用

地质公园建设不仅可开发地学旅游新产品,拓宽地学旅游市场,加强对地学知识的科普宣传教育,满足游客日益增长的求知需求,不断提高人们的生活品位,还具有指导地质遗迹景观区的管理和保护工作,促进以旅游为龙头的地方经济快速和可持续发展的重要作用和意义。     

云南地区房屋建筑的震害矩阵

自1992年4月23日云南孟连西中缅交界6.7、6.9级地震始,地震部门对云南地区的破坏性地震进行了现场灾害调查和经济损失评估。1992~2003年,云南地区共发生50次破坏性地震,积累了丰富的震害资料。本文根据云南地区的主要建筑结构,统计分析了50次地震不同烈度区的破坏比、损失比和震害指数,给出了房屋建筑的震害矩阵。     

A preliminary case study of potential ceramic raw materials in the Aileu area of Timor Leste

The newly independent country of Timor Leste is located in the eastern half of Timor Island (Indonesian archipelago). Geological studies of the country’s mineral resources and extractive activities are practically non-existent. There is evidence of the exploitation of ceramic raw materials at outcrop level and two small brick kilns, nowadays inactive, in the Dili and Aileu areas. Near Aileu, there are light-coloured silt-rich deposits, interpreted as overbank deposits, interbedded with ancient river terraces (post-Pliocene) overlying metamorphic bedrock. These sediments are the subject of this study, which encompassed geological mapping and preliminary characterisation. Tectonically, the area is a graben, preserving alluvium and colluvium deposits. Five channel samples representative of the silt-rich deposits were collected. Semi-quantitative mineralogical analysis shows that the samples are made of illite, quartz and kaolinite clays, with accessory illite/vermiculite interstratified minerals and K-feldspar. The chemical data show agreement with the estimated mineralogical composition. The grain size distribution points to a silt-dominated assemblage. Most samples have a satisfactory extrudability but deficient moulding properties. After firing, the sampled raw materials form a final product with possible ceramic capability for whiteware production.

Maquiladora Myths: Locational and Structural Change in Mexico's Export Manufacturing Industry

Trends in location, labor force, and procurement practices in maquiladoras are examined using recent data sources. A growing proportion of maquiladoras are selecting interior locations, south of the borderlands. Once dominated by young women, the labor force is rapidly approaching gender parity. While far below prevailing rates in the United States, maquiladora wages are comparable with equivalent manufacturing sectors in Mexico. Majority ownership of maquiladoras is split almost evenly between Mexico and the U.S., however, maquiladoras have failed to develop domestic sources of materials and parts and remain dependent on imported material inputs. As the North American Free Trade Agreement is phased in, the regulatory environment of maquiladoras will change but their role as low cost assembly specialists will persist.     

Factor analysis of trends in energy and metals production and consumption in developed and developing countries

This paper presents a methodology used to combine energy and mineral market variables between Less Developed Countries (LDCs) and Developed Countries (OECD) over the past 24 years (1966–1990). LDCs include all countries, except OECD and central planned economies (CIS) and other countries in Eastern Europe. This period permits a comprehensive view of the impact of the energy crisis and the changes in economic growth patterns, correlated with changes in trends of production and consumption of energy and metals in both country blocs. This complex relationship was evaluated by a factor model of consumption and production variables using the aluminum, copper, lead, and zinc industries. The following variables are used in the factor model: export dependence, geographic concentration of mining production, geographic concentration of refined demand, geographic concentration of refined production, import dependence, refined demand growth, stability of demand, income elasticity of refined demand, price stability, intensity of use, and intensity of energy. The model for all commodities shows that the factor scores projections for LDCs and OECD blocs depicted a clearly divergent trend after the two oil shocks (1973–1979), when the intensity of energy variable presents high loading in the factor. The results are in substantial agreement with findings that the demand for energy, as well as for metals, is growing more rapidly in LDCs than OECD.
