Guidelines for international data collection and resource assessments and analyses

The ever-increasing world interdependency required to provide the basic energy and mineral commodities needed by society, has created a need to assess, on a common basis, the location, number, and quality of deposits of natural resources. In order to evaluate and compare the resource potential of any area, two major factors must be considered: (1) the type of commodity being evaluated and (2) the specific parameter (reserves or resources) which is being defined. Each commodity or parameter being studied requires a separate methodology for analysis and different basic data. Porphyry copper deposits must be treated differently from stratabound copper deposits or massive sulfide deposits of copper. Similarly, oil and gas deposits associated with stratigraphic traps must be treated differently from those associated with salt domes. Resource assessments attempt to estimate the aggregate resource potential of an area whereas resource analyses attempt to define the specific characteristics of the individual occurrences which comprise the aggregate resource potential. Assessment programs may range from a national inventory of known deposits and occurrences to detailed studies which require an extensive integration of geological, geochemical, and geophysical data. Examples of national inventories are the small mine inventory of Bolivia and presently operating resource programs in Turkey and Argentina. Detailed programs of assessment include the AMRAP (Alaska Mineral Resource Appraisal Program) program and studies in the Coeur d'Alene district and Ely, Nevada. Worldwide resource analysis is a rapidly expanding field of endeavor necessitated by the need to more clearly define the characteristics of known deposits and to provide quantitative estimates of hypothetical and speculative resources. Studies presently underway deal with the development of search and occurrence models, field size distributions of energy resources, tonnage and grade relationships of mineral deposits, the zone of influence of exploratory drill holes, and models of the exploration process.This paper was presented at the International Geological Correlation Program (IGCP) Project 98 entitled Standards for Computer Applications in Resource Studies held at Loen, Norway, September 27–October 1, 1976.     

乡村旅游文化资源开发研究

新疆尉犁县双峰岭金矿床特征及资源潜力分析

双峰岭金矿床处于塔里木板块东北缘的库鲁克塔格陆缘地块,北邻艾尔宾晚古生代残余盆地,南为塔里木中央地块;金矿体严格受地层岩性、韧性剪切带、脉岩三重控制.矿石类型有石英脉型和石英脉蚀变岩复合型;蚀变主要有绿泥石化、褐铁矿化、黄钾铁矾化、绢云母化、碳化和碳酸盐化、硅化等.金矿成矿物质主要来自变质热液,由于矿体受断裂构造控制,...     

中国地震网格试验系统中资源管理与作业调度研究-资源管理和作业动态分配模型ProRMJS的建立me

通过分析与研究建立资源管理和作业动态分配ProRMJS模型,解决了中国地震灾害仿真网格试验系统（CEDAGrid）中网格科学计算平台在初期建设中存在的一些资源管理方面的问题. 针对网格科学计算平台默认各个计算节点均能提供计算服务的问题,ProRMJS通过ldquo;计算池rdquo;这一虚拟组织为调度器分发作业提供支撑;而调度器则根据计算池中各个节点的计算能力和状态,动态分配任务,这样就保证了计算平台的稳定性. 针对默认各个计算节点均能完成任务的问题, ProRMJS通过监控各个节点所负担作业的运行进度和设定作业时间阈值来管理作业运行. 对于各个节点计算能力大小的区别, ProRMJS通过对各个节点计算性能的权值量化,实行按ldquo;需rdquo;分配作业. 对各个节点计算性能的权值量化, ProRMJS是通过综合考虑各个因素对机器计算能力大小的影响后通过加权计算的方式完成的,从而提高了整个计算平台的工作效率. 最后通过实现地震应力触发科学计算实例验证了方案的有效性,为网格技术在地震领域内的进一步应用作了有意义的探索.      

基于小比例尺矿产资源遥感监测的应用研究

矿产资源开发给矿山环境带来很多问题,怎样利用遥感技术来对矿产资源开发进行监测,实现矿产资源的可持续开发,是摆在我们面前的一项难题。本文采用1∶50 000小比例尺遥感影像图,以临汾市乡宁调查区为例阐述了对矿产资源遥感监测的技术路线和工作方法。并通过数据对比,分析了监测结果,为当地土地管理部门提供矿产资源开发的建议,为该技术的推广应用奠定了基础。     

基于城市竞争力的资源型城市空间布局研究

在总结已有的界定原则基础上,对中国资源型城市进行了界定和划分,确定了51个地级市及以上资源型城市,并从地理空间和城市竞争力的角度分析了这些城市的在空间位置上的分布规律。研究发现,我国资源型城市大多分布在中西部和偏北地区,而城市竞争力排名靠前的城市,无论在资源类型还是地理区位条件上都有着很明显的共性。可见地理区位因素隐藏在资源禀赋背后,对城市发展有着显著的影响。     

Using Information Technologies for Interactive Learning

Abstract

Experiences in designing, offering, and evaluating joint senior undergraduate course assignments in resource and environmental management on two different occasions, which connected students in two universities in British Columbia and Ontario, are documented. The shared assignments provided students with experience in group work and consensual decision making, and allowed them to use a mix of information technologies (e-mail, chat rooms, the Web, video conferencing). The undergraduate students rated very highly the experience with information technology but found some aspects of a collaborative learning approach to be challenging. The course was less successful than had been anticipated in highlighting different regional perceptions and perspectives regarding resource and environmental problems and solutions. Clarification of objectives and expectations, more attention to allocation of time, and consideration of computer access and assistance would improve the effectiveness of the courses.     

Partnering between a geography department and a community initiative to provide a wind resource assessment for the Blueskin Bay region,Otago, New Zealand

This paper explores the partnership between a community group and a geography department to assess the wind energy potential of the Blueskin Bay region in southern New Zealand. The partnership has provided opportunities for research and is of strategic importance. Year‐long wind observations and numerical modelling have revealed that the hills surrounding Blueskin Bay show potential for wind energy generation. Despite challenges for both parties, the university–community partnership has allowed a successful research platform to be established.     

中国煤炭资源供应格局演变及流动路径分析

利用1949—2008年的相关统计数据,分析中国煤炭资源供应格局和流动路径,结果表明:(1)国家政策变动对中国煤炭资源消费规模影响深刻,每一次政策变化都会造成能源消费规模的波动,近年来强烈的能源需求使得我国煤炭供应不得不面临进口的现实;(2)受能源需求和资源禀赋的双重压力,大规模、跨区域、长距离的煤炭运输成为我国能源运输体系的重要特征;(3)尽管煤炭运输方式在向铁路、水路和公路组合并用的多元化发展,但仍然不能满足旺盛的能源需求,煤炭运输瓶颈始终存在,变输煤为输电是缓解当前煤炭运输困难的一个途径。
