京津冀地区位于我国北方农牧交错带前缘,坝上、燕山、太行山等地区是区域水源的主要发源地,同样是京津及华北平原的主要生态屏障。对京津冀地区矿产资源开发的生态环境影响进行评价,具有重要现实意义。本文根据京津冀地区矿产资源开发现状、规划空间布局和生态环境特点,综合运用GIS空间分析技术和生态风险理论,从矿产资源的空间布局合理性角度入手,分析京津冀地区矿产资源开发利用的生态环境影响,并以此识别区域内矿产资源开发的生态风险高发区和较高发区。结果显示,京津冀地区矿产资源开发空间布局与燕山、太行山山地水源涵养与水土保持区、坝上高原风沙防护区等生态功能区存在空间重叠,规模性的矿产开发会对区域内的水源涵养、土壤保持、生物多样性维护等生态功能构成持续性影响;高海拔地区的高强度开矿同样会加剧水土流失和荒漠化。天津市滨海区,承德市宽城满族自治县,邯郸市武安市等市县因密集分布了已有的矿产开发企业,并囊括了近期矿产资源开发的众多矿区,矿产资源开发的遗留性问题也比较突出,成为矿产资源开发的生态风险高发区。在生态影响分析基础上,本文提出了有针对性的空间差异性生态保护对策,以期为京津冀地区矿产资源开发布局优化提供技术支撑。 相似文献

基于GIS的县域经济差异与协调发展研究——以陕北地区为例 总被引:1,自引:0,他引:1
改革开放以来,陕北地区经济有了突飞猛进的发展,尤其是矿产资源的开发创造了巨大的经济效益。但近几年来,县域经济发展水平的空间差异逐渐扩大,已成为制约该区域经济发展的一大障碍。选取了人均GDP、地均GDP、人均地方财政收入、人均社会消费品零售总额、城镇化水平、在岗职工平均工资和农民人均纯收入7项指标,采用ArcGIS的IDW法模拟和分析了陕北地区经济空间格局,再采用量图分析法将陕北地区25个县级行政区分为先进、中等和落后3种类型,从县域的角度进一步分析经济水平的空间差异,最后对缩小县域经济空间差异和实现县域经济协调发展提出几点建议。 相似文献

NII ALLOTEY ODUNTON 《Natural resources forum》1977,1(3):285-297
The deep ocean floor represents the latest frontier of knowledge about global mineral resources. The ocean environment poses unique problems for mineral resource development - problems of resource assessment, adaptation of mining technology, and management of resources common to all of mankind. In the first of three related articles on the mineral resources of the ocean, Mr. Odunton assesses the current state of knowledge about the nature and extent of marigenous minerals. He examines the processes of formation, the composition, and the regional distribution of ferromanganese nodules, which represent the most promising of these minerals at present. Attention is also given to the considerations involved in the location, evaluation and exploitation of nodule deposits. Future articles will review ocean mining technology and the economic and policy issues involved in the development of ocean mineral resources. 相似文献

Two kinds of disparities pervade China and threaten its well-being. The first, regional disparities focus on levels of economic development, which vary considerably across China. The second is largely a corollary of the first, referring to mismatch in energy supply and demand, with some places suffering severe shortages while others are blessed with significant surpluses. Western China enjoys the dubious distinction of recording the country's lowest levels of economic development while, paradoxically, being blessed with plentiful reserves of energy and non-energy minerals. Turning those surplus resources to good account through transferring them to minerals and energy-hungry Eastern China is seen by policy-makers as something of a panacea. Not only will such a strategy significantly boost Western China's economic prospects, but it will eliminate the resource shortages currently constraining the East's vibrant growth. The issues of regional disparities, energy mismatches and transfers of these resources are discussed, with attention given to both spatial and time perspectives. The paper concludes with a cautious endorsement of the policy initiatives that promote the strategy of mineral transfers. 相似文献

Determining the optimal tax on mining 总被引:3,自引:0,他引:3
John E. Tilton 《Natural resources forum》2004,28(2):144-149
This article examines three arguments often raised in support of higher taxes on mining and finds them wanting: First, the wealth or economic rents associated with particularly rich deposits rightfully belong to the citizens of the host country. Second, mining companies should compensate the State and the public for their use of mineral resources, given the intrinsic value arising from their non‐renewable nature. Third, the division of the wealth created by mining is unfair. Too much goes to mining companies, and too little to the host country to promote economic development. It suggests instead that host governments should maximize the net present value of the social benefits flowing from their mineral sector. In practice, unfortunately, it is often difficult to know whether this objective is served by raising or lowering the level of taxation on mining. 相似文献

The distinction between an exploitable and a non-exploitable mineral deposit is dynamic, varying as a function of changing economic and technological factors. A conceptual framework is proposed: ‘reserves’ are restricted to known currently exploitable deposits; ‘known resources’ are reserves plus currently non-exploitable deposits; ‘total resources’ are known resources plus all deposits not yet discovered. The short-term inadequacy of some mineral reserves requites a policy of accelerated mineral exploration and rapid development of new exploration techniques. Future problems could be avoided if the nature of resources is recognized and new mineral extraction and processing techniques for lower grade and unconventional mineral deposits are developed. 相似文献

我国小型矿山的可持续发展战略 总被引:2,自引:1,他引:1
目前 ,我国小型矿山普遍存在着缺乏规划、设备简陋、工艺落后、管理和技术水平低、安全保障条件差、运销不畅以及职工素质低等问题 ,并由此造成的浪费资源、污染环境十分严重。当前 ,经济建设中 95%的能源和 80 %的原料依赖矿产资源供给 ,矿产资源探明的储量已显不足。进入 2 1世纪后 ,保证经济可持续发展的矿产资源更加不足 ,尤其是小型矿山要在 2 1世纪保持可持续发展成为一项非常艰巨的任务。 相似文献

社会主义市场经济体制下的区域规划 总被引:1,自引:0,他引:1
建立社会主义市场经济体制,就是要使市场在国家宏观调控下对资源配置起基础性作用。经济体制的改革对区域规划提出了新的要求.它决不意味着取消或削弱区域规划,而是要更好地发挥区域规划在发展区域经济中的宏观调控作用。区域规划是区域经济发展的超前研究,其价值在于具有比较准确的发展预见性,能够提出正确的发展方向和战略。区域规划的核心内容是指导资源优化配置,但它并不具有直接的资源流动机制,只能作为资源流动的信息机制。区域规划发挥宏观调控作用的必要条件是政府立法,公益性设施列入国家或地方的计划,在实施中争取社会舆论和社会投资的支持,对经济落后区域的开发采取国家扶持的政策。 相似文献
