京津冀地区矿产资源开发的生态环境影响研究   总被引:1,自引:1,他引:0       下载免费PDF全文
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

The concept of value is central to mineral economics as it is all branches of economics. In the minerals sphere particular problems are posed for a theory of value by, firstly, the non- renewability of mineral resources, secondly the substantial effort that must be made to convert a mineral into a useful product, and finally the perception of minerals, both economically and symbolically, as peculiarly national forms of wealth. Some thoughts are offered on different approaches to mineral resource valuation and on the frequently conflicting principles of exploitation to which these various approaches give rise.  相似文献

Governments of developing countries may obtain ownership participation in national mining projects in the hope of receiving greater policy control over, financial rewards from, and information about such projects. These objectives could be achieved by using their sovereign authority to tax, regulate and monitor projects more effectively. The principal problem is likely to be the administrative inability fully to enjoy rights that they lawfully possess. As such projects are nearly always controlled by foreign entities, and involve the exploitation of irreplaceable mineral wealth, they may engender feelings of suspicion and hostility. Government participation may sometimes be necessary to mitigate those feelings and to lead to more stable and successful projects. If these political objectives are fully recognized, then government participation may be structured so as to minimize any detrimental effect it might have on the fiscal and financial structure of the project. It may also prove to be a vehicle for future participation by private local interests, thereby eliminating the alien enclave feature generally characteristic of such projects.  相似文献

In India, the mineral resource inventory and the production of a large number of important minerals have registered significant increases during the last few decades. Yet the country continues to be a net importer of many high value and scarce minerals and metals, like gold, diamond, and several base metals. Exploration and development of the resources of these minerals are technology- and capital-intensive. To bring technology and capital through foreign direct investment (FDI) into the Indian mineral sector, it is imperative to lay stress on: accurate resource estimation and categorization, as well as realistic projection of the true values; rationalization of legislative measures based on R&D studies and reorganization of the implementation machinery; conducive tax structure; notification of acts and rules applicable to offshore mineral resources; time-frames for granting licences and leases; encouragement to labor productivity by rationalizing labor laws; reforms in the monetary system to increase market competitiveness of Indian minerals; and judicial reforms. FDI in the Indian mineral sector is important to firm up the knowledge-base of mineral resources and their optimum exploitation.  相似文献

This article outlines the problems related to the exploitation and allocation of undersea resources. The nature and accessibility of undersea petroleum supplies and metalliferous nodules are described in terms of the existing and prospective future economic constraints. Since the majority of such resources lie outside national jurisdictions, their ownership has recently become a major source of international conflict. The character of that conflict is explained, and the prospective solutions under international law are identified. Unilateral action on the part of countries possessing the requisite technologies to exploit these resources is viewed as the most probable near-term outlook, even though it may not satisfy very many aspects of international equity.  相似文献

Mineral resources represent an integral component within a country’s economy. Despite the fact that the need for raw materials undergoes continuous growth–especially in countries which experience industrial upswing–proper measures to secure the access to domestic mineral resources in the long term have only been applied marginally in a large number of states. This lack of future-oriented legal frameworks–referred to as ‘Minerals Policies’–might lead to a diversity of sectoral problems (eg. dependency on certain raw materials imports). Based on data analysis and subsequent demand forecasting comprehensive national Minerals Policies can be derived in order to anticipate emerging issues and to achieve optimum sustainable management of domestic geological resources. The necessity of such concepts is illustrated by the example of Romania focusing on non-energetic mineral resources.  相似文献

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

矿产资源开发对促进国民经济的发展具有重要的作用,但与此同时也带来不少环境问题,如破坏土地和生态环境,在矿石采选冶中产生“三废”对周围环境严重污染,破坏水资源平衡,引发地质灾害等。因此,现在必须高度重视并加强矿产资源开发中对环境的保护与治理,使矿产资源开发与矿山环境保护协调发展。首先,应制订并实施各地区的矿产开发规划,根据环境容量等调整矿业布局和矿业结构,严格对矿山环境进行监测、监管;其次,应加强对矿山环境的调查和评价,加强矿山环境保护的科技研究,提高矿山环境防治技术水平并加速技术推广;最后,应加强矿山环境保护的宣传教育,使矿山环境在全体公民的参与和监督下得到有效的保护。  相似文献

While the Convention on Biological Diversity (1992) introduced a new and progressive outlook on conservation, the South African government has failed to produce a comprehensive legal body of legislation to give effect to its varied obligations. Inconsistency and incompleteness of regulations governing wildlife conservation in conjunction with the failure to implement objectives to conserve wildlife through restricted exploitation with the political, social and economic motives of community conservation must be seen as major contributions to failed conservation goals. This paper analyses post-apartheid conservation laws and policies and argues that current plans for people-centred approaches to natural resource management programmes have been unsuccessful in operationalizing policy goals of biodiversity conservation and sustainable development into transparent plans for implementation. In fact, legal instruments and implementation plans seem to focus on the benefit-sharing components of community participation and therefore fail to address important issues of resource exploitation. It is suggested that where communities are expected to take part in the management of wildlife resources, the responsibility for sustainable wildlife management must be linked to the benefit-sharing instruments of the programmes. However, these would not deal with 'outsiders' like poachers and poaching driven by commercial interests. The paper proposes a model that allows communities to take control over wildlife resources.  相似文献

Projected increases in demand and thus increasing metal prices have brought the exploration and exploitation of marine mineral resources back into focus. The Atlantis II Deep, located in the central Red Sea between Saudi Arabia and Sudan, is one of the largest marine sulfide deposits known, with high concentrations of metals such as zinc, copper, silver and gold. However, little is known about the economic potential of marine minerals as well as the legal constraints. Our geological assessment shows that the deep is similar in grades and scale to large land-based deposits. Its economic potential is far from negligible. The total present value of possible gross revenues for the four metals zinc, copper, silver and gold ranges from 3.03 to 5.29 billion US$, depending on the assumptions made concerning future price development, mass calculation and discount rate. From a legal perspective, a general duty to cooperate in the exploration and exploitation of non-living resources located in disputed maritime areas is identified in both customary international law and in UNCLOS. It is submitted that a joint development agreement is one means of ensuring compliance with this duty in general and in the case of the Atlantis II Deep in particular.  相似文献

Political-economic events of the 1970s brought mineral resource appraisal to the focus of national policy. Estimates of and methodologies for mineral resources appraisal were scrutinized, revealing deficiencies in method and data and fostering considerable debate about the credibility of estimates and about preferred methodology. Since credibility can be increased through the acquisition of additional geoscience information, questions regarding methodology have more than one formulation and therefore more than one correct solution, depending upon the expected value of additional information and the conditional losses of relevant policy options. When existing information is meagre and the expected value of information is high, the optimum decision may be to defer all policy options until after the acquisition and analysis of- additional information. Decision theory offers an analytical framework that is sufficiently generalized to provide answers for highly varied circumstances of geoscience and resource information and policy issues. Our ability to perform any such analysis is limited by inaccuracies in both geologists' estimates of undiscovered mineral resources, and in economists' calculations of conditional losses of policy options for each of the relevant states of mineral resources.  相似文献
