塔里木盆地是我国最大的盆地,面积达33.7万平方公里。塔克拉玛干大沙漠位于其腹地,是世界上第二大沙漠,其流沙面积占整个沙漠的85%。大量资料表明,该地区油气蕴藏量极为丰富,已引起世界瞩目。塔里木盆地石油勘探的突破,为我国石油工业持续稳定的发展提供了现实的接替地区。九十年代石油工业重点发展将再次西移。搞好西部沙漠地区的油、气勘探开发工作,对搞好石油工业的战略接替、保持油气产量的稳步增长,具有十分重要的意义。 本文所指的石油开发设备,包括石油钻采机械、发电、配电、运输、工程机械和通讯等开发塔里木石油有关的各类设备、装置及生活设施。为了能很好地开发塔克拉玛干大沙漠的油气资源,首当其冲的问题是保证设备 相似文献

针对配合国家五部委开展油气勘探开发涉及环境敏感区联合调研中所发现的问题,如油气田企业涉及的环境敏感区及生态保护红线类型复杂、数量众多,其划定的科学性,涉及该类地区油气生产设施强制退出缺乏有力法律法规支持等,提出进一步评估、梳理现有环境敏感区和生态保护红线的范围和功能分区,区别对待、加强环境敏感区禁止情况的针对性,降低环境敏感区内油气设施退出的盲目性,加强油气资源探、采矿权批准的严肃性,分级管控、建立战略储备勘探及分级开发机制等对策建议;并对油气田企业提出加快摸清环境质量现状,坚持"在保护中开发,在开发中保护",进一步加大对国家油气勘探开发战略评估提供技术支持的重视力度和参与力度,加快与地方政府就生态保护红线问题沟通对接,积极争取纳入地方政府正面清单管理,加快建立并完善油气生产及设施建设的基础数据库,建立生态保护红线管理信息系统等建议。 相似文献

本文采用改进的BCR三步连续提取法对河北某食道癌高发地土壤中钙、镁进行了形态分析及提取序列的研究。实验表明:该地区土壤中镁主要以残渣态形式存在(占总量的83.66%-88.36%),钙则受提取序列的影响很大,在第一提取序列中,以酸溶态为主(74.11%-83.38%);第二提取序列中,以有机物结合态为主(78.12%-97.17%);第三、四提取序列中,以氧化物结合态为主(87.49%-103%)。提取剂的加入顺序明显影响到钙的各个形态的真实含量。 相似文献

A Suggestion for an Improved Vegetation Scheme for Local and Global Mapping and Monitoring 总被引:1,自引:0,他引:1
Jonathan M. Adams 《Environmental management》1999,23(1):1-13
The next stage in the process will be to obtain the views of as many people working in as many different fields as possible,
to see whether the proposed scheme suits their needs and how it should be modified. With a few modifications, such a scheme
could easily be appended to an existing land cover classification scheme, such as the FAO system, greatly increasing the usefulness
and accessability of the results of the landcover classification. 相似文献

ABSTRACTConcepts of ecological and environmental democracy seek to reconcile two normative ideals: ensuring environmental sustainability while safeguarding democracy. These ideals are frequently conceived as being in conflict, as democracy is perceived as too slow and cumbersome to deliver the urgent large-scale collective action needed to tackle environmental problems. Theories addressing the democracy-environment nexus can be situated on a spectrum from theories of ecological democracy that are more critical of existing liberal democratic institutions to theories of environmental democracy that call for reforming rather than radically transforming or dismantling those institutions. This article reviews theoretical and empirical scholarship on the democracy-environment nexus. We find continued theoretical and empirical diversity in the field, as well as vibrant debates on democratising global environmental politics, local material practices, and non-human representation. We argue for stronger dialogue between environmental political theory and empirical, policy-oriented research on democracy and sustainability, as well as further exploration of complementarities between ecological and environmental democracy. We identify four main areas of challenge and opportunity for theory and practice: public participation and populism; technocracy and expertise; governance across scales; and ecological rights and limits. 相似文献

The use of organic farming technologies has certain advantages in some situations and for certain crops such as maize; however, with other crops such as vegetables and fruits, yields under organic production may be substantially reduced compared with conventional production. In most cases, the use of organic technologies requires higher labor inputs than conventional technologies. Some major advantages of organic production are the conservation of soil and water resources and the effective recycling of livestock wastes when they are available. 相似文献

A debate is still open on issues of waste to energy methodologies aiming to answer to questions of particular relevance, such as whether the concept of SRF/RDF production can be applied directly to MSW through the Mechanical–Biological Treatment (MBT) process, when selective collection acts as a virtual pre-treatment of the same, or if the use of SRF/RDF as alternative fuel in cement kilns is the most sustainable solution. In this study, two scenarios were analyzed and compared: (a) the use of SRF in a new dedicated thermal plant for electricity production and (b) the use of SRF as an alternative fuel in an existing cement plant. The comparative assessment was based on principles of Sustainable Waste Management embracing technical and cost issues, environmental protection, industrial ecology and symbiosis. The application of SWOT analysis showed that the use of SRF in cement kilns is more sustainable compared to its use in a new dedicated plant for electricity production. 相似文献
