找矿突破战略行动启动以来,华东地区掀起了新一轮地质找矿高潮,华东地区各省立足重点成矿区带,以深部找矿和覆盖区找矿为主攻方向,以整装勘查区为突破口,扎实推进找矿突破战略行动方案的实施,地质找矿多处取得重大进展,发现一批具有世界级储量的矿床,勘查成果超出预期,“358”第一阶段目标已基本实现。华东地区找矿突破工作虽然取得了可喜的成绩,但仍面临着一些问题和矛盾:地质勘查工作管理体制不顺、公益性与商业性工作概念不清、地勘单位体制机制改革滞后于发展需要、现有科技水平和人才培养机制不能满足找矿需求、现有矿业权管理政策不利于找矿突破战略实施的需要、地质勘查外部施工环境不顺畅、地质勘查(调查)项目资料汇交不及时、找矿突破中矿业权管理问题较多。为加强地质勘查工作、促进找矿突破工作提出几个方面的建议:进一步明确公益性队伍建设与定位;深化地勘单位体制机制改革,出台制度支持地勘单位体制机制改革;加大财政投入,保持地勘业持续稳定;改进地勘成果分配奖励办法,激发找矿积极性;进一步建立地勘人才培养使用激励机制;落实给国有地勘单位配置探矿权的优先政策,改革矿业权管理制度,促进技术与资本结合;制定地质找矿统筹规划;进一步强化勘查成果资料汇交责任;修改完善相关法律法规,优化找矿环境;出台地勘行业“走出去”工作指导意见。 相似文献

中央地勘基金的建立,是对我国多年来地勘管理体制和地勘投资体制的一次重大变革。它是当前条件下从国家层面运用新机制,着眼于解决国家急需矿种以及战略性地质勘查工作的带有产业资本性的生产基金。中央地勘基金着重用于重点矿种和重点成矿区带的前期勘查。中央地勘基金要实现国家确定的目标,应在服从、服务于《第二轮矿产资源规划》和《全国地质勘查规划》的基础上,加快编制地勘基金勘查规划;应不断完善地勘基金的运行机制,努力促进矿产资源勘查投入良性循环机制的建立。 相似文献

今天请大家来谈一谈中央和地方两级地质勘查基金如何协调联动的问题,主要有两个内容:一是中央和地方两级地勘基金如何形成相互协调的联动机制;二是中央地勘基金管理暂行办法经过一段时间运行后,如何进一步修改完善。这就涉及到中央和省级地勘基金怎么定位、怎么干的问题。针对这两个问题,听取大家的意见。 相似文献

促进商业性地勘工作发展,实现“商业跟进” 总被引:1,自引:0,他引:1
在贯彻落实地质找矿新机制“公益先行、商业跟进、基金衔接、整装勘查、快速突破”中,“商业跟进”是连接公益性地质工作与商业性地勘工作的关键。笔者通过近年来的调研,认为目前我国商业性地勘工作中存在着公益性地质工作不能有效地引导、支持商业性地勘工作的发展,商业性地勘工作投资不足,法制建设还不适应商业性地勘工作发展的需要,矿业权中介机构的建设不能适应市场发展要求,地勘单位改革进展与商业性地勘工作发展不相适应等问题,为此建议:加强公益性地质工作投入,减低商业性地勘工作投资风险;调整探矿权招拍挂政策,降低探矿权市场准入门槛;保障探矿权人投资权益;建实建强商业性地勘工作市场的主体。 相似文献

Abstract Cultures throughout the world are associating with the rivers. People depend upon the rivers and their tributaries for food, water, transport, and many other aspects of their daily lives. Unfortunately, human beings have not calculated the accurate lengths for the great rivers even today. The lengths of the rivers are very different in popular textbooks, magazines, atlases and encyclopedias, etc. To accurately determine the lengths of the principal rivers of the world, the combination of satellite image analysis and field investigations to the source regions is proposed in this paper. The lengths of the Nile, Amazon, Yangtze, Mississippi, Yellow, Ob, Yenisey, Amur, Congo and Mekong, with lengths over or close to 5000 km, were calculated using the proposed method. The results may represent the most reliable and accurate lengths of the principal rivers of the world that are currently achievable. 相似文献

软科学这一术语是70年代在国外提出的.然而30多年以来,它在国外不仅未得到普遍的承认,而且对软科学的定义也还未能达成大体上一致的共识.而在改革开放后的中国,出于决策科学化和民主化的需要,经过一些领导人的提倡和支持,特别是通过1986年召开的软科学座谈会及1994年召开的全国软科学工作会议,软科学事业得到了蓬勃的发展.据初步统计,截止1998年底全国共有软科学研究机构1224个,研究人员32655人,初步形成了一支较为强大的研究队伍,并取得了数百项覆盖多个领域的研究成果,为支持各级各类的决策发挥了一定的作用. 相似文献

The very long baseline interferometry (VLBI) Intensive sessions are typically 1-h and single-baseline VLBI sessions, specifically designed to yield low-latency estimates of UT1-UTC. In this work, we investigate what accuracy is obtained from these sessions and how it can be improved. In particular, we study the modeling of the troposphere in the data analysis. The impact of including external information on the zenith wet delays (ZWD) and tropospheric gradients from GPS or numerical weather prediction models is studied. Additionally, we test estimating tropospheric gradients in the data analysis, which is normally not done. To evaluate the results, we compared the UT1-UTC values from the Intensives to those from simultaneous 24-h VLBI session. Furthermore, we calculated length of day (LOD) estimates using the UT1-UTC values from consecutive Intensives and compared these to the LOD estimated by GPS. We find that there is not much benefit in using external ZWD; however, including external information on the gradients improves the agreement with the reference data. If gradients are estimated in the data analysis, and appropriate constraints are applied, the WRMS difference w.r.t. UT1-UTC from 24-h sessions is reduced by 5% and the WRMS difference w.r.t. the LOD from GPS by up to 12%. The best agreement between Intensives and the reference time series is obtained when using both external gradients from GPS and additionally estimating gradients in the data analysis. 相似文献

In this letter, we are trying to resolve the electromagnetic problem for the movements of the superconducting particles of the protoplanetary cloud in the magnetic field of Saturn. The force of levitation (Meissner-Ochsenfeld phenomenon) is introduced to the field of planetary science for the first time. It is shown from our theoretical analysis that rings of Saturn might have a superconducting origin, and rings might levitate within magnetic equator plane of the planet. 相似文献

根据残差二次型次小与最小之差进行整周模糊度确认的关键是差值的分布,只有得到了合理的差值分布才可确定合理的界值.文中基于原有的两种方法及这两种方法的不足,从理论上导出了满足条件的差值分布,并作了一定的说明. 相似文献
