现阶段地质勘查与开发模式探索     

魏润相 《陕西地质》2011,29(1):105-108

从计划经济到市场经济体制,从不同角度阐述了探矿权的取得和流转过程以及资源的开发和利用。有偿取得矿权,意味着探矿权有了财产权属性。资源储量成了矿政管理的基础,进而有利于加快勘查进程,提高勘查找矿的经济效益,促进勘查投资主体多元化的发展,使资源利用真正做到市场配置。  相似文献

莒县开展矿山储量动态监督管理工作的探讨     

厉运德  李成国  鹿星  浦玉敏 《山东地质》2011,(11):62-64

莒县有丰富的矿产资源,矿山储量动态监管工作是矿政管理工作的重要组成部分,但却一直落后于其他矿政工作。2010年以来,莒县循序渐进地开展储量动态管理工作,通过指标管理和现场实测核实等手段,取得了良好效果,提高了资源开发保护和综合利用水平。  相似文献

Systematic marine conservation planning in data-poor regions: Socioeconomic data is essential   总被引：1，自引：0，他引：1

Systematic planning for conservation is highly regarded but relies on spatially explicit data that are lacking in many areas of conservation concern. The decision support tool Marxan is applied to a reef system in the central Philippines where 30 marine protected areas (MPAs) have been established in communities without much use of biophysical data. The intent was to explore how Marxan might assist with the legally required expansion to protect 15% of marine waters, and how existing MPAs might affect that process. Results show that biophysical information alone did not provide much guidance in identifying patterns of conservation importance in areas where the data are poor. Socioeconomic data were needed to distinguish among possible areas for protection; but here, as elsewhere in marine environments, the availability of such data was very limited. In the final analysis, local knowledge and integrated understanding of socioeconomic realities may offer the best spatially explicit information. The 30 existing MPAs, which encompassed a small proportion of the reef system, did not limit future options in developing a suite of MPAs on a broader scale. Rather, they appeared to generate the support for MPAs that is obligatory for any larger zoning effort. In summary, establishing MPAs based on community-driven criteria has biological and social value, but efforts should be made to collect ecological and socioeconomic data to guide the continued creation of MPAs.  相似文献

The depletion of oil     

C.J. Campbell 《Marine and Petroleum Geology》1992,9(6)

The trend of previous estimates of the world's ultimate recovery of oil suggests a figure of 1650 BBO, of which 1438 BBO have been discovered and 978 BBO remain to be produced. Some large reported reserve figures are questioned. Importance is attached to the mid-point of depletion when rising production tends to give way to decline. The share of the world's supply coming from six Middle East countries is set to continue to rise from its 1986 low of 16% to as much as 50% by 2010, with the likely consequence of higher oil prices and serious political implications. The world is rapidly approaching a turning point when it has to face the consequences of an irreversible decline in oil production.  相似文献

Performance of community-based coastal resource management (CBCRM) programs in the Philippines: A meta-analysis     

Ronald J. Maliao  Robert S. Pomeroy  Ralph G. Turingan   《Marine Policy》2009,33(5):818-825

Community-based coastal resource management (CBCRM) is a major conservation and fisheries management strategy in the tropics. In this study, the performance of 16 CBCRM programs in the Philippines was assessed using a meta-analysis of eight indicators that represented the perceptions of local resource users. Overall, the CBCRM programs in the Philippines were perceived to have a significant positive impact. However, the performance of each of the indicators was mixed. Although the CBCRM programs were perceived to be effective in empowering the local fishing communities, their perceived impact on improving the state of the local fisheries resources remained limited. This highlights the importance of incorporating ecological and socio-economic considerations in setting fisheries management regimes.  相似文献
