伴随世界海洋竞争的日益激烈,以及深海战略性资源争夺的不断加剧,深海资源开发已经引起我国政府的高度重视,积极部署,重点谋求在深海科技领域首先实现突破。山东省是海洋资源大省,深海战略性资源十分丰富,随着海洋科技的发展,面对海岸带地区和近海资源环境承载力的日益饱和,海洋资源开发必将呈现出由近海向远洋、由浅海向深海的发展趋势,开发深海大洋战略性资源是破解山东省社会经济发展资源瓶颈的重要途径,发展深海大洋经济是海洋经济的发展方向。 相似文献

辽阔的海洋是人类资源的宝库,尤其是海洋深处蕴含极为丰富的矿产和生物资源。随着人类对资源的需求与日俱增以及陆地资源的开采耗竭,深海海底这一特殊区域无疑具有十分重大的战略意义。为有效保护和利用深海海底资源,2016年我国颁布实施《中华人民共和国深海海底区域资源勘探开发法》,这是我国积极践行担保国义务的重要举措,为深海资源的合理调查开发提供法律基础。文章分析深海资源调查的必要性和我国深海资源调查的主要成果,梳理《中华人民共和国深海海底区域资源勘探开发法》等一系列涉及深海资源调查的法律规范,重点分析我国深海资源调查装备的发展,并对深海资源调查装备促进深海资源可持续利用进行展望。 相似文献

深海能力建设是海洋强国建设的重要组成部分,是国家有效利用深海、保障海洋权益综合国力的体现。广袤的深海区域赋存着人类社会可持续发展的战略资源,同时深海区域还是科学家开展宇宙起源、生命起源、气候变化等研究的天然实验室。文章从论述资源勘探开发和科学研究对国家深海活动能力的需求出发,分析了我国深海技术装备研发、应用现状和存在的问题,最后提出国家深海活动能力构成三要素:完善的深海技术装备体系、健全的深海装备应用平台、有效的深海装备应用体制和机制。 相似文献

A method for the estimation of the results of reconstruction of the trajectories of drifting buoys is proposed. It is based
on the comparison of the estimates of power spectral densities for the components of current velocity computed according to
three data sets: the data set of the coordinates of a drifting buoy with a built-in GPS receiver, the data set of coordinates formed on the basis of the first set but with data missing and observational errors
corresponding to the actual trajectory measurements by the Argos satellite location and data collection system by the Doppler method, and the data set of coordinates obtained as a result
of interpolation of the second set. As an example, we consider the procedure of realization of the proposed method and demonstrate
the efficiency of its application for the improvement of the reliability of reconstruction of the trajectories of drifting
buoys. 相似文献

An attempt has been made to estimate the fishery potentials of the EEZ of India on the basis of data on primary and secondary production. The total column primary production and zooplankton production have been calculated to be 265·9 and 9 million tonnes of carbon per year, respectively. From these values the fishery potential has been estimated as 2·5 million tonnes per year. To this, if we add the estimated demersal fish catch, being 1·2 million tonnes per year, the total potential yield comes to 3·7 million tonnes per year. Since the present average total catch is about 1·6 million tonnes in a year, the fish catch could be doubled. 相似文献

1992年,联合国21世纪议程提出了综合管理的概念,并认为它是海岸管理的最重要目标,而海岸管理的目的就是改进业已存在的管理实践的效率和效果。在21世纪议程的实施过程中,沿海国家面临着巨大的困难,即:为了使综合管理在实践中具有可操作性而建立适合的政府机构。韩国正是在国家范围和次一级区域进行这项工作的实验场所。这项工作的最重要成就是在1996年成立了具有综合协调各涉海部门职能的韩国海洋事务与渔业部(MOMAF)。这篇文章的内容主要来自于这些观察,即韩国政府为建立海岸带综合机制而进行了各种努力,特别是1992年联合国环发大会召开后到1997年初海洋事务与渔业部成立了海岸带管理处这段时间里开展的各种工作,文章重点在于评价在建立海岸带综合机制的过程中综合的概念是如何被应用并被挑战的。文章提出了在东亚地区沿海国家开展合作的可能区域的建议。 相似文献

天然气水合物地球化学特征 总被引:4,自引:0,他引:4
天然气水合物是在低温、高压以及有足够气体供应条件下形成的一种天然气(主要为甲烷)与水组成的似冰状固态化合物。天然气水合物中包含的甲烷碳是全球甲烷资源的重要组成部分,是一种数量巨大的潜在能源[1]。而且由于甲烷的温室效应,天然气水合物分解释放的甲烷进入大气中会严重 相似文献

We use many-year archival observations of hydrologic and hydrobiologic state of the Sea of Azov for the identification of
the structure of a model of its ecosystem. The ecosystem model, supplemented with expert estimates of bioresource consumption
(fish reserve), contamination level, and possible ecologic fines for violation of the sea natural state, is formalized by
the method of system dynamics. Hereat, the major part of influence functions is found in terms of observational data with
application of self-organization algorithms. We also present the results of simulated experiments with the model of the ecosystem,
which enable us to analyse scenarios of its behaviour under the influence of various external factors (wind, river discharge,
water exchange with the Black Sea, etc.).

Values of root mean square slope 0 and its variations -0 are estimated using the brightness field of an image of the surface of the sea near a speck of light. When 0 and -0 are defined it is highly important to take into account direct as well as dissipated solar radiation.The space-time analysis of the structure of the image brightness field is performed. This gives an opportunity to estimate dispersion relationship and the running effect of a brightness contrast packet. Comparison of the parameters obtained with the theoretical dispersion ratio of internal waves (IW) allows one to make a conclusion that IW surface manifestations are recorded in a frame.UDK 551.463.5 相似文献

We perform the numerical analysis of the long-wave response of the free surface of a fluid in a basin of variable depth to
the formation of an anomaly of the baric field for a finite period of time. In numerical experiments, we use the distribution
of depths typical of the south coast of the Crimea. We also study the dependence of the dynamics of the sea level in the zone
of the baric anomaly and in the shelf zone on the space and time scales of local changes in the field of atmospheric pressure
in the open part of the basin.
