根据国家推行海域有偿使用制度的历程及历年海域使用管理数据,从海域有偿出让方式、海域有偿出让配套措施、海域使用金征收等方面总结了中国海域有偿使用制度实施现状。结果表明:目前,中国海域有偿出让以行政审批为主,同时,市场化方式出让工作稳步推进,沿海各地纷纷开展海域使用权招标拍卖挂牌出让工作。国家海域使用金征收逐步规范,执行2007年新海域使用金标准后,全国海域使用金征收总额大幅增加,以招拍挂方式出让海域征收的海域使用金也逐年递增。不过,填海造地用海海域使用金标准远低于毗邻土地价格,无法有效调控填海造地规模。针对海域有偿使用制度实施现状,提出了几点建议,认为海域使用金标准需要进一步细化,海域市场化出让要和严格的海域用途管制相结合,填海造地项目应该与毗邻土地捆绑出让,海域市场化出让方式暂时以招标和挂牌为主。  相似文献

本文构建了海域资源资产价值核算的理论与方法,采用市场法和收益法测算未取得使用权海域资源资产的预期纯收益,综合核算海域资源资产价值。结果表明,我国海域资源资产价值总量高,主要集中在未取得使用权海域;不同区片未取 得使用权海域的资产价格与功能类型、离岸距离和用海结构有关。通过市场法和收益法核算出的海域资源资产价格相近, 其中收益法核算的未取得使用权海域资源资产的价格较高,与我国海域资源资产市场化程度不高、近年来海域使用金征收标准 调整有关。开展海域资源资产的分类核算能够在我国现有的海域定价基础上,科学合理地评估海域资源资产的预期收益,核算未取得使用权的海域资源资产价值。应根据自然条件和规划用途开展海域资源资产的精细化管理,科学合理地定价, 并完 善资产的有偿使用和用途管制措施, 从而确保国有自然资源资产保值增值,促进海洋经济持续高效发展。  相似文献

一、海域使用金各级财政分成比例海域使用金是国家凭借海域所有权依法向海域使用权人征收的一定年限的海域使用权出让金。海域有偿使用制度的核心就是海域使用金的征收管理。近年来,随着全国各地海域使用管理工作力度的不断加大,全国沿海各省、直辖市、自治区在全面推行海域审批确权制度的同时,相继建立了海域有偿使用制度,明确规定了海域使用金的征管方式、征收标准、分成比例、资金用途和减免政策等内容。几年来的海域使用管理实践证明,海域使用管理是一项政策性强、涉及面广、管理对象多、技术性强、管理成本高的工作。海域使用金作…  相似文献

海域使用权和土地使用权均为我国主权领域内的不动产权.海域使用论证是海域使用权审批的重要依据.海域使用论证与土地利用审批依据的主要相同点是两者均实行用途管制,以规划(区划)为评估依据;均需要勘测定界.但两者在工程描述、工程引发的环境变化及防治对策分析、利益相关者分析等主要内容方面存在较大的差异.造成上述状况的原因是海域和土地在本质上既有一定的共性(两者均为实现其他开发方式的载体、位置固定性、数量的不增性、利用方向及附属生态逆变的困难性),也有明显的差异(海域的开放性和流动性).  相似文献

我国有着辽阔的海域及其资源与环境,为合理、有效地开发利用海域,我国建立了海域使用权制度,并通过征收海域使用金的方式对海域资源进行管理。文章分析了海域使用金征收的理论依据,论证了我国的海洋资源、海域利用方式及海域资源的特点,并以此作为海域使用金的征收依据。从海域资源是自然资源的一种这一角度出发,建立了机会成本法、海域资源破坏损失估算法、市场价值法、恢复费用估算法和影子工程法五种评估方法,为基于行政管理配置和市场配置的海域管理体制提供了计算依据。  相似文献

Preformed Cd and PO4 were investigated in the northwestern Pacific (Station CM05) and the Okhotsk Sea (Station CM06), and the relationship between the two elements was examined. At CM05, from the apparent oxygen utilization (AOU)–Cd and PO4 plot, the different molecular ratios of consumed O2 to regenerated Cd and PO4 were calculated to be 254,000 (Cd) and 96 (PO4) for the shallow layer (30–99 m) and 613,000 (Cd) and 170 (PO4) for the deep layer (below the oxygen minimum layer), which suggested the preferential remineralization of Cd and PO4 in the shallow layer. At CM06, regeneration ratios of O2/Cd, PO4 were obtained only in the shallow layer (29–124 m) as 227,000 (Cd) and 75 (PO4). The calculated preformed Cd and PO4 concentrations in the shallow layer were 0.59 nM of Cd and 1.6 μM of PO4 at CM05 and 0.35 nM of Cd and 0.95 μM of PO4 at CM06. These concentrations were much higher than those (close to 0) in the low-latitude area, which was attributable to the supply of these constituents from deep water by the strong winter convection. In the deep layer, at CM05, preformed concentrations were 0.64 nM of Cd and 1.4 μM of PO4. Preformed PO4 generally agreed with previously reported values in the Pacific, which suggested that the concentrations of the initial PO4 in the deep water were preserved as preformed through the movement to the northwestern Pacific. On the other hand, obtained preformed Cd in the northwestern Pacific deep water showed a somewhat higher value than that in the southwest Pacific. The possibility of the terrestrial input and remineralization of Cd by CaCO3 dissolution during the northward movement was considered. A plot of Cd and PO4 showed a linear relationship with slopes of 0.34 and 0.40 (nM/μM) at CM05 and CM06, respectively, which generally agreed with the reported values in the North Pacific.  相似文献

渤海、黄海、东海冬季海流场温度场数值模拟和同化技术   总被引:6,自引:0,他引:6  
利用NASA高分辨率的卫星遥感资料SST,采用Nudging同化来模拟渤海、黄海、东海的三维温度场,减小用热通量作上边界条件所带来的误差.结果表明,模拟的海流场能较好地反映渤海、黄海、东海的环流特征.数据同化后的温度场优于未经同化的温度场.3个选择站点的同化值与实测值的均方根误差分别为1.307,0.526,0.744,用热通量资料模拟的水温与实测值的均方根误差分别为2.160,0.979,1.330.尽管只同化了海表温度,但数据同化对三维温度场结构都有影响.  相似文献

采用东海黑潮主流段长时间序列的实测温盐资料,研究了东海黑潮上层温度、上层盐度的变化及其与中国东部降水和地面气温的关系.结果表明,在过去50 a内,东海黑潮上层海温呈上升趋势,而上层盐度略呈下降趋势.东海黑潮上层海温和我国东部地面气温的关系在冬季十分密切,呈现出大面积显著的正相关,这与冬季南下冷空气的整体降温作用有关.夏季,长江中下游江水的增多致使大量长江冲淡水入海,可能是导致黑潮上层水盐度下降的一个原因,此时东海黑潮上层盐度与我国大陆东部降水呈负相关.  相似文献

This is a historical review of Canadian policy at the Third UN Conference on the Law of the Sea. Canadian objectives with regard to the territorial sea, fisheries, pollution prevention and the continental shelf are outlined and the role played by the Canadian delegation at UNCLOS is described. The article then examines the impact of the Convention on Canada, particular attention being paid to the Canadian Exclusive Economic Zone and the Canadian role in the controversy over seabed mining. The author concludes by arguing that Canada was a major beneficiary of the Convention, but that US opposition has placed the future of the Convention in jeopardy.  相似文献

Micronuclei (MN), nuclear buds (NB) and fragmented-apoptotic cells (FA) were analyzed in mature peripheral blood and immature cephalic kidney erythrocytes of flounder (Platichthys flesus), dab (Limanda limanda) and cod (Gadus morhua) from 12 offshore sites in the Baltic Sea (479 specimens) and 11 sites in the North Sea (291 specimens), which were collected during three research vessel cruises in December 2002, 2003 and in September 2004. The highest levels of environmental genotoxicity (frequencies of MN up to 0.5‰, NB – up to 0.75‰) and cytotoxicity (FA – up to 0.53‰) were observed in flatfishes from areas close to oil and gas platforms in the North Sea and in zones related to the extensive shipping and potentially influenced by contamination from large European Rivers (Elbe, Vistula, Oder). In dab from the offshore zones of the North Sea, the levels of nuclear abnormalities were higher as compared to those in dab from the Baltic Sea. Responses in immature kidney erythrocytes were higher than in mature erythrocytes from peripheral blood. MN frequency lower than 0.05‰ (the Baltic Sea) and lower than 0.1‰ (the North Sea) could be suspected as a reference level in the peripheral blood erythrocytes of flatfish.  相似文献

The purpose of our work was to obtain the most possible detailed information about the composition, concentration, and structural features of the magnetic minerals contained in the rock to reveal the differences in the magnetic properties of the peridotites under various circumstances of the mantle magmatism and different conditions of metamorphism. To do this, we examined and analyzed the magnetic and petrographic characteristics of four collections of oceanic and alpinotype spinel peridotites. The main object for comparing the magnetic characteristics was the Gorringe ridge, which lies in the eastern part of the Atlantic Ocean. The peridotite samples from the Gorringe ridge differ from the other collections in many magnetic parameters: I n , χ, Q, I rs /I s , H c , H cr , and H m . The principal question of our work was to clarify the nature of the Earth’s crust where the Gorringe ridge formed. This subject was studied many times in the literature, but the researchers did not reach a common opinion. In accordance with our data, the spinel peridotites from the Gorringe ridge represent a subcontinental lithosphere mantle of the Iberian continental margin. During the metamorphism, the formation of magnetite occurred in the peridotites of the Gorringe ridge in several stages and had a regressive character. Our investigations explain the results of the analysis of the anomalous magnetic field over the Gorringe ridge, which is characterized by sharp roughness and high intensity of the local signchanging anomalies.  相似文献

A conclusion about two extreme regimes existing in the large-scale circulation in the North Atlantic has been drawn based on an analysis of the inter-annual variability of the analogue to the Rossby index, as well as that of the heat and dynamic characteristics in separate areas of the north subtropical circulation. The former is defined by a high level of circulation both in the atmosphere and in the subtropical water circulation. In the current century this regime was realized mainly in the years pertaining to the middle and end of a 22-year solar activity cycle (a 22-year cycle). The relatively low level of atmospheric circulation and the slackened water mass transport are typical of the second regime. It dominated mainly during the years relevant to the beginning and second half of a 22-year solar activity cycle.Translated by Mikhail M. Trufanov.  相似文献

The upper Oyashio intermediate water, one of the source waters for the Sea of Okhotsk intermediate water, is exhibiting a warming trend. The historical data show that the upper Oyashio temperature increased by 2.4°C during 1953 to 2007 at the potential density of 26.75 at depths of approximately 170 m. This rate of warming is much faster than that of the global ocean and the Sea of Okhotsk. The upper Oyashio warming is likely linked to the penetration of warm water of the Alaskan Stream westward. One mechanism of this warm Alaskan Stream water penetration is associated with large Aleutian eddies.  相似文献
