海洋是高质量发展战略要地,推动海洋经济高质量发展是建设海洋强国的必然选择。文章从海洋经济高质量发展的内涵出发,以新发展理念为基础,运用熵权-TOPSIS模型评价沿海地区海洋经济发展质量的综合能力并分析其区域差异。实证结果显示:(1)五大准则层指标按权重从高到低排序依次为:海洋科技创新、对外开放、海洋经济结构、社会民生、海洋生态环境;(2)沿海地区的海洋经济高质量发展水平在考察期间为波动上升趋势,各省(自治区、直辖市)间海洋经济发展质量差距在逐渐变小;(3)影响海洋经济发展质量各子系统中,北部海洋经济圈在5个子系统评分中均处于较低水平。为此,提出促进海洋经济高质量发展的提升路径:海洋科技创新与海洋产业结构升级协同发展、完善海洋生态环境保护政策、打造对外开放新格局等。  相似文献

为促进我国海洋经济的高质量可持续发展,文章运用系统GMM实证检验海洋科技创新路径下环境规制对海洋经济发展的影响,并提出发展建议。研究结果表明:环境规制与海洋科技创新的联动显著促进海洋经济发展,且命令控制型环境规制的促进作用显著,而市场激励型环境规制的促进作用不显著;海洋劳动力投入对海洋经济发展起重要作用,对外开放程度对海洋经济发展的影响不显著;环境规制与海洋科技创新的联动显著促进东部和北部海洋经济圈的海洋经济发展且促进作用东部大于北部,但对南部海洋经济圈的促进作用不显著;未来应进一步完善环境规制政策、加快海洋科技创新、因地制宜发展、建设海洋人才队伍以及升级对外贸易结构。  相似文献

随着海洋强国战略的实施,探究海洋科技创新对于海洋经济的影响成为实现海洋强国目标的重要推动力。文章基于2008—2019年中国11个沿海地区的面板数据,构建面板模型,在金融发展视角下探讨海洋科技创新对于海洋经济高质量发展的调节效应以及门槛非线性作用。结果表明:海洋科技创新对于海洋经济高质量增长具有显著促进作用;在海洋科技创新对海洋经济高质量发展的影响过程中,金融发展规模和效率表现出正向调节效应,而金融发展结构的调节效应暂不显著;在海洋科技创新作用于海洋经济高质量发展的过程中,金融发展规模存在双门槛效应以及最佳金融发展水平区间,金融发展结构和效率均存在单门槛效应,即当金融发展结构大于单一门槛值时,海洋科技创新对海洋经济高质量增长表现显著正向作用,当金融发展效率大于单一门槛值时,海洋科技创新对海洋经济高质量增长的促进作用增大。  相似文献

The analysis of the structure of the cryolithozone, facies, and thicknesses of the Quaternary sediments and the results of the physicochemical mathematical modeling of the modern shelf of the western part of the Laptev Sea support the influence of the Late Pleistocene glaciations on the heat conditions and the distribution of the permafrost in the area. A ~200-m thick glacier formed under aerial conditions from atmospheric precipitation represented the metamorphosed snow cover. According to the modeling, the long-living (from 60?50 to 10?4 ky) glacier reduced the thickness of the permafrost rocks in the reviewed shelf area for 280–360 m. The Holocene marine transgression additionally decreased the thickness from 50–140 m on the inner shelf to 220–350 m on the outer shelf. The modern submarine cryolithozone 450-0 m thick is wide-spread in the studied region from the coast to the shelf boundary (isobaths of 130–140 m), where it pinches out at a distance of ~380 km from the coast at a depth of ~250 m above the sea level.  相似文献

We analyze the components of the carbon system of the Sevastopol bay waters and the balance of main sediment-forming substances using the data of field investigations in 1998–2008. The interannual variations of total inorganic carbon and the equilibrium partial pressure of carbon dioxide in the bay water are noted. An increase in the flux of carbon dioxide into the bay and in the content of organic carbon in bottom sediments is revealed, and an explanation of this phenomenon is given. The priority accumulation of organic carbon in the sediments of the bay is established. We assess the interannual variation in the relative abundances of organic and inorganic carbon as an index of the carbon cycle stability.  相似文献

We generalize and analyze the state of investigations of the influence of river waters on the hydrologic structure of the Black Sea. Specific features of the water, regime and hydrography of rivers flowing into the sea, data on the discharge of rivers, and intrayear and interyear variability of the discharge are presented. We discuss and analyze works studying the transformation of river waters, routes of desalinized sea waters, and their influence on the thermohaline structure and dynamic regime of the sea.

We analyze the results of numerical calculations performed according to the three-dimensional interdisciplinary model of an ecological system of the Black-Sea shelf zone near the estuary of the Danube. The complete system of equations of hydrothermodynamics is solved together with transport equations of the advection-diffusion-reaction type used to describe the transformation of a substance (nitrogen) between the components of the characteristic vectors of the ecosystem: plankton, detritus, and biogenic elements (nitrates). We describe the distinctive features of the circumcontinental distribution of components obtained as a result of numerical experiments and present arguments for the conclusion that the ecosystem of the Danube estuary water area plays the role of a buffer zone between the press of the Danubian biogenic pollutions and the neighbouring areas of the shelf zone and open sea.

Ten years of semistationary studies of the interaction of the ice cover and the coastal relief of the Kandalakhsa Gulf in the White Sea allowed us to reveal the peculiarities of these processes in the warm and cold years and the mechanisms of the origination of ice forms, including ice tents, which govern the character of the tidal flats. Three dynamic fast ice zones are distinguished by their geomorphological location, morphology, and ice dynamics. The dependence of the mechanisms and volumes of the enrichment of the fast ice in the sediments on the coastal zone??s relief was established. At the coast of the Kindo Peninsula (Velikaya Salma Strait), the ice mostly contains fine-sandy sediments. Coarser sediments, including boulders, are occasional and frozen into the ice at the contact of the fast ice and the bottom. At the expense of the ice??s spreading by 4?C6 times in the warm years and 2?C4 times in the cold years, several thousand tons of sediments mostly from the tidal flat??s surface (100?C700 m3 from 1 km of coast in the wide tidal flats and <50 m3 on the steep coasts) are delivered to the water area.  相似文献

A relationship between paths of the Kuroshio and Kuroshio Extension (KE) is investigated, using the satellite-derived altimetry dataset of 1993–2008. When the Kuroshio takes the nearshore nonlarge meander path or typical large meander path and resultantly goes through the deeper channel (about 2500 m) of the Izu-Ogasawara Ridge, the KE path adopts a relatively stable state with the two quasi-stationary meanders. On the other hand, when the Kuroshio takes the offshore nonlarge meander path and then passes over the shallower part of the Ridge (about 1000 m), the KE path tends to be convoluted, i.e., an unstable state.  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.).

The methodology and the first results of the computations of the volumes, masses, and growth rates of the sedimentary body of the buried Black Sea basin are presented. Their temporal evolution reflects the regional paleogeodynamics, in particular, the reorientation of the vector of the relative movement of the Arabian and Eurasian lithospheric plates and the related intensification of their collision in the late Miocene-Pliocene.  相似文献

The spatiotemporal variability of the hydrochemical composition of the riverine runoff in nearmouth areas is presented using the example of selected rivers of the Arctic Basin. The temporal dynamics of the riverine nutrient runoff are mainly determined by the seasonal and interseasonal variations in the drainage basins. The spatial variations in the chemical composition of riverine waters in the near-mouth areas are mainly caused by the dynamics of the water flow and the river bed relief and, to a lesser degree, by biochemical processes. It is shown that the variations in the nutrient composition of the waters in near-mouth areas are comparable in magnitude to those at the river-sea geochemical barriers.  相似文献
