改革开放以来,开放型经济是我国各地区发展的重要方向。党的十八大也明确提出"建设海洋强国"以及"全面提升开放型经济水平"的发展战略。由于受地缘条件、政策倾斜、跨国公司产业配置、国际分工以及人流、物流、信息流等要素的全球流动等因素的影响,我国各地区开放型经济水平存在巨大差异,辽宁沿海经济带的内部差异也十分显著。在国内外研究的基础上,基于2001—2011年的相关数据,利用外贸依存度(出口依存度和进口依存度)、外资依存度、旅游开放度和综合开放度等指标来综合测度辽宁沿海经济带及其各城市的经济开放度水平。入世以来,辽宁沿海经济带的开放型经济水平得到不断深化,但总体水平偏低且开放型经济结构不合理;大连市的综合开放度在各时期都远远领先于带内其他城市,各城市间的开放度差异较大。最后,根据辽宁沿海经济带开放型经济发展的现状提出了针对性建议。 相似文献

在衡量某个地区的经济发展状况时,人们更多考虑的是该地区的区域经济发展差距状况。由于自然、地理以及历史等方面的原因,辽宁沿海经济带海洋经济发展程度不甚平衡,沿海各市海洋经济发展还存在着很大的差距。文章借助基尼系数分析法的产业结构和产业效应分解,对辽宁省沿海6市的海洋经济发展、海洋产业构成及区域发展差距进行了分析,揭示了海洋产业发展差距对辽宁海洋经济增长的影响。通过分析,为辽宁沿海经济带海洋产业区域一体化.发展提供了一守的科学依榧 相似文献

为推动我国振兴东北老工业基地战略,充分发挥我国东北地区面向海洋的区位优势,加快区域经济的发展和繁荣,文章从基础条件、空间布局和实施重点3个方面,分析我国东北地区海洋经济的区域协同发展战略。研究结果表明:辽宁省是海洋经济大省,而在打破传统"沿海"观念的基础上发展吉林省和黑龙江省的毗海经济和向海经济,有利于辽宁省海洋产业的转型升级和整个东北地区海洋经济的区域协同发展,俄罗斯远东发展战略与我国振兴东北老工业基地战略也为此创造了环境和机遇;我国东北地区海洋经济区域协同发展的空间布局为"一轴一带两区",其中"一轴"为大连至佳木斯的铁路通道,"一带"和"两区"分别为辽宁沿海经济带、延边州海洋经济区和绥芬河海洋经济区,各地发挥各自的区位和产业优势,科学布局海洋产业,形成集聚、辐射和带动力量;我国东北地区应大力推动海洋经济一体化、资源配置市场化、对外开放国际化和科学技术创新化,从而实现海洋经济的区域协同发展。 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

The methods of perturbation theory and integral representations are used to analyze the general properties of a system of
equations of the mechanics of inhomogeneous fluids including the equations of momentum, mass, and temperature transfer. We
also consider various submodels of this system, including the reduced systems in which some kinetic coefficients are equal
to zero and degenerate systems in which the variations of density or some other variables are neglected. We analyze both regularly
perturbed and singularly perturbed solutions of the system. In the case of reduction or degeneration of solutions, the order
of the system decreases. In this case, regularly perturbed solutions are preserved (with certain modifications) but the number
of singularly perturbed components participating in the formation of the boundary layers on contact surfaces and their analogs
in the bulk of the fluid, i.e., the elongated high-gradient interlayers, decreases. The interaction between all components
of the currents is nonlinear, despite the fact that their characteristic scales are different. 相似文献
