为促进我国沿海地区海洋经济社会和海洋生态环境协调可持续发展,文章采用成熟的海洋经济社会系统评价指标体系,综合运用环境库兹涅茨曲线、耦合协调度模型和逐步回归法,测算2006-2016年我国沿海地区海洋经济社会发展指数,分析海洋经济社会系统与近海水质间的拟合关系、弹性、耦合度和耦合协调度,并从系统、状态和指标3个层面解析影响近海水质的海洋经济社会因素。研究结果表明:2013年以前海洋经济社会发展与近海水质基本呈反向变化关系;近海水质的海洋经济社会系统弹性自2014年开始转为正值,但二者的耦合度和耦合协调度均较低;海洋社会发展对近海水质存在明显负向影响,海洋第三产业发展、海洋科技成果转化和海洋自然保护区建设有利于近海水质改善。建议严控陆源排污入海,提高海洋科技成果转化效率,优化海洋产业结构,持续加强海洋自然保护区建设,提升近海水质。 相似文献

赵晓龙 《海洋与海岸带开发》2014,(5):17-20
自然保护区作为当前生物多样性就地保护的最主要场所,对维护生物多样性以及实现广泛的社会目标具有重要作用,其发展动态和分布特征是保护区现状分析的重要内容之一。通过对我国国家级自然保护区调整的发展历史特征、空间特征、类型特征和管理特征等方面的动态特征进行探讨分析,为我国自然保护区管理政策研究提供参考依据。 相似文献

文章以中美两国海洋自然保护区为研究对象。首先对比了中美两国对海洋保护区的定义,为全文定下理论基础。随后采用层次分析法就海洋自然保护区的划分、类型、管理体制、管理经费,进行进一步的对比。从而引起对中国海洋自然保护区的建设管理进行讨论,找出中美两国海洋保护区的差距。文章认为,海洋自然保护区可持续发展应协调好生态、经济和社会三大效益。首先,科学论证和合理规划是我国海洋自然保护区可持续发展的基础和关键。其次要改善管理机制,保证管理资金的充足,并加强海洋自然保护区的科学研究工作,大力开展生态旅游,努力协调环境保护和社会发展之间的关系。 相似文献

营口市位于辽宁省的中南部,面对渤海的辽东湾,背依鞍山市平原丘陵,东邻辽东崇山峻岭,西接盘锦市沿海平原,有辽河蜿蜒人海,海岸线绵延曲折。由于受海洋、河流的影响.营口市四季分明,气候宜人,蕴藏着丰富的滨海旅游资源,海蚀景观、地质珍迹、人文景观等资源各显异彩;尤其是海水浴场,条件极为优越,与国际上一流的海水浴场相比.毫不逊色,在某些特征上还稍胜一筹。 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
