随着海洋强国战略的全面实施,海洋生态文明建设作为生态文明建设的重要组成部分已经上升为国家战略,绿色发展强调转变传统海洋经济发展方式,注重海洋资源保护和生态环境修复治理,是实现经济、社会、资源、环境协调发展的新型发展模式。海洋环境监测是认知海洋环境现状、保障海洋生态文明建设和海洋经济绿色发展的重要技术手段。文章论述了海洋生态文明和绿色发展的内涵,给出了海洋生态文明示范区(试验区)和海洋生态红线区两大海洋生态文明建设载体,重点论述了当前以海洋水质浮标、海洋水文气象浮标、波浪浮标、潮位站(验潮井)、高频地波雷达、Argo浮标等为主的海洋环境在线监测和海洋遥感监测技术手段。从构建"岸-海-岛""天空-海面-海底""点-线-面-层"立体化、全方位、实时监测系统,推进在线监测关键技术攻关及配套服务建设等方面进行了展望。 相似文献

现代生态文明的系统研究始于西方工业化国家,是伴随着工业化的进程而展开。而我国的生态文明思想由来已久,早在5 000多年前就已形成了一套鲜为人知的人类生态理论体系。文章在回顾西方生态文明理念与中国生态文明思想的基础上,提出了海洋生态文明的内涵与本质。文章指出,海洋生态文明是以人与海洋的和谐共生为核心,以海洋资源综合开发与可持续利用为前提,以提升海洋对我国经济社会可持续发展的保障能力为主要目标,并进一步将海洋生态文明的内容归结为以下两点:1海洋生态系统的可持续发展,体现在海洋资源的可持续供给和海洋生态系统的良性循环;2人类社会的可持续发展,体现在社会经济的可持续发展和人的海洋生态文明意识的提高。海洋生态文明建设任务是以提高海洋生态文明意识为基础,以构建现代海洋产业体系为核心,以建设海洋生态安全屏障和有效控制入海污染物总量为保障,以海洋科技创新为依托,全面推进人与海洋的和谐共生、健康发展。在理论探讨的基础上,文章以厦门市为例介绍海洋生态文明示范区建设实践。 相似文献

为进一步提高我国海洋生态文明建设水平,促进海洋经济社会可持续发展,文章构建评价指标体系,基于BP神经网络模型,评价我国国家级海洋生态文明建设示范区的建设水平。研究结果表明:根据海洋生态文明建设研究框架以及定性指标和定量指标相结合等4项原则,从海洋经济运行、海洋资源禀赋、海洋生态环境、海洋管理制度和海洋文化科技5个层面,选取人均GDP等32项指标,构建示范区建设水平评价指标体系;利用BP神经网络强大的非线性映射能力、容错能力和联想记忆能力,对示范区建设水平进行评价,经模拟运算和检验,评价结果具有准确性和客观性;根据最终评价值,我国示范区建设总体处于中等水平,各示范区建设水平存在差异,其中青岛市等4地为高水平示范区,烟台市等4地为较高水平示范区,惠州市等7地为中等水平示范区,东台市等4地为较低水平示范区,盘锦市等2地为低水平示范区;各示范区应进一步加强优势和弥补不足,充分发挥引领作用,提高我国海洋生态文明建设整体水平。 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

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.).

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

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

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

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 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
