在全面推进生态文明建设和打造"美丽海洋"的愿景下,融入生态建设理念是区域建设用海规划制度成功的关键。文章从理念试用期、快速发展期和审视思考期3个阶段回顾我国区域建设用海规划制度的沿革,提出制度实施过程中存在的重经济效益而轻生态建设、节能减排措施不到位、缺少海洋和陆地生态系统的有机联系以及占用自然岸线和破坏滩涂生境等问题;从新形势下贯彻落实生态建设理念的战略需求出发,结合生态建设理念在不同功能区域建设用海规划中的实践,提出低冲击发展、融入更多的生态要素以及注重节能减排和低碳发展等建议,为区域建设用海规划制度和海洋管理工作的完善提供科学借鉴。  相似文献

党的十八大明确了推进生态文明建设、建设海洋强国的战略部署,对现阶段海域管理工作提出了新要求。海域使用论证作为海域管理的重要技术支撑,是贯彻落实生态文明建设,合理配置海域资源,实现科学用海、科学管海的重要抓手。海洋生态调查是海域使用论证的重要环节,高质量的海洋生态环境资料提升海域使用论证的科学性和权威性。新形势下,海洋生态调查也面临着新挑战,文章在分析海洋生态调查在海域使用论证中的地位和作用的基础上,结合新职责和新政策,提出今后海域使用论证中海洋生态调查的优化调整思路,即紧跟职责要求、聚焦生态系统调查、强化岸线资源调查、服务生态保护修复。  相似文献

与单个项目相比,区域建设用海规划面积大,且规划区内的项目存在一定的不确定性,用海面积合理性分析的难度较大。根据区域用海规划建设规模和设计标准,结合区域建设用海规划区的功能定位,分析区域建设用海的实际需求,从海域资源的节约、集约利用角度,进行用海面积的合理性分析,是区域建设用海规划海域使用论证的关键之一。文章以福建省南安区域建设用海规划为例,从海域资源的节约、集约利用角度,进行用海面积的合理性初步探讨。  相似文献

面对当前海洋经济发展和海洋开发的热潮,国家海洋局提出开发利用海洋资源必须坚持“五个用海”的原则。区域建设用海,作为大规模、集中、连片式的开发海洋资源,更应切实贯彻落实“五个用海”的理念。文章以《晋江市围头湾区域建设用海规划》为例,通过区域经济发展的现状,界定用海需求,科学确定用海范围、面积、功能和分区,分别探讨了规划用海、集约用海、生态用海、科技用海和依法用海在区域建设用海中的应用。  相似文献

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

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.

为研究黄河入海径流变化条件下河口附近海域盐度扩散特征,以更好地保护河口海域生物资源多样性,本文以黄河下游利津水文站的长序列实测径流数据资料为基础,利用近海水动力模型FVCOM,分析径流变化对黄河口海域盐度的影响规律。结果表明:黄河口与莱州湾之间存在顺时针的环流系统,在余流作用以及涨落潮方向的影响下,黄河冲淡水长期向莱州湾扩散;丰水期黄河冲淡水几乎影响了整个莱州湾,27盐度锋可以到达莱州湾中部,27等盐线的表层包络面积为2 665.61 km2,占莱州湾的1/4左右,枯水期低盐度水只有向南扩散的趋势,27以下的低盐度水集中分布在黄河口门附近,27等盐线的表层包络面积只有199.65 km2;5月份,随着入海径流量增加,27等盐线扩散的范围、距离、方向都会发生明显变化。在对近海生物资源有迫切保护需求的情景下,适当减少其他用水户供水量以增加入海生态径流量,可以有效改善黄河口海域附近的盐度情况,为生物资源的生长繁殖创造良好条件。  相似文献

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

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.

The authors have previously determined that the effectiveness and failure pattern of the ice cover caused by flexural-gravity waves generated by a submerged body motion near the bottom ice can greatly depend on the depth of the water area. In its turn, the presence of a ledge on the ice surface may affect a wave propagation pattern. This paper presents an experimental study of the bottom contour influence on the deflection and length of flexural-gravity waves. The authors describe a numerical model for the analysis of the deformed state of ice caused by hydrodynamic loads due to a submarine motion, taking into account the bottom contour. The experiments are carried out in the ice tank. The results of calculations and experiments are compared.  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.).
