为增强对海上风电海缆路由廊道的认识以及促进海上风电项目集约节约用海,文章梳理广东省海上风电路由选划的基本情况,分析统一划定海上风电海缆路由廊道的困境及其原因。研究结果表明：虽然自然资源部门在审批过程中不断呼吁建立海缆路由廊道,并与企业和地方政府等利益相关者基于集约节约用海等原则选划部分海缆路由的登陆点,但海缆路由廊道仍面临选划工作严重滞后于产业发展、利益相关者复杂且众多以及技术工艺存在不确定性等难题,亟须加强与相关部门的协调,将路由廊道规划统一纳入国土空间规划体系,及时总结海上风电和海缆的相关技术并借鉴先进经验,科学合理地划定海上风电海缆路由,进而发挥路由廊道对海上风电产业发展的政策促进和引导作用。 相似文献

近年来我国沿海地区海上新能源用海、油气用海、交通运输用海等需求显著提高,对海洋空间资源的刚性需求急剧增加,供需矛盾日益紧张。尤其是海上风电用海,受国家宏观战略影响,呈现跨越式发展,装机容量跃居世界第一。大规模海上风电建设对海洋空间资源配置提出更高的要求,如何既保障海上风电用海需求,又协调海上风电与其他行业的用海矛盾,成为亟待解决的重要问题。树立自然资源集约利用理念能够良好解决上述问题,集约利用理念既是全面提高海洋空间资源利用效率的内在要求以及协调保护与利用显著矛盾的需要,更是协调保护与发展关系的关键。基于此,文章系统分析现有海上风电场外缘边线包络海域面积、确权海域面积等数据,采用集约化的空间资源开发理念,从项目选址与海缆路由、风电场设计与技术要求、用海范围及确权面积控制等方面完善海上风电用海面积控制指标体系,以期提高海上风电项目用海集约水平。 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

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

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 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
