《无居民海岛保护和利用规划》《无居民海岛开发利用具体方案》和《无居民海岛使用项目论证》是一套完整的用岛文件和申请材料,分别侧重于海岛定位和功能分区、开发项目空间布局、用岛合理性分析等内容。三者之间关系密切,《无居民海岛保护和利用规划》具有指导性、控制性和约束性特点,侧重于海岛定位和功能分区,是指导《无居民海岛开发利用具体方案》和《无居民海岛使用项目论证》的重要依据,由政府部门批准实施;《无居民海岛开发利用具体方案》要具体落实《无居民海岛保护和利用规划》提出的海岛保护与开发利用的一切要求,而《无居民海岛使用项目论证》依据《无居民海岛保护和利用规划》及其他法律法规及相关规划,对《无居民海岛开发利用具体方案》的用岛合理性进行论证,是支持海岛使用的科学分析材料。 相似文献

生境系统重要性和开发利用可行性是无居民海岛开发利用的重要依托。文章采用层次分析法与德尔菲法确定指标权重,针对研究区域特点,建立无居民海岛开发利用适宜性评价指标体系,在各因子分值量化处理后,定义相应指数,利用互斥矩阵定位无居民海岛开发适宜性类型分级。研究表明:长三角的生态屏障——九段沙岛,为低度适宜开发型海岛,无居民海岛开发利用适宜性评价指标体系适用于九段沙海岛。在开发利用方面,遵循可持续开展角度原则,九段沙应该保护和修复生境系统环境、从严把控开发强度、开展湿地保护。 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

We perform the numerical analysis of the long-wave response of the free surface of a fluid in a basin of variable depth to
the formation of an anomaly of the baric field for a finite period of time. In numerical experiments, we use the distribution
of depths typical of the south coast of the Crimea. We also study the dependence of the dynamics of the sea level in the zone
of the baric anomaly and in the shelf zone on the space and time scales of local changes in the field of atmospheric pressure
in the open part of the basin.
