您知道什么是大陆架吗? 沿海国的大陆架包括其领海以外依其陆地领土的全部自然延伸,扩展到大陆边外缘的海底区域的海床和底土,如果从测算领海宽度的基线量起到大陆边的外缘的距离不到200海里,则扩展到200海里的距离。  相似文献

我国的《领海及毗连区法》第2条规定:"领海基线向陆地一侧的水域为中华人民共和国的内水"。我国的《海域使用管理法》第2条规定:"本法所称内水,是指中华人民共和国领海基线向陆地一侧至海岸线的海域"。"两法"对"内水"的定义有水域和海域之分,因此容易引起解读上的分歧或执法上的模糊。分歧之一是,根据《海域使用管理法》,从领海基线向陆地一侧至海岸线部分,是否包括河口、海湾、滩涂等"内水";分歧之二是,根据《领海及毗连区法》,是否认定一部分"内水"即内海是由直线基线法所致。为什么"两法"对"内水"有水域和海域两种不同的定义?其一,"两法"针对的客体不同,《领海及毗连区法》针对的客体是国际或国外,该法的主体是国家主权;《海域使用管理法》针对的客体是国内海域,该法的主体是国内海域的使用管理。《联合国海洋法公约》(以下称《公约》)规定"领海基线向陆一面的水域构成国家‘内水’的一部分",那么另一部分"内水"就是正常基线向陆一侧的水域,包括江、河、海湾等,它完全置于国家领土主权之下。其二,用专业术语上的海岸线替代《海域使用管理法》中的海岸线会出现矛盾。专业术语上同指水陆分界线的有海岸线和"干出线"两种。前者是涨潮时离岸最近的线,后者是退潮时离岸最远的线,依据《公约》规定:"测算领海宽度的正常基线是沿海国官方承认的大比例尺海图所标明的沿岸低潮线,即退潮时海水离岸最远的那条线",所以低潮线更加符合《公约》和《海域使用管理法》中海岸线的定义,怎样理解海岸线才不会出现矛盾呢?本文认为,完全意义上的海岸线是大潮高潮线与低潮线之间的一条带状面,这个面有时被水淹没,有时出露,且宽窄不等,陡缓不一。当解读了《公约》的有关条款后,就不难理解领海基线向陆地一侧至海岸线的水域中有盐度为0.05~30和30~36范围的"内水"存在,盐度范围为0.05~30的"内水"是指按正常基线法划定领海基线而出现的"内水",包括水域和海域;盐度范围为30~36的"内水"是指按正常基线与按直线基线法划定的领海基线之间出现的"内水",即内海。它们在法律层面上有主从之分,不能混淆。  相似文献

随着各国海岸附近海港工程逐渐增多,部分国家存在将领海基线向海一侧调整的倾向,进而对领海、专属经济区等海域的划定产生重要影响。选取24处典型海港工程样点进行研究。结果表明,24处样点中,5处会造成各划界海域面积显著扩大。多数情况下,领海、毗连区和专属经济区面积依次扩大。模拟实验表明,划界海域面积变化量与海港工程的形态、位置及其周边关系等多个因素有关。  相似文献

由于领海基线一般由折线组成且地球表面为球面,基于领海基线外推领海、毗连区和专属经济区的实际计算存在困难。文章基于交圆法设计最短距离法和椭圆法2种算法并对其优劣性进行比较,研究表明:外推12nmile领海和24nmile毗连区的界线基本与外推的领海基线平行,外推200nmile专属经济区的界线形状变化较大;最短距离法精度高但计算量较大,椭圆法所需计算时间短但精度较低且没有消除误差。  相似文献

2012年9月10日,日本政府不顾中方一再严正交涉,宣布"购买"钓鱼岛及其附属的南小岛和北小岛,实施所谓"国有化"。这是对中国领土主权的严重侵犯,是对13亿中国人民感情的严重伤害,是对历史事实和国际法理的严重践踏。中国政府和人民对此表示坚决反对和强烈抗议。  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.

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.

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

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

The methodology and the first results of the computations of the volumes, masses, and growth rates of the sedimentary body of the buried Black Sea basin are presented. Their temporal evolution reflects the regional paleogeodynamics, in particular, the reorientation of the vector of the relative movement of the Arabian and Eurasian lithospheric plates and the related intensification of their collision in the late Miocene-Pliocene.  相似文献

The spatiotemporal variability of the hydrochemical composition of the riverine runoff in nearmouth areas is presented using the example of selected rivers of the Arctic Basin. The temporal dynamics of the riverine nutrient runoff are mainly determined by the seasonal and interseasonal variations in the drainage basins. The spatial variations in the chemical composition of riverine waters in the near-mouth areas are mainly caused by the dynamics of the water flow and the river bed relief and, to a lesser degree, by biochemical processes. It is shown that the variations in the nutrient composition of the waters in near-mouth areas are comparable in magnitude to those at the river-sea geochemical barriers.  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.).
