近年来,随着国家资源管理体制改革的加快,海域资源市场化配置程度不断提高,海域招拍挂即将成为海域使用权出让的主要方式。对海域基准价格进行研究,可以科学确定海域使用权的价格,为海域资源市场化配置提供科学支撑。本文建立了海域定级和海域基准价格评估方法,并利用建立的方法评估了厦门市货运港口用海、客运港口用海、游乐场用海和游艇泊位用海的海域基准价格。结果显示,厦门市各级各类海域基准价格差异很大,各地区各类用海的海域基准价格在11.04~89.32万元/公顷之间。从区域看,同一区域不同用海类型的海域基准价格相差很大,厦门岛周边海域基准价格普遍较高,与陆域的经济发展水平相对一致;从用途看,同级别海域游艇泊位用海年均海域基准价格最高,货运港口用海最低。  相似文献

海域基准价格更新是海域市场发展的客观要求,可以为政府制定合理的海域政策提供重要依据。现有研究多集中于海域基准价格的制定,而较少涉及基准价格的动态更新。文章基于海域与土地资源的相似性,分析了海域基准价格动态更新的必要性和海域基准价格动态变化的主要原因,同时,对适用于海域基准价格动态更新的评估方法进行了深入探讨。  相似文献

随着国家全面推进海域资源市场化配置,海域招拍挂将成为海域使用权出让的重要形式,海域使用权价格评估是其基础性工作。文章设计建设填海造地用海一级市场海域使用权价格评估案例,利用不同评估方法对海域使用权价格进行评估,最后基于评估过程和结果对各评估方法的适用性进行分析。结果显示:假设开发法理论成熟,能很好地体现海域使用权价格的内涵,可作为海域使用权价格评估工作中最优选择的方法;成本法无法体现海域自然属性和其他影响因素对海域使用权价格的影响,且待评估海域往往为裸海,尚未有实际成本发生,因此并不适用于海域一级市场评估;成本法不适用的根源在于其忽略海域增值收益,亟须在原有计算公式的基础上增加海域增值收益。  相似文献

海域资源作为我国资源的重要组成部分,其科学的开发利用与合理计价对于我国经济发展有着至关重要的作用。自十八大提出"五位一体"和谐社会总构想以来,对于海域资源的价值又有了更深层次的理解,对其科学的计价方式也有了新的要求。海域基准价格作为海域使用与交易过程中的指导价格,在市场运行与开发过程中处于指导地位,科学地评估海域基准价格具有至关重要的意义。海域基准价格动态计量方法是考虑了时间因素、经济因素、社会因素等相关因素的价格计量方法,是一种较以往进步的、科学的计量方法。正确分析海域动态基准价格的界定与构成是正确计量海域动态基准价格的基础。  相似文献

通过开展海域资源现状调查,摸清海域资源禀赋基本情况,进行海域资源资产核算,建立实物账户和价值账户,是海域分等定级和价格评估的基础,是健全自然资源资产产权制度、保障海域使用金应收尽收、实现海域国有资源性资产保值增值、履行国家海域资源资产所有者职责的必要条件。文章针对我国现有海域资源调查核算不能满足海域有偿使用管理需要的具体问题,提出3点建议,包括:开展海域空间资源调查,建立资源实物账户;开展资源价值评估,建立海域资源价值账户;构建海域资源资产-价值核算体系。  相似文献

随着十八大提出的国家海洋战略与我国海洋经济的发展,海洋开发利用广度和深度不断拓展,市场机制在海域资源利用配置中基础性作用越来越重要。海域使用权以及宗海海域的出让、拍卖、转让、抵押、作价入股、海域资源回收及补偿等经济活动,都需要通过海域评估来确定合理的价格。成本法作为填海造地用海海域最常用的评估途径被海域评估人员广泛采用,成本法应用中必须考虑海域资源的自然差异因素与社会经济差异因素引起的海域增值收益对不同用海类型海域资产价值的影响。  相似文献

随着国家资源管理体制改革的加快,海域资源的市场化配置程度不断提高,而海域使用权价格评估是其基础工作。在诸多评估方法中,假设开发法把在开发和未开发海域假设为已完工状态而进行评估,非常适宜于当前海域市场化出让前的状态,已经成为目前海域使用权评估领域最常用的评估方法。文章选取A市游艇码头项目用海为例,利用假设开发法详细测算了该宗海域价格,并通过对测算过程和测算结果进行分析,探讨假设开发法在海域价格评估领域的应用及局限,对进一步完善海域使用权价格评估工作具有积极意义。  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.

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

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.).

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
