Integrated terrestrial and marine planning in England’s coastal inter-tidal zone: Assessing the operational effectiveness of the Coastal Concordat     

《Marine Policy》2016

In many countries, the regulation of activities and development in the marine environment has begun to evolve from a compartmentalised, fragmented, sectoral and uncoordinated system into a more strategic, comprehensive, integrated and transparent one. A remaining challenge, however, is the effective integration of marine and terrestrial planning, because the tools and mechanisms necessary for its achievement have been slow to be implemented. The introduction of the England's Coastal Concordat in 2013, as a voluntary framework for better integrating marine and terrestrial planning consents, represents an atypical mechanism to secure these goals. This paper is a preliminary survey of the perceived effectiveness of the Coastal Concordat, based on a survey of 32 professionals from the terrestrial planning authorities, marine statutory agencies and marine-sector businesses. While this evaluation is made less than two years after the introduction of the Coastal Concordat, it is important to undertake a preliminary examination, from various stakeholder perspectives, of the factors likely to be influential in the integration of regulatory systems, before the approach is ‘rolled out’ across other parts of England's inter-tidal coastal zone. The results indicate that the Coastal Concordat has produced benefits for marine planning in coastal areas, but that these improvements are largely experienced within the public sector in terms of better communication, early engagement, and a single point of contact. The marine sector businesses are more neutral about the benefits of the Concordat. It is clear, however, that marine sector businesses must participate in the formulation of any reforms if an effective integrated system of planning and management of coastal environments is to be achieved.  相似文献

选取三个黄淮气旋个例,分别以NCEP和T213客观分析场作为初始场,利用MM5模式对这些个例进行了模拟。将两种初始场模拟的黄淮气旋中心位置、中心强度和黄淮气旋前一时刻的实况位置作为输入,构建用于预测气旋中心位置和中心强度的人工智能神经元网络。发现:使用人工智能神经元网络可以较好地集成不同初始场下MM5模拟的黄淮气旋中心位置和强度,提高模式预报精度。  相似文献   

Between social and spatial convergence and divergence: an exploration into the political geography of European contact areas     

Milan Bufon 《GeoJournal》2006,66(4):341-352

The European continent, the motherland of nationalism, and the part of the world where political borders and different territorial and cultural identities are mostly interrelated, is now facing new challenges regarding how best to represent its numerous interests within one system. With the increase of international integration European countries began to devote greater attention to the development problems of their border areas that had to be helped to undertake certain functions in the international integration process. The fostering of a more balanced regional development also resulted in a strengthening of regional characteristics, which the new model could no longer ignore. Regional characteristics in turn have always been preserved in Europe by persistent historical and cultural elements of ethnic and linguistic variety. Therefore, it is not surprising that the process of European integration based on the new regional development model was accompanied by a parallel process of ethnic or regional awakening of minorities and other local communities. The key question for contemporary European (though of course this is not limited to Europe) political geography is, then, how the process summarised under the twin labels of social convergence and deterritorialisation will effect the persistent maintenance of regional identities and the corresponding divergence of regional spaces. Or, in other words: is the ‘unity in diversity’ European programme ever practicable and exportable on a world-wide scale or are we to be absorbed by a new global ‘melting pot’?  相似文献

布尔莎模型在GPS时间序列融合中的应用     

王紫燕 《中国地震研究》2014,28(1):46-53

In this paper the method of combining the Bursa model to integrate several regional time series to derive a unified global time series is introduced in detail. Then, an example taken from CMONOC （ Crustal Movement Observation Network of China） is used to test if the combination method is feasible. The precision of the integrated time series with the combination method is below 2mm （North） , 3mm （East） , that is same as the results from the direct integration of the time series and the precision of the baseline is below 6mm, which proves that the combination method can be used to integrate several regional time series to derive a unified global time series.  相似文献   

井中震源的远场波场特征研究          下载免费PDF全文

井中震源在逆VSP、随钻地震和采矿地球物理研究中都有广泛应用.满足"小井孔"(井孔半径远小于特征波长)及"远场"(炮检距大于特征波长)假设时,井中震源的远场波场存在解析解.为了检验解析解在不同情况下的适用性,本文使用最速下降积分计算了不满足上述假设时井中震源远场波场的合成地震记录,即半解析解.模型试验表明,解析解只能在同时满足"小井孔"和"远场"假设时使用;当这两个假设条件不满足时,解析解的振幅和波形相对于半解析解会有明显的偏差.随着假设不满足程度的增加,偏差会逐渐增加,并会逐渐影响走时的准确拾取;这种条件下,采用半解析解才能获得准确的井中震源波场.  相似文献
