海洋空间规划是协调用海活动和保护生态环境的海洋综合治理机制,也是提升海洋资源可持续利用和发展蓝色经济的有效工具。《柬埔寨海洋空间规划(2018-2023年)》运用实地调查、综合评价、GIS空间数据分析和专家咨询等技术方法,构建了柬埔寨海洋功能区分类体系,划分了9类33个功能区,制定了功能区管理要求、行动计划和用途管控清单,提出了"发展目标+功能分区+用途管控+实施引导+决策系统"的空间规划编制和实施模式。  相似文献

Since 2009, there has been a shift in UK marine governance with the Marine and Coastal Access Act in which a core mechanism is marine planning, designed to replace a fragmented, ad hoc, and bureaucratic process of marine management with a strategic, integrated, and centralised system. This shift has been justified by the UK government as a more efficient procedure for delivering sustainable development (SD), which is the overarching objective of UK environmental policy. This article, which is based on data from key informant interviews and secondary sources, analyses the shift to understand its aspirations and the challenges facing it. The issues focused on include its holistic approach; its centralising tendencies; its streamlining processes; and its implicit commitment to renewable energy. In these four issues there are tensions between aspirations and challenges, and the conclusion is that the success of the new mode of marine governance depends on satisfactorily resolving these tensions.  相似文献

基于地震动参数的建筑物震害研究   总被引:15,自引:3,他引:12  
本文介绍了多步简化的push—over(MSP)方法,引导出求解单体建筑物易损性指数和群体建筑物易损性指数的办法,并通过建筑物平均易损性指数曲线,来评价城市的总体抗震性能。本文不采用过去以烈度为地震输入的易损性评定方法,采用地震动参数作为城市建筑物易损性的评定标准。给出的易损性指数曲线,可用来查找不同地震动参数下各类建筑物的易损性结果,比较城市各类建筑物的抗震性能。本文研究可望在城市建筑物震害评估中有好的应用前景。  相似文献

As increasingly large extents of the global oceans are being managed through spatial measures, it is important to identify area characteristics underlying network distributions. Studies discerning spatial patterns in marine management have disproportionately focused on global networks. This paper instead considers the single country context of Japan to illuminate within-country drivers of area-based conservation and fishery management. A dataset containing potentially relevant socioeconomic, environmental, and fisheries factors was assembled and used to model prefecture-level counts of marine protected areas (MPAs) and territorial use rights for fisheries (TURFs) throughout Japan's waters. Several factors were found to significantly influence the number of TURFs in a particular area, whereas MPA patterns of use remain largely unexplained. TURFs are frequently noted as more suitable for managing fisheries of low mobility species and our analysis finds greater use of TURFs in areas that rely heavily on benthic catch. The number of trading ports was also found to be positively related to TURF distributions, suggesting economic infrastructure may influence the use of this fisheries management tool. In-line with global analyses, MPA patterns of use were not found to be significantly related to any of the potential explanatory variables after correcting for the number of statistical comparisons that were carried out. Differences in our ability to model the use of TURFs and MPAs may arise due to the narrower objectives associated with the former (e.g., income, employment) in comparison to the often broad and varied goals that motivate use of the latter.  相似文献
