随着沿海地区经济的快速发展,海岸带空间资源的利用将呈现多样化的特征。海岸带空间功能分区可以优化海岸带空间资源配置,统筹协调海岸带空间开发与保护格局,是海岸带资源可持续利用的重要基础。文章针对海岸带空间的特殊性,构建指标体系,对海口海岸带进行模糊综合评价,探讨海口海岸带空间适宜功能类型,并基于GIS 技术进行功能分区。结果表明：海口海岸带主要功能空间类型为旅游娱乐空间、城镇建设空间、农林渔牧空间和生态保护空间,其面积占比分别为16.84%、21.18%、22.54%、35.77%。其中生态保护空间面积最大,主要分布在海口市东部片区的东寨港。 相似文献

从快速城镇化背景下土地利用变化的角度来分析浙江省海岸带生态系统服务价值(ESV)损益情况,将ESV的估算引入海岸带开发决策,对浙江省海岸带资源的可持续利用具有重要意义.以1990、2000、2010年遥感解译数据为基础,研究了快速城镇化背景下浙江省海岸带土地利用类型变化,并通过构建ESV估算模型,估算了1990~2010年间浙江省海岸带ESV变化.结果表明:1990~2010年间,由于城镇化速度不断加快,浙江省海岸带土地利用类型变化显著,主要表现为城镇建设用地大量增加,林地和耕地面积减少.期间浙江省海岸带ESV总量不断减少,从352.78亿元降至299.64亿元,降幅达15.06%.浙江省海岸带ESV空间分布不断由高价值区域向低价值区域转变.各土地利用类型价值系数(CS)均小于1,价值总量对价值系数弹性不大,所设置的ESV系数原始值较为合适.浙江省海岸带土地利用强度不断上升,其空间分布与ESV变化率空间分布具有一致性,无序增加的城镇建设用地占用林地和耕地而引起的土地利用结构转变是海岸带ESV不断减损的主要原因. 相似文献

为促进粤东地区发挥区域优势、提升海岸带生态功能和促进可持续发展,文章概述粤东海岸带生态系统的类型及其分布,分析其面临的问题,并结合已开展的海岸带生态保护修复项目提出建议。研究结果表明：粤东具有砂质海岸生态系统、重要河口生态系统、红树林生态系统、珊瑚礁生态系统和海湾生态系统等海岸带生态系统,海洋资源十分丰富;但面临海岸侵蚀、环境污染和过度开发利用等问题,不利于发挥海岸带生态和减灾功能;在已开展的中央海域使用金支持项目、“蓝色海湾”整治行动、围填海项目生态保护修复和海岸带保护修复工程等的基础上,未来应开展海岸带生态系统现状调查和评估、加强滨海湿地保护、建立海岸带生态系统动态监视监测平台以及加快海岸带生态保护修复标准体系建设。 相似文献

Christopher Dahl 《Ocean & Coastal Management》1997,36(1-3)
The concept of integrated coastal zone management must be rethought to adapt it to the geography and social conditions of small islands. Because of their size, all small islands are in the coastal zone. Defining the whole of the island and its coastal waters as the management area may weaken a program's effectiveness. An alternative may be to adapt special area management planning to the socio-spatial organization found on small islands. Social conditions on islands, where people live in relatively small cohesive communities, makes resource user participation in planning and management particularly germane. This paper outlines an argument for small islands to use participation as a central strategy of coastal management based on experience with natural resource management efforts on the island of Pohnpei in the Federated States of Micronesia. 相似文献

Balancing aquaculture with other coastal interests: A study of regional planning as a tool for ICZM in Norway 总被引：1，自引：0，他引：1
Coastal zone planning at regional level has been introduced in Norway to deal with the problems of integration that coastal zone planning at municipal level has not been able to solve. In particular, this relates to coordination between the relevant sectors at regional level. The present article discusses the effects of different planning strategies at regional (county) level in terms of achieving integration between the interests of the aquaculture industry with those of other coastal interests. The findings are based on a study comparing the experiences in three counties. The authors argue that the individual county's choice of planning strategy influence the way in which the integrated coastal zone management (ICZM) is carried out. The more active the county authorities have been as a meta-governor in the planning and implementation processes, the higher level of integration is achieved. 相似文献

To meet the increasing demand of national spatial database infrastructure construction and application, a concept model of China‘ s coastal zone scientific data platform is established based on the information feature analysis of a compound dataset, consisting of remote sensing data and conventional data. Based on this concept model, the detailed logical database structure and the storage strategy of remote sensing data and their metadata using ArcSDE are designed. The complicated technology of multisources data combination in this research is crucial to the future coastal zone and offshore database construction and practical running, which will provide intelligent information analysis and technological service for coastal zone and offshore investigation, research, development and management. 相似文献

Assessment and management of coastal multi-hazard vulnerability along the Cuddalore-Villupuram, east coast of India using geospatial techniques 总被引：3，自引：0，他引：3
The current study area is coastal zone of Cuddalore, Pondicherry and Villupuram districts of the Tamil Nadu along the southeast coast of India. This area is experiencing threat from many disasters such as storm, cyclone, flood, tsunami and erosion. This was one of the worst affected area during 2004 Indian Ocean tsunami and during 2008 Nisha cyclone. The multi-hazard vulnerability maps prepared here are a blended and combined overlay of multiple hazards those affecting the coastal zone. The present study aims to develop a methodology for coastal multi-hazard vulnerability assessment. This study was carried out using parameters probability of maximum storm surge height during the return period (mean recurrence interval), future sea level rise, coastal erosion and high resolution coastal topography with the aid of the Remote Sensing and GIS tools. The assessment results were threatening 3.46 million inhabitants from 129 villages covering a coastal area 360 km2 under the multi-hazard zone. In general river systems act as the flooding corridors which carrying larger and longer hinterland inundation. Multi-hazard Vulnerability maps were further reproduced as risk maps with the land use information. These risk caused due to multi-hazards were assessed up to building levels. The decision-making tools presented here can aid as critical information during a disaster for the evacuation process and to evolve a management strategy. These Multi-hazard vulnerability maps can also be used as a tool in planning a new facility and for insurance purpose. 相似文献

The recent evolution of the coastal environment is characterized by an increase of human potential impacts: coastal zone is located at the cross-road of sectoral issues which give rise to a number of often competing uses. Today, the main challenges in the coastal environment management are not derived from “technical problems” but correspond to the global coastal management and to the means to harmonize the different uses. This new approach has generated the need to apply systemic concepts which are able to describe and analyze large and complex systems. In the coastal zone — and especially in sensitive environments such as tropical island surrounded by coral reefs, lagoons or boat channels — one of the major challenges is to conciliate the waste waters and pipe outfalls management and the ecological preservation. The paper presents the results which have been obtained with a global approach for the definition of a sustainable wastewater management strategy in highly sensitive coastal areas located in Mayotte, (Comoros archip, Indian Ocean). This example allows to explain and identify the necessary tools and essential procedures as hydrodynamic modelling or public participation. From this application, a procedure for a coastal environment assessment procedure is formulated and proposed. 相似文献
