江苏沿海港口吞吐量影响因素及预测分析

目前江苏沿海地区综合开发已上升到国家发展战略层面,沿海港口建设正在迅猛开展。港口吞吐量的预测对于港口的建设有着极其重要的意义。以港口和腹地之间的互动关系为出发点,分析了可能影响江苏沿海港口吞吐量的若干因素,采用主成分分析法提取了过去10年影响港口吞吐量的最关键因素,剖析了江苏港口发展的内在影响机理,并提出了基于影响机理的预测模型。最后使用模型对江苏港口吞吐量进行验证分析,模型为江苏沿海港口新一轮发展提供了有力的数据支撑。     

沿海集装箱港区港内锚地面积确定方法

设置港内锚地,是沿海集装箱港区缓解航道拥堵,提高港口服务水平的有效途径之一。为完善港内锚地面积确定方法的理论研究,基于计算机仿真技术,建立设置港内锚地的沿海集装箱港区船舶航行作业系统仿真模型,研究计算期内可能同时占用港内锚地的船舶数量及船型组合;计算不同锚泊方式下所需的港内锚地最大面积。仿真结果与分析结论为沿海集装箱港区港内锚地的规划建设及改造扩建提供参考。     

滨海核电站防洪体系的设计优化研究

目前我国已在核电站选址及防洪要求方面初步建立起了法规和标准体系,今年发生在日本的福岛核事故再次凸显了滨海核电站防洪设施的重要性.以国内、外几个核电站工程为例,针对进一步加强滨海核电站防洪设计、优化综合性防洪措施、建立防洪预警系统和防洪应急程序等方面的技术问题进行深入探讨,提出相关见解和对今后工作的建议.     

泛地主港模式对浙江沿海港口的借鉴作用

以嘉兴港实践地主港模式作为实证研究对象,对其成效和存在的问题进行剖析,提出以泛地主港模式进行港口建设的思路,介绍泛地主港模式的运作方式和程序,就泛地主港模式对浙江沿海港口的借鉴作用进行论述.     

船型组合对沿海散货港区航道通过能力的影响*

基于到港船型的多样性和随机性,建立不同船型组合下的沿海散货港区船舶航行作业系统仿真模型,定义到港船舶吨级的加权平均值为船型组合的特征吨级,研究船型组合对港口航道通过能力的影响。仿真结果表明,船型组合对沿海散货港区航道通过能力有显著影响;航道通过能力与船型组合的特征吨级之间呈指数函数关系;并且通航历时越大,航道通过能力对船型组合越敏感。

Book review

Since society values both, it is desirable to implement management solutions that protect these species while minimizing social and economic impact, even if it is not required by law. This case study analyzed management issues relating to sea turtle bycatch in a small-scale gillnet fishery that targets flounder in Pamlico Sound, North Carolina. A primary goal of this research was to examine the feasibility of achieving both biological and social objec­tives by determining if any compatibility existed between those different objectives. This was done by cross-referencing quantitative social data with management measures that would achieve biological goals. Qualitative data also provided insight into scientific issues, obstacles to management effectiveness, and potential solutions. Overall, this article discusses the possibility of implementing solutions that reflect multiple societal values while operating under the Endangered Species Act.     

Two-MPA Model for Siting a Marine Protected Area: Bahamian Case

This article recommends the parallel but separate modeling of nature-based and people-based marine protected areas (MPA) before the design and siting stages of establishing an MPA. Separate but simultaneous modeling of ideal nature and people MPAs permits each to be maximized for its own variables and subsequently compared to identify conflicts and agreements. The case that supports this recommendation is in the Commonwealth of the Bahamas, where the study conducted 572 interviews with people from six traditional settlements in the central Exumas Islands and Cays. The research is focused on why members of these settlements differentially responded to three nearby national MPA proposals.     

Governance Responses to Rapid Growth in Environmentally Sensitive Areas of Coastal Australia

The twin forces of rising affluence and population are altering coastal communities around the world. High amenity, environmentally sensitive areas—particularly attractive, non-metropolitan coastal environments—are witnessing a tidal wave of in migration from former urbanites. As a result, these communities are struggling to accommodate growing numbers of people with urban tastes and rural dreams in areas with governance structures and physical infrastructure designed for occasional tourists. This article looks at how governance frameworks in coastal Australia respond to the profound environmental, social, and cultural implications of this process. We offer a typology of non-metropolitan coastal growth settings—from exurban contexts to isolated coastal hamlets—and identify the main environmental, social, economic, and governance issues they face. We then outline the policy and legislative framework governing coastal areas in Australia and show how this framework is interpreted at the local level through an analysis of five local plans covering different coastal settings.
