关于淤泥质海岸与粉沙质海岸界定的探讨

对以往淤泥质海岸和粉沙质海岸的界定方法进行了回顾和剖析,指出了其中的不足。并根据前人大量试验结果和现场资料,从泥沙粒径、絮凝因子、起动流速、含泥量等因素,结合欧美国家和我国海洋调查规范对泥沙的分类,将泥沙d50<0.016 mm,含泥量大于25%的海岸视为淤泥质海岸;0.016 mm≤d50≤0.12 mm,含泥量小于或等于25%的海岸视为粉沙质海岸,这种海岸的分类不仅与众多泥沙研究成果总体一致,而且包涵了海岸泥沙运动、港口淤积及清淤等组合因素,更贴近于港口工程实际。     

Saving the coast: The British experience

Abstract

This article outlines the steps that have been taken to conserve the coast of Great Britain. It treats the subject historically and emphasizes the ways in which unofficial and official bodies have interacted. Apart from a few very restricted areas, the shoreline is open to all people. The siting of houses, chalets, and huts is strictly controlled. Problems arise from time to time as to the location of nuclear stations, oil storage areas, and similar installations; these issues are settled in full discussions at official inquiries at which all interests—official, business, and conservation–are represented.     

The urban coast from a national perspective

Abstract

Viewing the urban coast from the national perspective one sees not only the sheer number and complexity of the federal programs involved but the lack of adequate coordination and the different often cross‐purpose missions. It goes without saying that to date, no one federal agency or program has been specifically charged with overseeing the urban coastal resource as an entity, nor is it likely that one will. However, national concern regarding various aspects of the urban coastal issues has been expressed. A very clear‐cut national interest has been constitutionally declared in navigation, defense, and interstate commercial activities, most of which affect the water area. A more diffuse though no less important national involvement can be traced through a number of federal activities which add up to considerable federal interest and investment in our urban coastal areas. Beginning in the early 1960s with waterfront related urban renewal activity for example the activities have accelerated more recently with such things as the administration's urban initiative, the Urban Recreation Study and the Urban Waterfront Study (HCRS), the Urban Parks and Recreation Recovery Program (HCRS), the Maritime Preservation Program (HCRS and NHT), public investment in harbor cleanup (EPA), shorefront access and planning (OCZM), special waterfront demonstration projects (OCZM), and the State Coastal Zone programs coming in line to mention a few. Building on the existing framework and growing enthusiasm there is an unexcelled opportunity to make incremental progress in creating a new and better urban environment by effectively managing this unique portion of the city—the urban waterfront.     

明代舟山海防被忽略之原因及其影响

有明一代,倭患一直是危害东部沿海的重大问题,其中浙江地区尤为严重。明朝虽然重视浙东区域的海防建设,但因保守的海防思想和舟山自身的局限,作为浙东门户的舟山的战略地位却被忽略,不仅使得舟山防御力量薄弱,也同样削弱了浙东地区的防御纵深,最终使得舟山沦为海盗、走私的大本营。而明代统治者对海洋重要性的漠视,也对后来中国的历史走向产生了重要影响。

The Quiet Revolution in Visual Resource Management: A view from the coast

Abstract

This introductory piece traces the growth of knowledge and activity associated with visual resource management in general. A specific framework of questions regarding methods of coastal zone visual resource management is presented. The state‐of‐the‐art in methodological studies is listed for each question, and the methodological questions are related to the major articles with the special issue of the Coastal Zone Management Journal. Major legal federal statutes, state statutes, and court cases are reviewed in light of visual resource management in the coastal zone. The remaining articles within the special issue that deal with integration of VRM into decision‐making are then arrayed against a management framework. This framework includes regulatory situations for (1) public land management and planning, (2) public projects involving private lands, and (3) public regulation of private projects.

广西北部湾沿海发现明代窖藏文物

2018年9月14日,广西北部湾沿海城市——防城港市一处海边基建工地出土了16件明代早期窖藏文物,包括9件铜釜、1件双耳铜镬、6件龙泉青瓷盘,都是实用器具。这批文物的出土为研究明代北部湾的历史提供了新的实物依据。与该批窖藏出土文物同类型的文物在防城港市沿海其他地点也有出土。通过对文物出土环境、器型和时代的分析,结合北部湾的历史背景,可对这些文物的所有者及使用背景等情况作出合理推测。     

VBA编程在土工击实试验中的应用

土工试验技术人员面对大量击实试验数据,采用手工描点、曲线尺绘图的办法,不仅工作量大繁琐,并且极易受个人因素影响,得出的试验结果可信度较差。本文直接在工程实际使用的击实试验电子表格中添加计算控件,应用数值分析的最小二乘法编写VBA程序,对土工击实试验数据进行高次方的曲线拟合处理,求解出曲线的趋势方程及相关系数,进一步求解出最优含水率和最大干密度。本方法使对土工试验数据整理与计算变得直观、方便、准确,而且可方便地移植到其他电脑中,能帮助土工试验人员准确高效地处理击实试验数据,减少计算误差。

Preservation of living and recreating opportunities on the coast

This article examines the progressive erosion of coastal living and recreating opportunities. It considers the possibility that such changes represent not a softening of concern over recreation and preservation by local decisionmakers, but a breakdown in the traditional system of checks and balances available in our allocative system. To this end, several methods for increasing the capability of local jurisdictions to render balanced land‐use decisions on the foreshore are examined, and suggestions are presented for increasing private opportunity for recreation and living on the coast, particularly over time.
