基于界壳理论的交通环境系统运行机理初探

从界定交通环境系统的界壳论域出发,分析交通环境系统的界壳支撑结构和界壳行为,定义界壳开放度、界壁抵抗力以及界门开关速度、界门交换率等描述交通环境系统界壳功能的参数。研究表明,界壳论在降低路网建设对交通环境系统破环程度、调控交通污染排放与环境自净化能力的协调运行等方面具有较好的应用前景。     

加利福尼亚州车辆合乘系统运行效果

为了解加利福尼亚州HOV系统的运行效果,基于交通量检测器收集的数据,对HOV系统进行全面分析、评价。最终得到4个主要结论：1）与多条普通车道构成的高速公路相比,包含1条HOV车道的高速公路损失了20%的通行能力;2）HOV车道通常处于两种运行状态,一种是HOV车道未被充分利用,另一种是HOV车道处于超负荷、降级运行状态;3）HOV车道未显著提高小汽车合乘比例;4）在一个相当出色的交通管理系统中,HOV车道并未从整体上缓解道路交通拥堵状况。

Placing dryports. Port regionalization as a planning challenge - The case of Hamburg, Germany, and the Süderelbe

This paper emphasizes dryports in the context of port regionalization. It specifically deals with dryports as a challenge for planning, policy and metropolitan governance in the vicinity of seaports. The starting point is the ongoing spatial shift of terminals, distribution centres and port related developments towards the hinterland of mainports and the associated planning conflicts, raising negative impacts such as congestion, land consumption, land use conflicts and neighbourhood conflicts. The paper discusses these challenges against the empirical case of the Süderelbe-region in the Southern hinterland of the port of Hamburg, Germany. It focuses on the often neglected yet highly controversial issue of land use and related traffic flows. Further it reveals how these conflicts are being managed at the regional level. The main contention of the paper is that port regionalization triggers substantial planning conflicts different from those that are known from core port areas, due to the associated demand for land and infrastructure and also as a result of the often poorly developed institutional framework to solve these problems.     

Planning for Cruise Ship Resilience: An Approach to Managing Cruise Ship Impacts in Haines,Alaska

Resilience theory has management implications useful when planning for cruise ship tourism. In small coastal communities, cruise ships often provide welcomed economic incentives that can bolster a waning economy. However, in some coastal communities, the magnitude and intensity of passenger visits can reduce social resilience and induce an economic regime shift that leads to rapid socioeconomic reorganization. The implications of such a regime shift are a loss of economic diversity, reduced social resilience, and a loss of social capital. Planning for cruise ship resilience increases the likelihood of successful coping strategies and addresses the socioecological changes inherent to a cruise ship destination. Both Holling's adaptive cycle and the four principals for building resilience established by Berkes and Seixas are fundamental to a successful management plan.     

Public opinion and the environment: Ecology,the coastal zone,and public policy

Abstract

In a public opinion survey conducted in Santa Barbara county, California, respondents were interviewed regarding their feelings on coastal zone development, within a context of broader environmental and political issues.

A high degree of expressed concern for the environment was found, but the data also indicate a widespread reluctance to allocate a greater share of personal income to improve environmental quality.

Among the issues dealt with are citizen views on environmental problems, the effectiveness of government in the environmental field, offshore oil drilling, and coastal zone development.

The results show that on each of the issues analyzed, a person's education, age, and the extent of his political participation are the major factors which determine his concern for the environment. Additional variables appear to have some significance in determining attitudes toward local environmental projects and perceptions of government.

Offered are implications of the findings for the future of organized action on environmental problems.
