对杭州市部分自然灾害应急预案完备性评价的实证研究

采用故障树分析方法,从灾害的预防与应急准备、监测与预警、应急响应、后期处理4个方面,对2008年以前杭州市编制的部分自然灾害应急预案的完备度进行评价。结果表明:各类自然灾害应急预案的完备度不一,一些应急预案具有较高的完备度,而一些应急预案完备度偏低;大部分应急预案在灾害监测与预警方面具有较高的完备度,部分应急预案在灾害预防与应急准备、灾害后期处理完备度偏低;各应急预案中志愿者队伍的建设、灾害风险评价、应急人员的安全防护、灾后的保险理赔、重要设施的安全防护、启动应急避难场所等基本事件的缺失率较高,反映了部分应急预案编制过程中灾害全过程管理理念的缺失。

一种基于事故后果的重大危险源安全规划方法

介绍了一种基于事故后果的重大危险源安全规划方法。该方法详细阐述了“最坏”事故情景选择、事故后果阈值确定及后果伤害范围划分的方法,以危险源周边人群作为主要脆弱性目标,通过分析事故后果伤害范围和目标的脆弱性级别确定危险源与周边环境的兼容性。另外,以危险品仓储区为例,利用该方法对仓储区可能发生的事故后果影响范围进行计算,对仓储区选址的可行性进行分析。本文提出的重大危险源安全规划方法可为城市土地使用及危险源的安全规划提供参考。     

基于内容分析法的土地利用总体规划目标偏好研究

土地利用总体规划需要统筹区域发展多元目标以增强对区域发展的指导力和约束性,因此全面了解我国土地利用总体规划的政策目标偏好,能为优化规划技术方法和改革规划管理体制提供政策参考。鉴于此,本文在分析我国土地利用总体规划多元目标及其关系的基础上,采用内容分析法基于全国土地利用总体规划纲要进行词频挖掘构建目标偏好测量维度及体系,进而对两轮省级土地利用总体规划文本进行目标偏好的定量测度,结果表明:(1)土地利用总体规划是多目标规划,通过内容分析法可以构建由经济、社会、生态三大目标构成的目标偏好测量体系;(2)从目标偏好排序来看,三大目标中社会目标始终是两轮土地利用总体规划的首要偏好目标,生态目标是土地利用总体规划的次要偏好目标,经济目标排在最后;同时相比上轮规划,本轮规划耕地保护子目标次序提前,土地整治子目标次序推后;(3)从目标偏好程度来看,社会目标的首位偏好程度有所下降,但其中耕地保护子目标的首位偏好度明显上升;生态目标和经济目标的首位偏好程度基本不变,总体而言本轮规划三大目标偏好程度的差异缩小。研究结果说明,我国土地利用总体规划始终坚持以耕地保护为核心的社会目标偏好,符合其是国土资源管理部门主导的部门规划的定位;虽然土地利用总体规划对经济、社会、生态三大目标的偏好程度差异缩小,但其若要在空间规划体系中发挥更大的作用,还需要通过优化规划技术和改革规划管理体制进一步均衡经济、社会、生态目标,以承担起统领全区域空间发展的要求。     

Integration of biodiversity in urban planning instruments in developing countries: the case of Kumasi Metropolitan Assembly,Ghana

There is a growing concern about integrating biodiversity into urban planning, yet, discussions are concentrated on science-informed planning in general. Few have explored the integration of biodiversity in specific planning instruments, especially in African cities. This paper examines how and what components of biodiversity are integrated into master plans, medium-term plans, building codes, zoning codes and permits in Kumasi City, Ghana. There is limited integration of biodiversity in most planning instruments as they were mostly designed on the basis of health, safety and economy. Allied to lack of funding and public participation, biodiversity in Kumasi is under significant threat from rapid urban development. Creating an opportunity for popular participation and decentralizing the planning system could set the preconditions for local integration and revision of instruments. Simplifying the definition of biodiversity could increase local planners’ appreciation, understanding and their ability to make use of biodiversity data.     

Evaluating soundscape intentions in landscape architecture: a study of competition entries for a new cemetery in Järva,Stockholm

While soundscape is increasingly acknowledged within landscape planning and design discourse, there is little research that clarifies how soundscapes are actually dealt with in landscape architecture practice – partly owing to methodological insufficiencies. This paper, therefore, describes a model for evaluating soundscape treatment in landscape design proposals, focusing on three key aspects. With the dual aim of testing the model, and learning more about how soundscape is approached in practice, the paper spotlights a major design competition for a new cemetery in Sweden. The model proved fruitful and easy to apply. It showed that only limited attention was paid to soundscape in the competition as a whole, and was a useful means of pinpointing proposals where soundscape was fully considered as a design feature; one competition entry that did so is described in the paper. Discussions cover design practice, trends in the competition and model application.     

Cause,catalyst or conjunction? The influence of the Habitats Directive on policy instrument choice in Member States

In the process of implementing EU policy, Member States sometimes introduce new policy instruments in cases where this is not obligatory. To better understand this phenomenon, this paper reviews three cases in which new instruments emerged and develops a methodology to trace back the influence of EU Directives on instrument choice. The method is illustrated by a narrative of the emergence of new management planning instruments during the implementation of the EU Habitats Directive in three EU Member States: Finland, Hungary and the Netherlands. Three key features of a policy instrument are defined, namely, its authoritative force, action content and governance design. These are used to measure the contribution of the Habitats Directive compared to other potential explanatory causes for the emergence of the new policy instrument. In all three reviewed countries a nested causal relationship between the Habitats Directive and the introduction of the new policy instrument is identified. Based on the relative contribution of the Habitats Directive to the emergence of the new instrument a distinction is made whether the Directive acted as a cause, catalyst or if conjunction occurred.

A Question of Boundaries: The Importance of “Revenuesheds” for Watershed Protection1

Patterson, Lauren A., Jeffrey Hughes, Glenn Barnes, and Stacey I. Berahzer, 2012. A Question of Boundaries: The Importance of “Revenuesheds” for Watershed Protection. Journal of the American Water Resources Association (JAWRA) 48(4): 838‐848. DOI: 10.1111/j.1752‐1688.2012.00655.x Abstract: Watersheds transcend jurisdictional boundaries; raising important questions of who should pay for watershed protection, and how can watershed governance be funded? The responsibility and cost for watershed protection has progressively devolved to local governments, resulting in additional negative externalities and financing challenges. Watershed governance structures have formed at the scale of the watershed, but they often lack the financing mechanisms needed to achieve policy goals. Financing mechanisms via local governments provide a reliable source of revenue and the flexibility to address watershed specific issues. We develop a “revenueshed” approach to access the initial challenges local governments face when seeking to finance trans‐jurisdictional watershed governance. The revenueshed approach engages local governments into discussion and implementation of financial strategies for collaborative watershed governance. Legislation places water quality regulations primarily on local governments inside the watershed. The revenueshed approach extends the financial and stewardship discussion to include local governments outside the watershed that benefit from the watershed. We applied the revenueshed approach to the Mills River and Upper Neuse watersheds in North Carolina. Mills River had a partnership governance seeking revenue for specific projects, whereas the Upper Neuse sought long‐term financial stability to meet new water quality legislation.
