基于GIS的土地适宜性评价决策支持系统--以南京市江宁区淳化镇为例

传统的基于GIS建立的土地适宜性评价系统缺乏对空间问题决策的支持能力,而GIS与DSS技术集成建立土地适宜性评价决策系统一方面可以实现对空间数据的管理和分析,另一方面可以利用模型进行辅助决策,有利于解决与空间有关的决策问题。以MapInfo Professional 6.0为基础平台,以Visual 〖XC夏敏字1.TIF,JZ〗6.0为开发工具,建立了一个土地适宜性评价决策支持系统,该系统包括数据库系统、模型库系统、知识库系统以及人机接口4个部分,具有数据输入输出、图属互查、数据空间分析和辅助决策等功能。系统成功应用于南京市江宁区淳化镇农地适宜性评价实践中,应用结果表明系统能为决策者提供多种决策方案,同时又集成了GIS的数据管理和空间分析功能,满足土地适宜性评价的要求,有推广使用的价值。

Civilians under fire: evacuation behaviour in north Israel during the Second Lebanon War

This paper seeks to understand evacuation behaviour in a case of spontaneous evacuation. During the Second Lebanon War of 2006, more than one‐third of residents in north Israel spontaneously evacuated—the remainder stayed in situ. Using a telephone survey of 665 respondents residing in north Israel, we were able to characterise the behaviour of evacuees and non‐evacuees. The main reasons cited for evacuating were fear of injury to self or family, the effect on children, inability to remain in a protective space, and family pressure. The main reasons cited for remaining at home were no suitable alternative, did not perceive a high level of danger, had to go to work, and there is no place like home. There were no significant differences with regard to most socio‐demographic characteristics of the population. These findings should aid emergency managers in preparing the population for a future emergency and in engaging in effective dialogue with the population during an emergency on the evacuation option.     

基于非结构模糊决策支持系统的建筑施工安全管理体系研究

基于建筑施工特点和前人的研究,确定建筑施工的安全管理要素及决策准则。运用非结构模糊决策支持系统确定建筑施工安全管理体系中各要素的权重,从而对各要素进行优先级排序。研究结果表明:建筑施工安全管理体系中各要素优先级排序为事故隐患排查与治理、现场监督、安全宣传、各级管理人员参与、安全教育培训、安全审查、建立健全安全政策。该研究为建筑企业进行资源优化配置提供了重要的依据。     

基于GAHP-BOCR解决瓦斯隧道安全施工决策问题

施工单位依据实践经验提出了不同于《铁路瓦斯隧道技术规范》的施工措施,为了评价不同施工措施的优劣性,选用灰色层次分析法和利益-机会-代价-风险模型。首先建立瓦斯隧道安全施工评价准则体系,运用灰色理论处理数据,得到准则和子准则对于瓦斯隧道安全施工的权重影响值;其次评价每个子准则对于BOCR属性值,得到BOCR对于总目标的影响程度,并对每个施工措施的B、O、C、R进行评价得出综合计算结果;最后对不同施工措施提出相应的意见。     

生活必需品现场保障数据系统的设计与实现

生活必需品现场保障数据系统是面向我国重特大灾害事件应急救灾物资保障的重大需求,以水、食品、生活用品等生活必需品应急物资为研究对象,针对生活必需品应急保障装备和技术平台支撑不足的问题,开发了生活必需品保障专用系统。该系统基于ASP.Net、RFID、二维条形码、ANDROID终端开发平台等多种信息化和网络化技术手段,实现了生活必需品出入库管理、库存信息统计分析、补给物资物流信息跟踪、需求信息辅助生成、保障对象管理和物资分配模型管理、物资分配方案辅助生成等功能。该系统在物资库存管理的基础上,通过对库存信息进行统计、对预计消耗信息进行基于模型的分析、对预计货物补充信息进行跟踪,对需求报送信息进行辅助生成,实现了对生活必需品库存变化的全过程进行跟踪,并可以通过在一定范围内动态调整物资分配模型,动态调整需求报送数量实现了对生活必需品库存的优化管理。生活必需品现场保障数据系统面向灾害现场的生活必需品物资存储与分配管理,并且与商务部门的后台物资调度系统无缝整合,成为全国应急生活必需品物资保障大平台的重要组件。     

Decision‐making and evacuation planning for flood risk management in the Netherlands

A traditional view of decision‐making for evacuation planning is that, given an uncertain threat, there is a deterministic way of defining the best decision. In other words, there is a linear relation between threat, decision, and execution consequences. Alternatives and the impact of uncertainties are not taken into account. This study considers the ‘top strategic decision‐making’ for mass evacuation owing to flooding in the Netherlands. It reveals that the top strategic decision‐making process itself is probabilistic because of the decision‐makers involved and their crisis managers (as advisers). The paper concludes that deterministic planning is not sufficient, and it recommends probabilistic planning that considers uncertainties in the decision‐making process itself as well as other uncertainties, such as forecasts, citizens responses, and the capacity of infrastructure. This results in less optimistic, but more realistic, strategies and a need to pay attention to alternative strategies.

Book reviews and notices

The aim of sustainable development is to balance social, economic, and environmental needs. In order to justify the decisions they make, stakeholders must quantify the different impacts found in the operations and developments of companies and/or projects throughout their life cycle. However, as some areas are subjective in nature, the quantification process of the different impacts and the assessment of sustainable development performance become arduous tasks of development, validation, and application of scientific and empirical methods with the intrinsic objective of finding an agreement among the involved parties (i.e., stakeholders). Several environmental and sustainability assessment tools, instruments, processes, and methodologies have been developed; rating systems stand out and have gained attention and credibility, as demonstrated by the vast number of certified projects around the world and the widely-known usefulness and advantages of their application. The Wa-Pa-Su project sustainability rating system presents an integrated approach to sustainability assessment by integrating three distinctive areas of knowledge: (1) sustainable development theory and fundamentals supports the ultimate goal of the rating system, which is to contribute to sustainability, with the aim of finding a path to balance social, economic, and environmental needs; (2) continual performance improvement becomes essential due to the duration of the projects, as it is critical to allow organizations or projects to improve performance over time; and (3) multi-criteria decision analysis assists with the assessment process through stakeholder engagement and participation, and the design and implementation of a criteria weighting system.
