中国自然灾害应急管理研究进展与对策

从中国自然灾害应急管理的现状出发,系统分析了自然灾害应急管理领域的研究进展,指出了中国自然灾害应急管理在理论和实践方面存在的问题.在此基础上,提出了中国自然灾害应急管理框架,认为建立适合中国国情的自然灾害应急管理体制是提高中国自然灾害应急管理的基础;应急预案的制定和实施是规范灾害应急管理,提高灾害紧急救援能力的关键措施;灾害信息快速准确的获取和评估是灾害应急管理的有效保障;建立实际可用的应急管理系统是提高灾害应急管理水平和工作效率的根本出路.     

中国自然灾害应急法律体系的数量差异分析

以《国家突发公共事件应急预案》中所明确的水旱灾害、气象灾害等7种自然灾害分类为依据,以万方数据平台查询到的自然灾害应急法律、法规、标准为基础,分析了这7种自然灾害现有相关法律法规文件的数量差异,由此得到了不同灾害在法律法规、标准和预案的数量结构上的差异,并分析了不同灾害对应的现有法律法规文件的完备性,提出了不同灾害法律文件在加强数量完备性方面的方向性的建议。对于协调中国不同类型自然灾害相关法律法规文件的数量及其平衡发展,提高自然灾害应急管理能力有一定参考意义。     

自然灾害强度的评估方法及应用——基于综合灾情指数的研究

自然灾害造成的损失通常表现在多个方面,为了客观、全面地评估自然灾害,需要综合考虑多种灾情因素,最终才能得到灾害的总体评估结果。综合灾情指数(SDI)是对一系列灾情评价因子进行归一化、加权求和,这样得到的定量化的灾害评估指数,能够综合反映灾情信息。阐述了具有通用性的综合灾情指数,并设计开发了综合灾情指数工具,该工具包括评价因子、设置权重、规范化灾情指数和综合灾情指数4个模块。以汶川地震为例,利用综合灾情指数工具,对地震重灾区的灾害强度进行了综合评估。通过分析评估结果,综合灾情指数的分布真实地反映了受灾的严重程度,显示出该工具具有较好的实用性和有效性。

综合自然灾害风险管理是目前国际上防灾减灾和灾害管理较先进的措施和模式，是针对各种自然灾害的全灾害的管理，是贯穿于灾害管理全过程，集中于灾害风险和承灾体脆弱性分析并强调多层面、多元化和多学科参与合作的全面整合的灾害管理模式。介绍了综合自然灾害风险管理的必要性、概念和本质，探讨了综合自然灾害管理的基本理论、对策及其实施过程和实施战略，在此基础上提出了对我国实施综合自然灾害风险管理的建议，为强化和推动我国综合自然灾害风险管理提供参考。     

Community cohesion after a natural disaster: insights from a Carlisle flood

This project analysed changes in community cohesion following a natural disaster. Data were collected from a flood‐affected community using a questionnaire survey. Analyses revealed that community cohesion was not predicted by the length of residence, or any other demographic characteristic of residents, but rather by a sense of community, community cognition and the degree of community participation. Cohesion alteration was not uniform, but varied along levels of hazard severity (degree of flood invasion). Cohesion increased in line with hazard severity at the initial flood stage, as residents recognised the importance of community unity and came together to cope with their losses. When the severity increased, residents transferred their focus to individual interests, which resulted in decreased cohesion. This project distinguishes itself in examining community cohesion in the wake of a natural disaster in the real world. Implications regarding community reconstruction and suggestions for hazard researchers are discussed accordingly.     

自然灾害风险区划图的一个潜在发展方向

由于自然灾害系统的复杂性及数据资料的不完备性,人们不可能精确估计任何自然灾害发生的概率,"概率值估不准"是现有超越概率风险区划图的致命弱点.简要回顾了针对这一问题已进行的提高估计精度和进行模糊风险计算的有关研究,并将模糊风险研究引入风险区划图的编制,给出了自然灾害软风险区划图的定义和一个初步的样式.讨论了这种风险图在体现风险值估不准方面,以及在为用户提供更多风险信息,为决策者提供调整余地等方面的优点.研究结果表明,软风险区划图是自然灾害风险区划图的一个潜在发展方向.为推进这一研究领域的发展,对今后的工作提出了一些建议.

Immediate and long-term assistance following the bombing of the US Embassies in Kenya and Tanzania

On 7 August 1998 truck bombs destroyed the US Embassies in Kenya and Tanzania.(1) The response in both countries was characterised by an absence of incident command, limited pre-hospital care, a disorganised hospital response and a lack of transportation for those injured. In the next five years USD 50 million was provided by the United States Agency for International Development (USAID) to alleviate the resulting suffering, support reconstruction and strengthen disaster preparedness capacity in the two countries. These two programmes have enhanced awareness of disaster management issues, improved training capacity, built response structures and provided material resources. Their design and implementation provide lessons for future disasters in developing countries. The assistance programmes evolved very differently. In Kenya the programme largely excluded the public sector and the potential for government coordination, while the Tanzanian programme concentrated heavily on central government and regional hospital structures-largely omitting the non-governmental or civil society sector. Excluding key stakeholders raises concerns about programme sustainability and the ability to respond effectively to future emergencies.     

Anatomy of an ambush: security risks facing international humanitarian assistance

The 2003 war with Iraq has generated security concerns that present unique challenges to the practice of providing international humanitarian assistance during war and conflict. Objective research studies on security management are lacking. However, case studies have proven to be an important education and training tool to advance situational awareness of security risks. These challenges are illustrated by an analysis of the events surrounding the first ambush of, and assassination attempt on, a senior US aid official in Baghdad. Before deployment to conflict areas, especially those characterised by insurgent activity, humanitarian providers must realistically assess the threats to life and to the mission. They must obtain pre-deployment situational awareness education, security training and optimal protective equipment and vehicles.     

中国自然灾害转移、安置的财政补助机制

简要分析了转移、安置在应急管理与救灾实践中的重要意义。在分析转移、安置要素的基础上，结合灾害脆弱性分析提出了转移、安置规模和程度模型，讨论了人为决策影响因素对模型的影响，较好地体现了自然因素和人为因素的综合作用。根据对转移、安置的发生进程的分析，提出了转移、安置分级的概念并进行了简单的分级，阐述了转移、安置中的资源需求。在这些工作的基础上，进一步分析了我国当前转移、安置财政补助机制的优缺点，提出了基于上述模型和分级标准的改进建议。     

Comparison of the expectations of residents and rescue providers of community emergency medical response after mudslide disasters

The integration of community resources is critical for emergency response. A thorough understanding of a community's requirements in advance is essential. This study examines communities that suffered mudslide disasters, and discusses expectations of the emergency medical response provided to the community from the perspectives of residents and rescue groups. The questionnaire used in the study was designed to adopt the Likert Scale for quantification purposes. Its content was divided into six categories based on emergency response. Both residents and rescue providers acknowledged that finance and reimbursement were the highest priority. Public information was regarded as the least important by both groups. Significant differences existed between the groups on patient care activities and supportive activities (P = 0.02 and 0.03, respectively), which were more appreciated by residents. We conclude that residents had higher expectations of evacuation, temporary relocation, lodging, food, and sanitary management than the rescue groups.     

The academic medical centre and nongovernmental organisation partnership following a natural disaster

The global response to the 12 January 2010 earthquake in Haiti revealed the ability to mobilise medical teams quickly and effectively when academic medical centres partner non-governmental organisations (NGO) that already have a presence in a zone of devastation. Most established NGOs based in a certain region are accustomed to managing the medical conditions that are common to that area and will need additional and specialised support to treat the flux of myriad injured persons. Furthermore, an NGO with an established presence in a region prior to a disaster appears better positioned to provide sustained recovery and rehabilitation relief. Academic medical centres can supply these essential specialised resources for a prolonged time. This relationship between NGOs and academic medical centres should be further developed prior to another disaster response. This model has great potential with regard to the rapid preparation and worldwide deployment of skilled medical and surgical teams when needed following a disaster, as well as to the subsequent critical recovery phase.

Fiji's worst natural disaster: the 1931 hurricane and flood

At least 225 people in the Fiji Islands died as a result of the 1931 hurricane and flood, representing the largest loss of life from a natural disaster in Fiji's recent history. This paper explores the causes of disaster and the potential for recurrence. The disaster occurred because a rare event surprised hundreds of people—especially recently settled Indian farmers—occupying highly exposed floodplains in north‐west Viti Levu island. The likelihood of a flood disaster of such proportions occurring today has been diminished by changed settlement patterns and building materials; however, a trend towards re‐occupancy of floodplains, sometimes in fragile dwellings, is exposing new generations to flood risks. The contribution of this paper to the global hazards literature is set out in three sections: the ethnicity, gender and age of flood fatalities; the naturalness of disasters; and the merit of choice and constraint as explanations for patterns of vulnerability.     

内蒙古雪灾保险费率的厘定——基于自然灾害系统理论的研究

中国巨灾保险赔款占直接经济损失的比率比国际平均水平低的多,2008年初南方雨雪冰冻灾害和"5.12"汶川地震两次巨灾过后,国家加紧推进巨灾保险体系的建立。其中,巨灾保险费率厘定是基础。基于自然灾害系统理论,构建了以危险性曲线和脆弱性曲线为核心的巨灾风险保险费率厘定方法体系,改进了以往农业保险仅从致灾因子角度厘定费率的片面性。最后,借鉴美国洪水保险、日本地震保险以灾种为对象(而非承灾体种类为对象)构建巨灾保险体系的优势,以雪灾保险为例,厘定了内蒙古12盟市雪灾保险费率。结果显示,位于中部地区的锡林郭勒盟雪灾保险费率最高,为3.10%;位于西部地区的阿拉善盟、乌海市雪灾保险费率最低,为1.09%。
