社会资本对山区居民山洪灾害应急避险能力的影响研究*

为研究社会资本对山区居民应急避险能力的影响,在广泛调研的基础上采用结构方程模型分析社会资本与山区居民应急避险能力各要素之间的作用关系。结果表明:个人网络对避险知识和避险意识有显著的正向影响,对避险行为影响不显著;信任与避险知识和避险意识呈显著的正向影响,而与避险行为呈反向影响,但信任可以通过避险知识和避险意识间接正向影响避险行为;互惠对避险知识影响不显著,但互惠与避险意识和避险行为存在显著的正向关系;避险知识和避险意识对避险行为呈显著正向影响,其中避险意识对避险行为影响更为显著。因此可以通过增加山区居民社会资本的方式提高山区居民山洪灾害应急避险能力。     

汶川地震极重灾区地形起伏度特征及其与生态环境受损关联分析

采用DEM数据对汶川地震极重灾区地形起伏度特征分析,海拔高度和地形起伏度总体上是南西高,北东低。5km×5km单元地形起伏度〉1000m的区域面积占27．98％。0．5km×0．5km单元〉100m的区域面积占50．63％。在8．0级主震和6．4级余震震中之间典型区段剖面0．5km间隔分析中,南西段起伏度大于北东段,南西段起伏度〉200m区段占全段14．84％,北东段仅占6．64％。地震导致生态环境受损程度的差异与地形起伏度的差异在空间分布上有一定的重合,具有高起伏度的南西段生态系统破坏面积占总破坏面积的88．55％,新增水土流失面积占新增总面积的70．99％。地震灾区地形起伏度是生态环境遭受严重破坏致灾关联因素之一。     

极端温度下帐篷内部热环境适应性实验及模拟研究*

为揭示民用救灾帐篷热环境适应性变化规律,通过大尺度环境气候舱构建高温与低温环境,采用Ansys Fluent商用软件代码进行仿真验证,并对帐篷蓬围结构和内部热环境分布变化规律进行实验与数值模拟。研究结果表明:使用大尺度环境舱直接进行模拟帐篷内外热环境变化可行,其内部热环境变化规律与实验基本一致;帐篷特殊的篷围结构导致高温环境下帐篷内部温度高于外界,帐内人员头部和脚部温差可达5 ℃,低温环境下帐篷同一高度横向区域温度对称分布,在中心区域温度较低,边缘和中心温差近8 ℃。     

辛置煤矿水力压裂卸压增透影响半径数值模拟研究

随着开采深度的增加,辛置煤矿瓦斯涌出量显著增大。为了提高瓦斯抽采效率,拟采用水力压裂卸压增透技术。理论分析了水力压裂对煤层的卸压增透作用,基于此利用RFPA模拟软件对辛置煤矿2-559回采工作面水力压裂卸压增透进行了数值模拟。研究表明,水力压裂主要在以下3个方面对煤体起到增透作用:使煤体卸压、提高煤层透气性;湿润煤体,增加塑性;改善瓦斯抽放环境。辛置煤矿2-559回采工作面水力压裂所需压力约为15MPa,压裂半径为5-6m,以此可以初步确定现场施工过程中水力压裂钻孔间距以不大于10m为宜。     

试论我国城市应急软能力提升路径——基于2016年武汉洪涝灾害的理性思考

城市应急能力建设是保障城市公共安全的关键环节。当前我国城市应急能力建设重“硬件”轻“软件”,导致在城市灾害应对过程中效果不佳。选取受2016年南方洪涝影响严重的武汉市作为研究对象,对城市内涝灾害治理过程中应急“软能力”的现状及功能进行剖析,提出在制度适应、风险管理以及理念协调等方面的重构思想,并论述城市应急“软能力”的提升路径:建立健全防灾导向的城市规划制度,推进协同导向的城市灾害风险管理,加强完善教育导向的城市灾害文化建设。     

Arts as a vehicle for community building and post‐disaster development

Use of the arts in international aid is common in an ad hoc form, but it has not been systematically theorised or evaluated. The arts have the potential to be a culturally contextualised and sustainable intervention for adults and children in the aftermath of war or disaster. On the micro level, the arts are a method to enable the retrieval and reprocessing of traumatic memories that are often encoded in images rather than in words. On a macro level, they can help to reconstruct a group narrative of a disaster as well as mobilise people back into control of their lives. This paper researches a long‐term project using arts in Sri Lanka following the civil war and tsunami. A central finding is the need to understand arts within their cultural context, and their usefulness in strengthening the voices and problem‐solving capacities of the victims of the disaster.     

Enhancing community-based disaster preparedness with information technology

A critical component of community-based disaster preparedness (CBDP) is a local resource database of suppliers providing physical, information and human resources for use in disaster response. Maintenance of such a database can become a collaborative responsibility among community-based non-governmental organisations (NGOs) and public and private community organisations. In addition to mobilising resources, this process raises awareness within the community and aids in assessing local knowledge and resources. This paper presents the results of a pilot study on implementing a community-based resource database through collaboration with local American Red Cross chapters and public and private community organisations. The design of the resource database is described. The resource database is accessible via the internet and offline using laptops and handheld Personal Digital Assistants. The study concludes that CBDP is strengthened through a combination of appropriate information technology and collaborative relationships between NGOs and community-based organisations.     

Collaborative emergency management: better community organising, better public preparedness and response

Community coordination requires communication and planning of precautions to take when faced with a severe threat of disaster. The unique case of the four Florida hurricanes of 2004--Charley, Frances, Ivan, and Jeanne--is used here to assess community responses to repeated threats of hurricanes. The paper examines how effectiveness in coordinating community disaster response efforts affects future public preparedness. The findings suggest that pre-season planning, open communication between emergency managers and elected officials, and the use of technology all had a significant impact on community responses. The repeated threat scenario indicates that emergency managers must work vigilantly to keep residents informed of the seriousness of a situation. The study describes how emergency managers in Florida countered public complacency during four hurricanes in six weeks. The strategies identified as useful by public managers in the context of hurricanes are applicable to other natural and man-made disasters.     

The impact of the 2004 tsunami on coastal Thai communities: assessing adaptive capacity

The suddenness and scale of the 26 December 2004 tsunami and the challenges posed to affected communities highlighted the benefits of their members having a capacity to confront and adapt to the consequences of such a disaster. Research into adaptive capacity or resilience has been conducted almost exclusively with Western populations. This paper describes an exploratory study of the potential of a measure of collective efficacy developed for Western populations to predict the capacity of members of a collective society, Thai citizens affected by the 2004 tsunami, to confront effectively the recovery demands associated with this disaster. Following a demonstration that this measure could predict adaptive capacity, the role of religious affiliation, ethnicity and place of residence in sustaining collective efficacy is discussed. The implications of the findings for future research on, and intervention to develop, adaptive capacity among Thai citizens in particular and collectivist societies in general are discussed.
