中小学校作为避难疏散场所的规划对策研究

中小学校具有布局有效,设施齐备,广为人知,生活方便,互救互联,便于疏散等多方面的优点,其作为可利用的应急避难场所重要资源,在城市规划中占有重要的位置。城市因为人员密集,中小学校的利用是满足紧急避难要求所必需的,但是在汶川、玉树等特大地震的抗震救灾实施工作中,暴露出很多建设、规划以及配置等多方面的问题。基于此,通过对中小学校作为避难疏散场所的必要性和有效性进行研究,并从不同角度,不同层面的有效避难面积数据进行统计和分析,结合我国的城市规划和避难疏散规划的现状和相关标准进行比对,研究我国中小学校建筑和规划在避震疏散结构体系和避灾要求方面存在的问题,提出适宜于城市规划和建设的中小学校避难疏散利用对策,为今后中小学校的防灾规划提供依据和参考。     

农村灾害避难场所布局规划评价研究——以四川省小鱼洞镇为例

灾害避难场所不仅在灾中或灾后能为农村灾民提供一个临时安置或生存场所,而且更是农村整合其有限资源开展防灾减灾工作的平台,在农村社区减灾中工作发挥着重要的作用,然而相关研究工作较少。以四川省彭州市小鱼洞镇为例,通过对政府既定的避难场所进行安全性、通达性、收容性、生活性等分析,综合评价这些避难场所的布局合理性。以期为该区避难所的进一步建设提供科学依据,也为农村灾害避难所的规划和评价提供参考实例。     

Cyclone shelters and their locational suitability: an empirical analysis from coastal Bangladesh

Bangladesh is one of the poorest and the most disaster‐prone countries in Asia; it is important, therefore, to know how its disaster reduction strategies are organised and planned. Cyclone shelters comprise a widely acceptable form of infrastructural support for disaster management in Bangladesh. This paper attempts to analyse empirically their use during cyclones in a sample study area along the southwest coastal belt of the country. It shows how the location of a cyclone shelter can determine the social power structure in coastal Bangladesh. The results reveal that the establishment of cyclone shelters in the studied communities is determined by neither a right‐based nor a demand‐based planning approach; rather, their creation is dependent on the socio‐political affluence of local‐level decision‐makers. The paper goes on to demonstrate that socially vulnerable households (defined, for example, by income or housing conditions) are afforded disproportionately less access to cyclone shelters as compared to less socially vulnerable households.     

城镇防灾避难场所规划研究

城镇防灾避难场所是城镇灾后应急避难、救援、恢复重建的重要组成部分,也是城镇平时功能的主要构成部分。首先按照应对灾害的主要类型,将避难场所分为气象型避难场所和地质型避难场所,相对应的为建筑型避难场所与场地型避难场所。继而与城市规划中的用地性质相关联,从防灾避难的角度将城镇用地划分为"靶区""防灾避难据点"与"防灾避难通道"。总结城镇防灾避难空间结构的组成要素、组构原则与组成方式,并以三种模式进行模型化构建。进而概括了城镇防灾避难场所的规划要点、规划内容与技术路线,并以深圳防灾避难场所规划加以佐证。得出了结论:防灾避难场所是城镇整体空间不可分割的一部分;城镇防灾避难空间规划应从城镇整体空间结构出发,合理规划防灾避难场所与防灾避难通道,优化用地功能与规模,提升城镇整体的防灾避难能力。     

Collaborative modelling‐based shelter planning analysis: a case study of the Nagata Elementary School Community in Kobe City,Japan

This study, based on a questionnaire survey and workshops, and with a focus on the impact of an earthquake on the Nagata Elementary School Community in Kobe City, Japan, develops a collaborative model to assess the allocation of residents to shelters. The current official allocation plan is compared with three alternative allocations developed within the framework of this model. The collaborative model identifies accessibility, amenity, capacity, connectivity, continuity, security, and stability as the basic, necessary criteria for shelter planning. The three alternative allocations are very similar to the local residents’ own choice of shelters, but they are quite different from the current official allocation plan, which is supposed to be followed but has achieved relatively low satisfaction among households. The proposed collaborative approach provides an effective tool to assess the officially determined allocation plan by taking into account the viewpoints of local residents, and the results are useful for enhancing community evacuation planning.     

Need for adaptation: transformation of temporary houses

Building permanent accommodation after a disaster takes time for reasons including the removal of debris, the lack of available land, and the procurement of resources. In the period in‐between, affected communities find shelter in different ways. Temporary houses or transitional shelters are used when families cannot return to their pre‐disaster homes and no other alternative can be provided. In practice, families stay in a standard interim solution for months or even years while trying to return to their routines. Consequently, they adapt their houses to meet their midterm needs. This study analysed temporary houses in Chile and Peru to illustrate how families modify them with or without external support. The paper underlines that guidance must be given on how to alter them safely and on how to incorporate the temporary solution into the permanent structure, because families adapt their houses whether or not they are so designed.

城市避难场所相关研究进展与展望

在阅读大量国内外文献基础上,对避难场所相关概念进行归纳总结,梳理避难场所相关研究的脉络,分析避难场所相关研究的演变与发展。重点对评价和选址两大研究主题进行深入探讨与归纳总结。已有研究成果较为丰富,但仍存在不足之处。目前,避难场所相关概念较多,尚无共识。已有研究对象多局限于绿地,而对城市中其他能够保障居民灾时安全的开敞空间挖掘不够。空间布局研究较为零散,方法有待更新,评价结果难以深入到城市内部空间结构,且忽略了居民避难行为的影响力。未来应①着力探索高效、规范的识别方法,明确城市中能真正保障居民灾时安全的避难空间;②强化灾害行为学研究,基于居民灾时行为特征进行避难空间评价与选址;③探讨避难空间在大城市蔓延与土地利用系统变化过程中的空间布局、演变特征与驱动力。     

Special needs hurricane shelters and the ageing population: development of a methodology and a case study application

Recent experience of hurricanes, particularly in the southeast United States, has heightened awareness of the multifaceted nature of and the challenges to effective disaster relief planning. One key element of this planning is providing adequate shelter at secure locations for people who evacuate. Some of these individuals will have ‘special needs’, yet there is little research on the relationship with shelter space. This study designed a geographic information systems‐based network optimisation methodology for the siting of special needs hurricane relief shelters, with a focus on the transportation component. It sought to find new locations for shelters that maximise accessibility by vulnerable populations, given capacity constraints, concentrating on the ageing population. The framework was implemented in a medium‐sized metropolitan statistical area in the state of Florida where data suggest a possible deficit in special needs shelter space. The study analysed options for increasing special needs shelter capacity, while considering potential uncertainties in transportation network availability.

Needs assessment of the displaced population following the August 1999 earthquake in Turkey

In August 1999 a major earthquake struck north-western Turkey. An assessment followed to identify the immediate needs of the displaced population. A random cluster sample of displaced families living in temporary shelter outside of organised relief camps was designed. Representatives of 230 households from the four communities worse affected by the earthquake were interviewed. Most families lived in makeshift shelters (84 per cent), used bottled water (91 per cent), obtained food from relief organisations (61 per cent), had access to latrines (90 per cent), had a member on routine medication (53 per cent) and obtained information by word of mouth (81 per cent). Many respondents reported having family members who were over the age of 65 (32 per cent) or under age three (20 per cent), who were pregnant (6 per cent), or who had been ill since the earthquake (64 per cent). The greatest immediate need reported by most families was shelter requirements (37 per cent), followed by food (23 per cent) and hygiene requirements (19 per cent). Ten days after the earthquake, basic environmental health needs of food, shelter and hygiene still predominated in this displaced population. Significant portions may have special needs due to age or illness.     

The impact of local elites on disaster preparedness planning: the location of flood shelters in northern bangladesh

Disaster relief and preparedness organisations are concerned with allocating scarce resources in unstable environments, such as those prone to flooding and river erosion. The need to understand the role of powerful elites in such disaster prone environments is illustrated through an analysis of the actual location decisions and biases involved in siting four flood shelters in four communities in northern Bangladesh. The previously unrecognised implications of the location biases for employment, shelter, access and the utilisation of the flood shelter by the powerless people in the target group demonstrate the need for disaster organisations to include an analysis of the local power structure in project preparation and appraisal.     

A cluster-based decision support system for estimating earthquake damage and casualties

This paper describes a Decision Support System for Disaster Management (DSS-DM) to aid operational and strategic planning and policy-making for disaster mitigation and preparedness in a less-developed infrastructural context. Such contexts require a more flexible and robust system for fast prediction of damage and losses. The proposed system is specifically designed for earthquake scenarios, estimating the extent of human losses and injuries, as well as the need for temporary shelters. The DSS-DM uses a scenario approach to calculate the aforementioned parameters at the district and sub-district level at different earthquake intensities. The following system modules have been created: clusters (buildings) with respect to use; buildings with respect to construction typology; and estimations of damage to clusters, human losses and injuries, and the need for shelters. The paper not only examines the components of the DSS-DM, but also looks at its application in Besiktas municipality in the city of Istanbul, Turkey.

Modelling the elements of country vulnerability to earthquake disasters

Earthquakes have probably been the most deadly form of natural disaster in the past century. Diversity of earthquake specifications in terms of magnitude, intensity and frequency at the semi-continental scale has initiated various kinds of disasters at a regional scale. Additionally, diverse characteristics of countries in terms of population size, disaster preparedness, economic strength and building construction development often causes an earthquake of a certain characteristic to have different impacts on the affected region. This research focuses on the appropriate criteria for identifying the severity of major earthquake disasters based on some key observed symptoms. Accordingly, the article presents a methodology for identification and relative quantification of severity of earthquake disasters. This has led to an earthquake disaster vulnerability model at the country scale. Data analysis based on this model suggested a quantitative, comparative and meaning full interpretation of the vulnerability of concerned countries, and successfully explained which countries are more vulnerable to major disasters.     

Health Assessment of the 1985 Flood Disaster in Puerto Rico

In Puerto Rico, during October 1985, tropical storm Isabel caused widespread flooding, landslides, and collapsing of bridges. A maximum of 180 persons died, including an estimated 127 at a landslide where the majority (78%) of deaths resulted from traumatic injury. Approximately 3,000 homes were damaged with 4,400 persons temporarily displaced into 44 shelters. A shelter surveillance system was established to monitor 19 acute and chronic conditions in 28 shelters during a 5-week period. Trend analysis trends of selected reportable communicable diseases in the general community revealed no changes attributable to the disaster in the 12 most severely affected municipalities. In these municipalities, the number of persons using the scheduled outpatient clinics after the disaster decreased significantly, but the mean daily number of emergency room visits did not show significant change. Analysis of surveillance data showed that no infectious disease outbreaks had occurred in the shelters. The post-impact health consequences resulting from this widespread flooding were minimal. Even so, disease surveillance remains essential for efficacious resource allocation and prevention strategies.
