鹤岗煤矿开采诱发地震研究

对鹤岗煤矿开采诱发地震的生成环境、活动与破坏特征及震源机制进行了分析，提出鹤岗矿震的孕育和发生受到人为采掘因素和区内构造应力场的双重作用。在特定的构造物理条件和地球动力学环境下，深部采矿使井下断裂构造从稳定状态逐渐活动或蠕动，致使局部活化。矿震具有震源浅、对地表破坏强的特点。震源机制表现出断层的运动方式有走滑断层，也有正断层和逆断层。

The feasibility of concentrated rural settlement in a context of post‐disaster reconstruction: a study of China

There is growing appreciation of the use of concentrated rural settlement as an effective means of implementing infrastructure projects and helping to achieve sustainable development in rural areas. This occurs in China through the exchange of rural residential land for urban construction. However, this policy has not been effective under normal circumstances (called development‐driven conditions) as frequently farmers are reluctant to accept such an exchange. By contrast, in a time of disaster, such as after the 2008 earthquake in Sichuan Province, China, rural victims have accepted this policy of rural residential land exchange. Employing game theory, this paper identifies the reasons for the different outcomes and it contends that the implementation of concentrated rural settlement practice under disaster‐induced conditions is more effective than its introduction under development‐driven conditions. The results of the analysis indicate that, in China, concentrated rural settlement is feasible in a context of post‐disaster reconstruction.     

Classification of residential areas according to physical vulnerability to natural hazards: a case study of Çanakkale,Turkey

The selection of new settlement areas and the construction of safe buildings, as well as rendering built‐up areas safe, are of great importance in mitigating the damage caused by natural disasters. Most cities in Turkey are unprepared for natural hazards. In this paper, Çanakkale, located in a first‐degree seismic zone and sprawled around the Sartçay Delta, is examined in terms of its physical vulnerability to natural hazards. Residential areas are analysed using GIS (geographic information system) and remote‐sensing technologies in relation to selected indicators. Residential areas of the city are divided into zones according to an evaluation of geological characteristics, the built‐up area's features, and urban infrastructure, and four risk zones are determined. The results of the analysis show that the areas of the city suitable for housing are very limited. In addition, the historical centre and the housing areas near Sartçay stream are shown to be most problematic in terms of natural disasters and sustainability.     

我国冬小麦霜冻灾害致灾因子危险度评价——基于作物生育阶段气象指标

霜冻是一种威胁农业生产的气象灾害,对其致灾因子危险度的研究,可为大尺度的作物霜冻灾害区划及农业保险提供依据。根据作物生长发育的阶段性原理,以全国751个气象台站56年的逐日最低气温资料以及作物生育期资料为基础,统计得到冬小麦各个生育阶段不同灾害等级（轻霜冻、中霜冻、重霜冻）的年霜冻日数,并计算出冬小麦全生育期内不同等级霜冻的发生概率,基于以上两项指标对冬小麦霜冻致灾因子危险度做出评价。结果表明,研究期内重霜冻年霜日最大值为129d,而轻霜冻和中霜冻霜日最大值分别为23 d和19 d,冬小麦受重霜冻危害时间较长;冬小麦霜冻的频发区、多发区、少发区从北向南依次分布,随着霜冻等级增加,频发区的面积差异不大,但多发区的面积减小、少发区面积增大;冬小麦霜冻灾害危险度等级最低的地区主要分布在低纬度的几个省份,如海南、广东、广西、云南等,危险度等级最高的地区集中在青藏高原地区。     

天津市滨海新区地震地质灾害评价与分区研究

收集了天津市滨海新区大量的工程地质勘察资料,针对滨海新区场地工程地质条件,从地震地质背景、历史震害的影响出发,依照相应规范和地质类比等方法,通过滨海新区活动断层影响、砂土液化、软土震陷的评判,探讨了滨海新区在未来强震作用下可能出现的地震地质灾害类型及空间分布特征。     

自然灾害灾后重建技术及实践的研究进展

灾后重建是在灾害体发生之时及发生之后,采取应急救援、灾害管理,以及灾后评估、救助、规划等一系列过程,是一个典型的系统工程,可划分为前期应急重建、中期恢复重建及后期发展重建3部分。以自然灾害为主要研究对象,在分析中外关于灾后重建文献的基础之上,归纳了灾后重建的系统特征,介绍了灾后重建技术和实践的研究进展。灾后重建技术包括灾害分类分级、应急救援、灾后评估、灾害管理和重建规划5个方面,灾后重建实践研究分为地震、飓风、洪水和海啸4个方面,并对中外的灾后重建研究发展进行了展望。

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.     

2000-2007年省级区域自然灾害灾情分析

自然灾害是严重影响人民正常生产生活、国家经济持续发展的突发公共事件。区域自然灾害评估对于做好防灾减灾工作有着重要的意义。对区域灾情进行了综合评估,归纳总结了区域灾情分布规律。选择受灾人口、死亡人口、紧急转移安置人口、农作物受灾面积、农作物绝收面积、倒塌房屋、损坏房屋和直接经济损失等8个基本指标参与区域灾情评估,并利用灾情综合指数法构建了灾情指数,其中绝对指数反映了区域灾情的绝对强度,相对指数反映了区域灾情对当地社会经济的影响程度。用灾情指数综合评估了我国东、中、西部三大地带以及省级区域的灾情强度和空间分布规律,认为西部区域受灾程度最大,自然灾害对其的影响程度最深,其次是中部地区和东部地区;文章利用综合灾情的绝对指数和相对指数的对应关系,将我国大陆地区的31个省级单元划分为4类地区,即灾情总量较大且对本地影响较大、灾情总量较大但对本地影响较小、灾情总量较小但对本地影响较大以及灾情总量较小且对本地影响较小等4种类型。文章给出的灾情区域分布规律符合灾害系统理论,特别反映了承灾体的暴露度、脆弱性和抗灾能力是区域灾情强度的决定因素。评估结果与区域实际情况相符,说明所给出的灾情指数评估法是评估区域灾情强弱的合理有效方法。
