泥沙灾害和泥沙环境快速评估方法研究

泥沙灾害可以看作是泥沙环境突变或渐变积累到一定条件下发生变异时的表现形式,各类泥沙灾害和泥沙环境都具有不同的内涵和表现方面, 因此泥沙灾害和泥沙环境的评估应具有不同的对象。一旦研究的对象被确定,泥沙灾害的表现因子组合便可明确。类似地泥沙环境的环境变量和总体状况的指示怀变量也可确定。为了便于了解泥沙灾害和泥沙环境的关系,并提高评估效率,可将泥沙灾害和泥沙环境快速评估的参照组建立在能够包括影响二者表现特征的诸环境变量的最小图斑上,通过选取适当参照点,分类确定不同参照组,利用待评估地点孕灾环境因子（或环境变量）与不同参照组的相似分析。预测评估点的泥沙灾害和泥沙环境表现因子特征和动态过程.     

Post-traumatic stress disorder and comorbid depression among survivors of the 1999 earthquake in Turkey

This study examined the prevalence of post-traumatic stress disorder (PTSD) and comorbid depression some three years after the August 1999 earthquake in Turkey among a sample of 769 survivors relocated to a permanent housing site built for homeless survivors in the epicentre region. Time since trauma was 3.1 years for 81 per cent of the participants and 3.9 years for the remainder. Survivors were assessed using the Screening Instrument for Traumatic Stress in Earthquake Survivors, an easily administered self-rating scale with demonstrated validity. The estimated rates of PTSD and comorbid depression were 40 per cent and 18 per cent, respectively. Linear regression analyses showed that PTSD strongly related to fear during the earthquake, while depression related to loss of family members. These results suggest that catastrophic earthquakes have long-term psychological consequences and highlight the need for a cost-effective mental health care model for earthquake survivors.

我国近年农业气象与农业生物灾害的特点

以1999,2000,2003,2004,2005,2006和2007年各省份(包括直辖市、自治区,下同)单位播种面积的成灾面积比例与全国的均值相比较,计算了各省这7年中各灾害的成灾指数。结果表明:(1)全国有12个省份的旱灾情况重于全国平均水平,其中内蒙古、甘肃、辽宁旱灾最为严重,成灾指数在2.5以上。(2)有10个省份洪涝灾重于全国平均水平,洪涝灾严重的4个省份依次是湖北、重庆、安徽、湖南。(3)有8个省份风雹灾情况重于全国平均水平,灾害严重的依次是浙江、北京、海南、青海、河北。(4)有7个省份台风灾情况重于全国平均水平,5个灾害严重的省份依次是浙江、海南、广东、福建、广西。(5)有6个省份低温冻害情况重于全国平均水平,5个严重省份依次是宁夏、青海、甘肃、内蒙古和湖北。(6)有10个省份农作物病虫害受灾情况重于全国平均水平,4个严重的省份依次是上海、江苏、浙江、河北。(7)有16个省份农田草害情况重于全国平均水平,农田草害严重的6个省份依次是山东、湖南、江苏、河北、北京、浙江。(8)有15个省份农田鼠害情况重于全国平均水平,其中4个省份为重灾,依次是北京、吉林、青海、重庆。北京历年受灾最为严重,成灾指数平均在3.4以上。因此,我国各种自然灾害的主要分布地区和省份变化较大,各地区和省份应根据当地发生的主要灾害,采取有针对性的防治对策。     

Supporting breastfeeding in emergencies: protecting women's reproductive rights and maternal and infant health

Women have the right to support that enables them to breastfeed. Supporting breastfeeding in emergencies is important because artificial feeding places mothers and children at risk. In emergencies, artificial feeding is dangerous to the infant, difficult and requires substantial resources. In contrast, breastfeeding guards infant health. It is also protective against postpartum haemorrhage, maternal depletion, maternal anaemia and closely spaced births and should therefore concern not only nutritionists, but also those involved in reproductive health. However, it is common for women's ability to breastfeed to be undermined in emergencies by the indiscriminate distribution of breast-milk substitutes and the absence of breastfeeding support. Controlling the distribution of breast-milk substitutes, providing supportive environments, and appropriate medical and practical assistance to breastfeeding women safeguards the health and well-being of mothers and babies. Greater collaboration between the nutrition and reproductive health sectors is required to promote best practice in protecting breastfeeding women and their children in emergencies.     

天津市自然灾害特征及防治对策

Connectedness, social support and internalising emotional and behavioural problems in adolescents displaced by the Chechen conflict

The study investigated factors associated with internalising emotional and behavioural problems among adolescents displaced during the most recent Chechen conflict. A cross-sectional survey (N=183) examined relationships between social support and connectedness with family, peers and community in relation to internalising problems. Levels of internalising were higher in displaced Chechen youth compared to published norms among non-referred youth in the United States and among Russian children not affected by conflict. Girls demonstrated higher problem scores compared to boys. Significant inverse correlations were observed between family, peer and community connectedness and internalising problems. In multivariate analyses, family connectedness was indicated as a significant predictor of internalising problems, independent of age, gender, housing status and other forms of support evaluated. Sub-analyses by gender indicated stronger protective relationships between family connectedness and internalising problems in boys. Results indicate that family connectedness is an important protective factor requiring further exploration by gender in war-affected adolescents.     

我国主要农业气象灾害机理与监测研究进展

对我国农业气象灾害机理与监测方面的研究进行了深入系统的回顾与评述,阐述了我国主要农业灾害研究的前沿领域和学术问题,探讨了农业灾害研究的发展趋势.灾害性天气只是农业成灾的外部环境条件(环境胁迫),在这种环境胁迫下,农业生产系统是否最终成灾,还要取决于农业生产系统本身对这种环境胁迫的应对和作用.因此农业灾害机理反映了环境胁迫与农业生产系统的相互作用和相互影响.当前,对农业灾害机理研究不足,农业成灾过程和关键因子认识不深入,农业灾害监测理论与方法不完善,已经成为建立有效的农业灾害监测预警系统、开展灾害时空动态监测,以及国家进行重大防灾减灾决策的瓶颈和障碍.对主要农业灾害机理开展研究以及发展农业灾害理论和监测方法,是国家实现农业发展目标的需要,也是多门相关学科理论与方法发展的需要.     

两宋时期自然灾害的文学记述与地理分布规律

两宋320年间共发生灾害1739次,灾害种类14种,如此深重的灾害是导致两宋"积贫积弱,国力不强"的一大主要因素.由于宋朝时期的地理气候特点,水灾、旱灾接连不断发生,并且成为两宋最主要的自然灾害.古代自然灾害研究主要依据史书记载,中国是世界上少数灾害多发的国家之一,文学作品中反映出来的灾难与救世观念可以给人们很多启发.以王禹偁为代表的宋代文学家给后世留下了许多记述灾害的文学作品,从文学作品的记述中可以提取古代灾害的准确信息.北宋都城位于开封,南宋京都在杭州,由于史料对当时中央政府所在地省份的记述颇为翔实,两宋自然灾害的省区分布,以河南、浙江灾害次数最多.

我国海岸带灾害成因分析及减灾对策

近年来海岸带灾害越来越成为制约海岸带－我国最重要的经济带社会、经济和环境可持续发展的重要因素。本文在全球变化和人类活动影响的背景下,分析探讨了我国海岸带灾害的基本成因,并提出了相应的概念性减灾对策框架,海岸带生态环境的脆弱性,全球变化（相对海平面变化、气候异常）和人类活动是导致我国海岸带灾害的3个主要方面。据此,认为减灾的关键在于合理规范人类行为,保护和改善本已十分脆弱的海岸带生态环境,使人与自然界和谐相处;对于全球变化诱发的灾害,则力求基于科学认识与预测,在海岸带开发中合理规划建设,做到未雨绸缪,实现海岸带社会经济可持续发展。     

河南小麦生产农业气象灾害风险分析及区划

根据农业气象灾害风险分析理论，以河南省小麦生产为例，在辨识对小麦产量影响较大的农业气象灾害风险要素和风险源的基础上，通过构造灾度函数，运用EOF和概率等分析方法，分析了河南省小麦生产中的3种主要农业气象灾害——麦播旱涝、晚霜冻、干热风与青枯雨的发生规律及其对小麦产量的定量影响程度与风险概率。在此基础上，运用多因子综合风险指数模型，对河南省小麦生产农业气象灾害风险进行了综合区划，为农业气象灾害风险探讨了一条新的定量分析及区划技术体系。分析发现，干热风与青枯雨是影响河南省大部分地区小麦高产稳产的主要灾害，其次是晚霜冻危害，第三是麦播时旱涝灾害，但总体上河南省小麦生产的农业气象灾害风险并不算太高，只要采取一定的防御措施，不会在根本上影响小麦的高产稳产。     

新疆1950～1997年洪旱灾害的统计与分形特征分析

基于新疆1950～1997年的洪旱灾害统计资料,运用一般统计学方法与分形理论分析了新疆这段时期内相应的洪旱灾害特征。分析发现,20世纪80代年以来新疆洪旱灾害呈急剧扩大的态势,20世纪80年代和90年代与50年代相比,洪水与干旱灾害成灾面积都增大了约6～7倍;1950～1997年新疆洪旱灾害时间序列具有明显的分形特征,相应的饱和分维数分别为d=2.9733与d=3.6921,饱和关联维数对应的嵌入空间的最小维数为9。     

Children and the Sphere standard on mental and social aspects of health

Most of the world's children live in resource-poor countries where people are at a relatively high risk of exposure to catastrophic situations arising from conflict and natural disasters.(6) Given the potential social, psychological and psychiatric consequences of exposure to disaster, mental health and psychosocial support programmes are increasingly part of humanitarian aid. A minimum standard on mental and social aspects of health is included in the recently revised Humanitarian Charter and Minimum Standards in Disaster Response (Sphere Handbook) (Sphere Project, 2004). Most recommendations for mental health and psychosocial interventions in guidance documents are based on expert opinion rather than research. Consequently, interventions are being implemented without full understanding of their potential benefit or harm. This paper offers a child-focused review of the evidence for each of the interventions described as indicators for the Sphere standard on mental and social aspects of health. It suggests some, but limited, support for each of them. However, the evidence base needs substantial strengthening.     

30年来我国农业气象灾害变化趋势和分布特征

The influence of caste,class and gender in surviving multiple disasters: A case study from Orissa,India

Sociological and anthropological studies in India reveal that caste, class and gender in everyday life are both rigid and dynamic, but little is known about how they influence the survival mechanisms of women during ‘multiple disasters’, nor about how women negotiate with these structural mores to meet their cultural and biological needs. This is explored through the experiences of 12 women-headed households from different social castes in Orissa, India. Multiple disasters or disasters that occur in ‘one specific place’ (such as floods, cyclone and drought) are regular events in coastal parts of the state of Orissa. The super-cyclone of 1999, two floods of 2001 and 2003 and drought of 2000 and 2002 form the case study. Participant observation, in-depth interviews and documentary evidence complement the fieldwork. The findings suggest a complex interplay of caste, class and gender in surviving the multiple disasters including structural mutability under the purview of social organization. In doing so, women demonstrated their individual and collective agencies in order to meet their cultural and biological needs under severe crisis. This research stresses that gender and disaster studies must include a consideration of caste and class for effective disaster management and social vulnerability reduction.
