川藏铁路四川段沿线诱发地质灾害降水阈值研究

利用2009—2019年川藏铁路沿线四川段地质灾害数据、国家气象中心逐小时降水量资料,统计了地质灾害与降水的关系,发现研究区89%的滑坡灾害和96.6%的泥石流均发生在汛期,且地质灾害高发路段位于青衣江暴雨区,与四川地区降水时空分布特征相吻合。分析雨型、降雨强度、前期降雨等因子对地质灾害的影响,发现快速激发,中速激发和慢速激发的地质灾害分别约占33.3%、25.9%、40.8%,表明降雨历时并不是影响地质灾害发生的最直接因子,前期降雨的作用不可忽视;结合环境因子对地质灾害进行了分区,基于降雨历时-雨强(I-D)预报模型建立了川藏铁路沿线四川段引发地质灾害的降水阈值分布。利用该降水阈值的分布特征,检验了2019年引发地质灾害的降水量,发现阈值雨量的判别方法较为科学,具有较强的参考价值。     

我国旱涝空间型的马尔科夫概型分析

旱涝灾害在我国是影响最大、也最为频繁的气候灾害。本文利用马尔科夫概型分析的原理和方法，在验证了我国旱涝空间型序列具有马尔科夫性质的基础上，计算出各状态的转移概率，进而分析了旱涝空间型序列的静态和动态结构，并揭示出旱涝空间型各状态演化的优势倾向。     

政府部门的应急响应能力在城市防灾减灾中的作用

城市是人口、经济密集的地区,城市自身的特点决定了抢险救灾必须快速果断,当城市发生灾害时,当地政府部门是抢险救灾的主力军,在这一过程中,政府部门对灾害的应急反应能力成了救灾、减灾成功与否的决定性因素.文章探讨了政府部门的应急响应能力的组成及其在城市防灾减灾中的重要性.政府部门的灾害应急能力主要从应急反应、应急指挥、应急救援、应急信息的发布和应急避难五个方面体现出来.     

Establishing moral bearings: ethics and expatriate health care professionals in humanitarian work

Expatriate health care professionals frequently participate in international responses to natural disasters and humanitarian emergencies. This field of practice presents important clinical, logistical and ethical challenges for clinicians. This paper considers the ethics of health care practice in humanitarian contexts. It examines features that contribute to forming the moral landscape of humanitarian work, and discusses normative guidelines and approaches that are relevant for this work. These tools and frameworks provide important ethics resources for humanitarian settings. Finally, it elaborates a set of questions that can aid health care professionals as they analyse ethical issues that they experience in the field. The proposed process can assist clinicians as they seek to establish their moral bearings in situations of ethical complexity and uncertainty. Identifying and developing ethics resources and vocabulary for clinical practice in humanitarian work will help health care professionals provide ethically sound care to patients and communities.     

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。     

灾害保险在灾害防御中的作用：以江苏省自然灾害为例

本文以江苏省的自然灾害为例,阐述了灾害保险在减轻自然灾害损失中的作用,提出在经济发达地区,灾害保险应作为灾害防御对策中的重要方面。     

爆炸灾害的预防和控制乃当务之急

我国爆炸事故近年来屡屡发生，灾害严重，损失巨大。爆炸灾害的预防与控制己是当务之急。当前的主要研究内容，有各种工业粉尘爆炸、气液贮罐爆炸、工业生产中的静电灾害、各种爆炸灾害的实验观测和监控技术、防护与控制技术、模拟与仿真技术、易燃易爆物的危险性评估和系统安全性分析、燃烧转爆炸机理和热爆炸（热自燃）机理等方面。简略介绍了爆炸灾害预防、控制国家重点实验室的筹建工作，希望得到同行专家的指导和帮助，并开展合作研究。     

The environmental dimension of national security: A test of systems analysis methods

The systems approach permits us to analyze national security as a cluster of interconnected elements, in which the environmental dimension appears to be the most important one. The environmental problem is divided into two main aspects: environmental security per se and the impact of environment on the overall status of a nation's security. It is argued here that the quality of life and health serve as both the main objective and the principal criterion of environmental security in a social system. Indices of these two factors are used in this article as indicators of the state of this type of security. They confirm that vast areas of Russia, the Ukraine, and Central Asia (especially the Aral Sea region) should be considered as presenting a substantial risk to local people and even producing global impacts on both natural and man-made systems. Environmental factors that destabilize national security are also divided into two groups: those that impact social systems directly and negatively (mainly natural disasters) and technological and sociopolitical agents that cause indirect impacts, in both war and peace time, as well as in the civil and military sectors of the economy. Developments in the former Soviet Union (the Commonwealth of Independent States) are used as an illustration of the consequences that such impacts may have on the status of national security.
