2011年1-7月国内外石油与化工事故分析

基于2011年1-7月国内外石油与化工事故,从事故发生时间、经营类型和事故类型等方面进行了分析,并分析了重大自然灾害的影响。结果表明：7月是事故高发的月份,化工生产事故最多,泄漏是主要的事故类型;日本地震等重大自然灾害对石油与化工行业产生很大的影响。从推进中小化工企业的安全标准化工作、加强储存运输的安全运营保障、提高企业应对自然灾害的能力等方面提出了建议,以预防或减少事故发生。     

湖南省山洪灾害经济损失评价

山洪灾害是湖南省山丘区经济可持续发展的重要制约因素。文章采用山洪灾害经济损失的不稳定度Us和灾害直接经济损失占应得GDP百分比的平均数Cr,构建了湖南省山丘区山洪灾害灾损度指数DELI。研究表明,Us高值区和Cr高值区在空间上明显错位,前者为湘西自治州、怀化、张家界、郴州等,后者是张家界、娄底、邵阳等。根据DELI等级...

昆仑山木孜塔格峰北坡藏羚繁殖地的自然植被

通过对阿尔金山国家级自然保护区内藏羚产羔繁殖期的野外考察,研究了昆仑山木孜塔峰北坡藏羚繁殖地的自然植被及其分布,从繁殖地的自然生态特征按摩了藏羚与其繁殖期栖息生之间的关系。结果表明,藏羚对产羔繁殖地的选择不是基于植被条件,而是选择更加安全的区域作为其产羔繁殖地。     

ROLE OF EROSION PROCESSES IN TRANSFER OF RADIONUCLIDES: RESULTS OF FIELD EXPERIMENTS1

ABSTRACT: An experimental one-year fieldwork has been conducted in the vicinity of the Chernobyl NPP, within an agricultural watershed, to study the transfer of radionuclides brought into the environment by the disaster of 1986. Presented are results of observation of the washout of ¹³⁷Cs from the runoff plot both in natural conditions and under artificial rainfalls. Beside traditional hydro-logical methods, new techniques were used allowing to consider microtopographical peculiarities of the runoff plot and their role in the redistribution of radionuclides. The estimate of the annual mass balance for the soil and the radionuclides within the runoff plot has shown that, regardless of significant areal variation of their concentration, the ¹³⁷Cs washout with the solid runoff resulted from artificial rainfalls amounts to some 1 percent of its reserves in the uppermost 5 cm of the topsoil. The same parameter for the natural runoff is lower by an order of magnitude. Both these factors of self-purification are about two times less than natural radioactive decay of ¹³⁷Cs.     

大同—阳高地震灾害评估及灾因分析

本文记述了大同—阳高地震震害情况,同时对造成灾害的原因进行了分析,认为此次地震震级不大而损失严重的主要原因除了与地震持点和发震构造有关之外,还与当地民舍抗震性能差、施工质量低有直接关系。     

Public participation in NGO-oriented communities for disaster prevention and mitigation (N-CDPM) in the Longmen Shan fault area during the Wenchuan and Lushan earthquake periods

ABSTRACT

The Longmen Shan fault area in southwest China is one of the world’s most active earthquake zones. The epicenters of the two most recent earthquakes, the 2008 Wenchuan earthquake (8.0?Ms) and the 2013 Lushan earthquake (7.0?Ms), both of which caused serious losses, were only 85?km apart. Community-based disaster risk reduction is the foundation of the disaster management system pyramid and is critical to the success of ‘sustainable hazard mitigation’. Based on multiple collaborative stakeholder perspectives, this paper examines public participation in an NGO-oriented Community for Disaster Prevention and Mitigation (N-CDPM) in the period between the two earthquakes as a multi-stage problem; N-CDPM establishment, normal operations, disaster testing, and continuous improvement. Multi-stage field research was conducted in the affected areas in the Longmen Shan fault area to examine the collaboration in each stage, after which the differences were compared across the four stages based on eight key indices; scales, core stakeholders, core network stability, mean number of lines, mean collaborative level, governments, and individual and public organization participation. The government participation, individual participation, and public organization participation are then discussed. This paper provides a novel research approach to CDPM in multiple earthquake regions and gives rich insights into the collaboration between the government and the public for N-CDPM.     

河北省自然灾害危险性分析及其在主体功能区划评价中的应用

自然灾害危险性是主体功能区划评判的基础指标之一,用于反映特定区域自然灾害发生的可能性和灾害损失的严重性,是评价区域开发支撑条件的一个重要指标。在分析自然灾害危险性指标评价方法、流程及其在主体功能区划评价中的作用的基础上,依据河北省的自然环境特点及主要自然灾害情况,选取其主要灾害要素为评价对象,利用G IS技术对河北省自然灾害危险性进行了综合分析,并在此基础上综合评价了河北省自然灾害对区域发展的影响。
