Residents' preparedness and response to the Kalamazoo Tornado

A survey was conducted of individuals residing directly in the path of the tornado that hit Kalamazoo, Michigan, on 13th May 1980. The residents' tornado preparedness and response were examined in an effort to evaluate the city's emergency warning system. The system was adequate for people on the east side of the city and lacking for west side residents. Other factors pertaining to the storm event and human response were also evaluated.     

用伴随方法对毒气泄漏事件进行危害评估

由于自然、人为等因素造成的有毒气体泄漏事件随时威胁着人们的生命安全。对于这类突发事故进行危害评估 ,在应急救援中 ,可以给决策者提供参考 ,使之采取有效措施 ,最大限度地降低事故危害程度 ,减少事故恶果及引起的恐慌。由于毒气泄漏位置事先无法确定 ,如果用常规方法进行逐点评估 ,将面临着巨大的计算量而难以进行。笔者发展了一种伴随方法 ,对风险函数的表达式进行等价变形 ,通过求解伴随方程 ,可以一次求得任意位置的毒气泄漏的风险值 ,大大降低计算量和工作量。此法在化学工厂和仓库设置 ,煤气网铺设和监测点选取 ,城市应急中心设置等多种安全规划中均有重要价值 ,为快速危害评估 ,降低化学事故危害提供了有力的研究工具和实用方法。     

Mine closure legislation in Indonesia: The role of mineral industry involvement

Major mining companies have recently embraced the sustainable development paradigm, in seeking to improve their competitiveness and increase shareholder returns. Successful mine closure is one important element of this process. Improved performance in this area is essential if surrounding communities are to see mining companies as responsible corporate and social partners.
In Indonesia, the new approach has coincided with the development of specific mine closure legislation. To facilitate the legislation, a consortium of mining companies joined to form the Industry Mine Closure Steering Committee. This Committee has lobbied the Government, actively negotiating to incorporate sustainable development ideals and practices into the new legislation. The Committee's aim has been to foster continued development of the mining industry, while taking account of variation in environmental, social and community conditions. In describing the process, this article seeks to provide guidance for the development of mine closure legislation in other nations.     

2002年我国事故与灾害状况综述

Characterisation of Organic Matter and Carbon Cycling in Rehabilitated Lignite-rich Mine Soils

Open-cast lignite mining in the Lusatian mining district resulted in rehabilitated mine soils containing up to four organic matter types: (1) recent plant litter, (2) lignite deposited by mining activity, (3) carbonaceous ash particles deposited during amelioration of the lignite-containing parent substrate and (4) airborne carbonaceous particles deposited during contamination. The influence of lignite-derived carbon types on the organic matter development and their role in the soil carbon cycle was unknown. This paper presents the findings obtained during a six year project concerning the impact of lignite on soil organic matter composition and the biogeochemical functioning of the ecosystem. The organic matter development after rehabilitation was followed in a chronosequence of rehabilitated mine soils afforested in 1966, 1981 and 1987. A differentiation of the organic matter types and an evaluation of their role within the ecosystem was achieved by the use of ¹⁴C activity measurements, ¹³C CPMAS NMR spectroscopy and wet chemical analysis of plant litter compounds. The results showed that the amount and degree of decomposition of the recent organic matter derived from plant material of the 30 year old mine soil was similar to natural uncontaminated forest soil which suggests complete rehabilitation of the ecosystem. The decomposition and humification processes were not influenced by the presence of lignite. On the other hand it was shown that lignite, which was thought to be recalcitrant because of its chemical structure, was part of the carbon cycle in these soils. This demonstrates the need to elucidate further the stabilisation mechanisms of organic matter in soils.     

基于多媒体技术的<中国自然灾害>教育软件开发

根据社会公众对中国自然灾害信息的需求，开发了《中国自然灾害》多媒体教育软件。软件以区域灾害系统理论为指导，设计了内容框架、基本体系。通过声音、影像、动画和文本等媒体形式可向社会深层次、多角度地介绍中国自然灾害信息，普及减灾知识，增强社会防灾减灾意识。     

灾害旅游资源探讨

灾害经济学中的害利互变原理表明，灾害也有“利”的一面。它在给人类造成巨大损失的同时，也塑造了奇异独特的灾害旅游资源，其开发利用效用是其他旅游资源无法代替的。本文系统阐述了灾害旅游资源的基本属性、特性、类型及可持续开发利用的设想，以便使灾害旅游资源可以发挥更大的社会和经济效益。     

中国灾害的军事救援及其机制研究

中国是一个灾害频繁的国家。灾害造成了巨大的直接、间接经济损失和人员伤亡，对社会经济发展产生了严重的影响。中国的具体国情和人民解放军的特殊性质，决定了军事救援历来在中国的灾害救援中具有不可替代的地位，发挥着突击队和生力军的作用。由于客观上存在着一些制约因素，使得军事救援的实施效率受到了一定程度的影响，未能得到最大限度的发挥。因此，必须尽快建立适应新时期军队执行抢险救灾任务需要的军事救援机制。     

四川省泥石流灾害保险的风险分析与区划

泥石流灾害保险的风险评估和区划，是分区分类防灾和损失评估的重要依据，也是泥石流灾害保险费率厘定的基础。采用综合评判的数学方法，选取对泥石流灾害保险起主导作用的灾害损失、孕灾环境和风险区价值为评判因子，对泥石流灾害保险的风险进行了评估。以四川省为例，介绍了进行风险区划的方法和步骤，将四川全省按地、市、州级行政区划分为19个风险评判区，对各区进行泥石流灾害保险风险评估，在此基础上完成了四川省泥石流灾害保险风险评估区划图。
