采空区上覆火成岩断裂致灾机理研究

为了解释采空区影响下火成岩断裂破坏诱发地表裂缝的形成原因,通过建立两种采动影响下的火成岩断裂物理力学模型,推导出采动影响下火成岩初次断裂和周期性断裂判据。结合铁法晓南矿开采出现的地表裂缝,分析了火成岩断裂破坏机理,并对火成岩断裂破坏进行了预测。通过与现场实测地表裂缝位置加以验证,证明了所建力学模型的可靠性,并给出了后续生产中关于地表裂缝的规避性建议。     

甲型流感的流行与防控分析及其对新冠肺炎疫情的启示

目前新型冠状病毒肺炎（COVID-19）疫情在全球流行,对人类生命健康造成威胁.对甲型流感这一常见传染病进行流行特征、影响因素和防控措施分析,回顾总结全球为防控甲型流感做出的努力及相关科学研究成果,为新型冠状病毒肺炎疫情提供防控经验和研究思路.结果表明:①甲型流感呈季节性流行,受气候、社会、政治和文化等多因素影响,在低温低湿、人口密集的环境中表现出强流行性.②甲型流感防控研究工作主要包括季节性流感病毒监测、流感病毒的生态学研究、广谱中和抗体及通用疫苗的研究、应对流感大流行的病原学风险评估四方面,其中季节性流感病毒监测是制定公共卫生政策及后续研究的核心防控措施.③与甲型流感类似,新型冠状病毒肺炎疫情流行受温度等气候因素影响,同时社会、政治、文化等因素也影响其传播,亟需借鉴较成熟的甲型流感的防控经验、技术和平台.建议在加强病毒监测的同时,深入开展病毒生态学研究、病原学风险评估和药物开发,对完善疫情防控工作和预警预测未来可能出现的二次暴发及传播至关重要.研究结果将为新型冠状病毒肺炎疫情和未来传染病疫情的防控及预测预警提供参考和研究思路.      

COMPLIANCE WITH STORM WATER POLLUTION PREVENTION REGULATIONS BY THE METAL FINISHING INDUSTRY1

ABSTRACT: Federal and state storm water pollutant control regulations for industry require facilities to identify themselves and to implement appropriate controls specifically developed for each facility by its operators. Compliance is not directly observable from publicly reported information, and is believed to be low. Compliance requirements are divided into three stages: determination and notification of duty to comply; preparation of public reports and site-specific planning documents; and implementation of pollution prevention activities. Aggregate data show about 25 percent to 35 percent of metal plating facilities in California, and about 35 percent to 40 percent of facilities in the Los Angeles region, have recognized the need for first-stage compliance; the number required but failing to do so is not known. For second-stage compliance, between 77 percent and 88 percent of facilities submitted required annual reports from 1993 to 1995, while on-site water quality monitoring reports were submitted by about 60 percent of required facilities. Site investigations of ten Los Angeles area facilities showed variation in compliance with site-specific documentation and implementation requirements. Most facilities inadequately evaluated activities for potential storm water pollutants, and most prepared incomplete plans for storm water sampling and inspection procedures. Evaluation of third-stage compliance by evaluating quantitative effects of facility actions, beyond the scope of this research, is recommended.     

GIS在震后应急反应中的应用

震后应急反应是减轻震害的关键措施之一。震后应急的基础在于信息的收集和处理。ＧＩＳ（地理信息系统）具有很强的信息管理能力和空间数据处理、分析能力。借助于这个系统,可以解决以往应急反应中存在的资料分散、资料更新慢、管理费用大以及大量信息难以提取、查询和使用等问题。ＧＩＳ与震后应急反应的结合可以大大提高应急反应的速度和准确性。     

农村森林防火存在"五缺"、亟待"十改"

经实地调查发现,农村森林防火工作中存在"不管、不扑、不报、不查、不恢复"五个现象,其原因主要在于农村森林防火存在"五缺",即缺人管、缺钱管、缺健全的法制、缺责任制的真实约束和缺激励机制,缺先进扑火设备.由此笔者认为农村森林防火亟待"十改",即,改"五长负责制"为"各级党政一把手负责制"、改"防盗为主"为"防火为主"、改"入海战术"为"精兵上阵"、改"死拼硬打"为"确保生命安全为前提的灵活战术"等等.     

A GIS-based vulnerability assessment of coastal natural hazards,state of Pará, Brazil

Studies carried out in the NE coastal zone of the State of Pará (Brazil) have recorded, in the last 25 years, numerous evidence of natural impacts of the flood and erosion processes. As a consequence, diverse strategies and measures of population adaptation have been implemented but with limited success. Therefore, in order to subsidize the Coastal Zone Management Program of Pará, this paper aims to identify, assess and classify natural and socio-economic vulnerabilities of this coastal zone by means of a Geographical Information Systems (GIS)-based composite coastal vulnerability index (CVI). In spite of the data problems and shortcomings, using ESRI’s Arcview 3.2 program, the CVI score, to classify, weight and combine a number of 16 separate natural and socio-economic variables to create a single indicator provides a reliable measure of differences (5 classes) among regions and communities that are exposed to similar ranges of hazards. The results are presented in three maps referred to as Natural, Socioeconomic and Total Vulnerability. The confidence associated with the results obtained, the need to utilize another variables, and to frequently update the ones used already were analyzed and discussed.
