浅谈环境应急监测质量管理体系的建设

环境应急监测作为环境应急处置的基础环节,发挥着重要的决策支持和技术保障作用。本文主要论述了各级环境监测部门如何从组织体系、网络体系、信息体系、质量控制体系和评估及预测体系5个方面建立一套完善的环境应急监测质量管理体系,以确保环境应急监测的质量,为环境管理提供可靠的技术支持。     

不良的安全管理绩效对企业经营成本的影响研究

本文从多个方面探讨了企业的安全管理绩效与企业经营成本之间的关系,认为不良的安全管理绩效不仅会增加企业的人力资源成本,导致企业在工伤保险和商业保险上费用的增加,而且还将会产生更多的政府监管成本,以及现实中直接和间接的物质损失。可见,不良的安全管理绩效将会显著增加企业的经营成本。     

高等学校危险化学品安全管理模式研究

在分析我国与危险化学品安全管理相关的法律法规及国家标准体系的基础上,对高校危险化学品安全管理模式进行了研究,构建了高校危险化学品的组织管理体系,包括仓储、领取、使用、废弃安全管理模式和应急救援预案,以期为推进高校危险化学品安全管理工作建言献策。     

基于组织因素的航空安全评价与分析

基于组织因素,从事故类型出发寻找影响航空安全的因素,并采用层次分析法进行评价,得出各个指标因素的权重,确定机组、天气、公司管理是事故链中居于前3位的因素.对机组提出采用"PACE进谏法"和建立人为失误数据库进行训练等建议;针对天气提出改进气象装备,尽早预测并采取措施等建议;对公司管理提出借鉴瑞典航空公司的事前评估、自愿报告免责制度以及安全旁听制度等建议.     

人群密度对人群拥挤事故的影响

为了研究公共场所的人群密度与拥挤事故的发生概率.基于连续人群流动模型,从人群密度角度探讨了人群拥挤事故发生的机理.由于不同民族个体生理尺寸的差异,人群最大忍受密度不同,以此作为判断人群拥挤事故的标准,并结合我国情况提出我国人群最大忍受密度为9人/m2.最后模拟了某个拥挤事故场景,用该模型对其进行拥挤事故分析.结果表明,连续人群流动模型可以用于预测拥挤事故的发生,对预防和控制人群拥挤事故具有一定的指导意义.     

Assessing field vulnerability to phosphorus loss in Beijing agricultural area using Revised Field Phosphorus Ranking Scheme

Guanting Reservoir,one of the drinking water supply sources of Beijing,suffers from water eutrophication.It is mainly supplied by Guishui River.Thus,to investigate the reasons of phosphorus(P)loss and improve the P management strategies in Guishui River watershed are important for the safety of drinking water in this region.In this study,a Revised Field P Ranking Scheme(PRS)was developed to reflect the field vulnerability of P loss at the field scale based on the Field PRS.In this new scheme,six factors are included, and each one was assigned a relative weight and a determination method.The affecting factors were classified into transport factors and source factors,and,the standards of environmental quality on surface water and soil erosion classification and degradation of the China were used in this scheme.By the new scheme,thirty-four fields in the Guishui River were categorized as"low","medium"or"high"potential for P loss into the runoff.The results showed that the P loss risks of orchard and vegetable fields were higher than that of corn and soybean fields.The source factors were the main factors to affect P loss from the study area.In the study area,controlling P input and improving P usage efficiency are critical to decrease P loss.Based on the results,it was suggested that more attention should be paid on the fields of vegetable and orchard since they have extremely high usage rate of P and high soil test of E Compared with P surplus by field measurements,the Revised Field PRS was more suitable for reflecting the characteristics of fields,and had higher potential capacity to identify critical source areas of P loss than PRS.     

Examining adaptation and mitigation opportunities in the context of the integrated watershed management programme of the Government of India

India occupies 2.4% of the world’s geographical area with a large percentage of its land under agriculture. About 228 Million hectares (Mha) of its geographical area (nearly 69%) fall within the dryland (arid, semi-arid and dry sub-humid) region. Of the total cultivated area of 142 Mha, major part of agriculture in the country is rainfed, extending to over 97 Mha and constituting nearly 68% of the net cultivated area, therefore making the agricultural sector vulnerable and exposed to the vagaries of weather conditions. Climate change adds to this dimension of stress. A strong need is felt for targeting programmes in these areas that address issues related to employing suitable soil and water conservation measures. In this context this paper seeks to examine the case for watershed development as an adaptive strategy. An examination of the possibility of fortifying the existing programme with a view to adapting to expected changes in climate in future is undertaken. Also, the possibility of watershed development integrating into a suitable mitigation strategy for the country is assessed.

矿区可持续发展能力建设中生态环境管理研究

实现矿区的可持续发展有赖于发展模式的转变,转变传统的生态环境管理的基本观念,提出要完善和优化矿区的生态环境管理体制,建立矿区"环境-资源-经济"信息管理系统和生态环境综合分析决策模型,寓经济发展于环境管理中,寓环境管理建设于经济发展中,寓矿区发展于环境和经济的协调发展之中,推进矿区持续发展,为矿区环境保护和经济发展建立一个和谐的可持续发展模式.

企业风险管理与经营效率：来自中国保险业的经验证据

本文从风险管理的视角对企业效率评估的数据包络分析技术进行了改进,探讨了风险管理与经营效率的内在关联,并以中国保险业为例,对1999年以来企业真实的经营效率水平进行了评估。结果表明：企业内部的风险管理能力对其经营效率水平的提升具有明显的影响,而且这种影响力正在逐渐加强。不考虑企业内部的风险管理水平将直接导致其经营效率的测算结果出现低估,2002年以后这种低估的程度越发明显,这可归因于同期保险企业开始逐渐重视提高自身的风险管理能力。以上结论也为企业如何在管控风险的同时提升经营效率水平提供了有价值的指导。
