突发事件机理体系与现代应急管理体制设计

本文为了增加对突发事件的科学认识,提升应急管理的能力水平,首先对突发事件和应急管理的内在机理进行剖析。通过分阶段、划层次地构建"4L-5S"机理分析模型,将二者划归为统一体系,以理清其逻辑内涵;然后,为顺应时代发展特征,满足应急管理的更高要求,实现应急管理工作从非常态协同应对转为常态化职能管理,对现代应急管理体制加以总体设计。从而,突发事件机理体系设计使得我国的突发事件机理研究逐渐过渡至具有阶段性和层次性,现代应急管理体制设计使得我国应急管理整合出具备现代思维理念的逻辑框架。     

喀斯特洞穴晶体沉积速率的气候响应

在对本寨洞9个滴水点沉积玻片的晶体沉积质量监测后发现,现代洞穴沉积量主要受控于温度变化,统计的8个玻片沉积中,有6个滴水点的沉积速率与温度呈正相关关系。滴水速率对沉积速率影响较小,在统计的8个滴水点中,只有BZ9滴水点受滴水速率影响明显,具有正相关关系。其环境意义为石笋的生长速率主要受温度控制,呈正相关关系,可作为古温度代用指标。     

时间序列沉积物捕获器（sediment trap）及其在青海湖的放置

沉积物捕获器在认识现代沉积过程方面具有独特的优势,已在海洋和国外一些大湖的研究中得到了成功的应用,但相关的工作在我国湖泊研究中尚未开展。Mark 8-13型时间序列沉积物捕获器是用来连续收集水体沉降颗粒物的仪器,可以获得沉积物输入通量和季节性变率。本文在介绍了该类型沉积物捕获器的设计、工作原理、投放和回收等基本知识的基础上,阐明了我们选择青海湖作为放置沉积物捕获器的理由和科学意义。在本专题的五篇论文中,我们展示了在青海湖放置的沉积物捕获器于2010年7月至2012年9月期间收集的沉积物和湖水样品的研究结果和同步的实时监测数据。通过在青海湖两年多的试验性地放置以及初步的结果,我们建议在我国典型内陆不同位置的湖泊等水体长期地放置这类沉积物捕获器,将为湖泊等水体系统的现代沉积和生物过程的深入理解提供全新的视角。

The 2006 war and its inter-temporal economic impact on agriculture in Lebanon

The July 2006 war waged by Israel on Lebanon caused an estimated USD 1 billion of direct (financial) damage to infrastructure. However, it generated also significant indirect (economic/inter-temporal) costs. One sector that suffered considerably in this respect was agriculture, the main source of income for 30–40 per cent of Lebanese. This paper's main objective is to develop a methodology to estimate the total—direct and indirect—cost of the war to agricultural crop production, using an area of south Lebanon as a focal point. The indirect loss assessment viewed inter-temporal reductions in crop production values as the opportunity cost of not working fields due to the presence of unexploded ordnance (UXO). Various crops were evaluated for two scenarios (50 and 100 per cent damage due to UXO) over UXO-clearance periods of five and 10 years. The results indicate that any damage estimates that include only direct losses will under-estimate total losses by 80 and 87 per cent for the five- and 10-year periods, respectively.     

构建现代产业体系的环保思考

Seven thousand years in the service of humanity—the history of copper, the red metal

Measured by weight, copper is the third most important metal used by man. The annual value of its 2007 output was on a par with the GDP of e.g. Ukraine. Copper is also one of the oldest metals, its employment going back 7000 years. For millennia, it was predominantly employed for decorative purposes, coinage and in warfare. Technical breakthroughs in antiquity, like smelting and alloying, expanded its production and enhanced its utility. Copper's true heyday occurred after 1850, with the usage of electricity. In the period since then, volumes increased 300-fold, while costs and prices declined. With impressive progress in the technology of its production and consumption, the red metal has been able to hold its own, despite the emergence over history of formidable substitutes like iron, aluminum, plastics and optic fiber.
