Accidents and risk control

A framework for transformation of knowledge and experience from risk analysis to emergency education is presented. An accident model was developed built on the concept “uncontrolled flow of energy (UFOE)”, where essential elements are the state, location and movement of the energy. A UFOE can be considered as the driving force of an accident, e.g. an explosion, a release of heavy gases. A domain model has been developed for representing emergencies occurring in society. A domain is a group of activities with allied goals and elements, and the domain model uses three main categories: status, context and objectives. Ten specific domains have been investigated including process plant, energy production and distribution, natural disasters and different sorts of transport. Totally 25 accident cases were consulted and information was extracted for filling into the schematic representations with two to four cases pr. specific domain.     

以造粒粉煤灰为过滤介质去除景观水中磷的研究

研究了造粒粉煤灰的最大磷吸附量、磷吸附速率等吸附特征，以及颗粒粒径、磷浓度、水力负荷对景观水除磷效果的影响。还进行了为期21天的连续过滤试验，发现滤床在高水力负荷条件下能持续地去除景观水中的磷。

遥感技术在小城镇发展规划中的应用

对卫星遥感技术在小城镇发展规划中的应用进行了分析，包括小城镇空间布局信息分析、小城镇区位分析和小城镇环境污染分析，介绍了遥感技术在小城镇变化监测中的应用。分析表明，遥感技术能为小城镇发展规划提供众多基础数据，具有广阔的应用前景，但不能完全取代地面调查。     

主题旅游活动项目策划研究--以峨眉山"2004年百姓生活游"旅游活动项目策划为例

自1992年以来，我国国家旅游局每年推出一个专项旅游产品作为对外宣传口号。为配合此项活动的开展，各地纷纷组织了相应的主题旅游活动。通过主题旅游活动的开展，能够有效地整合区域旅游资源、提升旅游目的地形象、丰富旅游目的地产品类型、促进旅游基础设施和服务设施建设、弘扬当地传统文化。通过对峨眉山“2004年百姓生活游”主题旅游活动项目策划的研究，对主题旅游活动项目策划的理论与方法进行了初步探讨。     

区域风险评价方法研究

基于定量风险评价的基本原理,提出一种区域风险评价方法。主要针对有多个重大危险源存在的区域,在对单个危险源进行风险评价的基础上,应用叠加原理得到描述该区域整体风险状况的定量评价结果。同时考虑了消防部门和医疗机构在事故应急救援中的积极作用,并将其量化为区域风险的补偿系数。通过实例验证了该方法的可行性,展示了该方法的应用效果。区域风险评价方法不仅能够反映区域风险的分布状况,而且对区域重大危险源的规划和布局具有较好的决策支持作用。

TRANSIENT RESPONSE FUNCTIONS FOR CONJUNCTIVE WATER MANAGEMENT IN THE SNAKE RIVER PLAIN,IDAHO1

ABSTRACT: Increasing demands on western water are causing a mounting need for the conjunctive management of surface water and ground water resources. Under western water law, the senior water rights holder has priority over the junior water rights holder in times of water shortage. Water managers have been reluctant to conjunctively manage surface water and ground water resources because of the difficulty of quantification of the impacts to surface water resources from ground water stresses. Impacts from ground water use can take years to propagate through an aquifer system. Prediction of the degree of impact to surface water resources over time and the spatial distribution of impacts is very difficult. Response functions mathematically describe the relationship between a unit ground water stress applied at a specific location and stream depletion or aquifer water level change elsewhere in the system. Response functions can be used to help quantify the spatial and temporal impacts to surface water resources caused by ground water pumping. This paper describes the theory of response functions and presents an application of transient response functions in the Snake River Plain, Idaho. Transient response functions can be used to facilitate the conjunctive management of surface and ground water not only in the eastern Snake River Plain basin, but also in similar basins throughout the western United States.
