The integrated project AquaTerra of the EU sixth framework lays foundations for better understanding of river-sediment-soil-groundwater systems

The integrated project "AquaTerra" with the full title "integrated modeling of the river-sediment-soil-groundwater system; advanced tools for the management of catchment areas and river basins in the context of global change" is among the first environmental projects within the sixth Framework Program of the European Union. Commencing in June 2004, it brought together a multidisciplinary team of 45 partner organizations from 12 EU countries, Romania, Switzerland, Serbia and Montenegro. AquaTerra is an ambitious project with the primary objective of laying the foundations for a better understanding of the behavior of environmental pollutants and their fluxes in the soil-sediment-water system with respect to climate and land use changes. The project performs research as well as modeling on river-sediment-soil-groundwater systems through quantification of deposition, sorption and turnover rates and the development of numerical models to reveal fluxes and trends in soil and sediment functioning. Scales ranging from the laboratory to river basins are addressed with the potential to provide improved river basin management, enhanced soil and groundwater monitoring as well as the early identification and forecasting of impacts on water quantity and quality. Study areas are the catchments of the Ebro, Meuse, Elbe and Danube Rivers and the Brévilles Spring. Here we outline the general structure of the project and the activities conducted within eleven existing sub-projects of AquaTerra.     

码头工程建设方案安全评价的研究

为了对码头工程建设方案进行安全评价,根据国家发展和改革委员会、国家安全生产监督管理局关于加强建设项目安全设施"三同时"工作的通知要求以及我国港口安全评价管理办法,选取码头工程港址选择,总平面布置,装卸工艺方案,水工结构、护岸、堆场地基与面层结构,道路交通,配套工程,自然条件,安全管理与劳动力素质等8个因素,设计了一套多指标综合评价体系;利用未确知数学理论,通过建立未确知测度模型、置信度识别准则并分析其指标因素,确定指标因素的可靠程度,提出一种基于未确知测度的利于码头工程安全设计管理及监察的科学的码头工程建设方案安全评价新方法;选取南方某港5000吨级通用码头工程建设方案进行验证。     

地铁项目安全绩效关键影响因素分析研究

在分析研究地铁安全事故案例的基础上,识别出对地铁项目安全绩效的48个关键影响因素,将这些影响因素归为五大类,即项目参与各方对安全的影响程度、人员的不安全行为及不安全状态、材料的不安全状态、机械/设备的不安全状态和现场环境的不安全状态;采取调查问卷的方式,运用结构方程建模得出各个指标的重要度及各指标之间的相互影响。研究结果表明:"项目参与各方对安全的影响程度"和"现场环境的状态"对地铁安全绩效的贡献最大,同时,其他因素也有较强的影响,在地铁施工中应以此为重点,加强安全防范。     

"以人为本"是房地产建设项目环境影响评价中的重要原则

房地产开发项目体现“以人为本”理念和对环境影响的双重性，在房地产建设项目环境影响评价中应以“以人为本”的原则加深其服务功能和环境保护目标的属性，实现房地产开发项目和谐共生的生态环境和可持续发展。     

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。     

个旧贾沙乡滑坡成因及防治措施研究

贾沙滑坡属大型牵引式滑坡,处于蠕变阶段.滑坡体为第4系粉砂夹粘土层.研究其形成原因对滑坡防护与治理有重要的意义.从贾沙滑坡的成因角度出发,提出贾沙滑坡的防治措施应全面做好各种词查(勘察)工作,尽早防止,科学施工,尤其是产生滑坡的主要成因--水的防治措施必须尽快解决,以防止不必要的损失.     

River systems as providers of goods and services: a basis for comparing desired and undesired effects of large dam projects

In developing countries, large dam projects continue to be launched, primarily to secure a time-stable freshwater supply and to generate hydropower. Meanwhile, calls for environmentally sustainable development put pressure on the dam-building industry to integrate ecological concerns in project planning and decision-making. Such integration requires environmental impact statements (EISs) that can communicate the societal implications of the ecological effects in terms that are understandable and useful to planners and decision-makers. The purpose of this study is to develop a basic framework for assessing the societal implications of the river ecological effects expected of a proposed large dam project. The aim is to facilitate a comparison of desired and potential undesired effects on-site and downstream. The study involves two main tasks: to identify key river goods and services that a river system may provide, and to analyze how the implementation of a large dam project may alter the on-site capacity and downstream potentials to derive river goods and services from the river system. Three river goods and six river services are identified. River goods are defined as extractable partly man-made products and river services as naturally sustained processes. By four main types of flow manipulations, a large dam project improves the on-site capacity to derive desired river goods, but simultaneously threatens the provision of desirable river goods and services downstream. However, by adjusting the site, design, and operational schedule of the proposed dam project, undesirable effects on river goods and services can be minimized.
