A PROPOSED APPROACH TO COORDINATION OF WATER RESOURCE DEVELOPMENT AND ENVIRONMENTAL REGULATIONS1

ABSTRACT: The planning and developing of water resources to meet the country's needs for water supply, flood control, hydroelectric power, irrigation, and navigation now needs to take more account of environmental needs and regulations. Water resource development is often beneficial to the environment, but may also be harmful, as in cases involving salmon and various other endangered species. As a national objective, the environment must be preserved and in some cases restored; but how can this be done consistent with other national objectives, relating to life and welfare of human beings? This problem has aroused the concern of many engineers and water scientists. As a result, a national conference on this subject was held in Chicago in June 1998, as an integral part of ASCE's Annual Conference on Water Resources Planning and Management and the Annual Conference on Environmental Engineering. At the conclusion of that conference, a post-conference meeting was held by a group of prominent water resource practitioners. It was concluded at this meeting that action should be taken by our government to establish a new form of interagency approach, involving the states, as a means of coordination in cases of national importance.     

TiO2/Ni PECO体系降解DMP的动力学和光电协同作用研究

以采用微波辅助法制备的TiO₂/Ni光电极为阳极,纤维状石墨毡材料(graphite felt,GF)为阴极,饱和甘汞电极(saturated calomel electrode, SCE)为参比电极建立TiO₂/Ni 光电催化氧化（PECO）体系。以邻苯二甲酸二甲酯（dimethy phthalate,DMP）为目标物,研究其光电催化降解反应动力学和光电协同作用。结果显示：DMP的降解符合拟一级动力学规律;当DMP初始浓度一定时,影响DMP光电催化降解速率的因素由强到弱依次为：催化剂有效面积,紫外光强度,曝氧速率,外加偏转电压等。实验证明本体系中光电之间具有协同作用。

我国高校可持续发展教育的挑战、对策及展望

本文在综述可持续发展教育概念、总结国内外高校可持续发展教育现状的基础上,分析提出了我国高校可持续发展教育在组织管理、学科壁垒、课程设置、资源平台、经费支持等五个方面面临的挑战,并结合同济大学在推进可持续发展教育方面的模式创新,浅谈我国高校可持续发展教育应对这五大挑战的对策。文中指出在我国处于跨越式发展、加快转变经济增长方式的攻坚阶段,可持续发展教育是国家实现可持续发展的重要途径,具有特殊的时代意义,加强高校可持续发展教育成为新形势下推进可持续发展教育改革的新动力。在此背景下,我国教育系统,特别是承担培育国家未来人才的高校应抓住这一机遇,将可持续发展纳入高校的议事日程,充分利用高校学科专业齐全的优势,积极开展跨学科教育,借鉴国内外可持续发展教育经验,在可持续发展教育、科研、对外合作等方面实现创新和突破,参与、促进并解决可持续发展问题。

能源安全视角下中俄能源合作战略选择

中俄能源合作是中俄两国经贸合作的重要组成部分,也是发展两国战略协作伙伴关系的重要领域。中俄两国能源合作既有利于缓解中国能源安全紧张问题,也有利于俄罗斯开拓广阔的能源消费市场,促进本国经济发展,同时对地区经济发展起到重要作用。分析了中俄能源合作的背景、基础、特点与障碍,提出了发展中俄能源合作的战略选择。     

基于元胞自动机的弱视条件下群体疏散的仿真研究

根据人在弱视情况下的行为特征,建立基于元胞自动机的逃生模型,对弱视情况下的人群疏散进行了模拟。模拟过程中考虑了人的学习能力及人与人之间的相互作用等因素,模型加入吸引子使模拟人的疏散行为更为灵活。基于人能通过熟悉周围环境作出合理判断的学习能力,引入了"积累步长"的概念,使人的沟通判断能力(走过的路径、边界和出口位置通过交流能够获取)在模型中得到体现。获取足够信息的人可以避免多余的寻找,降低了逃生时间,体现了"人多力量大"的互助行为。通过大量的模拟实验,并讨论不同的环境条件对人群疏散的影响。     

面向双重区位发展机遇的湖南省旅游发展战略研究

湖南参与了多个区域旅游合作战略,其中泛珠三角和中部6省合作战略是影响湖南旅游经济发展的两大重要外部力量,两大区域合作给湖南旅游业带来了新的发展机遇。在分析它们给湖南旅游发展带来发展机遇的基础上,提出了建立专门的行政组织来强化区域协调管理、利用区域内旅游资源特性实现旅游资源的联动、借助区域旅游市场的互动实现客源市场丰富的地区对湖南旅游市场的支撑、增加区域旅游合作的地域便捷性等对策。     

Avoiding the presumptive policy errors of intergovernmental environmental planning programmes: a case analysis of urban stormwater management planning

This social research aims to identify and examine the implementation presumptions of intergovernmental environmental planning programmes and how to improve their effectiveness in future practice. It contrasts and explains the organisational dynamics and implementation responses of municipalities that succeeded and failed in realising the objective of such a programme. The research involved a qualitative multiple-case comparison between four high- and four low-performing municipalities implementing a stormwater programme within metropolitan Sydney, Australia. These two organisational types substantially differed in corporate expertise, environmental leadership, extended relational activity, and overall disposition to learning and ownership of local environmental issues. The paper identified five presumptions underpinning the programme design which privileged the high-performing organisations, but did little to garner commitment and develop capacity among the low-performing group. These implementation insights not only provide guideposts for intergovernmental programme design, but also reveal how policy design can undermine policy intent if empathy to local organisational dynamics is lacking.     

浅析高职院校校企合作办学模式

校企合作有其发展的理论基础、历史必然性和优越性,是经济发展对职业教育提出的客观要求,是职业教育必走的道路。目前我国高职院校校企合作存在内容和形式参差不齐,企业缺乏积极性,学校实力不足以及国家缺乏制度保障的问题,必须通过提高企业积极性,增强学校的师资力量,制定相应的法律法规和树立校企合作发展的观念来改善我国高职院校校企合作的现状。
