昆山市环境监测网络调整的构想

环境监测网络是环境质量监测的基础,要准确全面反映地域环境质量必须要建设好的环境监测网络。近年来,昆山的环境现状发生了巨大变化,随着环境现状的改变,相应的监测网络和点位的功能也不断发生变化,现有的监测网络存在不少问题和不足。通过对昆山市现有环境监测网络的分析,找出了其中的问题和不足,并提出了监测网络和布点调整的构想。指出只有依托现有环境分布状况和发展规律,通过合理的规划,不断进行调整,才能建设具有典型意义的监测网络。     

Contesting sustainable development: low-impact development in Pembrokeshire Coast National Park

This paper assesses the credentials of the planning system in dealing with low-impact developments in the countryside. Forming part of the wider debate on sustainable development in the UK, low-impact developments challenge contemporary rural planning orthodoxy. A detailed case study of Brithdir Mawr in Pembrokeshire Coast National Park reveals the complexities and sensitivities inherent in operationalizing sustainability in this context. The results reveal a planning system reluctant to embrace unconventional lifestyles and methods claiming to be sustainable. It is concluded that the planning system and low-impact developments both need to demonstrate their sustainability credentials in a more direct and empirical manner. Ultimately this could be built into revised criteria for allowing dwellings in the open countryside. Copyright © 2001 John Wiley & Sons, Ltd.     

缺氧及两级好氧处理岳阳化工总厂部分废水的运行与分析

介绍了岳阳化工总厂部分废水的处理工艺和设计，针对原水水质COD高等特点，采用缺氧，两级好氧工艺，该厂进生化池：COD浓度1000－14000mg/L,BOD3:COD=0.5左右；出生化池：COD浓度＜120mg/L，低于GB8978－1996表4中石油化工工业规定的Ⅱ级排放标准，BOD3＜10mg/L^ ，低于GB8978－1996表4石油化工工业规定的1级排放标准。     

我国城市缺水问题及其缓解途径

我国目前有近３００个城市缺水,缺水问题己成为城市经济建设发展的重要制约因素之一。城市经济建设的持续发展影响着全国经济建设顺利发展的进程,所以,解决好城市缺水问题则成为关系到全局的重大课题。今后应进一步提高水的利用效益,在全面节流的基础上多途径开源。不断提高工业用水的重复利用率,并控制水污染,加速实现城市污水资源化。应制定鼓励节约用水的技术经济政策,支持节水型设备改造,调整产业结构和工业布局。缺水城市要限制需水多的行业发展。     

公共信用视角下的安全生产模式及其信用机制

为探析当前安全生产问题的深层原因,改进安全生产工作方式,探索构建安全生产长效机制,根据对政府、企业和职工等不同主体在安全生产领域中的公共信用分析,发现主体两两之间存在信用关系,进而发现安全生产信用模式。在信用模式的基础上,指出当前安全生产的问题在于主体信用缺失或信用关系扭曲,且缺乏强大的社会力量和规范的市场机制监督、评估与约束不同主体的信用行为,尚未形成安全生产信用机制。论证得出:构建法治化、市场化和社会化的安全生产信用机制是治理当前安全生产问题的有效途径,同时也是安全生产发展的必然趋势。     

当代大学生勤俭精神缺失的原因及对策

Mortality,violence and lack of access to healthcare in the Democratic Republic of Congo

The people of the Democratic Republic of Congo for decades have been living in a situation of chronic crisis. Violence, population displacement and the destruction of infrastructure and health services have devastated the health of the population. In 2001, Médicins Sans Frontières conducted a survey in five areas of western and central DRC to assess mortality, access to health-care, vaccination coverage and exposure to violence. High mortality rates were found in front-line zones, mainly due to malnutrition and infectious diseases. In Basankusu approximately 10 per cent of the total population and 25 per cent of the under-five population had perished in the year before the survey. Humanitarian needs remain acute across the country, particularly near the front line. Infectious-disease control and treatment are a priority, as is increasing access to health-care. Humanitarian assistance must be increased considerably, especially in rural areas and zones that have been affected directly by conflict.
