城市供水管网漏损控制潜力研究

在我国各城市普遍缺水的同时，城市供水管网的漏损状况却相当的严重，科学衡量漏损控制的潜力，对于控制漏损和科学地进行城市水资源规划和需求管理非常重要。从技术潜力、经济潜力、社会潜力三方面将城市供水管网漏损控制的潜力进行了分析。提出了以社会最优值作为漏损控制的目标，以社会潜力作为需求管理的依据，同时综合考虑技术潜力和经济潜力。社会最优控制水平和企业的经济漏损控制水平之间有时会存在很大差异。科学的划分政府和企业在控制漏损的义务是非常必要的，如果需要企业的漏损控制水平小于经济漏损水平时政府应该给予一定的补偿，这样才能增加企业控制管网漏损的积极性。     

A review of EMAS in Greece: is it effective?

EMAS certification is a common practice among the European companies. However, based on the data from the Greek Ministry of Environment, only 10 companies were EMAS certified in Greece by December 2003. The aim of this study is to identify and summarize the experiences of the EMAS certified companies that operate in Greece. Based on the results of the study, the major advantage from the EMAS implementation seems to be the closer monitoring of the production process while the main cost item is the infrastructure upgrading.

高压变电站改造的安全监督管理

以茂名分公司动力厂南110kV变电站改造项目为例，从组织措施，安全教育，施工准备，现场安全管理等方面，阐述对高压变电站改造项目的安全监督管理。     

世行贷款昆明滇池流域管理项目效益分析

滇池流域环境管理项目主要是针对控制或削减磷的入湖负荷及其人它如ＣＯＤ，ＢＯＤ，悬浮物，氮等污染负荷而设置的。应用针对滇池对海磷负荷－水质响应的数学模型可以预测此项目的直观效益。即项目实施后，可以避免滇池水质的继续恶化，保持其原有功能，虽然水质的磷指标仍将维持现在的水平，但ＣＯＤ，总氮等污染物可望有一定程度的消减。

试论水质管理与饮水安全

随着生活水平的不断提高，人们对饮用水质量提出了更高的要求，而水环境质量的普通恶化又使人们不得不考虑饮用水的安全性。在简介了我国水资源现状的基础上，文中阐述了水质问题的重要性和我国水体环境质量的严峻性，指出了水质问题不仅制约着社会经济的发展，更直接地丰人们饮用水的安全性，已成为进入21世纪我国水资源问题的主要矛盾；在分析了我国水资源水质管理存在问题的基础上，从法律、法规、政策、经济等方面，着重探讨了加强水质管理与解决水资源供需矛盾和保证饮用水安全的关系。     

城市空气质量中长期预报的探讨

江苏省环境空气质量预报工作已开展多年,在这几年的预报工作中,发现现在使用的对未来24 h空气质量预报的方式上存在一些问题,从而限制空气质量预报发挥应有的作用.改进预报方式,在现有的空气质量预报的基础上,开展城市空气质量的中长期预报,有利于各级政府及环境管理部门,提前采取必要的措施,减少或控制污染的产生,从而避免城市空气污染事件的发生,以保护城市居民的身体健康.     

Climate anomalies, Indonesian vegetation fires and terrestrial carbon emissions

There was a widespread misconception about the causes of vegetation and land fires in Indonesia. At a certain point, the public perceived that fires and the associated haze pollution were primarily caused by smallholders' agricultural activities. In fact, there was a variety of land-use activities including large-scale land clearing following deforestation for further land development. El Niño events and the associated dry weather were sometimes quoted by officials and the media as the cause of fires. The fire episodes from 1980 to 2000 were analysed in connection with climate anomalies and the implementation of land-use policies related to forest conversions. The analysis employs long-term climatic and sea surface temperature data to reconstruct climate distributions and anomalies including Southern Oscillation Index (SOI), Sea Surface Temperature (SST) and Outgoing Long-wave Radiation (OLR). In this study, the terrestrial carbon emissions from vegetation fires were estimated based on official statistical data on area burnt. The possible incentives for sustainable land management were discussed in the light of fire prevention. The underlying cause neglected in the discussion of Indonesian vegetation fires was forest and land development policy. Legitimated in the early 1980s, it drove massive forest conversions and the use of fires for land clearing. El Niño Southern Oscillation (ENSO) provided dry weather suitable for biomass burning and widespread fire, but it was hardly the cause of fires. The estimate of area burnt in the big fires in 1997 was about 11.6 Mha, resulting in carbon release of 1.45 Gt, equivalent to 0.73 ppmv of CO₂, or almost half the annual global atmospheric CO₂ growth. Based on the current carbon market price such emissions by the 1997 fire episode were worth around US$ 3.6 billion.
