鄱阳湖水质状况分析与评价

鄱阳湖是我国最大的淡水湖,对其水质的监测和分析有着重要意义。本文通过1980～1988年水质监测资料的搜集整理,分析了鄱阳湖水质的时空分布规律,并作出了比较全面的评价。评价结果表明,鄱阳湖已受到轻度污染,但其水质总体状况尚属良好,是全国淡水湖泊中最好的湖泊之一。     

21世纪中国环境法制建设的理性回归

本文从近几年我国环境法制建设状况的统计入手，详细地分析了近年我国环境问题的特点和环境法制建设的特点。但是，环境问题在我国仍然非常严峻，我国的环境法制建设仍然有诸多的缺陷，而且新世纪我国社会经济发展呈现出了新的特点。基于此，文章从六个方面对新世纪我国的环境法制建设进行了冷静地分析与思考，并因此得出相应的结论。     

我国环境法律效力体系与司法救济途径探讨

我国在现代化进程中存在着日益严重的环境问题,环境法治显得尤为迫切,而法治的前提必须是建立科学、完善的法律效力体系。文中归纳了我国环境法律效力体系,解析环境法治存在的主要问题,并探讨公民环境权利司法救济的途径。     

风向变化对城市大气污染的影响及试验分析

针对城市大气污染的复杂多变状况，在理论分析的基础上，通过风洞实验对城市大气污染扩散模型进行了模拟试验研究，建立了适合一定条件下城市大气污染物扩散的数学和物理模型，并对城市大气污染状况的影响因素进行了分析，在得到特定条件下城市大气污染扩散普遍规律的同时，重点讨论了风向变化对城市大气污染的影响，该方法同时还可以应用于城市大气污染物扩散浓度的估算。     

Significant developments in sustainable development law and governance: A proposal

This article develops a practical proposal for progress on sustainable development law. It examines the prospects for an international sustainable development law to provide a framework for more effective, coherent governance. Sustainable development law is briefly defined and an analytical framework is provided. Different degrees of integration between economic, social and environmental law are described. Certain principles of international law related to sustainable development are also highlighted. It is argued that these principles may serve to guide law‐makers and jurists where social, economic and environmental law and policy conflict or overlap. Continuing, underlying questions of sustainable development governance are addressed and its global frameworks analysed. The article also focuses on the 2002 World Summit on Sustainable Development, held in Johannesburg in August‐September 2002, and its specific mandate for the United Nations Commission on Sustainable Development (UNCSD) to take related legal developments into account. The article advances a proposal: that governments, economic, social and environmental intergovernmental organizations and other actors establish a ‘network of inquiry’ with members from relevant groups, including legal and academic organizations, and other expert groups, in order to follow, research, analyse and debate legal developments in a balanced way.

液固比对含重金属水泥熟料制品中重金属释放的影响

通过模拟煅烧试验制取水泥熟料,参照JGJ 55-2000（《普通混凝土配比设计规程》）制取混凝土样品,参考SR003.1和NEN 7375浸出试验,分别研究液固比对粒状及块状混凝土样品中重金属（Cr、Ni和As）释放的影响。结果表明,在不同液固比条件下粒状混凝土中的重金属浸出浓度为Cr>Ni>As,Cr、As浸出浓度基本保持不变,分别为2 500 μg/L左右和5～6 μg/L,Ni在液固比（L∶S）<6时,浸出浓度随着液固比的增加而降低,在L∶S>6时,浸出浓度较稳定,为35.7～41.5 μg/L;浸出量均随着液固比的增加而增大。液固比（L∶S）<10时,块状混凝土中重金属累积释放量及扩散系数均随液固比的增加而增大,当L∶S>10时两者基本保持不变。     

Comparison of China’s Environmental Impact Assessment (EIA) Law with the European Union (EU) EIA Directive

In this paper, we first review the development of China’s Environmental Impact Assessment (EIA) system in the past 30 years. Then we compare the framework and operational procedures of China’s new EIA law with those of the EU EIA Directive. We also compare public participation, as well as sanctions and control in the two EIA systems. In addition, we identify where the processes in both EIA systems are similar or different from one another. By comparison, we noted that there are at least three obvious weaknesses in China’s EIA system: (1) the application of new models for EIA legislation; (2) the improvement of EIA guidance and education; and (3) the enhancement of public participation in EIA process. Our study indicates that these three major shortcomings should be overcome and improved in China’s EIA system, when compared with the EU EIA system.
