The feasibility of including sustainability in LCA for product development

The feasibility of combining the concept of sustainability principles and the methodology of Life Cycle Assessment (LCA) is examined. The goal is to achieve an operational tool that incorporates sustainability in product development and strategic planning. While the method outlined has the structure of LCA, it emphasises aspects and parameters often omitted from traditional LCA. The analysis and results can be either qualitative or semi-quantitative. Although a qualitative analysis is less time consuming, it can still highlight the important issues. Qualitative information, which is easily lost in a quantitative analysis, can be emphasised. One of the conclusions is that the method is well suited for screening analysis.     

A profile of environmental science in China

This paper concisely introduced the eco-environmental survey in China and the Chinese scientific programme for environmental research which is being practiced or being planned. China has established a nation-wide system relating to environmental scientific research and environmental administration and has taken the following strategies for solving the environment problems: (1) a series of laws and regulations for environmental protection has been promulgated so as to strengthen the legal administration and economic punishment. (2) the idea of ecological construction has been proposed for the purpose of taking the environmental protection work into the consideration of the national and provincial (or regional) economic construction planning. (3) spreading ecological engineering and ecological technologies have reduced the pollutant sources and have increased the industrial and agricultural economic profit.     

基于生态功能考虑的西北干旱地区生态需水研究

在当前生态需水研究的基础上,选取植被盖度作为衡量绿洲生态功能的主要指标,根据植被盖度和侵蚀率之间的关系,从生态系统的需水机理出发,提出了基于生态功能考虑的西北干旱地区生态需水量计算方法.以额济纳绿洲为例,计算了2000年额济纳绿洲生态需水,并与额济纳绿洲不同时期的生态需水进行了对比分析.     

乙酸型顶极群落的内平衡与反馈调节机制研究

通过产酸脱硫反应器处理高浓度硫酸盐有机废水的连续流试验，从“动态”角度考察COD／SO4^2-比改变引起的pH值、氧化还原电位（ORP）、碱度（ALK）和末端产物（VFAs）等的变动及生态因子的叠加效应引发的优势种群变迁，分析了乙酸型顶极群落的稳定性及其发生定向性生态演替的规律，进而阐明了乙酸型顶极群落抵抗环境压力的内平衡与反馈调节机制，并指出乙酸型代谢和乙酸型顶极群落是产酸脱硫生态系统的典型特征。     

战略环境评价在环境与发展综合决策中的作用

建立环境与发展综合决策机制是加强宏观环境管理的着眼点和突破口，其中战略环境评价（SEA）是重要工具，回顾了SEA的概念及发展，从技术支持，运行框架和长远效益几方面论述了SEA所能发挥的核心作用。划分SEA的不同工作模式，阐述其综合决策特征，归纳SEA的成功因素，提出我国开展SEA的建议。     

战略环境评价的工作程序

介绍了战略环境评价（法规、政策、计划和规划层次）工作程序的三个环节：评价方案的制定、评价实施和评价总结。并提出了战略环境评价指标体系制定的原则、战略环境评价的具体步骤及战略环境评价报告书的基本内容。     

工业污染源综合评价层次分析法

根据层次分析法原理，可将污染源分解成污染要素，再分解为影响因子再分解为次级因子层，构造污染源评价的多层次评价结构模型，根据评价对象的性质和特点，建立指标体系，再据确定的取值规则，以各因子层构成准则层，以各污染源构成方案层，建立判断矩阵计算总排序权值，进行污染源综合评价。     

销毁遗弃化学武器的环境风险评价方法研究

为履行《禁止化学武器公约》，各缔约国销毁化学武器的工作已启动。根据当前世界上化学武器的销毁情况，并针对二战期间在中国遗弃的化学武器的特点，给出了一套适应化学武器销毁流程的环境风险评价方法和技术。这套方法对将在我国进行的销毁遗弃化学武器风险评价工作有一定的实际意义。
