生命周期评价数据库分析与建模

基于关系数据库和面向对象程序设计理论建立了生命周期评价数据库系统。通过综合分析生命周期评价数据，根据生命周期评价数据的数据类型，将数据分为产品评价数据、产品档案数据、基础材料数据和影响评价基础数据，相应的设计了4个数据库。运用关系数据库理论分别对4个数据库建立了物理结构模型。     

莱州湾西部海域枯水期富营养化程度研究

根据2004年5月份的调查资料,选择透明度、盐度、活性磷酸盐、溶解无机氮、硅酸盐、叶绿素a、浮游植物、浮游动物、底栖生物作为评价因子,利用层次分析法确定了各因子的层次关系和权重,建立了以营养盐和富营养化症状为基础的综合评价指数模型,对莱州湾海域的营养水平进行了评价.各站点最终评价结果表明:莱州湾海域磷酸盐、无机氮超标严重,整体已表现出富营养化,其中黄河口和小清河口附近富营养化较为明显,这主要是受到陆源排污和海水养殖的影响,基本符合实际情况.

New findings on the generation of waste and emissions, and a modified cleaner production assessment approach-illustrated by leather production

New findings on the causes of waste and emissions, which were obtained from analysing numerous material streams in various sectors of industry, are presented in this article. It describes the implications of these findings for the vision of clean production, for formulating environmental policy concerning cleaner production targets, for the opportunities to assess to what extent the cleaner production targets have been met, and for the cleaner production assessment. A modified cleaner production assessment approach is presented, and illustrated using leather production as an example. The consequent implications for the diffusion of cleaner production are discussed.     

从摇蓝到坟墓的污染预防:生命周期评价

随着污染形势的恶化,原有的亡羊补牢式的污染末端治理已经不能够满足环境污染发展的新要求,生命周期评价的概念就是从一个更宏观的角度,以更全面的视角来分析环境污染的产生和预防;本文从生命周期评价的概念、发展、方法和应用等几个方面对其进行较为全面的介绍.

Spatial distribution of ecological security status assessment of West-Liaohe River based on geographic information system

Eco-security assessment is a hot research area in resource and environmental science, which involves data with much spatial, non-linear, and random features. Geographic information system (GIS), as a useful tool to analyze and manage spatial information, has a superior advantage in this field. A case study in the western part of the Liaohe River featuring a method of eco-security spatial differences (ESSD) based on GIS is developed in this paper. The method includes four steps: 1) developing the pressure-state-response (P-S-R) framework with site data; 2) digitizing West-Liaohe River and setting its GRID database of ecosecurity assessment indicators; 3) figuring out the relative membership degree (RMD) of eco-security indicators by using the analytical hierarchy process with the weight of indicator; 4) classifying the security zone and mapping the assessment result of eco-security status in grid by GIS method of assigning and clustering. The visual spatial differences of eco-security based on GIS enables decision makers to know the status of eco-security better in making policies for achieving sustainability. __________ Translated from Environmental Science, 2005, 26(5): 28–33 [译自: 环境科学]     

中国现行环境影响评价制度若干问题探讨

环境影响评价制度是中国环境保护法中的一项非常重要的基本制度.但是在实践中存在价值判断、环保执法、公众参与等问题,并没有达到调整产业结构、转变经济增长方式、实现经济社会环境可持续发展的预期效果.本文分析了环境影响评价制度在实践中存在的主要问题,并提出相应的改进建议.
