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]     

钢结构件生产加工项目环境影响评价技术浅议

介绍了钢结构件生产加工项目环境影响评价中工程分析、污染防治措施以及清洁生产等方面的环境影响评价要点，以期为同类项目的环境影响评价、污染治理和环境管理提供参考。     

城市水业私有化问题分析及研究

私人投资水业在今后一定时间内是解决城市基础设施建设的主要手段之一.它能够解决城市基础设施投资资金短缺的问题;实现基础设施行业投资结构多元化,促进体制改革;引入竞争机制,提高服务质量;引入先进技术与科学的管理手段,提高经营管理效率.本文首先介绍了私有化的概念,进而指出城市水业的私有化并不是解除政府保障基本水服务的职责,而是完成运营者到监管者的转变,最后以典型案例分析了私人投资水业存在着巨大的机会和风险.

松华坝水库水体营养状况评价与污染控制

采用中国环境监测总站<湖泊(水库)富营养化评价方法及分级技术规定>(2001年12月)中的综合营养状态指数法评价2004年松华坝水库水体的营养状况枯水期均处于贫营养状态;平水期处于贫营养和中营养状态;丰水期均处于中营养状态,出现了富营养化的征兆.针对丰水期水体已面临轻度富营养化的威胁,提出防治对策与建议.     

洱海水质分析及综合评价

本文择取整理了１９８０－１９９０年洱海水质监测资料，选用ＰＨ值，溶解氧、ＢＯＤ５高锰酸盐指数、ＴＮ和ＴＰ６个项目，分析和综合评价洱海水质在枯，丰，平不同水文期的质量及变化规律。洱海水质在平水期属Ⅰ类，丰水期属Ⅱ类，枯水期属Ⅲ类。
