大气污染物总量分配公平性评价研究

污染物总量的合理分配是总量控制的核心内容,目前对于总量分配方案的公平性评价缺乏定量化依据,文章应用经济学Gini系数和Lorenz曲线的概念定量评价污染物总量分配公平性.以"十一五"期间广东省环保局下达到珠三角各城市的SO2总量分配方案为评价对象,考虑各地的环境容量、排放现状、人口和国内生产总值因素,计算基尼系数.结果表明:分配方案比较合理,能普遍被珠三角各城市所接受,但从社会经济发展和环境属性角度来看分配方案不够均衡,需进一步调整.     

深圳市污染物排放总量与近岸水体营养盐变化的统计分析(IV)

从统计学角度分析深圳市污染物净排放总量与其近岸东、西部水体富营养化之间关系。研究结果表明:深圳市东部海域水体活性磷酸盐、EI值以及西部海域水体中的N:P分别与近岸排污呈现较好的相关性,他们似可作为深圳排污与近岸水体富营养化关系指标。深圳东西部水体由于地理条件、海湾的封闭性的差异,造成东部水体更易受到深圳近岸排污的影响,而西部水体较为开放,受珠江水系、深圳和香港排污等多重因素的影响,因此在研究深圳近岸污染物排放总量与赤潮发生关系时,应选择东部水体作为研究对象。

Linkages between best practice in business and good environmental performance by companies

Is the adoption of currently accepted best practice in business associated with improved environmental performance by companies? What methods can be used to assess and compare the environmental practices and performance of different companies? In this pilot study, the business and environmental practices and performances of five companies in the metal working sector were examined and scored. The business practices and performances were assessed using the best practice model adopted in the Australian Manufacturers Council study (AMC, November 1994, Melbourne, 112pp.). The environmental practices and performance of the companies were assessed based on a five stage framework of business response to environmental issues presented here. A strong correlation was observed between environmental performance and business practices (correlation coefficient, r = 0.85, p < 0.05). The company closest to best practice had a strong focus on quality, efficiency and elimination of waste, well-developed strategy, good teamwork and a high level of commitment and also had the highest score for environmental performance. The company with poorest score for its business practices had the poorest environmental performance, with the remaining companies lying between on both scores. There was no significant correlation between business performance outcomes and environmental performance.
