空气污染指数模式的改进

我国目前以空气污染指数API报告各城市的环境空气质量。由于我国各地环境空气质量状况差异很大,该方法在报告城市空气质量时具有较大的片面性,不能综合反应污染状况。本文针对现行的API指数法进行了模式推算和改进,新的计算模式可更客观全面地反映城市空气质量。

Method of pollution sources assessment in relation to residential site selection

Much investigation supports a high incidence of disease and death rates when people live in ambient polluted air for a long time. Thus, the location of residential sites is important from a public health viewpoint. The method outlined in this paper is useful for determining the location of residential sites based on pollution sources assessment.

京津风沙源区防风固沙功能的时空变化及其区域差异

防风固沙功能是京津风沙源治理成效的关键监测指标。以往研究注重局地防风固沙功能的评估,对全区防风固沙功能的时空变化与内部差异揭示不足。基于京津风沙源区多期遥感数据,采用修正风蚀方程与GIS空间统计技术,评估分析了2000-2015年防风固沙功能的整体变化及其区域差异。结果表明:(1)京津风沙源区年均防风固沙量为28.98亿t,防风固沙能力为68.24 t/hm~2,且均随年份变化波动增加,年均增速分别为1.10%和0.71%;(2)京津风沙源区防风固沙能力呈西北高、东南低趋势,有49.06%的区域防风固沙能力高于70 t/hm~2,评估期内有54%的区域防风固沙能力明显提高;(3)浑善达克沙地亚区、典型草原亚区和荒漠草原亚区的防风固沙量累计为全区防风固沙总量的88%,燕山丘陵山地水源保护亚区和晋北山地丘陵亚区的防风固沙能力提升最显著;(4)锡林郭勒盟、赤峰市和乌兰察布市的防风固沙量合计占全区防风固沙量的77%,朔州市与包头市防风固沙能力较高,北京市与天津市防风固沙能力增速较高。因此,未来应重视分区施策治理与西部和北部防风固沙功能提升。     

Optimising the environmental benefits of emission reductions from UK coal- and oil-fired power stations: a critical loads approach

This paper describes a method for determining reductions of SO₂ emissions from coal- and oil-fired power stations, oil refineries and large industrial units in the UK taking into account their pollution potential. The method is based on the use of two gridded data sets: critical loads, which represent the sensitivity of the environment to acid deposition and modelled estimates of total (wet + dry) sulphur deposition for 646 point sources within the UK. An iterative method is used to identify and subsequently reduce emissions from point sources that contribute most to areas of critical loads exceedance. This paper demonstrates how the method may be used to determine an optimal allocation of emissions across the UK which yields the maximum amount of environmental protection per unit of emission.The paper then goes on to consider the changes that will have to take place within the UK power generation industry in order to meet the revised EC Large Combustion Plant Directive which comes into force on 1 January 2008. Particular emphasis is placed upon proposed emissions trading schemes and the environmental implications of allowing trading between stations with high and low pollution potentials. The paper concludes by suggesting that the emissions trading process should take into account the pollution potential of each source, irrespective of whether the proposed emission is within the plant's agreed emission limit. An approach based entirely on minimizing environmental damage rather than one which takes cost into account, as in current integrated assessment modelling, could provide an interesting approach across the rest of Europe.
