时下,在各版本的地理教材、教参和报纸杂志上,英文缩写名词频繁亮相,这不仅是地理教学的需要,也是课改适应国际化要求的必然。笔者整理了若干地理教学中常用的英文缩写名词,以备参考。●API(Air Pollution Index,空气污染指数)是一种反映和评价空气质量的方法,即将常规监测的几种空气污染物的浓度简化成为单一的概念性数值形式,并分级表征空气质量状况与空气污染的程度。其结果简明直观,使用方便,适用于表示城市的短期空气质量状况和变化趋势。空气污染指数的确定原则:空气质量的好坏取决于各种污染物中危害最大的污染物的污染程度。空气污染指数是根据环境空气质量标准和各项污染物对人体健康和生态环境的影响来确定污染指数的分级及相应的污染物浓度限值(见下表)。
Nowadays, English abbreviations appear frequently in all versions of geography textbooks, teaching reference books and newspapers and magazines. This is not only the need of geography teaching, but also the necessity of curriculum reform to meet the requirements of internationalization. I compiled a number of geography teaching common abbreviations, for reference. • The Air Pollution Index (API) is a method of reflecting and evaluating air quality by simplifying the concentration of several regularly monitored air pollutants into a single conceptual numerical form and characterizing air quality status and air Degree of pollution. The results are concise and intuitive, easy to use and are suitable for representing the city’s short-term air quality conditions and trends. Air pollution index to determine the principle: the quality of air depends on the various pollutants most harmful pollutants pollution levels. Air pollution index is based on the ambient air quality standards and the impact of pollutants on human health and ecological environment to determine the classification of pollution index and the corresponding pollutant concentration limits (see table below).
