| 摘 要： | 大气环境中氮,硫污染物的循环,正在自然系统改变。人为活动已明显冲击了氮、硫元素的循环过程,它们可能对生物多样性,局地气侯变暖,土壤,水体,人体健康等逐渐带来严重影响。氮、硫污染物亦是大气酸沉降的主要来源。通过对甘肃平凉市大气湿沉降中氮、硫污染物特征分析,掌握氮、硫污染物动态变化,分析它们在大气湿沉降中的化学变化及污染循环特征,为做好节能减排工作提供理论依据。使氮、硫元素的循环趋于平衡,防止酸沉降在我市发生,进一步提高我市环境空气质量。

| Abstract: | The natural system of nitrogen and sulphur pollutants circulation in air environment is changing.The human activities effect circular processes of nitrogen and sulphur elements,and they can cause serious impacts on biodiversity,partly climate warming,soil,water body,human health.Through characters analysis of nitrogen and sulphur pollutants in air wet precipitation,the dynamic changes of nitrogen and sulphur pollutants are mastered,and it can provide theoretical proof for energy-saving and emission-reducing... |
