大气沉降对我国土壤中污染分布及元素循环的影响

大气沉降是污染物进入土壤的重要途径，也是土壤中污染物的主要来源。同时，大气沉降和土壤元素循环息息相关。本文综述了大气沉降对我国土壤中污染物分布以及元素循环的影响。结果表明，重金属沉降依赖于长期的干湿混合沉降，有机污染物沉降依赖于干沉降，氮硫磷等元素的沉降依赖于湿沉降。同时，季风和人为活动会影响大气污染物的迁移和沉降。本文的结论为污染物大气沉降的防控和土壤污染治理提供了思路。

Effect pf Atmospheric Deposition on Pollution Distribution and Element Cycling in Chinese Soil

Atmospheric deposition serves as a significant pathway for pollutant input into the soil and plays a crucial role in the element cycle.This review examines the impact of atmospheric deposition on the distribution of pollutants and element cycling in Chinese soil . The results showed that the deposition of organic pollutants, whereas heavy metals predominantly accumulate through long-term dry-wet mixed deposition.Conversely, the deposition of elements such as nitrogen, sulfur, phosphorus primarily deposit through wet deposition.Atmospheric deposition emerges as the primary input source of soil pollution in remote areas of China In addition, monsoons and human activities can affect the migration and deposition of atmospheric pollutants. The conclusions of this paper provide ideas for the prevention and control of atmospheric deposition of pollutants and the control of soil pollution.
