Air pollution from freshwater port is mainly caused by dust pollution, including material loading and unloading dust, road dust, and wind erosion dust from stockpile, bare soil. The dust pollution from a single dock characterized in obvious difference with air pollution from multiple scattered docks. Jining Port of Shandong Province was selected as a case study to get superposition impact contribution of air pollution for regional air environment from multiple scattered docks and to provide technical support for system evaluation of port air pollution. The results indicate that (1) the air pollution from freshwater port occupies a low proportion of pollution impact on regional environmental quality because the port is consisted of serveral small scattered docks; (2) however, the geometric center of the region distributed by docks is severely affected with the most superposition of the air pollution; and (3) the ADMS model is helpful to attain an effective and integrated assessment to predict a superposition impact of multiple non-point pollution sources when the differences of high-altitude weather conditions was not considered on a large scale.
淡水港口的空气污染主要由粉尘污染引起，包括物料装卸粉尘、道路扬尘以及堆场、裸土的风蚀扬尘。单个码头的粉尘污染与多个分散码头的空气污染存在明显差异。选取山东省济宁港作为案例研究，以获取多个分散码头对区域空气环境空气污染的叠加影响贡献，并为港口空气污染的系统评估提供技术支持。结果表明：（1）淡水港口的空气污染对区域环境质量的污染影响占比低，因为港口由多个分散的小码头组成；（2）然而，码头分布区域的几何中心受到严重影响，空气污染叠加最为严重；（3）当不考虑大规模高空天气条件差异时，ADMS模型有助于对多个面源污染的叠加影响进行有效和综合评估预测。
