摘要

以重庆市两江新区为试点研究区, 利用污染物采样数据、DEM和河流等多源数据, 为获取更精细、更合理的污染物扩散预测结果, 设计了一种改进的对流扩散 (ADE) 模型, 并基于改进模型创建了新型污染物靶区数据集。实验基于新型污染物的快速溯源和精准空间定位任务, 以新型污染物微塑料为例, 对比热点网格分析方法和Catchment扩散分析模型, 定量分析了不同试验方法的表现, 并结合实际场景讨论了各方法的优缺, 为新型污染物分析方法的选择和使用提供了科学经验和依据。

Abstract

Taking the Liangjiang District of Chongqing as the study area, this paper utilizes multi-source data, including pollutant sampling data, DEM, and river networks, to achieve more refined and accurate predictions of pollutant dispersion. An improved Advection-Diffusion Equation (ADE) model is designed, and a novel pollutant target dataset is created based on the improved model. The experiment is based on the task of rapid traceability and precise spatial positioning of new pollutants. Taking microplastics as an example, the hot spot grid analysis method and Catchment diffusion analysis model are compared. By comparing the hotspot grid analysis method and the Catchment-based diffusion analysis model, the study quantitatively evaluates the performance of different experimental methods. Furthermore, the strengths and limitations of each method are discussed in the context of real-world scenarios, providing scientific insights and guidance for selecting and applying analytical methods for emerging pollutants.
