重庆市南川区PM₁₀时空特征分析与防控策略探讨

Discussion of Temporal-Spatial Characteristics Analysis and Prevention Control Strategies of PM₁₀ in Nanchuan

摘要: 基于重庆市南川区2024年高寺路(国控点)和钟楼大街(市控点)的PM₁₀季度、月、日浓度数据，浅析了PM₁₀的时空分布特征，季度、月、日浓度呈现出规律性变化。通过对地形地貌、产业布局、交通状况等因素的分析，探讨影响PM₁₀时空分布的相关要素，并针对现有防控措施，提出优化产业结构、强化交通管理、加强扬尘管控等防控策略建议，为南川区大气污染防治提供科学依据，助力改善区域空气质量。

Abstract: Based on PM₁₀ concentration data from 2024 (Gaosi Road-national control point and Bell Tower Street-municipal control point) in Nanchuan, this paper preliminarily analyzes the temporal-spatial distribution characteristics of PM₁₀, revealing that the quarterly, monthly, and daily concentrations exhibit regular variations. By analyzing factors such as topography and landform, industrial layout, and traffic conditions, this paper discusses the relevant factors influencing the temporal-spatial distribution of PM₁₀. In response to existing prevention and control measures, this paper proposes optimization suggestions including industrial structure adjustment, strengthened traffic management, and enhanced dust control, providing a scientific basis for atmospheric pollution prevention and control in Nanchuan, and contributing to improved regional air quality.
