空气信息综合管理评估系统

近年来, 重工业的快速发展加剧了空气质量下降, 环境治理变得尤为重要. 然而, 在国内外现有的空气质量评估系统大多形式单一、准确度低、评估范围有限, 并不能较精确的以多样化的形式展示空气质量情况. 本文设计实现了一套集数据收集、标准化处理及空气质量评估为一体的空气质量评估系统. 该系统采用网络爬虫从空气质量监测网站获取数据, 并对数据进行抽取、清洗、单位转化、污染物分类及多种标准化方法处理, 提高空气质量的评估精确度. 系统评估方式多样, 有按时、日、月、监测站位置及污染物种类等, 解决了大多数空气质量评估系统形式单一和评估不准确的问题. 该系统可以为用户提供实时的空气质量情况, 还可以为大气污染相关科研人员提供准确的数据预处理结果. 系统运行稳定可靠, 界面友好, 功能丰富, 能满足空气信息综合管理评估的需求.

Air Information Integrated Management and Evaluation System

In recent years, the rapid development of heavy industry has exacerbated the deterioration of air quality, and environmental governance has become increasingly important. However, most of the existing air quality assessment systems at home and abroad have single forms, low accuracy and limited assessment ranges. In other words, they cannot accurately display the air quality situation in a diversified way. This study develops an air quality assessment system which integrates data collection, standardized processing and air quality assessment. The system has the following advantages. It obtains data from air quality monitoring websites with Web crawlers and enables data extraction, data cleaning, data unit conversion, pollutant classification and data processing with a variety of standardization methods to ensure the accuracy of air quality assessment. It has numerous assessment modes, involving the assessment by hour, day, month, monitoring station location and pollutant type, which addresses the single forms and inaccurate assessment of most air quality assessment systems. It can provide real-time air quality information for users and accurate data preprocessing results for researchers. With stable and reliable operation, friendly interface and rich functions, the system can meet the need for comprehensive air information management and evaluation.
