城市绿地系统对空气质量的改善作用研究
摘 要
随着城市化进程的加速，城市面积不断扩大，人口密度急剧增加，随之而来的是空气质量问题的日益严峻。工业排放、交通尾气、建筑扬尘等多种污染源共同作用于城市环境，导致空气质量下降，严重威胁到居民的健康与生活品质。城市绿地系统作为城市生态系统的重要组成部分，其在改善空气质量、提升城市生态环境质量方面发挥着不可替代的作用。本文旨在探讨城市绿地系统对空气质量的改善作用。首先，文章界定了城市绿地系统的概念，并详细分类介绍了不同类型的绿地系统。随后，文章深入分析了城市绿地系统的生态功能、社会功能和经济功能，特别是其在改善空气质量方面的显著作用。接着，文章提出了城市绿地系统规划与设计应遵循的生态优先原则、功能性原则和美学原则，为优化绿地系统布局和结构提供了理论指导。在第四章中，文章重点阐述了城市绿地系统对空气质量的改善机制，包括植被对污染物的吸附与转化、光合作用与氧气释放、蒸腾作用与温湿度调节，以及生态系统的综合作用等方面。通过系统研究，本文为提升城市绿地系统对空气质量的改善效果提供了科学依据和实践指导。

Abstract
With the acceleration of the urbanization process, the urban area continues to expand, the population density increases sharply, followed by the air quality problem is increasingly severe. Pollution sources such as industrial emissions, traffic exhaust and construction dust work together in the urban environment, leading to the decline of air quality and seriously threatening the health and the quality of life of residents. As an important part of urban ecosystem, urban green space system plays an irreplaceable role in improving air quality and improving urban ecological environment quality. This paper aims to explore the effect of urban green space system on improving air quality. First, this paper defines the concept of urban green space system, and classifies the different types of green space system in detail. Subsequently, the ecological, social and economic functions of urban green space system, especially its significant role in improving air quality. Then, the paper puts forward the ecological priority principles, functional principles and aesthetic principles that should be followed in the planning and design of the urban green space system, which provides theoretical guidance for optimizing the layout and structure of the green space system. In the fourth chapter, the paper focuses on the improvement mechanism of urban green space system on air quality, including the adsorption and transformation of pollutants by vegetation to pollutants, photosynthesis and oxygen release, transpiration and temperature and humidity regulation, as well as the comprehensive effect of ecosystem. Through systematic research, this paper provides scientific basis and practical guidance for improving the effect of urban green space system on air quality.
