为研究街道行道树种植设计策略,本文分析了街道颗粒物扩散的研究方法,行道树种植对街道颗粒物扩散的调控机制,并在此基础上系统梳理了行道树参数对街道颗粒物扩散的影响。颗粒物扩散的研究方法主要包括现场实测、风洞试验和数值模拟3种方式,各方法优势、局限性有所不同,数值模拟法是当前研究的主要途径。调控机制主要包括空气动力学和叶片吸滞2种途径。影响因素主要包括行道树种类、树高、树冠形状和密度、种植方式等。不同种类的行道树滞尘能力存在差异;树冠高度、树冠形状会影响街道的通风能力,进而影响颗粒物的扩散能力;不同株距的种植方式对颗粒物浓度的作用效果呈现出非线性特征。未来,可从多参数耦合、多功能权衡和AI方面对其深入研究。本文为城市的可持续发展和人居环境建设提供参考。

To study the design strategies for planting street trees, the research methods of street particulate matter diffusion, the regulatory mechanism of street tree parameters on street particulate matter diffusion were analyzed, and on this basis, the impact of street tree planting methods on street particulate matter diffusion was systematically sorted out. The research methods for particulate matter diffusion mainly include three approaches: field measurement, wind tunnel tests, and numerical simulation. Each method has its own advantages and limitations. Numerical simulation is currently the main research method. The regulatory mechanisms mainly include 2 pathways: aerodynamics and blade absorption. The influencing factors mainly include the types of street trees, tree height, tree crown shape and density, and planting methods, etc. The dust retention capacity of different types of street trees varies. The height and shape of the tree canopy can affect the ventilation capacity of the street, and thereby influence the diffusion capacity of particulate matter. The effect of planting methods with different plant spacings on particulate matter concentration shows nonlinear characteristics. In the future, in-depth research can be conducted on it from the aspects of multi-parameter coupling, multi-functional trade-offs and AI. This article provides a reference for the sustainable development of cities and the construction of human settlements.
