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.
