A method of demarcating noise environment function areas based on a road network and points of interest (POI), comprising: using image morphology to divide city regions into multiple sub-regions according to a road network image; taking a ratio of each POI category in the region as a regional description parameter, filtering the regional description parameter and then clustering to obtain different regional cluster categories; according to noise function area requirements and noise environment impact factors of each POI category, demarcating a noise function area of each regional cluster category and demarcating noise function areas with respect to regions along roads. The method uses a large amount of geographical space data of a city to demarcate noise function areas. The method has the advantages of a high degree of automation, a high division efficiency, and a short update cycle, and is suitable for a current urban noise environment quality assessment. |
