Acoustic environment functional area noise exceeding limit value adjusting method based on interest point data

The invention discloses a sound environment function area noise standard exceeding limit value adjusting method based on interest point data, which comprises the following steps: classifying the interest point data according to the definition of a city sound environment function area, and matching interest points to various sound environment function areas; the method comprises the following steps of: dividing an urban area by taking 4a-class and 4b-class sound environment functional areas as boundaries, dividing the urban area into a plurality of small areas, and calculating noise exceeding limit offset of the area according to the quantitative proportion of various types of interest points in the small areas; and according to the original noise standard-exceeding limit value standard and the noise standard-exceeding limit value offset of the acoustic environment functional area, calculating the corrected noise standard-exceeding limit value of the acoustic environment functional area. According to the metho
