description The present invention discloses an urban forest bioacoustic monitoring and positioning method and system based on three-dimensional space, which relate to the field of urban forest bioacoustic monitoring technologies. The method includes: placing array element units each having a function of receiving sound signals in a predetermined array in an area to be monitored and positioned; establishing a mathematical model of the sound signals received by the array element units; performing spectral peak search on an angle scope of interest using the mathematical model of the sound signals received by the array element units to acquire azimuth and elevation angles; and acquiring direction and height information of sound sources based on the azimuth and elevation angles and spatial height categories of different tree layers. The present invention can monitor and position the distribution and difference of different living things at different height layers of trees.
