Abstract: Urban forest parks are important urban green zones providing ecological and social benefits for citizens, and the quality of its soundscape is an important factor affecting visiting experience. Taking Fuzhou National Forest Park as an example and based on public soundscape perception data acquired from questionnaire survey, the characteristics and differences of soundscape perceptions in different functional zones of the forest park are explored, and the impacts of visitors' social, demographic and behavioral characteristics as well as four typical sound sources including birdsong, tree rustling, human speech and traffic sound on overall soundscape perception are revealed. The results show that: the dominance and harmony degree of birdsong in the forest landscape zone is the highest, but the differences in different functional zones is obvious; the soundscape pleasantness show more significant difference in different functional zones; visitors' age, occupation, educational background and visit frequency have more pronounced effects on the perceptions of the four sound sources and soundscape, and the effect on birdsong perception is the most significant, while the least on traffic sound perception; birdsong presents the most significant positive impact on soundscape pleasantness and eventfulness, while traffic sound shows the most negative impact. The study results can provide theoretical references for more specific optimization and control strategies of sound sources in urban forest parks to improve their soundscape quality.
