This paper reviews the DOM pollution of water resources in China, and complements the organic matter degradation characteristics of urban water bodies in Nanjing. In this study, the photodegradation experiment and UV-visible spectroscopy measurement of three types of water are conducted, analyzed and discussed around the degradation of DOC and aromatic substances, and the DOM degradation characteristics of different cities are studied. It can be identified in this study that urban water bodies near human living areas and non-circulation have higher DOM content and are less susceptible to decomposition, which is related to human needs and transformation of the environment and human daily activities.
