The invention discloses a subject event updating method base and an urban multi-source time-space information parallel updating method. Suggested time-space information updating is related to multiple factors such as information sources, data models and dimension, updating methods, updating technological process, quality control and subject events, and a time-space database is updated on the basis of multi-source data integration and abnormal change discovery. On the basis of time-space database updating, a sudden event updating mechanism, an updating method based on subject event linkage and a GPU (Graphic Processing Unit) parallel acceleration updating algorithm are established, so that the dynamic information updating of urban time-space substances and time-space events is realized specific to the requirements of updating content and frequency of time-space information. The subject event updating method base and the urban multi-source time-space information parallel updating method has the advantages that
