MST-DBSCAN can analyze the complexity of the spatiotemporal process of the spread of infectious diseases into the evolutionary relationship between different case clusters, helping users to understand in more detail The spatiotemporal process of the spread of infectious diseases. Second, the Human Mobility Regularity-based Zoning (HuMoRZ) algorithm uses land use patterns to reflect the purpose of population movement, and takes into account the regular characteristics of population movement behavior. It is a network community analysis method for the analysis object. The urban inner districts delineated by the popular database analysis results can be used as movement control districts for epidemic prevention units to implement epidemic prevention measures such as home office, curfew and even regional blockade, thereby preventing the spread of infectious diseases. Compared with existing space control units such as large-scale city closures or small area blockades, the size of partition units is between the two, which is in line with the imagination of space control units in the literature. At the same time, the simulation results of the mathematical model of the spread of infectious diseases also confirmed that the partition of HuMoRZ is indeed the most effective among the three to delay the spread of the epidemic from the origin. Combined with the analysis of the diverse points of interest (POI) in the study area, the partition of HuMoRZ is closer to the function of the living circle, which further strengthens the practicability of the partition for the purpose of epidemic prevention.
