Emergency material reserve coverage site selection method based on service point and risk source separation mode

The invention relates to an emergency material reserve coverage site selection method based on a service point and risk source separation mode. The invention relates to the technical field of environment planning and management. According to risk source information and river distribution information, a starting point of a risk source polluted river is obtained; determining a service point based on the obtained starting point according to the propagation speed v of the received pollutants, the required base line time t and the disposal time delta t; establishing a reliable objective function, and performing constraint; based on a particle swarm algorithm, determining an emergency material storage site selection and a corresponding assurance rate; and performing rationality check on a site selection result, and determining a final scheme. According to the method, the problem that the risk levels of different risk sources are different is considered, so that the continuous site selection problem is more suitable
