I The Marine Environmental Monitoring program is used for describing the Marine environmental monitoring work and Its literal statement. With the increasing demand of structured work task information for the Marine Environmental monitoring software system, t He implementation the Marine Environmental Monitoring Program task structuration must to account. This paper introduces the principle of the task standardization the Marine Environmental Monitoring program, and DESCR Ibes its implementation procedures. Whats more, it also takes the task standardization of seawater quality in north and sea area as a monitoring. Furthermore, it looks into the development prospects of the task Standardization of the Marine Environmental Monitoring P Rogram.
