The invention provides a control load management system and a controller workload evaluation method. A control sector load is calculated through acquiring data at the aspects of airspace flight sortie distribution, communication record, running conditions in a control area, post staff distribution, weather conditions and the like in real time, and control load distribution is carried out, thereby acquiring a control individual load of each controller. According to the invention, factors affecting control work are quantized comprehensively and authentically, a control load result is accurately distributed to each individual controller, a second-level load standard is set through control sector load distribution analysis, and proposing and applications of a second-level load better provide data support for second-level evaluation for the controllers. According to the invention, the control load data is also applied to management operations such as performance-based salary management, controller rank and fatigue management, controller competency evaluation, probation training management, control operation and organization guidance, control operation quality management and the like of the controllers, thereby realizing effective management for the controllers.
