In view of space demand response problems for war zone in joint operations, this paper describes the background of space demand response task planning for war zone in joint operations, analyzes the main factors in consideration of task planning in its aspects of space resources ability, space demand response mechanism, space demand response beneficial result, and cost, defines and describes a task planning model, designs a planning implementation method, and conducts case simulation based on the actual situation for war zone in joint operations. And the model and the method are verified. A certain theoretical and methodological support is provided for effective response to space requirements in joint operations in theater of war.
