Abstract: Comprehensive classification of national territorial spaces is fundamental to territorial planning, development and protection. First, based on the types and present classification needs of territorial spaces, a set of base classifiers, including spatial dimension and property, space usage type, value of mineral resource and scales of underground mining space and other underground spaces, are proposed for the comprehensive classification system. Next, based on the proposed base classifiers, a comprehensive classification scheme is presented, which includes 29 types and 45 subtypes of territorial land and ocean spaces. Finally, the main characteristics of and development planning for the classified territorial spaces are illustrated. The comprehensive classification system provides an important basis for the subsequent territorial space planning, development, utilization and protection.

Key words: national territorial spaces, classification, continent space, ocean space, mining space, underground space
