3 Terms and definitions

The following terms and definitions apply to this standard.

3.1

Construction land

Refers to the construction of buildings and structures, including urban and rural residential and public facilities, industrial and mining land, and transportation facilities.

Land for application, land for tourism, land for military facilities, etc.

3.2
