The full text of the resolution is available here. The key provision is op. para. 4:
4. Authorizes Member States that have notified the Secretary-General, acting nationally or through regional organizations or arrangements, and acting in cooperation with the Secretary-General, to take all necessary measures, notwithstanding paragraph 9 of resolution 1970 (2011), to protect civilians and civilian populated areas under threat of attack in the Libyan Arab Jamahiriya, including Benghazi, while excluding a foreign occupation force of any form on any part of Libyan territory, and requests the Member States concerned to inform the Secretary-General immediately of the measures they take pursuant to the authorization conferred by this paragraph which shall be immediately reported to the Security Council
Note that this does not merely authorize a no-fly zone; use of force is generally authorized for the purpose of protecting civilians and civilian populated areas, so long as there is no ‘foreign occupation force of any form.’ This us a very broad authorization; the formulation does not necessarily exclude a limited use of ground forces, so long as that force is not of such intensity and duration that it constitutes an occupation. Over at Lawfare, Bobby Chesney has more analysis. The intervention against Lybia is set to commence shortly.
