Narrative:

Just after starting descent into dfw, flight attendant entered cockpit and said there was a strong smell of gas in the cabin. I had the first officer go back and verify smell. He said he smelled an odor but not fuel smell. Flight attendant returned to cockpit and said smell was very strong and people were holding handkerchiefs over their noses. I then declared an emergency to dfw. I requested crash crew to meet aircraft and have a fireman board aircraft through aft stairs after we cleared the runway. By this time smell was not near as strong and after fireman boarded aircraft and found only a faint odor, decided to taxi aircraft to gate and deplane passenger. I determined that to evacuate/evacuation the aircraft was not necessary or warranted since the problem was no longer apparent.
