The head of the Circuit de Catalunya said that only a natural disaster could threaten the future of the event.
"Only a disaster - say, an earthquake - is a problem. Forget all the rumours and headlines, we are still working as we were before," Servia told Vuelta Rapida radio.
Reports suggested that F1 supremo Bernie Ecclestone is interested in alternating the race between the Circuit de Catalunya and European Grand Prix track in Valencia, freeing up an extra spot on the calendar.
New races are being touted in Argentina, South Africa and Mexico as well as the sport returning to the United States, leading to rumours that the number of European races may be cut to five.
"If there are five then we want to be one of them, and we will fight to be," added Servia.
"We have had no communications, either verbal or written from [Ecclestone] or his organisation regarding the issues of the rumours and headlines."
The 2012 world championship begins in Albert Park, Melbourne on March 18.
