A national co-ordination centre and "severe prohibitions" will be among the steps taken to avoid future tragedies.
The fire, thought to have been started by a barbecue, has destroyed around 12,000 hectares but is under control.
The environmental adviser for the Castilla-La Mancha regional government, Rosario Arevalo, resigned on Thursday.
One person faces charges for lighting the barbecue believed to have started the fire in pine woodland at Cueva de los Casares in the central Guadalajara province on Saturday.
Hundreds of family friends and neighbours gathered for the funerals of the 10 men and one woman who died trying to fight the fire as it swept out of control, fanned by strong winds. The only one of the group of volunteer firefighters to survive is reported to be improving in hospital
Jesus Abad, 45, who suffered first degree burns and broken ribs, told Spanish national television about his "miraculous escape".
"The hurricane of fire was enormous... I think it saw us and said 'You belong to me'," he said.
He described "a gigantic wave of fire", saying he survived by crawling under a water truck that had crashed and spilled its load.
"You have no oxygen, you see yourself burning, you see yourself... dead," he said. "The will to live saved me, because I think we all have courage."
Severe drought in both Spain and Portugal has left the Iberian peninsula susceptible to forest fires.
Spanish Prime Minister Jose Luis Rodriguez Zapatero said the plan for future firefighting would include: reinforcing communication between authorities; more severe restrictions on lighting fires in the countryside and harsher penalties.
The measures will be discussed by ministers on Friday.
