What is claimed is: 1. A method for starting up a wind energy plant after an operation stoppage, comprising the steps of: providing a wind energy plant having a gearbox in the drive train and an operation management which can control at least one operational variable B significant for the strain of the gearbox of the wind energy plant to a desired value BS, limiting the desired value BS by a maximum value BMax, which is preset depending on a measured temperature of a gearbox component or of a lubricant for the gearbox. 2. A method according to claim 1, characterised in that one of the operational variables B significant for the strain of the gearbox is the electric power generated by the wind energy plant. 3. A method according to claim 1, characterised in that one of the operational variables B significant for the strain of the gearbox is a torque in the drive train of the wind energy plant. 4. A method according to claim 1, characterised in that the temperature T of the lubricant in an oil pan or an oil line of the gearbox is measured. 5. A method according to claim 1, characterised in that the start-up is ended when the measured temperature T corresponds to a certain operation temperature. 6. A method according to claim 1, characterised in that the maximum value BMax is increased after an operation stoppage, until it reaches a rated value BN of the wind energy plant at a certain temperature T2. 7.
