The invention provides a hot-dipped galvanized steel plate having excellent resistance to heat and high-temperature oxidation and a production method thereof. A base plate of the steel plate containsless than or equal to 0.25% of C, less than or equal to 0.080% of Si, greater than or equal to 0.10% and less than or equal to 1.20% of Mn, less than or equal to 0.020% of P, less than or equal to 0.015% of S, 0.020-0.055% of Al, less than or equal to 0.0050% of N, less than or equal to 0.10% of Ti, less than or equal to 0.10% of Nb and the balance of Fe and unavoidable impurities. A galvanized coating contains 3-5% of Si, 1.0-3.0% of Fe, 0.05-0.2% of La, 0.05-0.2% of Mg and the balance of Al and a small amount of unavoidable impurities. Compared with the prior art, the hot-dipped galvanized steel plate has the advantages that the aluminum silicon hot-dipped steel plate is produced by controlling composition of the base plate, annealing process, galvanizing liquid composition and dip-galvanizing process.
