The invention relates to a preparation method of a heat-resistant anti-coking load-type gold nanoparticle catalyst. The preparation method includes: adding algae or aquatic plants into a gold precursor solution for reduction reaction in adsorption; taking out the algae or the aquatic plants to perform dehydration treatment, placing the algae or the aquatic plants in an oxygen-isolated reactor for dry distillation and heating the algae or the aquatic plants to the temperature ranging from 600 to 700DEG C; naturally cooling to indoor temperature to acquire the black-powder type solid catalyst. Compared with the prior art, a load-type gold nanoparticle catalyst is prepared by subjecting gold ions to reduction-adsorption with algae of blue algae, green algae and the like or aquatic plants of water caltrop, water nymph and the like prior to dry distillation in high temperature; the preparation method has the advantages of being anti-coking and heat resistant, neither coking nor agglomerating occurs under the tempe
