The invention discloses a method for obtaining the optimal heat preservation thickness of a heating directly-buried heat distribution pipeline based on economy. The method comprises the steps: firstly, calculating the annual heat loss of the pipeline in the whole heating season for the heating directly-buried heat distribution pipeline; secondly, calculating loss caused by pipeline heat loss, smoke loss provided by unit mass fuel and smoke loss of the unit mass fuel, and further obtaining fuel consumption in the whole heating season; obtaining the annual cost of the fuel according to the consumption of the fuel in the whole heating season, and calculating the annual total cost according to the annual cost of the fuel and the annual conversion cost of the thermal insulation material; and establishing a mathematical model for solving the optimal heat preservation thickness of the pipeline by taking the minimum annual total cost as a target, and obtaining the optimal economic heat preservation thickness by solvi
