A DOA-based pumping station-LID joint multi-objective optimization method, mainly including following steps: Step 1: collecting and sorting basic data of a research region; Step 2: fitting drainage parameter relationship expressions; Step 3: establishing an objective function and constraint conditions; Step 4: determining optimal solutions of a single objective function; Step 5: performing multi-objective function optimization calculation; Step 6: selecting an optimal solution. The multi-objective optimization method comprehensively considering economic and environmental benefits is particularly suitable for optimal design of installed flow capacity of a drainage pumping station at a watershed scale and layout rate of different LID measures. According to the method, regulation and storage effects of rivers, lakes, sunken green belts and permeable pavements in planning regions, and drainage effects of pumping stations are comprehensively considered, different solutions are designed according to local conditions, and a global optimal solution is quickly found using a DOA.
