In order to quantitatively characterize the construction law of LID facilities, it is necessary to fit the construction area and effect of LID facilities with appropriate functions according to the simulation results, which can be applied to the genetic algorithm. The construction area and effect fitting image of single and combined LID facilities are shown in Figure 9, and the determination coefficient R2 of the fitting formula is shown in Table 4.
